If you have a thyroid problem then there’s also a good chance that you are taking other prescription medications.
How do I know? Because a thyroid issue puts you at high risk for problems like high blood pressure, high cholesterol, depression, and more.
But did you know that these prescription medications used to treat these problems can actually make your thyroid worse?
It’s true.
And in a vicious cycle, you may be taking medications to treat problems caused by your thyroid that only circle back to make your thyroid even worse.
Today we are going to go over this list to make sure you aren’t taking any and what to do if you are.

4 Ways That Prescription Medications Interfere with Thyroid Function
There are 4 main ways in which prescription medications can interfere with thyroid hormone function.
And when I talk about thyroid hormone function what I really mean is how well your thyroid is working.
Different medications interfere with thyroid function in different ways which means they can sometimes slip under your radar.
Let’s go over these categories so you better understand what I mean:
Category #1. Medications that Block T4 to T3 Conversion.
T4 to T3 conversion is the process by which your body takes the inactive T4 thyroid hormone and activates it by turning it into T3.
And since T3 is the strongest and most important thyroid hormone, if your body can’t do this, you’re going to experience problems like weight gain and hair loss.
Surprisingly, many medications interfere with this process leading to low T3, including some that are used to treat common conditions:
- Beta-blockers – This is a class of medications used to treat high blood pressure, migraines, and even anxiety (1). Because hypothyroidism leads to high blood pressure, it’s not uncommon for thyroid patients to be taking something for their blood pressure. If that’s you, make sure you check with your doctor to see if you are taking a beta-blocker because, if you are, it could be making your thyroid worse. The good news is that there are many other high blood pressure medications available so switching to one of these is often pretty easy. But if you want to do something even better, go for lifestyle changes that can normalize both your thyroid and your blood pressure. I have articles and resources that can help with both.
- Narcotics – All types of prescription narcotics (such as Vicodin, Percocet, and more powerful narcotics) can block thyroid conversion (2). More concerning than this is the fact that low thyroid function can actually cause chronic muscle pain and fibromyalgia. So you may be taking a pain medication to treat pain related to your thyroid that only serves to make your thyroid worse. I know that may seem dizzying, but I’ve seen it happen. It’s also worth noting that some thyroid patients, especially those with Hashimoto’s, take low-dose naltrexone that blocks narcotic function, so keep that in mind. Over-the-counter anti-inflammatories (3), like ibuprofen, do not cause this issue and are preferable if you need to take something.
- Antidepressants (4) – This is a huge one! How many of you are taking antidepressants and have no idea that they can make your thyroid worse? Roughly 24% of American women take antidepressants and this number is even higher for hypothyroid women because hypothyroidism causes depression. The best way to solve depression is not to take antidepressants, but to optimize your T3 level! This is exactly why T3-only medications like liothyronine and Cytomel are sometimes used to treat this very condition. The problem may not be depression but thyroid function, instead!
- Methimazole – Methimazole is designed to treat hyperthyroidism (high thyroid) so it’s not surprising that it blocks thyroid function. What you need to understand, though, is that taking methimazole will take your thyroid from the hyper state to the hypo state and you may experience the symptoms of hypothyroidism in the process.
- PTU – PTU is another medication used to treat hyperthyroidism but it isn’t used as much nowadays as methimazole is preferable.
Category #2. Medications that Block TSH Production.
These medications work by interfering with how your brain communicates with your thyroid gland.
Many thyroid patients are focused solely on their thyroid gland which is situated in their neck because that’s where most problems arise.
But there are plenty of thyroid patients who have thyroid problems because of issues in their brains and pituitary glands.
If your brain can’t communicate with your thyroid gland then it doesn’t matter how healthy your thyroid gland is, it will never get the message to produce thyroid hormones.
So this is an important and often overlooked cause of thyroid problems.
Medications that interfere with this process are difficult to trace because pituitary-related thyroid problems can be easily missed with standard thyroid lab tests.
- Steroids – Steroids are often given to patients as prescription medications to help lower inflammation in certain diseases. Most doctors know not to use these powerful medications long-term, but it is sometimes necessary. Steroids have a suppressive effect on the brain which reduces TSH production and this effect gets worse the longer you use the steroids. By the way, this side effect can also occur if you are using topical steroids as well! Topical steroids in gels or creams are typically not absorbed very well (5) but they can be depending on where you place them. If you put topical steroids on your face, under your eyes, around your nose or lips then you are absorbing a lot more than you think and those steroids may be causing problems with both your adrenal glands and your thyroid.
- Dopamine agonists – Dopamine agonists are usually used to treat Parkinson’s disease so they are not very common, but they can suppress TSH function (6).
- Metformin – Third on the list is metformin which is a very common medication used to treat diabetes and insulin resistance. More recently it’s also being used as a treatment to extend lifespan and for obesity. What’s really interesting about metformin is that it was once thought to cause problems with thyroid function. More recent research suggests that instead of having a harmful effect on the TSH, its effect may actually be beneficial (7). In other words, metformin may actually improve thyroid function. I’m of the opinion that it probably does have a beneficial effect on thyroid health, especially in cases of Hashimoto’s, but we are still figuring out exactly how it works.
Category #3. Medications that Block Thyroid Hormone Production from the Thyroid Gland.
The medications we’ve discussed so far have impacted your body’s ability to activate thyroid hormone and its ability to stimulate the thyroid gland, but this one is a little bit different.
These medications work by damaging the thyroid gland directly.
And if your thyroid gland isn’t working properly then it doesn’t matter if your brain is communicating with it or if your body can activate thyroid hormone.
These medications are not as common as some of the others we’ve discussed so far but you should still be aware of them:
- Potassium iodide – This type of potassium is typically used for dermatology procedures and is not the type of iodine that you are probably familiar with. Unless you are getting frequent dermatologic procedures, it’s unlikely you’ve been exposed to this medication often enough for it to cause problems.
- Lithium – Lithium is definitely more common because it’s used to treat mood disorders and bipolar disorder. The problem is that long-term use of lithium, especially if used in high doses can permanently cause thyroid damage (8). For this reason, everyone who uses lithium is required to have their thyroid checked at regular intervals. What’s interesting here is that certain thyroid medications (like Cytomel and liothyronine) can actually help treat bipolar disorder. So if you are using lithium for bipolar disorder and you haven’t tried those therapies you may want to look into them!
- Amiodarone – Amiodarone is usually used to treat certain heart conditions and is not frequently used nowadays. Like lithium, doctors know that amiodarone can cause thyroid problems so they usually keep an eye on thyroid function when prescribing it.
Category #4. Medications that Block Thyroid Medication Absorption
This is probably the biggest section of all because just about every single medication out there has the potential to interfere with thyroid medication absorption if taken incorrectly.
This is the very reason that you’ve been instructed to take your thyroid medication on an empty stomach if you’ve been prescribed thyroid medication.
While all of this is true, you should know that some medications cause more issues with absorption than others and it’s these that really you need to be aware of.
The medications we are about to discuss can block the absorption of all thyroid medications, not just levothyroxine or Synthroid:
- Acid blockers and antacids – What’s dangerous about these medications is that they are available over the counter and many thyroid patients are taking them for acid reflux. Pretty much any medication that reduces stomach acid can have a negative effect on thyroid medication absorption as well as the absorption of thyroid-supporting nutrients like magnesium (9). Unfortunately, because these medications suppress acid production for hours after taking them, they can still interfere with thyroid medication absorption even if they are taken hours apart. If you are taking one, do your best to get off them and use natural treatment options instead.
- Fiber – These are often used to treat constipation which is another side effect of low thyroid function. Do you see the connection here? Many thyroid patients are taking medications to treat the symptoms of thyroid dysfunction which only serve to make their thyroid worse when they should be focusing on optimizing their thyroid instead! These fibers work by pushing stool through the GI tract to help with bowel movements but they can slow down the absorption of thyroid medication. By the way, this effect also applies to some weight loss supplements like glucomannan as well.
- Orlistat – This weight loss medication blocks the absorption of fat in the gut but happens to also cause issues with thyroid medication absorption. It’s not as common as other weight loss medications, but some people still use it.
- Cholestyramine – Cholestyramine is what is referred to as a binder and it’s usually used to help lower high cholesterol. It’s also sometimes used to treat diarrhea and integrative doctors will occasionally use it to help with detoxification. While it can have positive effects, one of the downsides to using this medication is that it can block your thyroid hormone from being absorbed.
- Calcium carbonate – This is used to replace low calcium and it’s commonly used in people after thyroid removal surgery who accidentally had their parathyroid glands damaged. If you are taking calcium of any type, including from your diet, you must take your thyroid medication at least 4 hours away from it.
- Ferrous sulfate – This medication is used to replace low iron levels and to treat anemia. Iron, much like calcium, is a strong binder of thyroid hormone (10) and must also be taken 4 hours away from thyroid medication.
- Sucralfate – Sucralfate isn’t used very often but when it is it is typically used to treat inflammation in the stomach (gastritis) or stomach ulcers.
- Estrogen – Estrogen doesn’t directly impact thyroid medication absorption but it can impact how well your thyroid medication is being used by the body. It does this because it increases thyroid hormone-binding globulin which can bind to free thyroid hormone and limit how much is available for your body to use. I’ve included it here because it doesn’t fit neatly into any of the other categories. But what you need to know is that if you are taking estrogen or other sex hormones, you may need to make adjustments to your thyroid medication dose.
Make Sure you Double Check ALL Of your Prescription Medications
The moral of the story is that you should be very aware that prescription medications can interfere with your thyroid.
And some of the very medications that you’re taking may be used to treat the problems caused by your thyroid.
My recommendation is to take a close look at all of the prescriptions that you are taking to see if any are causing problems.
If you find that any of your medications are found on the list above then ask your doctor if you can switch to another type of medication in a different class.
For instance, if you are taking a beta blocker for high blood pressure then you may want to switch to something like an ACE inhibitor.
The same logic applies to other medications as well.
And making these small changes can increase your thyroid function by 10-20% which can have a huge impact on your symptoms.
But I can give you some even better advice:
If you focus on improving your thyroid you may find that conditions like weight gain, high cholesterol, depression, and high blood pressure start to vanish.
So instead of jumping to prescription medications, try optimizing your thyroid first.
It just so happens that your thyroid is very responsive to dietary changes, exercise, and even supplements.
If you don’t know where to start then I’d recommend checking out this article next.
Now I want to hear from you:
Did you know that these medications can cause issues with your thyroid?
Are you taking any of the medications listed above?
If so, did you notice a change in how you feel or how well your thyroid was working after you started it?

If I take levothyroxine at night does my statin interfere or is it not advisable to take together? I like the idea of taking the thyroid med at bedtime instead of in the morning.
Hi Patsy,
It’s not advisable to take them together.
Hi Dr Child’s. My integrated gp has prescribed me dhea to help with my adrenals. Will that interfere with my ndt?
Hi Sally,
It shouldn’t interfere with your NDT but it can cause other issues.
Hi Dr Childs, can i ask what other issues dhea could cause please?
Also could you point me to your posts on weight-loss resistance too please.
Hi Deborah,

What issues are you referring to? I’ve been on DHEA for the last four years and it’s helped with my energy levels tremendously. I haven’t had any bad side effects.
DHEA is a precursor hormone that can be turned into estrogen or testosterone by the body. In some situations, it can result in an excess of these hormones and cause symptoms/issues.
I would like to know your thoughts on using betahistine for tinnitus/vertigo and does it interfere with my thyroid medication? And if so, should I stop taking it?
Hi, I’m on HRT. Does this mean my Thyroxine is not working well? According to my last bloods my TSH is a little high but my T4 is normal. They do not test for T3 under normal circumstances in the NHS in THE UK
Hi Siobhan,
It depends on what type of HRT you are taking and what your dose is.
Great information. Thank you.
I’m taking Mirtazapine which is classified as antidepressant. My PCP has never mentioned that this may interfere with my T3 conversion. Is Mirtazapine one that does interfere? My T3 is low at .78. I have lots of anxiety and take Lorazepam and melatonin for sleep in addition to Levoxyl and Liothyronine. Only other problem has been a lot of hair loss.
Read the fine print of the medication pamphlet, I just recently notice under the note in the pamphlet that this medication interferes with iodine something Dr doesn’t know tweet about
I stoped taking it 3 months ago and starting to feel much better, remeron was the brand name of antidepressant
Are you currently accepting new patients?
Hi Molly,
I am not.
Hi,
I was diagnosed with Graves’ disease and I tried taking all different thyroid meds and have had really bad side effects to them all and felt like crap on them. My TSH is high but my T3 and T4 are both in normal range. Any help to figuring out why I feel like crap taking these meds to the point of anxiety and panic attacks. I have stopped my meds.
Hi Lisa,
It’s hard to say for sure without a lot more information but my guess would be that it’s a dose related issue.
I’m to be taking Prozac 20 mg and Olmesartan Medoxomil 40 mg and suffer from severe anxiety and should be taking clonazepam per my pcp 1 mg 3x daily as I can’t sleep. I’ve just beep it on Armour 30 mg. Any of this causing problems with Armour?? Thank you
Hi Nancy,
Those medications may interfere with thyroid function. Please see this article: https://www.restartmed.com/prescription-medications-that-block-thyroid-function/
I’ve been diagnosed hypo (no antibodies) because My TSH is consistently at about 6. I suffer from fatigue, depression, brain fog and have tried taking both levothyroxine and liothyrine on different occasions. But even at very low doses these meds give me extreme anxiety. Anti-depressants are the only thing that allows me to function. Would love to be off them, but nothing else works.
I take thyroid medicine called levothyroxine 100 mcg once a day and it’s making me gain a lot of weight, I have hypothyroidism.
Hi Jeannie,
Unfortunately, that is quite common. Please see this article which outlines why that occurs: https://www.restartmed.com/levothyroxine-weight-gain/
Hello~ I take 50MCG Levo but feel I could do more. Always been around 115-118 lbs @ 5’4″. need to lose 20-25lbs to get back. What would you suggest?
Hi Pamela,
You would want to start with a complete set of thyroid labs to see if you do need more: https://www.restartmed.com/normal-thyroid-levels/
Dr Childs
I have hypothyroidism hashimoto. I’ve been dealing with severe anxiety and stress recently. Dr prescribed me hydroxyzine. That made me more anxious. Then they prescribed me propranolol for anxiety. I feel horrible that I went to the ER for palpations. Now I seem to have all the symptoms of being hyper! What has happened? I’m on 75mg of armour. I feel like I’m over medicated.
Hi Julie,
It’s possible that you are over medicated but you’ll need to have your labs tested to be sure. You’ll need your doctor to order your thyroid lab tests and that will tell you if you are.

Hello Dr. Child’s! There is one more category that I would like information about. It is surgical procedures (ie: Roux-N-Y gastric bypass) and digestive tract disorders that interfere or impair with absorption or dosages of thyroid medications. Would you please update this article or give a link to other articles you have written about this specific concern? Thank you for all the important information you share with us!
Hi Giovanna,
You are 100% correct that gastric bypass will impact thyroid medication absorption but I wouldn’t classify it as a prescription medication which is why it isn’t included in this article. Having said that, I still think writing about that topic is a good idea so thank you for the suggestion 🙂
I started taking my thyroid meds at night (Tirosint & Cytomel) to be sure they are away from any vitamins. My husband just passed away and my Primary doctor prescribed a low dose of Zoloft (25 mg) during the day and Zanax at night for sleeping. It has only been 2 months since I started. My hair has started to fall out even loosing eyelashes. Of course it could be stress. Should I speak to the primary of my endocrinologist to start to wean myself off of these meds?
A side affect of Tirosint and Cytomel is hair loss. Have you tried an NDT. I had the same issue when I took synthetics T4 T3. I am very sensitive to them. They even tried giving me Time released, but with it being a synthetic same issues. I am very senstive to synthetic T3. I had always taken Armour 90mg, but for some reason my Doc changed me to NP Thyroid which was recalled for super potency and all my problems started Last year when this happened. I am now back on Armour. Since the switch my hair loss is almost gone in a few weeks, my eyebrows are growing back. I get 90 MG and split them in half. I have started with 45mg in the morning and I will be working my way back up, splitting the other 45 in half and taking smaller doses a couple times a day. Hope you can figure it out and Good Luck
Hi Rita,
It’s probably more related to stress but it would still be a good idea to see your doctor and get your labs checked to see if you need to make any changes.
Great info as always. Thank you.
I never had any idea that PPIs could interfere with thyroid med absorption. I also just started HRT via pellets that my doctor slices me and puts into my backside. My TSH has been a little too low for months, but my T3 was good and I think my T4 was slightly low or vice versa. My pcp told me to stop taking the cytomel. I was taking 5 mg a half every other day. It definitely gave me a little more energy and made me less lethargic. So I’m worried that I’m going to get lazy and tired again now that I stopped using it about a month ago.So now I’m just taking my armor thyroid. When I first was diagnosed I was put on Synthroid and then the generic version and they really made me extremely anxious. The armour thyroid has definitely helped with my anxiety levels.
Hi Colleen,
Acid blockers are a big no no for those with thyroid problems 🙂 Please see this article: https://www.restartmed.com/acid-blockers-thyroid-problem/
Hi Dr. Childs,
On your list of meds that interfere with thyroid medication is estrogen, which is what I take each morning and evening in bioidentical form, transdermally. Because I want to continue to take estrogen, would you suggest spacing these meds apart a few hours?
Hi Lisa,
Estrogen impacts thyroid function because it impacts thyroid hormone-binding globulin. In other words, this effect will still occur regardless of when you take your thyroid medication in relation to your estrogen and regardless of HOW you take your estrogen.
An endocrinologist tried treating me for 5 years with not good results. Every time I started to take the Synthroid or Levothyroxine I would have heart palpitations and would have to stop or take it every other day BUT nothing helped. I met a compounding pharmacist who told me I needed estrogen but the bioidentical kind. Once I started taking that, I could take the Levothyroxine with no palpitations. I also take a bioidentical progesterone so I don’t become estrogen dominant. BUT, today I read about how estrogen can inhibit the absorption of my medicine. I’m confused. My labs are normal. I take 75 mg of Levothroxine and 10 mg of Cytomel each day. I take them both in the middle of the night to avoid interference with my vitamins. What say you, Dr. Childs? It’s been years since I’ve been on the estrogen (I’m 69 now) so maybe I could go off of it. Please advise.
Hi Connie,
I’m not really sure I follow the question, are you asking if you can get off of your thyroid medications?
I was given CORDARONE Amiodarone for A-Fib from 2016 to 2020. High doses of it and loaded several times in hospital.
The doctors never told me of the side effects nor did any follow up tests. I now have hypothyroidism due to this drug.
I know that there is a half life and that it remains in my cells and tissues and organs for years after stopping.
My question is
How can I detox and will it every leave my body.
Can the Hypothyroidism be reversed and would I be able to come off my NDT.
I have gained so much weight due to CORDARONE Amiodarone toxicity.
I have most of the side effects from it.
Can or will I be able to repair my Thyroid problems
Hi Christine,
Unfortunately, some of the damage may be permanent but there will be no way to know for sure unless you are able to get off of it and see how much thyroid function can be restored. You will need to talk to your cardiologist (or whoever prescribed it) to see what other options are available for your a fib.
Hi Christine,
I was having Afib because of my competitive running. I am 52, was loaded with the damn Amiodarone for 3 nites +days in hospital, and for a month oral Amiodarone thereafter. The doctor did not say one word abt thyroid to me. I managed to cure myself of Afib with 20,000mg of ascorbic acid, 6000 mg lysine and 2000mg proline daily for 57 days. The is the linus pauling therapy for cardiovascular disease. No Afib for 11 months now. Just trying to gradually phase in the Armour for the induced hypothyroid.
Hi David,
Glad you found what worked for you!
Thank you for this article! I take Tramadol maybe once or twice per week for chronic back pain. I believe that it is an opioid narcotic. I just wasn’t sure if it is considered one that can block thyroid function. I don’t take it often but I hate to cause more issues for my poor thyroid.
Hi Carrie,
If you are using it infrequently it probably has only a minor impact.
Hi….
As I’ve said before your email topics come at the most perfect time.
Yes, I understand no calcium, iron or magnesium supplements.
I did not know “potassium iodide was one of them. I was given a custom iodine supplement ( potassium iodide an iodine titrate = 12.5 mg). My iodine lab went to 859. I stopped but not bec I follow the conservative range. Because people take large amts every day as you mentioned, I do not understand how much is the optimum range to be at. I was going to start back on my iodine today but read this email saying potassium iodide was not good. Now what do I do? Could go back to my Nasent iodine extract at 1950 mcg. Iodine was the cause of my losing T4/T3 per my own testing. It also resolved the headaches I had everyday for years. Always told I was fine. Over a asbestos over. What a bunch of idiots! Always knew it was either deficiency or chemical imbalance. Resolved two major issues. Can’t wait to write on the website about every single doctor I saw.
Also….
As for anti depressants, was going to start Wellbutrin. Search said no interference w thyroid meds. Yes, no?
I know it’s better to not but I’m not having fun over here.
Cytomel not working and dose too low. (digestive disorder). Waiting for my dr. to prescribe SR T3 for me. I don’t think he knows allot about compounding.
Thank you
Hi Cindy,
Wellbutrin works via a different mechanism than traditional anti-depressants and shouldn’t cause issues with the thyroid, at least not to the same degree as SSRI’s.
My daughter is on anti-depressants. As her mother, I have been on thyroid medication since I was pregnant with her (26 years).
I would love to see her not have a problem with her thyroid, especially with the T4 to T3 conversion. She should probably ween of her meds??
Hi Ann,
In my experience, depression can almost always be treated without the use of anti-depressants and if she can avoid taking them then that would be better for her health overall.
I take an BHRT: Bioidentical hormone treatment that is a combo of Estradiol, Progesterone and Testosterone. Is this not good due to the estradiol?
Hi Martha,
It’s not really a good or a bad thing by itself. Whether or not it’s good depends on your body and whether or not it helps you feel better. If it does, then you should keep in mind that it may impact your thyroid levels so that should be accounted for.
Thank you for consistently providing such empowering, useful information. Is Lexipro considered an antidepressant? It was given to me as an anti-anxiety med but I’m wondering it it could be contributing to my conversion problem. I have tried many different doses but no matter what I go on my T3 seems to hover between the mid-twos and upper twos range. This was the case for a while before I started the anxiety meds but I’m just curious if that could be counterproductive to my goal of trying to optimize my T3. I’ve ordered your thyroid daily essential vitamin in the hopes that maybe that will help something budge. When I first started thyroid meds my body seemed to be converting very well. I’m still trying to figure out how to support it to get it back in a more optimal range. Mainly, I just need that pep back in my step!!!
Hi Rachel,
Yes, Lexapro is an anti-depressant.
I have been on different thyroid meds since I was 6-7 yrs old. I’m 63. I went on supplements and off of all thyroid meds but still don’t feel well with thick tongue, pain tingling in hands and puffy eyes and weight gain among fatigue. I just read about B12 and I’ve been taking the wrong one. My doctor told me in March 2021 my labs look great. I told him I’m not doing well. So I stopped synthroid. I did try Raw thyroid but that was no help. I am 40-50 pounds overweight and started fasting and auto immune diet. I have had pituitary tumor but now that’s gone.
Hi Dr,
I have had hashimoto’s for 21 years now – medication I take daily
Levothyroxine 0.05mg x 4pw &0.1mg x 2pw Liothyronine sodium
/ Prolia 60mg/mL injection 2xpa / Hemp oil capsules /
Is it safe to take Moringa supplement
Thanks.
Hi Teresa,
It’s probably a good thing for thyroid function but there aren’t a lot of studies that show one way or the other.
Dr. Childs,
It seems most of your topic articles are not based on those of us with hypothyroidism due to cancer and total thyroidectomy. Your list of antidepressants seems very short, is that all that I need to be concerned about? I currently take two prescriptions and have for over 20 years. I had my TT 11 years ago. One is an angiotensin II receptor antagonists due to MI in 1998, the other is an SSRI antidepressant medication that works in the brain. It is approved for the treatment of major depressive disorder (MDD) and generalized anxiety disorder (GAD).
I have taken Protonix for so many years I cannot remember. Surgery is out of the question, I have a hiatal hernia, slow motility, and nutcracker esophagus. Can be very painful so once in a while I do take a Sucralfate that I always take at a time when it won’t interfer with the Armour, and this is the shortlist of meds I take.
Any additional help would be appreciated.
Most of what I found in this particular article seems to be related to levo and others of its sort. I am currently taking Armour, not my favorite, but with all the other NDTs facing hurdles, this is what I am stuck with. I did start with levo after my surgery then switched to Nature-thyroid.
Hi Rhonda,
All of my articles that talk about hypothyroidism are also relevant to those without a thyroid from any cause. So this information is 100% relevant to you as well as most of my other articles (95%+).
Not all anti-depressants cause issues but those that are SSRIs or SNRIs have the potential to.
Hi Dr. Childs,
I was medicated liotirinina (25mg) and and also Levotiroxina Sodica(100mcg) and I take half of each tablets in the morning before any meals. And as you said in your article yes, I also was given Metformina (850mg) 1 pill a day. It has been almost a year since I’ve started to take them but unfortunately they don’t help. The results in my test blood are almost the same. And every time I have an appointment with my doctor I ask him to change the medicine . Now after reading your article I understood why I have no results.
Can you suggest me anything else instead of those medications?
Thank you so much.
Hi Sabina,
I’m not sure if all options are available in your country but you can check out this article for more suggestions: https://www.restartmed.com/thyroid-medications-that-work/
Is Setraline HCL 100mg. (1and 1/2) daily ) (Zoloft ?) one of the anti-depressants on the “avoid” list ?
AND – I take pramipexiole nightly for restless legs syndrome — a problem for thyroid ?
Hi Karen,
Yes, sertraline is an SSRI which means it’s on the list. I am not sure about pramipexole, though, as I haven’t studied it.
Thank you so much Dr. Childs! What are your thoughts on calcium channel blocker medication (for example, amlodipine) used to treat high blood pressure? It does not appear on your list of potential harmful medications for the thyroid. Is there any chance it may block iodine and its functions related to the thyroid? Thank you!!
Hi Jackie,
As far as I know, calcium channel blockers do not interfere with thyroid function. In terms of treating hypertension, it’s always best to try and reverse it, though, if possible.
Hi Dr. Childs,
I was diagnosed with Graves in January 2020 and have been taking Methimazole since. Lately, I have been trying to follow your recommended diet of clean eating, I try really hard, but not the best at it. I’ve gone down from 15mg to 2.5mg every other day now.
The TSH levels were high the last 2-3 times I got lab work done. Could this be because I’m on Methimazole?
-Should I stop going to my Endo and stop Methimazole altogether?
-What can I do to balance out my TSH and TSI so my Endo can take me off of Methimazole?
Hi Riley,
I’m not able to give recommendations on how to adjust your dose of medication but if your TSH is increasing that means you may not need the methimazole any longer.
Does this mean that lugols is a no no?
Hi Tracy,
Not necessarily, some people do benefit from higher doses of iodine. You just need to be aware of the potential consequences of high dose iodine before using it.
I’m on a low dose beta blocker, atenolol, for NDPH. I’m also on compounded T4 and straight T3. So it’s rendering the T4 useless, correct?
Since I’m on T3, do I not have to worry about conversion being blocked? Or would you still recommend trying a non-beta blocker?
Hi Elizabeth,
It’s not rendering the T4 useless but it may be negatively impacting your ability to convert T4 to T3 efficiently. You’d only really need to try to switch medications if you are experiencing hypothyroid symptoms or feel that your thyroid is not optimized.
I have autoimmune hepatitis which started in my thyroid. I’m taking Propranolol because in the beginning I had esophageal varices. Now I’m also taking Pantoprazole for acid reflux and gastritis. Is it possible to still take these while taking levothyroxine, if the two are taken in the morning and thyroid at bedtime?
Hi Shelley,
They can be used together but it’s not a good idea for the reasons listed here: https://www.restartmed.com/acid-blockers-thyroid-problem/
You might also see better results by switching to a liquid version of thyroid medication such as Tirosint-sol given your esophageal issues: https://www.restartmed.com/tirosint-sol/
I take 10mg of Paxil every night along with a probiotic ( Align). Can I take my Synthroid (100mg) with them at night?
Hi Kathleen,
You should never take any other medications or supplements at the same time as your thyroid medication regardless of the time of day that you take it.
I have recently been prescribed Sulcrafate and Protonix for multiple gastric ulcers and a larger cratered duodenal ulcer. I have been experiencing tachycardia and PVC’s, which are typical symptoms of my hypothryoidism (not ‘textbook typical’) along with elevated TSH. I am not sure though what else to take in place of these so the ulcers will heal?
P.S. I am a huge fan of your supplements and blogs! Thank you!!!!
Hi Marie,
I would say tachycardia and PVCs are unusual for those with hypothyroidism and I would look to other causes first. The elevated TSH is problematic, but those other symptoms could be related to your heart. The medications you mentioned tend to cause issues with thyroid medication (not the thyroid itself) and one of their bets use cases is for ulcers so I wouldn’t jump to make any changes right away without further evaluation.
I was diagnosed with GERD,I had barretts esophagus syndrome. My GI doctor has me on Pantoprazole-I take 20mg one hour before dinner. Sucralfate at bedtime. I take Armour Thyroid 1Gr 60mg at 7am daily. Bupropion 150mg breakfast 10am . I know some of these meds are on the list but I have to take them . could the spacing them apart help prevent any issues with absorption of my Armour ?
I have a appointment with a endocrinologist in a couple weeks. My PCD was monitoring my armour but she doesn’t know how to lower my dose from 60mg . She said on my last blood work one of my numbers was to low like 0.15 …. it was lower than chart guidelines. She said the pills can not be cut . Should I ask about liquid thyroid med. I also take Florajen probiotic once daily.
Hi Beckie,
Unfortunately, it doesn’t really matter how far away you take your pantoprazole from your thyroid medication as it will still interfere with its absorption. Also, if your doctor reduces your dose it is highly likely that you will feel considerably worse. Generally speaking, your TSH is not that low to warrant changes unless you are experiencing hyperthyroid symptoms: https://www.restartmed.com/low-tsh-vs-suppressed-tsh-on-thyroid-medication/
Dr. Childs,
I take 25mg. of Atenolol at 9:00pm daily. It hasn’t changed my thyroid labs at all. I take NP thyroid at 2:00 pm and 3:00 am. I read that it has very little effect on thyroid hormone. At this small dosage taken many hours from my thyroid medication I am hoping it is okay to continue. What are your thought on this?
Hi Marilyn,
Atenolol has a half life of about 6 hours so it will stay in your system for 30 hours at least. Whether or not it’s having a significant impact on thyroid function is another story, but there’s no question that it’s available in your body to cause problems when you take your thyroid medication.
Hi Dr Childs
I have Hashimoto’s Thyroiditis, diverticular disease, Osteoporosis with Multiple Spine fractures, latest fracture T5 just from sneezing 3 Weeks ago, for the past 5 Years GP/CONSULTANTS have put me on Oramorph liquid and last Week whilst in Hospital Zomorph 10mg slow release capsules. I don’t like taking the morphine drugs but I sure need the pain relief as I am in Constant chronic pain. I have liquid levothyroxine because I had problems with every brand/generic of levothyroxine tablets. Although, I still have a problem with the liquid levothyroxine because it causes loose stools……I won’t take the 7.5mls Daily that was suggested because of the loose stool issue so I take only 5mls…..I didn’t have any levothyroxine recently whilst in Hospital because they didn’t have the liquid levothyroxine. After a Week my TSH was 5.8, ft4 16 so not bad considering that I hadn’t taken levothyroxine for a Week and with being ill irregularly for 3 Weeks. Question is does Morphine affect Thyroid function
Hi Sue,
Yes, morphine can negatively impact TSH and T3/T4 levels.
I’m a little surprised that you didn’t mention drugs containing fluoride. Fluoride can block the absorption of thyroid hormones because it goes to the same cell receptors as they do. One big offender is the antibiotic ciprofloxacin but there are others. Some vaccines may also contain fluoride. In general, fluoride from any source should be avoided by everyone because of its many toxic effects. But for the purpose of this topic I believe that anyone with thyroid-related disorders should be especially vigilant. I’ve even spoken to my pharmacist about this and asked that she put a note in my record there that no fluoride-containing drugs were to be dispensed to me.
Hi Suzanne,
I was going to write about fluoride on its own, but, you’re right, there should be a reference to those medications in here as well.
Hello, I’ve tried many of your weight loss supplements and asked for more information on the issue of having had RAI due to Graves and my constant battle with medication levels. I am going through Menopause as well and cannot lose weight despite trying so many things and staying the course as well. I did not receive any response related to the menopause issue and that definitely impacts weight loss. I SO wish there was more information on that! Many of the symptoms overlap. I am now on HRT – .0375mg Estrodial, 100mg Progesterone due to hot flashes, migraines…the list goes on. I’m at a loss and did not refill your weight loss supplements because I’ve been on them for months with no results. Hoping to get more information though and perhaps there are alternatives? Thank you.
Hi Erika,
When it comes to weight loss after thyroidectomy and RAI, it will almost always come down to your thyroid medication dose. Supplements will certainly help, but they won’t be strong enough to take the place of a fully optimized thyroid medication routine. Even with all of this in place, you’re going to need to be nearly perfect with your diet and exercise plan. This is just the reality for those without a functioning thyroid gland who are trying to lose weight. It’s still possible, it will just require a lot of effort on your part.
