The Case for Levothyroxine Injections
There’s no doubt that if you are a thyroid patient you’ve heard of levothyroxine.
Levothyroxine is the most standard and frequently prescribed medication to treat hypothyroidism (and your doctor’s favorite medication to use even though it isn’t the best). of all types
Today we are going to be discussing levothyroxine but with a bit of a twist.
And this twist makes all of the difference and you’ll see why as we talk about it.
We are going to discuss the benefits of levothyroxine injections.
You might be conditioned to think that levothyroxine, in all it, is not a very good thyroid medication. s forms
And while it certainly has its drawbacks, you’ll probably be surprised to find that T4 medications work quite well for many people provided they are used correctly.
One of the biggest problems with the generic levothyroxine medication that you take by mouth is that your body . has a hard time absorbing and utilizing the medication
So even if it COULD be working for you it may not because it’s not actually being absorbed by your intestinal tract.
This problem can basically be bypassed by using levothyroxine injections which should have a more prominent place in the treatment of hypothyroidism for certain patients.
And that’s exactly what we are going to discuss…
Who should use levothyroxine injections, how they differ from oral levothyroxine medications, and why they may actually be a great solution for many thyroid patients.

Levothyroxine Injections as a form of thyroid medication
The idea of levothyroxine injections may sound novel but they have been around for quite a while.
Typically, levothyroxine injections are only used to treat a life-threatening condition known as myxedem (1). a coma
This condition rarely happens in the United States but it does happen in other countries.
Myxedema coma only occurs if you have hypothyroidism and don’t take your medication for several months.
Thyroid hormone is a required hormone (not optional) and if you go without it for a long length of time the consequence is coma and potentially death if not treated.
Obviously, people in a coma are not able to swallow pills so they are given levothyroxine injections (or IV thyroid hormone) to bring them out of the coma.
And so levothyroxine injections have typically only been used for this purpose.
But here I want to make the argument that levothyroxine injections have a place in the standard care of hypothyroidism.
I’m talking about you (the person reading this article), who is not in a myxedema coma, but instead is struggling with the persi despite taking medications like levothyroxine. stent symptoms of hypothyroidism
Levothyroxine has a place in restoring thyroid function to people like YOU.
I’ve personally only used levothyroxine on a handful of patients so far but the results have always been very good.
The medication seems to take effect much faster than oral medication and it seems to be far more effective at the same dose compared to oral medication.
Oral Levothyroxine vs. Levothyroxine Injection
Is oral levothyroxine really that much different than levothyroxine injections?
Aren’t they the same medication?
Well, they are obviously the same medication but how you take it makes ALL of the difference.
We have to face the facts.
Thyroid medication, in general, just isn’t well absorbed.
This is why there are so many rules about. how and when you should take your thyroid medication
On the extreme end, your pharmacist or doctor (if they tell you at all) will suggest that you take
Why do you think they make these recommendations?
Because we have all sorts of medical research and data that show that basically anything you put into your mouth at the same time as your thyroid medication will seriously impact its absorption in the intestinal tract.
Food, coffee, liquids, juices, medic. ations, supplements, and the list goes on
All of these can and do have a negative impact on how much thyroid hormone actually makes it into your body.
Before your oral thyroid medication makes it into your bloodstream it must first pass through the intestinal tract where its absorption can be delayed or blocked.
Then once it is absorbed it must pass through your liver where it can be metabolized even further which reduces the total dose that makes it to your heart.
Your heart then pumps it through your arteries to your cells which must convert it before they can use it.
Each step can be blocked or slowed down starting from the very beginning.
So it’s no wonder that so many thyroid patients struggle to feel well despite taking their medication!
What’s so different about levothyroxine injections?
These injections bypass two very important steps listed above.
First, they bypass the intestinal tract and second, they bypass the initial metabolism by your liver.
If you inject levothyroxine directly into your subcutaneous tissue, fat cells, or muscle cells, the hormone gets STRAIGHT into your cells where it can start working right away.
Whatever hormone doesn’t make it into your cells will get picked up by the lymph system (which dumps it back into your veins) or get circulated through your capillaries back to your bloodstream.
Either way, levothyroxine injections provide a quick way to get thyroid hormone directly into your body while bypassing certain areas that thyroid patients struggle with.
And bypassing these things can make ALL of the difference.
Tirosint is much better absorbed even though it contains the exact same ingredients.
And many patients report an immediate improvement when switching from levothyroxine to Tirosint.
This effect is compounded with levothyroxine injections because you still get to skip the oral absorption component.
Another example of the beneficial effects of injections over oral preparations can be seen in the case of B12 i. njections/shots
Oral B12 supplements are great because many hyp. othyroid patients suffer from B12 deficiency
But I’ve seen numerous cases of patients who light up when they receive B12 injections/shots even if they are currently using oral B12.
This is why I love B12 injections so much for thyroid patients.
I can even see a place for levothyroxine injections to treat fibromyalgia and chronic muscular pain syndromes that certain thyroid patients face.
Persistent hypothyroidism is KNOWN to cause a fibromyalgia-like syndrome as well as chronic pain due to its impact on muscular tissue.
I normally treat these issues with T3 thyroid hormone (to bypass thyroid conversion) but it would be highly likely that levothyroxine injections could do a better job by directly injecting small amounts of thyroid hormone into sore muscles.
Who should use Levothyroxine Injections?
Can anyone just jump on levothyroxine injections and call it a day?
I probably wouldn’t recommend that approach but there are a number of groups of patients who should definitely consider using them.
Also, remember that just because you use levothyroxine injections doesn’t mean you have to stay on them forever.
In the past, I’ve used these injections in certain patients to help them get control of their symptoms as they transition to oral medications (but these oral medications are always a combination of T3 and T4, not just T4).
With this in mind, here are the people who would do well on levothyroxine injections:
- Those with extreme intestinal issues – including conditions that cause malabsorption, irritable bowel syndromes, inflammatory bowel disease, SIBO/SIFO, and other conditions that disrupt the gut microbiome and impact absorption of nutrients/medications.
- Those who have had gastric bypass or other intestinal surgeries – These surgeries often cause permanent or temporary GI issues and malabsorption syndromes (2). In addition, almost all of these patients had thyroid conditions before their surgery due to their weight.
- Those who have failed standard thyroid medications of all types – If you are someone who just hasn’t responded well to thyroid medications in general then you would be a candidate.
- Those with persistent symptoms of hypothyroidism despite taking thyroid medication daily – Sometimes the TSH can respond to your thyroid medication but your symptoms remain or get worse despite taking thyroid medicine.
- As a simple test to see if you are absorbing thyroid medication – These injections can be used as a “test” to see if your medication is actually working or to gauge just how much your intestinal tract is playing a role. 2-4 weeks of levothyroxine is enough to tell.
- Those with mucin accumulation (3) in the skin which doesn’t respond to oral thyroid medications.
If you fit into any of the above categories then levothyroxine injections could be considered for your case.
But that brings up the next question:
How do you get them?
Levothyroxine injections, like any other thyroid medication, require a prescription from your doctor.
Any doctor can write a prescription for this medication but you might have trouble getting a prescription from your run-of-the-mill conventional doctor unless they understand the nuances of thyroid medication listed here.
Standard doctors such as endocrinologists and family practice providers are conditioned to believe that levothyroxine (the oral version) is the universal treatment for hypothyroidism.
And if you continue to suffer from hypothyroid symptoms then your symptoms must be related to some other cause.
This is obviously incorrect and the very reason that my website and information exist but you should be aware of this potential problem if you are seeking these injections.
Instead, you may want to look to more knowledgeable physicians and providers who are aware of the nuances of thyroid hormone management.
You can find a list of doctors who fit this category here.
Side Effects of Levothyroxine Injections
In terms of side effects, there aren’t many that you should be worried about.
Levothyroxine (of any type) is bio-identical to your body.
This means that your medication is a replica of the hormone that your own thyroid gland would produce if it were healthy.
Taking a dose that is too high can lead to hyperthyroid symptoms and taking a dose that is too low can lead to continued hypothyroid symptoms.
This shouldn’t come as a surprise.
But levothyroxine injections do have some unique side effects that you should be aware of and these all stem from how you administer the medication and not the medication itself.
Anytime you inject anything into your body you run a small risk of infection and of bleeding.
This also applies to these injections though the risk is incredibly low if you use the right technique.
In addition, I have seen some patients who report that they get small “nodules” at the injection site which tend to fade over a few weeks.
Other patients have reported dark spots at the injection site which also fade over a few months.
These side effects are not serious in the sense that they will cause significant harm but you should be aware of them.
If you aren’t doing well on regular levothyroxine or any thyroid medication for that matter, then it might be worth considering the use of levothyroxine injections.
These injections are much more powerful than regular oral thyroid medications because they bypass many of the problems that these medications face.
The result is that you can get your thyroid medication straight into your body at a much faster rate which can help improve your symptoms much faster than normal.
Levothyroxine injections may also play an important role in the treatment of fibromyalgia and chronic hypothyroid muscular pain syndromes.
