Use of oral thyroid hormone drug products is not recommended to treat myxedema coma. Administer thyroid hormone products formulated for intravenous administration to treat myxedema coma. Concurrent use of sympathomimetics and CYTOMEL may increase the effects of sympathomimetics or thyroid hormone. Thyroid hormones may increase the risk of coronary insufficiency when sympathomimetic agents are administered to patients with coronary artery disease.

Myxedematous patients are very sensitive to thyroid; dosage should be started at a very low level and increased gradually. The higher affinity of levothyroxine (T4 ) for both thyroid-binding globulin and thyroid-binding prealbumin as compared to triiodothyronine (T3 ) partially explains the higher serum levels and longer half-life of the former hormone. Both protein-bound hormones exist in reverse equilibrium with minute amounts of free hormone, the latter accounting for the metabolic activity. Certain medications can decrease the absorption of liothyronine.

  • Probably the biggest potential con is that most conventional doctors may not be familiar or experienced with adding a T3 medication to a T4-only prescription (or switching to a T3-only medication).
  • It is the low levels of T3 and T4 that signal the release of thyroid stimulating hormone (TSH).
  • Ask your healthcare professional how you should dispose of any medicine you do not use.
  • There is no well-documented evidence from the literature, however, of true allergic or idiosyncratic reactions to thyroid hormone.

Once you get to the 100 mcg + range, you put yourself at a much higher risk of side effects like Tachycardia, muscle loss, anxiety, and feeling weak. Personally, I never go above 50 mcg because T3 can be very catabolic at higher dosages, as it doesn’t discriminate between muscle and stored fat, so the higher your T3 dose is, the more muscle it will rip off your body. The standard starting dosage for treating Hypothyroidism is typically much lower (as low as 5-10 mcg per day), and may be titrated up based on your doctor’s recommendation. T3 is a drug that is prescribed to those with hypothyroidism, but it is commonly used by bodybuilders and recreational lifters who want to reach a level of body fat that would be difficult to achieve without drug assistance. I have spoken with several individuals who have had major issues with fat loss, and having a weak metabolism who actually were walking around for years with an undiagnosed Thyroid deficiency (hypothyroidism).

The usual starting dose of liothyronine for treating hypothyroidism is 5 to 25 mcg per day. The dose then is adjusted based on the patient’s response and the blood levels of thyroid hormone. Optimal liothyronine doses are different for each patient and vary depending on the patient’s age, weight, symptoms, blood levels of thyroid hormone and underlying conditions such as heart disease.
