Liothyronine Side Effects

Liothyronine is a synthetic (laboratory man-made) form of thyroid hormone called triiodothyronine that is very often shortly called T3. This synthetic hormone is working the exact same way as the naturally occurring one – the body cannot “see” a difference between the natural and synthetic form of hormone. Therefore, by using Liothyronine (full name of active substance – Liothyronine Sodium and most commonly sold as brand Cytomel T3) the user is increasing the total thyroid hormone levels.

The product is used for treating hypothyroidism in most cases, but it has other uses too such as myxedema coma and others.

Liothyronine is coming in form of injection into a vein but most commonly, Liothyronine Sodium comes as pills that should be taken by mouth.

  • The compound is used in medical settings for various medical purposes as it was earlier mentioned (mostly for the treatment of hypothyroidism – the opposite of hyperthyroidism) but is also used by bodybuilders who need to lose body weight and fat.


When the compound is given under the supervision of a doctor, the patient should take it exactly as said by the doctor and report everything that you notice. However, when athletes use Liothyronine for their physique and performance enhancement, mainly for weight loss purposes they should watch out for the negative side effects.

Is quite obvious that Liothyronine is possible to offer negative side effects but as it was noticed, the side effects of Liothyronine Sodium mostly appear only from excessive doses.

This means that if you are going to have a proper use of Liothyronine, there are very low chances that you would receive any nasty side effects. If you would abuse the compound, the chances of receiving bad side effects greatly increase. In short – the higher the dosage of the product the more effective it gets, but the more and more pronounced side effects would occur.


  • That’s why is so important to start with a low dosage and then slowly increase the dosage if you would require more – this way you allow your body to get accustomed to the effects of the product and avoid nasty side effects even if they occur.

Is important to understand that Liothyronine Sodium, when administered, is just increasing the total levels of the thyroid hormones in the body. If you get side effects it means that you have too much hormones in the body and that’s why, the side effects are related to hyperthyroidism.

When you use too much Liothyronine, you get hyperthyroidism based side effects and they go as:

  • Weight loss
  • Fever
  • Headaches that can be strong
  • Insomnia and trouble sleeping
  • Anxiety
  • Low resistance to heat
  • Arrhythmias
  • Heart issues such as irregular heart beats, tachycardia or heart failure including others
  • Stomach issues
  • Body tremors or shakes (mostly hand shakes)
  • And there are various others.

Is important to keep in mind that high dosages may stress your heart and that’s why you’ve got to use the compound carefully.

Another thing that should be mentioned when talking about Liothyronine side effects is that the compound is going to suppress the production of natural thyroid hormones. Pretty much as anabolic steroids suppress testosterone.

With this being said, when you stop using Liothyronine, your body requires a while until would produce enough thyroid hormones on its own. That’s why, there’s a chance that you would get too little thyroid hormones (hypothyroidism) when you stop using the compound as you don’t get the hormones naturally.
