Are there any side effects of thyroxine treatment?
A. No. Thyroxine is identical to the natural hormone produced by the thyroid gland and is a relatively simple chemical substance. It is really a replacement hormone treatment rather than a drug, so any side effects only occur if the dose is wrong. If too much thyroxine is given, symptoms of hyperthyroidism will occur. If not enough is given, the hypothyroid symptoms will return. Thyroxine tablets can be stored at room temperature, last a long time, and are widely available throughout the world.
