THYROLAR

Use this medicine only as directed by your doctor. Do not use more or less of it, and do not use it more often than your doctor ordered. Your doctor has prescribed the exact amount your body needs and if you take different amounts, you may experience symptoms of an overactive or underactive thyroid. Take it at the same time each day to make sure it always has the same effect.

If your condition is due to a lack of thyroid hormone, you may have to take this medicine for the rest of your life. It is very important that you do not stop taking this medicine without first checking with your doctor.

Dosing
