Will I have to take thyroid hormone pills for the rest of my life because I had thyroid cancer? When is the best time of day to take it? How does the drug interact with/ other medications I take?


Marcia Brose, MD, Director of Thyroid Cancer Therapeutics Program at Penn Medicine responds:

If your whole thyroid was removed you will need to take thyroid hormone pills for the rest of your life. You can ask your local pharmacist for a list of medications which interact with your thyroid hormone medications. Usually, the best time of day to take your medicine is first thing in the morning, at least an hour before breakfast.
