Taking propranolol (a heart medicine) with levothyroxine (a thyroid medicine) can change how your body processes thyroid hormones. This may affect how well the propranolol works. Your thyroid levels might change, but you may feel fine.

What to do: Talk to your doctor or pharmacist about taking these medicines together. They may need to check your thyroid levels or adjust your doses. Do not stop either medicine without talking to your doctor first.
