If you have a stroke, TIA, or bleeding in your brain while taking ZONTIVITY your doctor should stop your treatment with ZONTIVITY. Follow your doctor's instructions about stopping ZONTIVITY.

Do not stop taking ZONTIVITY without talking to the doctor who prescribed it for you.

What is ZONTIVITY?

ZONTIVITY is a prescription medicine used to treat people who have
