When should I call my doctor if I am taking Zaltrap?

The colon cancer drug Zaltrap (ziv-aflibercept) can cause serious side effects, such as severe bleeding. Call your doctor right away if you have bleeding or symptoms of internal bleeding, such as light-headedness. Zaltrap also increases the risk that wounds will heal poorly, so you should talk to your doctor if you are scheduled for any surgery (including dental surgery).

Zaltrap can elevate blood pressure; high blood pressure often has no symptoms, but call your doctor if you have a severe headache.

Let your doctor know if you have severe diarrhea, vomiting or severe abdominal pain or if you have a fever or other signs of infection. You should also call your doctor if you have any other symptoms that are worrisome or don't go away.

Tell your doctor at once if you think you may be pregnant -- Zaltrap can cause birth defects if taken during pregnancy.

Finally, if you want or need to take a new medicine (prescription or nonprescription) or dietary supplement, call your doctor. Do not start a new drug or supplement without checking with your doctor first.
