Tarceva Side Effects
Cancer medications such as Tarceva are associated with significant side effects. For example, many people taking this drug experience a rash, fatigue, or diarrhea. Although not as common, serious problems may also occur, including breathing problems, peeling skin, irregular heartbeat, or decreased urination. If you develop any of these symptoms, contact your healthcare provider right away.
Just like any cancer medicine, Tarceva® (erlotinib) can cause side effects, some of which can be significant. Although not everyone who takes the medication will have problems, most people will experience some type of reaction during treatment. Talk to your healthcare provider about ways to manage any side effects you may experience.
(This article covers many, but not all, of the possible side effects with Tarceva. Your healthcare provider can discuss a more complete list with you.)
