What is the most important information I should know about Tarceva?

Everyone reacts differently to treatment with Tarceva. It’s important to know the most serious and most common side effects with Tarceva.

Your healthcare provider (HCP) may lower the dose or stop treatment with Tarceva if any serious side effects occur. Contact your HCP right away if you have any of the following side effects.

What are the possible side effects of Tarceva?

Tarceva can cause serious side effects, including:

  • Lung problems (called interstitial lung disease [ILD] events). Tarceva has been shown to cause lung problems, including death. Symptoms of lung problems may include shortness of breath, cough, and fever. Tarceva may need to be stopped if you have any of these symptoms
