NOW APPROVED for early-stage HER2+ breast cancer

Asset 1

Don't be embarrassed to talk openly with your doctor or nurse and ask questions that you may feel are silly. It's okay to speak up and say when you don't understand something. You and your healthcare team are partners when it comes to your health. That means communication is key.

WHAT TO ASK TO GET THE INFORMATION YOU NEED

  • I want to make sure I take NERLYNX correctly. What’s the best way to take it?

  • Can you tell me about the side effects I should expect? What can I do to manage the most common ones?

  • How can I minimize any diarrhea I may experience?

  • If I’m tired, what can I do to help get through the day or finish tasks that are important to me?

  • What should I do if a side effect worsens or starts to concern me?

Always keep your healthcare team in the loop with how you’re feeling and what you’re thinking. Don’t just ask questions. Tell your team what’s going on. Maybe start by writing down and sharing any side effects that you experience.
