The Dark Side of Polivy: Understanding the Most Frequent Adverse Reactions

Polivy, also known as tucatinib, is a medication used to treat HER2-positive breast cancer. While it has shown promise in clinical trials, like any other medication, it can cause adverse reactions in some patients. In this article, we'll delve into the most frequent polivy-related adverse reactions and what you need to know.

What are Adverse Reactions?

Before we dive into the specifics of polivy-related adverse reactions, let's define what we mean by the term. Adverse reactions, also known as side effects, are unintended effects of a medication that can range from mild to severe.
