Tucatinib 300mg $120

Tucatinib is made just for treating breast cancer patients who have tumors in their brain and their cancer is HER2-positive. It works by stopping something called the HER2 signaling pathway. This pathway is really important in how breast cancer grows and spreads.

Tucatinib is in tablet form with a few different strengths—50 mg and 150 mg ones. You’re supposed to take 300 mg of it two times a day. Eating food while you take it helps it work better.

One bottle has 60 tablets, which is just right for a month’s worth of your doses. This is a pill you take, and it’s super important to take it the right way to get the best results.
