It’s a drug specifically for HER2-positive breast cancer with brain tumors. So, it’s like a block to the HER2 signaling. You got two types of pills for taking, a 50 mg one and a 150 mg one.
You’re usually supposed to take the 300 mg amount, twice a day, and make sure to eat while doing it. Each bottle comes with 60 of these tablets. They’re meant to be taken as 300 mg once a day or 150 mg twice a day.
The doctor will tweak the treatment if it’s not working out for you or if it feels too much.
