It’s a special medicine used for breast cancer that’s spread to the brain in patients who have HER2-positive cancer. This drug is one of those HER2 inhibitors. They keep cancer cells from sending out signals that make them grow.
They have it in two strengths: 50 mg and 150 mg in tablets with a coating. For grown-ups, they usually say to take 300 mg twice a day on the full stomach. You get a bottle with 60 of these tablets, which lasts for about 10 days at the recommended dose.
The whole treatment plan is meant to help with symptoms and slow down the cancer’s growth, especially if it’s moved to the brain.
