Tucatinib is a HER2 blocker. It’s mainly used for breast cancer patients who have brain tumors and HER2-positive cancer. Its job is to stop HER2 signals.
You can get it in 50 mg or 150 mg doses, and it comes in a coated pill form. The usual dose is 300 mg, twice a day, and you should take it with food. Each bottle has 60 pills.
It’s pretty convenient for keeping track of your doses. Tucatinib’s mechanism of action makes it particularly valuable for patients with breast cancer who have developed brain metastases, as it is formulated to cross the blood-brain barrier, thereby addressing the challenge of treating cancer cells in the brain. It’s really important to take your medicine like the doctor says and always have enough of it to work well.
