Acalabrutinib is used to treat people with mantle cell lymphoma (MCL; a fast-growing cancer that begins in the cells of the immune system) who have already been treated with at least one other chemotherapy medication. Acalabrutinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells.
Acalabrutinib comes as a capsule to take by mouth. It is usually taken with or without food every 12 hours (twice a day) for as long as your doctor recommends that you receive treatment. Take acalabrutinib at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take acalabrutinib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the capsules whole with water; do not open, chew, or break them.
Your doctor may temporarily or permanently stop your treatment or decrease your dose of acalabrutinib depending on the side effects that you experience. Be sure to talk to your doctor about how you are feeling during your treatment. Do not stop taking acalabrutinib without talking to your doctor.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site
