General

Pronunciation:
(a kal" a broo' ti nib)

Brand name:

  • Calquence®

Why Prescribed

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.

How to Use

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.

Storage Considerations

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. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

Emergency Overdose

In case of overdose, call your local poison control center at 1-800-222-1222. If the victim has collapsed or is not breathing, call local emergency services at 911.

Additional Information

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to acalabrutinib.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
