Brigatinib : Uses, Side Effects, Interactions & More

Why is this medication prescribed?

Brigatinib is used to treat a certain type of non-small cell lung cancer (NSCLC) that has spread to other parts of the body. Brigatinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.

How should this medicine be used?

Brigatinib comes as a tablet to take by mouth. It is usually taken with or without food once a day. Take brigatinib at around the same times every day. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any parts you do not understand. Take brigatinib exactly as directed. Do not take more or less, or take it more often than prescribed by your doctor.

Swallow the tablets whole; do not chew or crush them.

If you vomit after taking brigatinib, do not take another dose. Continue with your usual dosing schedule.

Your doctor may start you on a low dose of brigatinib and increase your dose once after 7 days of treatment.

Your doctor may need to temporarily or permanently stop your treatment or decrease your dose of brigatinib or other medications that you are taking, depending on the side effects you experience during your treatment. Talk to your doctor about how you feel during your treatment. Do not stop taking brigatinib without consulting your doctor.

Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.

Your doctor may need to change the doses of your medications or monitor you closely for side effects. Many other medications can also interact with brigatinib, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
  • Tell your doctor what herbal products you are taking, especially St. John’s wort.
  • Tell your doctor if you have or have ever had high blood pressure; a slow heartbeat; diabetes or other blood sugar problems; or kidney or liver disease.
  • Tell your doctor if you are pregnant, plan to become pregnant, or plan to have a child. Brigatinib can interfere with the action of hormonal contraceptives (birth control pills, patches, rings, implants, or injections), so you should not use them as your only method of contraception during your treatment. You must use a non-hormonal method of birth control, such as a barrier method (a device that prevents sperm from entering the uterus, such as a condom or diaphragm). Ask your doctor to help you choose a method of birth control that works for you. If you are a woman, you will need to use non-hormonal contraception during your treatment and for 4 months after your final dose. If you are a man, you and your female partner must use birth control during your treatment and continue to use birth control for 3 months after your last dose. Brigatinib can harm the fetus.
  • Tell your doctor if you are breastfeeding. You should not breastfeed during your treatment with brigatinib and for 1 week after your final dose.
  • You should know that this medicine can decrease fertility in men. Talk to your doctor about the risks of taking brigatinib.

What should I know about storage and disposal of this medication?

Keep this medicine in the container it came in, tightly closed, and out of the reach of children. Store at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medicines out of the sight and reach of children, since many containers (such as those containing weekly pills and those for eye drops, creams, patches and inhalers) are not resistant to children and small children can easily open them.
