Alpelisib

(al" pe lis' ib)

Brand Name(s): Piqray®, Vijoice®

WHY is this medicine prescribed?

Alpelisib (Piqray) is used in combination with fulvestrant (Faslodex) to treat a certain type of breast cancer that has spread to nearby tissues or other parts of the body in adults whose cancer got worse during or after certain other treatments. Alpelisib (Vijoice) is used to treat adults and children 2 years of age or older who have certain types of PIK3CA Related Overgrowth Spectrum (PROS; a genetic condition that causes overgrowth and abnormalities in certain body tissues). Alpelisib is in a class of medications called kinase inhibitors. It works to treat cancer by blocking the signals that cause cancer cells to multiply, which helps to stop the spread of cancer cells. It works to treast PROS by blocking the signals that cause overgrowth and abnormalities in certain body tissues, which reduces the size of the overgrowths and improves symptoms.

HOW should this medicine be used?

Alpelisib comes as a tablet to take by mouth. It is usually taken with food once a day for as long as your doctor recommends treatment. Take alpelisib at around the same time 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 alpelisib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the tablets whole; do not split, chew, or crush them. Do not take a tablet that is broken, cracked, or is damaged.

If you are taking alpelisib (Vijoice) for PROS and are unable to swallow the tablets whole, you may dissolve them in water. Place the tablet(s) into a drinking glass that contains 2 to 4 ounces (60 to 120 mL) of water. Wait 5 minutes and then crush the tablets and stir the mixture with a spoon. Drink the mixture immediately. Add another 2 to 3 tablespoons of water to the glass and stir with the same spoon to rinse out any particles that are still in the glass. Drink all of this mixture to be sure that you receive all of the medication and repeat if necessary.

If you vomit after taking alpelisib, do not take another dose. Continue your regular dosing schedule.

Your doctor may decrease your dose of alpelisib, treat you with other medications, or interrupt or stop your treatment if you experience certain side effects. Be sure to tell your doctor how you are feeling during your treatment with alpelisib.
