Brand Name(s): , Piqray®
WHY is this medicine prescribed?
Alpelisib 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 women who have already gone through menopause (''change of life,'' end of menstrual periods) or in men, whose cancer got worse during or after certain other treatments. Alpelisib is in a class of medications called kinase inhibitors. It works by blocking the signals that cause cancer cells to multiply. This helps to stop the spread of cancer cells.
Are there OTHER USES for this medicine?
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
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 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.

What should I know about STORAGE and DISPOSAL of this medication?
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]
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 ([WEB]) for more information if you do not have access to a take-back program.
What should I do in case of OVERDOSE?
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at [WEB]. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
Symptoms of overdose may include:
- lack of energy
- increased thirst and appetite
- dry mouth
- urinating more often or larger amounts
What OTHER INFORMATION should I know?
Keep all appointments with your doctor and the laboratory. Your doctor will order a lab test before you begin your treatment to see whether your cancer can be treated with alpelisib. Your doctor will also order certain lab tests before and during your treatment to check your body's response to alpelisib.
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.
