Uses for alpelisib
Alpelisib is used together with other medicines (eg, fulvestrant) to treat hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, PIK3CAmutated, advanced or metastatic (cancer that has spread) breast cancer in men and in women who have already stopped menstruating (postmenopausal). Your doctor will test for the presence of the mutation.
Alpelisib is also used to treat PIK3CA-related overgrowth spectrum (PROS). PROS is a group of rare conditions that cause body parts to grow too much or have an unusual shape.
Alpelisib interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal cells may also be affected by the medicine, other unwanted effects will also occur. Some of these may be serious and must be reported to your doctor.
Alpelisib is available only with your doctor's prescription.

Precautions while using alpelisib

It is unlikely that a postmenopausal woman may become pregnant. But, using alpelisib while you are pregnant can harm your unborn baby. If you are a woman who can bear children, your doctor may give you a pregnancy test before you start using alpelisib to make sure you are not pregnant. Use an effective form of birth control to keep from getting pregnant during treatment and for 1 week after your last dose. Male patients who have female partners should use effective birth control during treatment and for 1 week after the last dose. If you think you have become pregnant while using the medicine, tell your doctor right away.
Alpelisib may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after using alpelisib.
Alpelisib may cause serious skin reactions, including Stevens-Johnson syndrome, erythema multiforme, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS). Check with your doctor right away if you have black, tarry stools, blistering, peeling, or loosening of the skin, chest pain, chills, cough, diarrhea, itching, joint or muscle pain, painful or difficult urination, red irritated eyes, red skin lesions, often with a purple center, sore throat, sores, ulcers, or white spots in the mouth or on the lips, swollen glands, trouble breathing, unusual bleeding or bruising, or unusual tiredness or weakness with alpelisib.
Alpelisib may affect your blood sugar levels. Check with your doctor right away if you have increased thirst or increased urination. If you notice a change in the results of your urine or blood sugar tests, or if you have any questions, check with your doctor.
Alpelisib may cause swelling of the lungs (pneumonitis) or interstitial lung disease. These are life-threatening conditions and require immediate medical attention. The symptoms may be similar to the symptoms from lung cancer. Check with your doctor right away if you have new or worsening cough, fever, or trouble breathing.
Alpelisib may cause diarrhea, and in some cases it can be severe. Your doctor may give you medicine to treat diarrhea. Drink plenty of fluids to prevent dehydration. If you have any questions about this or if mild diarrhea continues, or gets worse, check with your doctor.
If you plan to have children, talk with your doctor before using alpelisib. Some men and women using alpelisib have become infertile (unable to have children).
