Alpelisib is commercially available as oral tablets (Piqray(R), Vijoice(R)) or oral granules (Vijoice(R)). The Vijoice(R) tablets may also be administered as an oral suspension for patients who have difficulty swallowing the whole tablets. The most appropriate dosage form of Vijoice(R) (tablets or granules) should be prescribed based on patient needs and dosage requirements.
The oral granules are single use and only for patients prescribed a 50 mg daily dose. Clinicians should not use multiple packets to achieve a prescribed dose of 125 mg or 250 mg, and should not use partial quantities of the oral granule packets to prepare a dose. The oral granules should not be used if the packet seal is broken.
The tablets should be swallowed whole; do not chew, crush, or split. Do not use tablets that are cracked, broken, or otherwise not intact. Administer orally with food.
Take at approximately the same time each day. If a dose of alpelisib is missed and cannot be taken within 9 hours of the regularly scheduled time, skip the missed dose and take the next dose at the regularly scheduled time. If a dose of alpelisib is vomited, do not take an extra dose; take the next dose at the regularly scheduled time. Store alpelisib at 20-25degreesC (excursions permitted between 15-30degreesC).

Review the full interaction monograph for more information.
| Drug Interaction | Drug Names |
|---|---|
| Alpelisib/Strong CYP3A4 Inducers SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Agents that induce the CYP3A4 isoenzyme may induce the metabolism of alpelisib.(1,2) CLINICAL EFFECTS: Concurrent use of strong CYP3A4 inducers may decrease the levels and effectiveness of alpelisib.(1,2) PREDISPOSING FACTORS: Induction effects may be more likely with regular use of the inducer for longer than 1-2 weeks. PATIENT MANAGEMENT: The manufacturer of alpelisib states the use of strong CYP3A4 inducers in patients receiving therapy with alpelisib should be avoided. Consider the use of alternative agents with less enzyme induction potential.(1,2) DISCUSSION: In a study, rifampin, a strong CYP3A4 inducer, decreased the maximum concentration (Cmax) and area-under-curve (AUC) of single-dose alpelisib (300 mg) by 38% and 57%, respectively, and of multiple doses of alpelisib (300 mg) by 59% and 74%, respectively.(1) Strong CYP3A4 inducers linked to this monograph include: apalutamide, barbiturates, carbamazepine, encorafenib, enzalutamide, fosphenytoin, ivosidenib, lumacaftor, mitotane, phenobarbital, phenytoin, primidone, rifampin, rifapentine, and St. John's wort.(3,4) |

Alpelisib may cause fetal harm if administered to pregnant females based on its mechanism of action and animal findings.
It is not known whether alpelisib is distributed into milk. Because of the potential for serious adverse reactions to alpelisib in breast-fed infants, females should be advised to discontinue breast-feeding during alpelisib therapy and for one week after discontinuance of the drug. The effects of the drug on breast-fed infants or on milk production are unknown.
No adults >=65 years of age were enrolled in the EPIK-P1 study evaluating alpelisib in patients with PROS. In the SOLAR-1 study evaluating alpelisib in patients with breast cancer, 41% of patients receiving alpelisib were 65 years of age or older, while 12% were 75 years of age or older. No overall differences in efficacy were observed between geriatric patients 65 years of age or older and younger adults; however, grade 3 or 4 hyperglycemia occurred more frequently in geriatric patients (44 versus 32%).
Experience with alpelisib in patients 75 years of age or older is insufficient to determine whether efficacy and safety of the drug in this age group are similar to those in younger adults. However, in the SOLAR-1 study, hyperglycemia (74 versus 66%) and grade 3-4 hyperglycemia (56 versus 36%) occurred more frequently in patients 75 years of age or older compared to patients younger than 75 years of age, respectively.
