Uses
1 INDICATIONS AND USAGE Rilpivirine tablets are a human immunodeficiency virus type 1 (HIV-1) specific, non-nucleoside reverse transcriptase inhibitor (NNRTI) indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in treatment-naïve patients 12 years of age and older and weighing at least 35 kg with HIV-1 RNA less than or equal to 100,000 copies/mL ( 1.1 ) Limitations of Use: More rilpivirine treated subjects with HIV-1 RNA greater than 100,000 copies/mL at the start of therapy experienced virologic failure (HIV-1 RNA≥50 copies/mL) compared to rilpivirine treated subjects with HIV-1 RNA less than or equal to 100,000 copies/mL.
Dosage
2 DOSAGE AND ADMINISTRATION One 25 mg rilpivirine tablet taken once daily with a meal for patients weighing at least 35 kg. ( 2.2 ) Do not substitute rilpivirine tablets and EDURANT PED tablets for oral suspension on a milligram-per-milligram basis due to differing pharmacokinetic profiles. ( 2.1 , 5.6 ) See full prescribing information for dosing information when used in combination with cabotegravir. ( 2.6 ) For pregnant patients who are already on a stable rilpivirine regimen prior to pregnancy and who are virologically suppressed (HIV-1 RNA less than 50 copies per mL) the recommended dosage in adults and pediatric patients weighing more than 35 kg is one 25 mg tablet once daily taken orally with a meal.
Side Effects
6 ADVERSE REACTIONS The following adverse reactions are discussed below and in other sections of the labeling: Skin and Hypersensitivity Reactions [see Warnings and Precautions ( 5.1 )] Hepatotoxicity [see Warnings and Precautions ( 5.2 )] Depressive Disorders [see Warnings and Precautions ( 5.3 )] The most common adverse reactions to rilpivirine tablets (incidence >2%) of at least moderate to severe intensity (≥ Grade 2) were depressive disorders, headache, insomnia and rash.
Interactions
7 DRUG INTERACTIONS Rilpivirine is primarily metabolized by cytochrome P450 (CYP)3A, and drugs that induce or inhibit CYP3A may thus affect the clearance of rilpivirine. Coadministration of rilpivirine tablets and drugs that induce CYP3A may result in decreased plasma concentrations of rilpivirine and loss of virologic response and possible resistance to rilpivirine or to the class of NNRTIs. Coadministration of rilpivirine tablets and drugs that inhibit CYP3A may result in increased plasma concentrations of rilpivirine. Coadministration of rilpivirine tablets with drugs that increase gastric pH may result in decreased plasma concentrations of rilpivirine and loss of virologic response and possible resistance to rilpivirine or to the class of NNRTIs.
Warnings
5 WARNINGS AND PRECAUTIONS Skin and Hypersensitivity Reactions: Severe skin and hypersensitivity reactions have been reported during postmarketing experience, including cases of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), with rilpivirine-containing regimens. Immediately discontinue treatment if hypersensitivity or rash with systemic symptoms or elevations in hepatic serum biochemistries develop and closely monitor clinical status, including hepatic serum biochemistries. ( 5.1 ) Hepatotoxicity: Hepatic adverse events have been reported in patients with underlying liver disease, including hepatitis B or C virus co-infection, or in patients with elevated baseline transaminases. 4 CONTRAINDICATIONS Rilpivirine tablets are contraindicated for coadministration with the drugs in Table 2 for which significant decreases in rilpivirine plasma concentrations may occur due to CYP3A enzyme induction or gastric pH increase, which may result in loss of virologic response and possible resistance to rilpivirine tablets or to the class of NNRTIs [see Drug Interactions ( 7 ) and Clinica...
Pregnancy
8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to rilpivirine tablets during pregnancy. Healthcare providers are encouraged to register patients by calling the Antiretroviral Pregnancy Registry (APR) 1-800-258-4263. Risk Summary Available data from the APR show no difference in the overall risk of birth defects for rilpivirine compared with the background rate for major birth defects of 2.7% in the Metropolitan Atlanta Congenital Defects Program (MACDP) reference population (see Data) .
Storage
16 HOW SUPPLIED/STORAGE AND HANDLING Rilpivirine Tablets Rilpivirine 25 mg tablets are supplied as white to off-white, film-coated, round, biconvex, 6.5 mm tablets. Each tablet contains 27.5 mg of rilpivirine hydrochloride, which is equivalent to 25 mg of rilpivirine. Each tablet is debossed with "RP" on one side and "25" on the other side.
