The most common adverse drug reactions to emtricitabine and tenofovir disoproxil fumarate (incidence ≥ 10%) were diarrhea, nausea, fatigue, headache, dizziness, depression, insomnia, abnormal dreams, and rash.
- Complera should not be used with drugs where significant decreases in rilpivirine plasma concentrations may occur ( See CONTRAINDICATIONS).
- Complera is a complete regimen for the treatment of HIV-1 infection; therefore Complera should not be administered with other antiretroviral medications for the treatment of HIV-1 infection.
- Drugs inducing or inhibiting CYP3A enzymes: 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 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 and drugs that inhibit CYP3A may result in increased plasma concentrations of rilpivirine.
- Drugs increasing gastric PH: Coadministration of rilpivirine with drugs that increase gastric pH may decrease plasma concentrations of rilpivirine and loss of virologic response and possible resistance to rilpivirine or to the class of NNRTIs.
- Drugs affecting renal function: Since emtricitabine and tenofovir are primarily eliminated by the kidneys, coadministration of Complera with drugs that reduce renal function or compete for active tubular secretion may increase serum concentrations of emtricitabine, tenofovir, and/or other renally eliminated drugs. Some examples include, but are not limited to, acyclovir, adefovir dipivoxil, cidofovir, ganciclovir, valacyclovir and valganciclovir.
- QT prolonging drugs: There is limited information available on the potential for a pharmacodynamic interaction between rilpivirine and drugs that prolong the QTc interval of the electrocardiogram. In a study of healthy subjects, supratherapeutic doses of rilpivirine (75 mg once daily and 300 mg once daily) have been shown to prolong the QTc interval of the electrocardiogram. Complera should be used with caution when coadministered with a drug with a known risk of Torsade de Pointes.
DOSAGE AND ADMINISTRATION
Adults: The recommended dose of Complera is one tablet taken orally once daily with a meal.Renal Impairment: Because Complera is a fixed-dose combination, it should not be prescribed for patients requiring dose adjustment such as those with moderate or severe renal impairment (creatinine clearance below 50 mL per minute). INDICATION Complera is indicated for use as a complete regimen for the treatment of HIV-1 infection in antiretroviral treatment-naïve adults. This indication is based on Week 48 safety and efficacy analyses from 2 randomized, double-blind, active controlled, Phase 3 trials in treatment-naïve subjects comparing rilpivirine to efavirenz.
