Brand names: EDURANT, EDURANT PED
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. A few cases of hepatotoxicity have occurred in patients with no pre-existing hepatic disease. Monitor liver function tests before and during treatment with EDURANT or EDURANT PED in patients with underlying hepatic disease, such as hepatitis B or C virus co-infection, or marked elevations in transaminase. Also consider monitoring liver functions tests in patients without pre-existing hepatic dysfunction or other risk factors. ( 5.2 ) Depressive Disorders: Severe depressive disorders have been reported. Immediate medical evaluation is recommended for severe depressive disorders. ( 5.3 ) Patients may develop immune reconstitution syndrome. ( 5.5 ) 5.1 Skin and Hypersensitivity Reactions Severe skin and hypersensitivity reactions have been reported during the postmarketing experience, including cases of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), with rilpivirine-containing regimens. While some skin reactions were accompanied by constitutional symptoms such as fever, other skin reactions were associated with organ dysfunctions, including elevations in hepatic serum biochemistries. During the Phase 3 clinical trials, treatment-related rashes with at least Grade 2 severity were reported in 3% of subjects receiving EDURANT. No Grade 4 rash was reported. Overall, most rashes were Grade 1 or 2 and occurred in the first four to six weeks of therapy [see Adverse Reactions (6.1 and 6.2) ] . Discontinue EDURANT or EDURANT PED immediately if signs or symptoms of severe skin or hypersensitivity reactions develop, including but not limited to, severe rash or rash accompanied by fever, blisters, mucosal involvement, conjunctivitis, facial edema, angioedema, hepatitis or eosinophilia. Clinical status including laboratory parameters should be monitored and appropriate therapy should be initiated. 5.2 Hepatotoxicity Hepatic adverse events have been reported in patients receiving a rilpivirine-containing regimen. Patients with underlying hepatitis B or C virus infection, or marked elevations in transaminases prior to treatment may be at increased risk for worsening or development of transaminase elevations with use of EDURANT or EDURANT PED. A few cases of hepatic toxicity have been reported in adult patients receiving a rilpivirine-containing regimen who had no pre-existing hepatic disease or other identifiable risk factors. Appropriate laboratory testing prior to initiating therapy and monitoring for hepatotoxicity during therapy with EDURANT or EDURANT PED is recommended in patients with underlying hepatic disease such as hepatitis B or C virus infection, or in patients with marked elevations in transaminases prior to treatment initiation. Liver enzyme monitoring should also be considered for patients without pre-existing hepatic dysfunction or other risk factors. 5.3 Depressive Disorders The adverse reaction depressive disorders (depressed mood, depression, dysphoria, major depression, mood altered, negative thoughts, suicide attempt, suicidal ideation) has been reported with EDURANT. Patients with severe depressive symptoms should seek immediate medical evaluation to assess the possibility that the symptoms are related to EDURANT or EDURANT PED, and if so, to determine whether the risks of continued therapy outweigh the benefits. During the Phase 3 trials in adults (N=1368) through 96 weeks, the incidence of depressive disorders (regardless of causality, severity) reported among EDURANT (n=686) or efavirenz (n=682) was 9% and 8%, respectively. Most events were mild or moderate in severity. The incidence of Grade 3 and 4 depressive disorders (regardless of causality) was 1% for both EDURANT and efavirenz. The incidence of discontinuation due to depressive disorders among EDURANT or efavirenz was 1% in each arm. Suicidal ideation was reported in 4 subjects in each arm while suicide attempt was reported in 2 subjects in the EDURANT arm. During the Phase 2 trial in pediatric subjects 12 to less than 18 years of age (N=36) receiving EDURANT through 48 weeks, the incidence of depressive disorders (regardless of causality, severity) was 19.4% (7/36). Most events were mild or moderate in severity. The incidence of Grade 3 and 4 depressive disorders (regardless of causality) was 5.6% (2/36). None of the subjects discontinued due to depressive disorders. Suicidal ideation and suicide attempt were reported in 1 subject. 5.4 Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions The concomitant use of EDURANT or EDURANT PED and other drugs may result in potentially significant drug interactions, some of which may lead to [see Dosage and Administration (2.7) , Contraindications (4) , and Drug Interactions (7) ] : Loss of therapeutic effect of EDURANT or EDURANT PED and possible development of resistance. In healthy subjects, 75 mg once daily and 300 mg once daily (3 times and 12 times the dose in EDURANT) have been shown to prolong the QTc interval of the electrocardiogram. Consider alternatives to EDURANT or EDURANT PED when coadministered with a drug that is known to have a risk of torsade de pointes [see Drug Interactions (7) and Clinical Pharmacology (12.2) ] . See Table 6 for steps to prevent or manage these possible and known significant drug interactions, including dosing recommendations. Consider the potential for drug interactions prior to and during EDURANT or EDURANT PED therapy and review concomitant medications during therapy. 5.5 Immune Reconstitution Syndrome Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy, including EDURANT. During the initial phase of combination antiretroviral treatment, patients whose immune system responds may develop an inflammatory response to indolent or residual opportunistic infections (such as Mycobacterium avium infection, cytomegalovirus, Pneumocystis jirovecii pneumonia or tuberculosis), which may necessitate further evaluation and treatment. Autoimmune disorders (such as Graves' disease, polymyositis, Guillain-Barré syndrome, and autoimmune hepatitis) have also been reported to occur in the setting of immune reconstitution; however, the time to onset is more variable, and can occur many months after initiation of treatment. 5.6 Different Formulations Are Not Substitutable EDURANT and EDURANT PED have differing pharmacokinetic profiles and are not substitutable on a milligram-per-milligram basis. A difference in bioavailability between 1 × 25 mg film-coated tablet and 10 × 2.5 mg tablets for oral suspension was observed; therefore, they are not substitutable [see Clinical Pharmacology (12.3) ]. When a pediatric patient weighs 25 kg or greater, they must switch from EDURANT PED tablets for oral suspension to one 25 mg EDURANT tablet daily [see Dosage and Administration (2.3) ]. Incorrect dosing of a given formulation may result in underdosing and loss of therapeutic effect and possible development of resistance or possible clinically significant adverse reactions from greater exposure to rilpivirine.
Contraindications
4 CONTRAINDICATIONS EDURANT and EDURANT PED 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 EDURANT or EDURANT PED or to the class of NNRTIs [see Drug Interactions (7) and Clinical Pharmacology (12.3) ] . Table 2: Drugs That are Contraindicated with EDURANT and EDURANT PED Drug Class Contraindicated Drugs in Class Clinical Comment Anticonvulsants Carbamazepine Oxcarbazepine Phenobarbital Phenytoin Potential for significant decreases in rilpivirine plasma concentrations due to CYP3A enzyme induction, which may result in loss of virologic response. Antimycobacterials Rifampin Rifapentine Glucocorticoid (systemic) Dexamethasone (more than a single-dose treatment) Herbal Products St. John's wort ( Hypericum perforatum ) Proton Pump Inhibitors e.g., Esomeprazole Lansoprazole Omeprazole Pantoprazole Rabeprazole Potential for significant decreases in rilpivirine plasma concentrations due to gastric pH increase, which may result in loss of virologic response. Coadministration of EDURANT or EDURANT PED is contraindicated with drugs where significant decreases in rilpivirine plasma concentrations may occur, which may result in loss of virologic response and possible resistance and cross-resistance.

Overdose
10 OVERDOSAGE There is no specific antidote for overdose with EDURANT or EDURANT PED. Human experience of overdose with EDURANT or EDURANT PED is limited. Treatment of overdose with EDURANT or EDURANT PED consists of general supportive measures including monitoring of vital signs and ECG (QT interval) as well as observation of the clinical status of the patient. It is advisable to contact a poison control center to obtain the latest recommendations for the management of an overdose. Since rilpivirine is highly bound to plasma protein, dialysis is unlikely to result in significant removal of the active substance.
Drug 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 EDURANT or EDURANT PED 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 EDURANT or EDURANT PED and drugs that inhibit CYP3A may result in increased plasma concentrations of rilpivirine. Coadministration of EDURANT or EDURANT PED 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. EDURANT or EDURANT PED at the recommended doses are not likely to have a clinically relevant effect on the exposure of drugs metabolized by CYP enzymes. Table 6 shows the established and other potentially significant drug interactions based on which alterations in dose or regimen of EDURANT or EDURANT PED and/or coadministered drug may be recommended. Drugs that are not recommended for coadministration with EDURANT or EDURANT PED are also included in Table 6 [see Dosage and Administration (2) , Contraindications (4) , and Clinical Pharmacology (12.3) ]. Table 6: Established and Other Potentially Significant Drug Interactions: Alterations in Dose or Regimen May Be Recommended Based on Drug Interaction Studies or Predicted Interaction [see Clinical Pharmacology (12.3) ] Concomitant Drug Class: Drug Name Effect on Concentration of Rilpivirine or Concomitant Drug Clinical Comment ↑=increase, ↓=decrease, ↔=no change Antacids: antacids (e.g., aluminum or magnesium hydroxide, calcium carbonate) ↔ rilpivirine (antacids taken at least 2 hours before or at least 4 hours after rilpivirine) The combination of EDURANT or EDURANT PED and antacids should be used with caution as coadministration may cause significant decreases in rilpivirine plasma concentrations (increase in gastric pH). Antacids should only be administered either at least 2 hours before or at least 4 hours after EDURANT or EDURANT PED. ↓ rilpivirine (concomitant intake) Anticonvulsants: carbamazepine oxcarbazepine phenobarbital phenytoin ↓ rilpivirine Coadministration is contraindicated with EDURANT or EDURANT PED [see Contraindications (4) ] . Antimycobacterials: rifampin rifapentine ↓ rilpivirine Coadministration is contraindicated with EDURANT or EDURANT PED [see Contraindications (4) ] . Antimycobacterials: rifabutin The interaction between EDURANT and the drug was evaluated in a clinical study. All other drug-drug interactions shown are predicted. ↓ rilpivirine Concomitant use of EDURANT with rifabutin may cause a decrease in the plasma concentrations of rilpivirine (induction of CYP3A enzymes). Throughout coadministration of EDURANT with rifabutin, the EDURANT dose should be increased from 25 mg once daily to 50 mg once daily. When rifabutin coadministration is stopped, the EDURANT dose should be decreased to 25 mg once daily. Azole Antifungal Agents: fluconazole itraconazole ketoconazole This interaction study has been performed with a dose higher than the recommended dose for EDURANT assessing the maximal effect on the coadministered drug. The dosing recommendation is applicable to the recommended doses of EDURANT once daily. posaconazole voriconazole ↑ rilpivirine ↓ ketoconazole Concomitant use of EDURANT or EDURANT PED with azole antifungal agents may cause an increase in the plasma concentrations of rilpivirine (inhibition of CYP3A enzymes). No rilpivirine dose adjustment is required when EDURANT or EDURANT PED is coadministered with azole antifungal agents. Clinically monitor for breakthrough fungal infections when azole antifungals are coadministered with EDURANT or EDURANT PED. Glucocorticoid (systemic): dexamethasone (more than a single-dose treatment) ↓ rilpivirine Coadministration is contraindicated with EDURANT or EDURANT PED [see Contraindications (4) ] . H 2 -Receptor Antagonists: cimetidine famotidine nizatidine ranitidine ↔ rilpivirine (famotidine taken 12 hours before rilpivirine or 4 hours after rilpivirine) The combination of EDURANT or EDURANT PED and H 2 -receptor antagonists should be used with caution as coadministration may cause significant decreases in rilpivirine plasma concentrations (increase in gastric pH). H 2 -receptor antagonists should only be administered at least 12 hours before or at least 4 hours after EDURANT or EDURANT PED. ↓ rilpivirine (famotidine taken 2 hours before rilpivirine) Herbal Products: St. John's wort ( Hypericum perforatum ) ↓ rilpivirine Coadministration is contraindicated with EDURANT or EDURANT PED [see Contraindications (4) ] . HIV-Antiviral Agents: Non-nucleoside Reverse Transcriptase Inhibitors (NNRTIs) NNRTI (delavirdine) ↑ rilpivirine ↔ delavirdine It is not recommended to coadminister EDURANT or EDURANT PED with delavirdine and other NNRTIs. Other NNRTIs (efavirenz, etravirine, nevirapine) ↓ rilpivirine ↔ other NNRTIs HIV-Antiviral Agents: Nucleoside Reverse Transcriptase Inhibitors (NRTIs) didanosine ↔ rilpivirine ↔ didanosine No dose adjustment is required when EDURANT or EDURANT PED is coadministered with didanosine. Didanosine is to be administered on an empty stomach and at least two hours before or at least four hours after EDURANT or EDURANT PED (which should be administered with a meal). HIV-Antiviral Agents: Protease Inhibitors (PIs)-Boosted (i.e., with coadministration of low-dose ritonavir) or Unboosted (i.e., without coadministration of low-dose ritonavir) darunavir/ritonavir ↑ rilpivirine ↔ boosted darunavir Concomitant use of EDURANT or EDURANT PED with darunavir/ritonavir may cause an increase in the plasma concentrations of rilpivirine (inhibition of CYP3A enzymes). No dose adjustment is required when EDURANT or EDURANT PED is coadministered with darunavir/ritonavir. Lopinavir/ritonavir ↑ rilpivirine ↔ boosted lopinavir Concomitant use of EDURANT or EDURANT PED with lopinavir/ritonavir may cause an increase in the plasma concentrations of rilpivirine (inhibition of CYP3A enzymes). No dose adjustment is required when EDURANT or EDURANT PED is coadministered with lopinavir/ritonavir. Other boosted PIs (atazanavir/ritonavir, fosamprenavir/ritonavir, saquinavir/ritonavir, tipranavir/ritonavir) ↑ rilpivirine ↔ boosted PI Concomitant use of EDURANT or EDURANT PED with boosted PIs may cause an increase in the plasma concentrations of rilpivirine (inhibition of CYP3A enzymes). EDURANT or EDURANT PED is not expected to affect the plasma concentrations of coadministered PIs. Unboosted PIs (atazanavir, fosamprenavir, indinavir, nelfinavir) ↑ rilpivirine ↔ unboosted PI Concomitant use of EDURANT or EDURANT PED with unboosted PIs may cause an increase in the plasma concentrations of rilpivirine (inhibition of CYP3A enzymes). EDURANT or EDURANT PED is not expected to affect the plasma concentrations of coadministered PIs. Macrolide or ketolide antibiotics: azithromycin clarithromycin erythromycin ↑ rilpivirine ↔ azithromycin ↔ clarithromycin ↔ erythromycin Macrolides are expected to increase concentrations of rilpivirine and are associated with a risk of Torsade de Pointes [Warnings and Precautions (5.4)]. Where possible, consider alternatives, such as azithromycin, which increases rilpivirine concentrations less than other macrolides. Narcotic Analgesics: methadone ↓ R(-) methadone ↓ S(+) methadone No dose adjustments are required when initiating coadministration of methadone with EDURANT or EDURANT PED. However, clinical monitoring is recommended as methadone maintenance therapy may need to be adjusted in some patients. Proton Pump Inhibitors: e.g., esomeprazole lansoprazole omeprazole pantoprazole rabeprazole ↓ rilpivirine Coadministration is contraindicated with EDURANT or EDURANT PED [see Contraindications (4) ] . In addition to the drugs included in Table 6, the interaction between EDURANT and the following drugs was evaluated in clinical studies and no dose adjustment is needed for either drug [see Clinical Pharmacology (12.3) ] : acetaminophen, atorvastatin, chlorzoxazone, cabotegravir, ethinylestradiol, norethindrone, raltegravir, sildenafil, simeprevir and tenofovir disoproxil fumarate. Rilpivirine did not have a clinically significant effect on the pharmacokinetics of digoxin or metformin. No clinically relevant drug-drug interaction is expected when EDURANT or EDURANT PED is coadministered with maraviroc, ribavirin or the NRTIs abacavir, emtricitabine, lamivudine, stavudine and zidovudine. Consider alternatives to EDURANT or EDURANT PED when coadministered with drugs with a known risk of torsade de pointes. ( 5.4 ) EDURANT and EDURANT PED should not be used in combination with NNRTIs. ( 4 , 7 ) Coadministration of EDURANT or EDURANT PED with drugs that induce or inhibit CYP3A may affect the plasma concentrations of rilpivirine. ( 4 , 7 ) Coadministration of EDURANT or EDURANT PED with drugs that increase gastric pH may decrease plasma concentrations of rilpivirine. ( 4 , 7 ) Refer to the Full Prescribing Information for other drugs that should not be coadministered with EDURANT or EDURANT PED and for other drugs that may require a change in dose or regimen. ( 7 ) 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, 75 mg once daily and 300 mg once daily (3 times and 12 times the dose in EDURANT) have been shown to prolong the QTc interval of the electrocardiogram [see Clinical Pharmacology (12.2) ] . Consider alternatives to EDURANT when coadministered with a drug with a known risk of torsade de pointes.
Uses
1 INDICATIONS AND USAGE EDURANT and EDURANT PED 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 2 years of age and older and weighing at least 14 kg with HIV-1 RNA less than or equal to 100,000 copies/mL. ( 1.1 ). Limitations of Use: More EDURANT 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 EDURANT treated subjects with HIV-1 RNA less than or equal to 100,000 copies/mL. ( 1.1 , 14 ) EDURANT is indicated in combination with VOCABRIA (cabotegravir), for short-term treatment of HIV-1 infection in adults and adolescents 12 years and older and weighing at least 35 kg who are virologically suppressed (HIV-1 RNA less than 50 copies/mL) on a stable regimen with no history of treatment failure and with no known or suspected resistance to either cabotegravir or rilpivirine. ( 1.2 ) 1.1 Treatment of HIV-1 in Treatment-Naïve Patients EDURANT and EDURANT PED, in combination with other antiretroviral agents, is indicated for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in antiretroviral treatment-naïve patients 2 years of age and older and weighing at least 14 kg with plasma HIV-1 RNA less than or equal to 100,000 copies/mL at the start of therapy. Limitations of Use More EDURANT 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 EDURANT treated subjects with HIV-1 RNA less than or equal to 100,000 copies/mL [see Clinical Studies (14.1) ] . 1.2 Treatment of HIV-1 in Combination with Cabotegravir EDURANT is indicated in combination with VOCABRIA (cabotegravir) for short-term treatment of HIV-1 infection in adults and adolescents 12 years and older and weighing at least 35 kg who are virologically suppressed (HIV-1 RNA less than 50 copies/mL) on a stable antiretroviral regimen with no history of treatment failure and with no known or suspected resistance to either cabotegravir or rilpivirine, for use as [see Dosage and Administration (2.6) ] : oral lead-in to assess the tolerability of rilpivirine prior to administration of rilpivirine extended-release injectable suspension, a component of CABENUVA (cabotegravir extended-release injectable suspension; rilpivirine extended-release injectable suspension). oral therapy for patients who will miss planned injection dosing with CABENUVA (cabotegravir extended-release injectable suspension; rilpivirine extended-release injectable suspension).
Dosage forms & strengths
2 DOSAGE AND ADMINISTRATION One 25 mg EDURANT tablet taken once daily with a meal for patients weighing at least 25 kg. ( 2.2 ) Pediatric patients 2 years of age and older and weighing at least 14 kg to less than 25 kg: Dosage of EDURANT PED is based on body weight. ( 2.3 ) EDURANT PED must be dispersed in drinking water and taken with a meal. ( 2.4 ) Do not substitute EDURANT 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 EDURANT 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 25 kg is one 25 mg tablet once daily taken orally with a meal. ( 2.5 , 12.3 ) Rifabutin coadministration: Take two 25 mg tablets of EDURANT once daily with a meal for the duration of the rifabutin coadministration. ( 2.7 ) 2.1 Overview of Different Dosage Forms EDURANT is available in two dosage forms: EDURANT 25 mg film-coated tablets for adults and pediatric patients weighing at least 25 kg. EDURANT PED 2.5 mg tablets for oral suspension should only be given to pediatric patients weighing at least 14 kg to less than 25 kg [see Dosage and Administration (2.3) ] . Do not substitute EDURANT tablets and EDURANT PED tablets for oral suspension on a milligram-per-milligram basis due to differing pharmacokinetic profiles. A difference in bioavailability between 1 × 25 mg film-coated tablet and 10 × 2.5 mg tablets for oral suspension was observed; therefore, they are NOT substitutable [see Warnings and Precautions (5.6) and Clinical Pharmacology (12.3) ]. Take EDURANT and EDURANT PED once daily with a meal in combination with other antiretrovirals [see Clinical Pharmacology (12.3) ]. 2.2 Recommended Dosage in Treatment-Naïve Adult Patients The recommended dosage of EDURANT in adult patients is one 25 mg tablet taken orally once daily with a meal [see Use in Specific Populations (8.1) and Clinical Pharmacology (12.3) ] . 2.3 Recommended Dosage in Treatment-Naïve Pediatric Patients 2 Years of Age and Older and Weighing at least 14 kg The recommended dosage of EDURANT and EDURANT PED in pediatric patients 2 years of age and older and weighing at least 14 kg is based on body weight (see Table 1 ). Both EDURANT and EDURANT PED should be taken orally once daily with a meal [see Use in Specific Populations (8.4) and Clinical Pharmacology (12.3) ] . Table 1: Recommended Dosage of EDURANT and EDURANT PED for Pediatric Patients Body Weight (kg) EDURANT 25 mg Tablets EDURANT PED 2.5 mg Tablets for Oral Suspension Total Daily Dose 14 kg to less than 20 kg Not recommended 5 tablets once daily 12.5 mg EDURANT PED once daily 20 kg to less than 25 kg Not recommended 6 tablets once daily 15 mg EDURANT PED once daily Greater than or equal to 25 kg 1 tablet once daily Not recommended 25 mg EDURANT once daily 2.4 Preparation and Administration Instructions for EDURANT PED Only Advise patients or caregivers of patients taking EDURANT PED to refer to the Instructions for Use to properly prepare and take the medication. EDURANT PED must be dispersed in drinking water and taken immediately with a meal. If not taken immediately, then the oral suspension should be discarded, and a new dose of medicine should be prepared. The patient should not chew or swallow EDURANT PED whole. The following instructions should be followed: Place the tablets for oral suspension in a cup, add 5 mL (1 teaspoon) of drinking water at room temperature. Do not crush the tablets. Swirl the cup carefully for 1–2 minutes to disperse the tablets. The oral suspension will start to look cloudy. Take all the prepared oral suspension immediately or to aid in administration, the oral suspension can be further diluted with 5 mL (1 teaspoon) of drinking water, milk, orange juice or applesauce. Swirl and take all the medicine immediately. A spoon can be used if needed. Make sure the entire dose is taken and no medicine is left in the cup. If required, add another 5 mL (1 teaspoon) of drinking water (or alternative beverage or soft food), swirl and drink immediately. 2.5 Recommended Dosage During Pregnancy For pregnant patients who are already on a stable EDURANT 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 at least 25 kg is one 25 mg tablet once daily taken orally with a meal. Refer to Table 1 for dosing recommendations for pediatric patients [see Dosage and Administration (2.2 , 2.3) ]. Lower exposures of rilpivirine were observed during pregnancy, therefore viral load should be monitored closely [see Use in Specific Populations (8.1) and Clinical Pharmacology (12.3) ] . 2.6 Recommended Dosage in Combination with Cabotegravir in Adults and Adolescents 12 Years of Age and Older and Weighing at least 35 kg Consult the prescribing information for CABENUVA (cabotegravir extended-release injectable suspension; rilpivirine extended-release injectable suspension) before initiating EDURANT to ensure therapy with CABENUVA is appropriate. Oral Lead-In Dosing to Assess Tolerability of Rilpivirine Oral lead-in should be used for approximately 1 month (at least 28 days) to assess the tolerability of rilpivirine prior to the initiation of CABENUVA. The recommended oral daily dose is one 25 mg tablet of EDURANT (rilpivirine) in combination with one 30 mg tablet of VOCABRIA (cabotegravir). Take EDURANT with VOCABRIA (cabotegravir) orally once daily at approximately the same time each day with a meal [see Clinical Pharmacology (12.3) ]. Because EDURANT is indicated in combination with VOCABRIA (cabotegravir), the prescribing information for VOCABRIA (cabotegravir) tablets should also be consulted. The last oral dose should be taken on the same day injections with CABENUVA are started. Oral Dosing to Replace Planned Missed Injections of CABENUVA Planned Missed Injections for Patients on Monthly Dosing Schedule If a patient plans to miss a scheduled monthly injection of CABENUVA by more than 7 days, take daily oral therapy for up to 2 months to replace missed injection visits. The recommended oral daily dose is one 25 mg tablet of EDURANT and one 30 mg tablet of VOCABRIA (cabotegravir). Take EDURANT with VOCABRIA (cabotegravir) at approximately the same time each day with a meal. The first dose of oral therapy should be initiated at approximately the same time as the planned missed injection and continued until the day injection dosing is restarted. For oral therapy with EDURANT and VOCABRIA of durations greater than 2 months, an alternative oral regimen is recommended, which may include EDURANT. See full prescribing information for CABENUVA to resume monthly injection dosing. Planned Missed Injections for Patients on Every-2-Month Dosing Schedule If a patient plans to miss a scheduled every-2-month injection of CABENUVA by more than 7 days, take daily oral therapy for a duration of up to 2 months to replace 1 missed scheduled every-2-month injection. The recommended oral daily dose is one 25 mg tablet of EDURANT and one 30 mg tablet of VOCABRIA (cabotegravir). Take EDURANT with VOCABRIA (cabotegravir) at approximately the same time each day with a meal. The first dose of oral therapy should be initiated at approximately the same time as the planned missed injection and continued until the day injection dosing is restarted. For oral therapy with EDURANT and VOCABRIA of durations greater than 2 months, an alternative oral regimen is recommended, which may include EDURANT. See full prescribing information for CABENUVA to resume every-2-month injection dosing. 2.7 Recommended Dosage with Rifabutin Coadministration If EDURANT is coadministered with rifabutin, the EDURANT dose should be increased to 50 mg (two 25 mg tablets) once daily, taken with a meal. When rifabutin coadministration is stopped, the EDURANT dose should be decreased to 25 mg once daily, taken with a meal [see Drug Interactions (7) and Clinical Pharmacology (12.3) ]. Note that use of CABENUVA (cabotegravir extended-release injectable suspension; rilpivirine extended-release injectable suspension) with rifabutin is contraindicated. Refer to CABENUVA labeling for additional detail.
