Rilpivirine/Proton Pump Inhibitors SEVERITY LEVEL: 1-Contraindicated Drug Combination: This drug combination is contraindicated and generally should not be dispensed or administered to the same patient. MECHANISM OF ACTION: Rilpivirine requires an acidic medium for absorption. The proton pump inhibitor induced decrease in gastric pH may result in a decrease in rilpivirine absorption.(1) CLINICAL EFFECTS: Concurrent use of a proton pump inhibitor may result in decreased levels and effectiveness of rilpivirine, as well as the development of resistance.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The US manufacturer of rilpivirine states that concurrent use of proton pump inhibitors is contraindicated.(1) When substituting antacids for proton pump inhibitors in patients maintained on rilpivirine, administer the antacid at least 2 hours before or 4 hours after rilpivirine.(1) When substituting H2 antagonists for proton pump inhibitors in patients maintained on rilpivirine, administer the H2 antagonist at least 12 hours before or 4 hours after rilpivirine.(1) DISCUSSION: In a study in 16 subjects, omeprazole (20 mg daily) decreased the maximum concentration (Cmax), area-under-curve (AUC), and minimum concentration (Cmin) of rilpivirine (150 mg daily) by 40%, 40%, and 33%, respectively. The Cmax and AUC of omeprazole decreased by 14% and 14%, respectively.(1) In a study in 24 subjects, famotidine (40 mg single dose) administered 12 hours before a single dose of rilpivirine (150 mg) had no significant effect on rilpivirine Cmax or AUC.(1) In a study in 23 subjects, famotidine (40 mg single dose) administered 2 hours before a single dose of rilpivirine (150 mg) decreased the rilpivirine Cmax and AUC by 85% and 76%, respectively.(1) In a study in 24 subjects, famotidine (40 mg single dose) administered 4 hours after a single dose of rilpivirine (150 mg) increased the rilpivirine Cmax and AUC by 21% and 13%, respectively.(1)	ACIPHEX, ACIPHEX SPRINKLE, DEXILANT, DEXLANSOPRAZOLE DR, ESOMEPRAZOLE MAGNESIUM, ESOMEPRAZOLE SODIUM, KONVOMEP, LANSOPRAZOL-AMOXICIL-CLARITHRO, LANSOPRAZOLE, NAPROXEN-ESOMEPRAZOLE MAG, NEXIUM, OMECLAMOX-PAK, OMEPRAZOLE, OMEPRAZOLE-SODIUM BICARBONATE, PANTOPRAZOLE SODIUM, PANTOPRAZOLE SODIUM-0.9% NACL, PREVACID, PRILOSEC, PROTONIX, PROTONIX IV, RABEPRAZOLE SODIUM, TALICIA, VIMOVO, VOQUEZNA, VOQUEZNA DUAL PAK, VOQUEZNA TRIPLE PAK, YOSPRALA
Cobicistat-Elvitegravir/NNRTIs SEVERITY LEVEL: 1-Contraindicated Drug Combination: This drug combination is contraindicated and generally should not be dispensed or administered to the same patient. MECHANISM OF ACTION: Cobicistat inhibits CYP2D6, CYP3A4, BCRP, OATP1B1 and OATP1B3. Elvitegravir induces CYP2C9. Efavirenz may induce the metabolism of cobicistat via CYP3A4.(1) CLINICAL EFFECTS: Concurrent use of cobicistat-elvitegravir with non-nucleoside reverse transcriptase inhibitors (NNRTIs) may result in altered and/or suboptimal pharmacokinetics of cobicistat, elvitegravir, and/or the NNRTI.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The combination product containing cobicistat-elvitegravir-emtricitabine-tenofovir should not be used with non-nucleoside reverse transcriptase inhibitors.(1) DISCUSSION: Concurrent use of cobicistat-elvitegravir with non-nucleoside reverse transcriptase inhibitors may result in altered and/or suboptimal pharmacokinetics of cobicistat, elvitegravir, and/or the NNRTI.(1)	GENVOYA, STRIBILD
Dofetilide/Dolutegravir SEVERITY LEVEL: 1-Contraindicated Drug Combination: This drug combination is contraindicated and generally should not be dispensed or administered to the same patient. MECHANISM OF ACTION: Dolutegravir may inhibit the elimination of dofetilide by the renal organic cation transporter (OCT2).(1) CLINICAL EFFECTS: Concurrent use of dolutegravir may result in elevated levels of dofetilide.(1) Dofetilide has been shown to prolong the QTc interval in a dose-dependent fashion. Concurrent use with other agents that prolong the QTc interval may result in additive effects on the QTc interval which may result in potentially life-threatening cardiac arrhythmias, including torsades de pointes(TdP).(2) PREDISPOSING FACTORS: Renal impairment may increase risk for excessive QTc prolongation as dofetilide is primarily renally eliminated. To prevent increased serum levels and risk for ventricular arrhythmias, dofetilide must be dose adjusted for creatinine clearance < or = to 60 mL/min.(1) The risk of QT prolongation or torsades de pointes may be increased in patients with cardiovascular disease (e.g. heart failure, myocardial infarction, history of torsades de pointes, congenital long QT syndrome), hypokalemia, hypomagnesemia, hypocalcemia, bradycardia, female gender, or advanced age.(3) Concurrent use of more than one drug known to cause QT prolongation or higher systemic concentrations of either QT prolonging drug are additional risk factors for torsades de pointes. Factors which may increase systemic drug concentrations include rapid infusion of an intravenous dose or impaired metabolism or elimination of the drug (e.g. coadministration with an agent which inhibits its metabolism or elimination, genetic impairment in drug metabolism or elimination, and/or renal/hepatic dysfunction).(3) PATIENT MANAGEMENT: Concurrent use of dofetilide and dolutegravir is contraindicated. If dofetilide is to be discontinued, a washout of at least 2 days is recommended prior to starting dolutegravir.(1,2) If concurrent therapy is deemed medically necessary, obtain serum calcium, magnesium, and potassium levels and monitor ECG at baseline and at regular intervals. Correct any electrolyte abnormalities. Instruct patients to report any irregular heartbeat, dizziness, or fainting. DISCUSSION: Dolutegravir has been shown to inhibit OCT2 in vitro and in vivo and is expected to inhibit the excretion of dofetilide.(1)	DOFETILIDE, TIKOSYN

Review the full interaction monograph for more information.

Drug Interaction	Drug Names
Dolutegravir/Etravirine; Efavirenz; Nevirapine SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Etravirine, efavirenz, and nevirapine may induce the metabolism of dolutegravir via CYP3A4.(1,2) Efavirenz may also induce dolutegravir metabolism via UGT enzymes. CLINICAL EFFECTS: Concurrent use of etravirine, efavirenz, or nevirapine and dolutegravir may result in decreased levels of and clinical effectiveness of dolutegravir.(1,2) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The US manufacturer of dolutegravir states that dolutegravir should not be used with etravirine without atazanavir/ritonavir (ATVr), darunavir/ritonavir (DRVr), or lopinavir/ritonavir (LPVr).(1) The Canadian(3) and UK(4) manufacturers of dolutegravir state that INSTI-naive patients may use etravirine concurrently with dolutegravir at an increased dose of 50 mg twice daily. In pediatric patients, the weight-based once daily dose should be given twice daily. No dose adjustment for dolutegravir is needed when used with etravirine along with concurrent ATVr, DRVr, or LPVr.(1,3-5) When used with efavirenz, the dosage of dolutegravir should be 50 mg twice daily.(1,2) When using the combination abacavir-dolutegravir-lamivudine product, an additional 50 mg dolutegravir table should be taken 12 hours apart from the combination product.(2) Alternative combinations that do not induce metabolic inducers should be considered when possible for INSTI-experience patients with certain INSTI-associated resistance substitutions or clinically suspected INSTI resistance. In pediatric patients, increase the weight-based dose to twice daily. Refer to the current labeling for the specific dosing recommendation.(1) Although the US(1) and Canadian(3) manufacturers of dolutegravir recommend avoiding concurrent use of nevirapine, the US Department of Health and Human Services HIV guidelines recommend standard doses of dolutegravir when administered concurrently with nevirapine.(5) The UK manufacturer of dolutegravir recommends increasing the dose of dolutegravir to 50 mg twice daily when used concurrently with nevirapine.(4) DISCUSSION: In a study in 12 subjects, the administration of efavirenz with dolutegravir (50 mg daily) decreased the maximum concentration (Cmax), area-under-curve (AUC), and minimum concentration (Cmin) of dolutegravir by 39%, 57%, and 75%, respectively.(1) In a study in 16 subjects, the administration of etravirine with dolutegravir (50 mg daily) decreased the Cmax, AUC, and Cmin of dolutegravir by 52%, 71%, and 88%, respectively.(1) In a study in 9 subjects, the administration of etravirine and darunavir/ritonavir (200 mg and 600/100 mg BID) with dolutegravir (50 mg daily) decreased the Cmax, AUC, and Cmin of dolutegravir by 12%, 25%, and 37%, respectively.(1) In a study in 8 subjects, the administration of efavirenz and lopinavir/ritonavir (200 mg and 400/100 mg BID) with dolutegravir (50 mg daily) increased the Cmax, AUC, and Cmin of dolutegravir by 7%, 11%, and 28%, respectively.(1)	EFAVIRENZ, EFAVIRENZ-EMTRIC-TENOFOV DISOP, EFAVIRENZ-LAMIVU-TENOFOV DISOP, ETRAVIRINE, INTELENCE, NEVIRAPINE, NEVIRAPINE ER, SYMFI, SYMFI LO
Dolutegravir/Selected UGT1A & CYP3A4 Inducers SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Dolutegravir is metabolized by UGT1A1 and to a smaller extent by CYP3A4. Inducers of UGT1A1 and CYP3A4 may induce the metabolism of dolutegravir.(1-6) CLINICAL EFFECTS: Concurrent use of UGT1A1 and CYP3A4 inducers may result in decreased levels of and clinical effectiveness of dolutegravir.(1-6) PREDISPOSING FACTORS: Induction effects may be more likely with regular use of the inducer for longer than 1-2 weeks. PATIENT MANAGEMENT: When used with carbamazepine, fosamprenavir/ritonavir, rifampin, or tipranavir/ritonavir, the dosage of dolutegravir should be 50 mg twice daily. When using the combination abacavir-dolutegravir-lamivudine or dolutegravir-lamivudine product, an additional 50 mg dolutegravir table should be taken 12 hours apart from the combination product. In pediatric patients, increase the weight-based dose to twice daily. Refer to the current labeling for the specific dosing recommendation. Alternative combinations that do not induce metabolic inducers should be considered when possible for INSTI-experience patients with certain INSTI-associated resistance substitutions or clinically suspected INSTI resistance.(1,4-6) Recommendations for other UGT1A1 and CYP3A4 inducers differ by region. The US manufacturer of dolutegravir states that concurrent use should be avoided due to insufficient data to make dosing recommendations for concomitant use.(1,4) The Canadian and UK manufacturers of dolutegravir state that the dosage of dolutegravir should be 50 mg twice daily when used concurrently with other UGT1A1 and CYP3A4 inducers. When using the combination abacavir-dolutegravir-lamivudine product, an additional 50 mg dolutegravir table should be taken 12 hours apart from the combination product. In pediatric patients, increase the weight-based dose to twice daily. Refer to the current labeling for the specific dosing recommendation. Alternative combinations that do not induce metabolic inducers should be considered when possible for patients with certain INSTI-associated resistance substitutions or clinically suspected INSTI resistance.(5,6) DISCUSSION: In a study in 12 subjects, the administration of fosamprenavir/ritonavir (700/100 mg BID) with dolutegravir (50 mg daily) decreased the maximum concentration (Cmax), area-under-curve (AUC), and minimum concentration (Cmin) of dolutegravir by 24%, 35%, and 49%, respectively.(1) In a study in 11 subjects, the administration of rifampin (600 mg daily) with dolutegravir (50 mg BID) decreased the Cmax, AUC, and Cmin of dolutegravir by 43%, 54%, and 32%, respectively, when compared to the administration of dolutegravir (50 mg BID) alone.(1) In a study in 11 subjects, the administration of rifampin (600 mg daily) with dolutegravir (50 mg BID) increased the Cmax, AUC, and Cmin of dolutegravir by 18%, 33%, and 22%, respectively, when compared to the administration of dolutegravir (50 mg daily) alone.(1) In a study in 14 subjects, the administration of tipranavir/ritonavir (500/200 mg BID) with dolutegravir (50 mg daily) decreased the Cmax, AUC, and Cmin of dolutegravir by 46%, 59%, and 76%, respectively.(1) In a study in 16 subjects, the administration of carbamazepine (300 mg twice daily) with dolutegravir (50 mg daily) decreased the Cmax, AUC, and Cmin of dolutegravir by 33%, 49%, and 73%, respectively. (1) UGT1A1 and CYP3A4 inducers linked to this monograph include: apalutamide, barbiturates, carbamazepine, encorafenib, enzalutamide, fosamprenavir/ritonavir, fosphenytoin, ivosidenib, lorlatinib, lumacaftor, mitotane, oxcarbazepine, phenobarbital, phenytoin, primidone, rifampin, rifapentine, and tipranavir/ritonavir.(1,7)	APTIVUS, ASA-BUTALB-CAFFEINE-CODEINE, ASCOMP WITH CODEINE, BRAFTOVI, BUTALB-ACETAMINOPH-CAFF-CODEIN, BUTALBITAL, BUTALBITAL-ACETAMINOPHEN, BUTALBITAL-ACETAMINOPHEN-CAFFE, BUTALBITAL-ASPIRIN-CAFFEINE, CARBAMAZEPINE, CARBAMAZEPINE ER, CARBATROL, CEREBYX, DILANTIN, DILANTIN-125, DONNATAL, EPITOL, EQUETRO, ERLEADA, FIORICET, FIORICET WITH CODEINE, FOSAMPRENAVIR CALCIUM, FOSPHENYTOIN SODIUM, LORBRENA, LYSODREN, MITOTANE, MYSOLINE, ORKAMBI, OXCARBAZEPINE, OXCARBAZEPINE ER, OXTELLAR XR, PENTOBARBITAL SODIUM, PHENOBARBITAL, PHENOBARBITAL SODIUM, PHENOBARBITAL-BELLADONNA, PHENOBARBITAL-HYOSC-ATROP-SCOP, PHENOHYTRO, PHENYTEK, PHENYTOIN, PHENYTOIN SODIUM, PHENYTOIN SODIUM EXTENDED, PRIFTIN, PRIMIDONE, RIFADIN, RIFAMPIN, SEZABY, TEGRETOL, TEGRETOL XR, TENCON, TIBSOVO, TRILEPTAL, XTANDI
Oral Rilpivirine/Rifabutin SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Rifabutin may induce the metabolism of rilpivirine by CYP3A4.(1) CLINICAL EFFECTS: Concurrent or recent use of rifabutin may result in decreased levels and effectiveness of rilpivirine, as well as the development of resistance.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The US manufacturer of oral rilpivirine states that concurrent use of CYP3A4 inducers such as rifabutin warrants dose adjustment. When administering rifabutin with oral rilpivirine, increase the dose of rilpivirine to 50 mg once daily. When rifabutin co-administration is stopped, the rilpivirine dose should be decreased to 25 mg once daily. It may take several weeks after the discontinuation of an enzyme inducer for enzyme activity to return to normal.(1) DISCUSSION: In a study in 18 subjects, rifabutin (300 mg daily) decreased the maximum concentration (Cmax), area-under-curve (AUC), and minimum concentration (Cmin) of rilpivirine (25 mg orally daily) by 31%, 42%, and 48%, respectively.(1) A study in 18 subjects compared rilpivirine administered alone (25 mg orally daily) to coadministration with rifabutin (300 mg daily) and rilpivirine (50 mg orally daily). A significant difference was not found with the Cmax (1.43), AUC (1.16), or Cmin (0.93) of rilpivirine. (1)	RIFABUTIN, TALICIA
Dalfampridine/Cimetidine; Dolutegravir SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Cimetidine and dolutegravir inhibit the organic cation transporter 2 (OCT2). Dalfampridine is eliminated mainly via the kidneys with active renal secretion by OCT2.(1-3) CLINICAL EFFECTS: The concurrent administration of dalfampridine with an inhibitor of OCT2 may result in elevated levels of dalfampridine and signs of toxicity. Elevated levels of dalfampridine may increase the risk of seizures.(1,2) PREDISPOSING FACTORS: Renal impairment. PATIENT MANAGEMENT: The US manufacturer of dalfampridine states that the potential benefits of taking OCT2 inhibitors concurrently with dalfampridine should be considered against the risk of seizures. If concurrent use is warranted, carefully monitor patients for adverse effects. Permanently discontinue dalfampridine in patients who have a seizure while on treatment.(1) The UK and Canadian manufacturers of dalfampridine states that concurrent use of dalfampridine and OCT2 inhibitors is contraindicated.(4,5) DISCUSSION: In a single dose clinical study in 23 healthy volunteers, the combined use of cimetidine (400 mg every 6 hours) increased the area-under-curve (AUC) of cimetidine approximately 25% due to a reduction in the clearance of dalfampridine.(1)	4-AMINOPYRIDINE, AMPYRA, DALFAMPRIDINE, DALFAMPRIDINE ER
Betibeglogene Autotemcel/Anti-Retrovirals; Hydroxyurea SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Betibeglogene autotemcel is prepared from apheresed cells that are transduced with a replication defective, self-inactivating lentiviral vector. Antiretrovirals may interfere with the manufacturing of apheresed cells. Hydroxyurea may interfere with hematopoietic stem cell (HSC) mobilization of CD34+ cells.(1) CLINICAL EFFECTS: Use of hydroxyurea before mobilization may result in unsuccessful stem cell mobilization. Use of antiretrovirals before mobilization and apheresis may interfere with the production of betibeglogene autotemcel. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Discontinue antiretrovirals and hydroxyurea for at least one month prior to mobilization and until all cycles of apheresis are completed. If a patient requires antiretrovirals for HIV prophylaxis, then confirm a negative HIV test before beginning mobilization and apheresis of CD34+ cells. DISCUSSION: Antiretroviral medications and hydroxyurea may interfere with the manufacturing of betibeglogene autotemcel therapy.(1)	ZYNTEGLO
Elivaldogene Autotemcel/Anti-Retrovirals SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.

MECHANISM OF ACTION: Atidarsagene autotemcel is prepared from apheresed cells that are transduced with a replication defective, self-inactivating lentiviral vector. Antiretrovirals may interfere with the manufacturing of apheresed cells. CLINICAL EFFECTS: Use of antiretrovirals before mobilization and apheresis may interfere with the production of atidarsagene autotemcel. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Discontinue antiretrovirals for at least one month prior to mobilization (or the expected duration of time needed for elimination of the medication) until all cycles of apheresis are completed. If a patient requires antiretrovirals for HIV prophylaxis, then confirm a negative HIV test before beginning mobilization and apheresis of CD34+ cells. DISCUSSION: Antiretroviral medications may interfere with the manufacturing of atidarsagene autotemcel therapy.(1)	LENMELDY

There are 8 moderate interactions. The clinician should assess the patient’s characteristics and take action as needed. Actions required for moderate interactions include, but are not limited to, discontinuing one or both agents, adjusting dosage, altering administration.

Drug Interaction	Drug Names
Metformin/Dolutegravir SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Dolutegravir may inhibit the renal organic cation transporter, OCT2, responsible for the elimination of metformin.(1) CLINICAL EFFECTS: Concurrent use may result in increased plasma levels of metformin and toxicity such as lactic acidosis. Untreated lactic acidosis may be fatal. Symptoms of lactic acidosis include malaise, myalgias, respiratory distress, low pH, increased anion gap and elevated blood lactate. PREDISPOSING FACTORS: Risk factors for metformin associated lactic acidosis include renal impairment,sepsis, dehydration, excessive alcohol intake, acute or chronic metabolic acidosis, hepatic insufficiency, acute heart failure, metformin plasma levels > 5 micrograms/mL, and conditions which may lead to tissue hypoxia. Geriatric patients may also be at higher risk due to slower metformin clearance and increased half-life in this population. PATIENT MANAGEMENT: With concomitant use, assess the benefit and risk of metformin in patients on dolutegravir. When starting or stopping dolutegravir, the metformin dose may require an adjustment. Monitor blood glucose when initiating concomitant use and after stopping dolutegravir.(1) Monitor patient's renal function and for signs and symptoms of metformin toxicity (lactic acidosis) such as malaise, myalgias, respiratory distress, increasing somnolence, and respiratory distress. Laboratory results which may signal lactic acidosis include: low pH, an increased anion gap, and increased lactate to pyruvate ratio.(1) DISCUSSION: Dolutegravir has been shown to inhibit OCT2 in vitro and in vivo and is expected to inhibit the excretion of metformin.(1) In a study in 15 subjects, concomitant metformin (500 mg twice daily) with dolutegravir (50 mg daily) increased the concentration maximum (Cmax) and area-under-curve (AUC) of metformin by 66% and 79%, respectively. In a study in 15 subjects, concomitant metformin (500 mg twice daily) with dolutegravir (50 mg twice daily) increased the Cmax and AUC of metformin by 111% and 145%, respectively.(1)	ACTOPLUS MET, ALOGLIPTIN-METFORMIN, DAPAGLIFLOZIN-METFORMIN ER, GLIPIZIDE-METFORMIN, GLYBURIDE-METFORMIN HCL, INVOKAMET, INVOKAMET XR, JANUMET, JANUMET XR, JENTADUETO, JENTADUETO XR, KAZANO, METFORMIN ER GASTRIC, METFORMIN ER OSMOTIC, METFORMIN HCL, METFORMIN HCL ER, PIOGLITAZONE-METFORMIN, RIOMET, SAXAGLIPTIN-METFORMIN ER, SEGLUROMET, SITAGLIPTIN-METFORMIN, SYNJARDY, SYNJARDY XR, TRIJARDY XR, XIGDUO XR, ZITUVIMET, ZITUVIMET XR
Dolutegravir-Rilpivirine/Selected Oral Cations; Antacids; H2 Antagonists SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Aluminum, calcium, iron, lanthanum, magnesium, sucralfate, and zinc may form chelation compounds with dolutegravir.(1) Rilpivirine requires an acidic medium for absorption. Antacid or H2 antagonist induced decrease in gastric pH may result in decrease in rilpivirine absorption.(1) CLINICAL EFFECTS: Simultaneous administration or administration of products containing aluminum, calcium, iron, lanthanum, magnesium, and/or sucralfate close to the administration time of dolutegravir may result in decreased absorption and clinical effectiveness of dolutegravir.(1) Simultaneous administration of an antacid or a H2 antagonist may result in decreased levels and effectiveness of rilpivirine, as well as the development of resistance.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: If possible, avoid concurrent therapy with dolutegravir-rilpivirine and cation-containing products. If it is necessary to use these agents concurrently, dolutegravir-rilpivirine should be administered 4 hours before or 6 hours after taking these medications.(1) Alternatively, dolutegravir-rilpivirine and supplements containing calcium or iron can be taken together with food.(1) In patients maintained on dolutegravir-rilpivirine, administer dolutegravir-rilpivirine at least 4 hours before or 6 hours after antacids .(1) In patients maintained on dolutegravir-rilpivirine, administer dolutegravir-rilpivirine at least 4 hours before or 12 hours after H2 antagonists.(1) Concurrent use of proton pump inhibitors will dolutegravir-rilpivirine is contraindicated.(1) DISCUSSION: In a study in 16 subjects, the administration of an antacid (Maalox - aluminum and magnesium hydroxide) simultaneously with dolutegravir (50 mg single dose) decreased the maximum concentration (Cmax), area-under-curve (AUC), and minimum concentration (Cmin) of dolutegravir by 72%, 74%, and 74%, respectively.(1) In a study in 16 subjects, the administration of an antacid (Maalox - aluminum and magnesium hydroxide) 2 hours after dolutegravir (50 mg single dose) decreased dolutegravir Cmax, AUC, and Cmin by 18%, 26%, and 30%, respectively.(1) In a study in 16 subjects, the administration of a multiple vitamin (One-A-Day) simultaneously with dolutegravir (50 mg single dose) decreased dolutegravir Cmax, AUC, and Cmin by 35%, 33%, and 32%, respectively.(1) In a study in 16 subjects, omeprazole (20 mg daily) decreased the Cmax, AUC, and Cmin of rilpivirine (150 mg daily) by 40%, 40%, and 33%, respectively.

The Antiretroviral Pregnancy Registry (APR) monitors pregnancy outcomes in women exposed to dolutegravir/rilpivirine during pregnancy. Clinicians are encouraged to register patients in the APR by calling 800-258-4263 or visiting https://www.apregistry.com/.

Data regarding the use of dolutegravir/rilpivirine in pregnant women are insufficient to date to definitively assess a drug-associated risk for birth defects and miscarriage; however, human data from the APR do not indicate an increased birth defect risk. Of 1,377 dolutegravir exposures during pregnancy resulting in live births, the prevalence of birth defects was 3.3% following first trimester exposure and 5% following second-/third-trimester exposure.

Of 870 rilpivirine exposures during pregnancy resulting in live births, the prevalence of birth defects was 2.1% following first trimester exposure and 0.9% following second-/third-trimester exposure.

There has been a concern regarding the development of neural tube defects in infants exposed to dolutegravir during pregnancy. The first interim analysis from an ongoing birth outcome surveillance study in Botswana identified an association between dolutegravir and an increased risk of neural tube defects when dolutegravir was administered at the time of conception and in early pregnancy. In a larger subsequent analysis, the prevalence of neural tube defects in infants delivered to individuals taking dolutegravir at conception was 0.11%,

which did not differ significantly from that of infants delivered to HIV-positive individuals not administered dolutegravir (0.11%) or to HIV-negative individuals (0.06%). Results from an Eswatini birth outcome surveillance study revealed similar outcomes; the prevalence of neural tube defects in infants delivered to individuals taking dolutegravir at conception was 0.08%, which did not differ significantly from that of infants delivered to individuals taking non-dolutegravir-containing regimens (0.22%) or to HIV-negative individuals (0.08%).

Dolutegravir is distributed into human milk. It is not known whether rilpivirine is distributed into human milk; the drug was present in milk when administered to lactating rats. It is not known whether dolutegravir or rilpivirine affects human milk production or the breastfed infant.

The HHS perinatal HIV transmission guideline provides updated recommendations on infant feeding. The guideline states that patients with HIV should receive evidence-based, patient-centered counseling to support shared decision making about infant feeding. During counseling, patients should be informed that feeding with appropriate formula or pasteurized donor human milk from a milk bank eliminates the risk of postnatal HIV transmission to the infant.

Additionally, achieving and maintaining viral suppression with antiretroviral therapy during pregnancy and postpartum reduces the risk of breastfeeding HIV transmission to <1%, but does not completely eliminate the risk. Replacement feeding with formula or banked pasteurized donor milk is recommended when patients with HIV are not on antiretroviral therapy and/or do not have a suppressed viral load during pregnancy (at a minimum throughout the third trimester), as well as at delivery.

Clinical studies of dolutegravir/rilpivirine did not include a sufficient number of patients >=65 years of age to determine whether they respond differently compared with younger patients. Population pharmacokinetic analyses indicate that age has no clinically important effect on the pharmacokinetics of dolutegravir or rilpivirine. Use dolutegravir/rilpivirine with caution in geriatric patients because of age-related decreases in hepatic, renal, and/or cardiac function and potential for concomitant disease and drug therapy.
