NRTIs NRTIs interfere with HIV reverse transcriptase by competitive inhibition. Nucleoside analogue drugs require three intracellular phosphorylation steps to form the triphosphate nucleoside, which is the active drug moiety. The nucleotide analogue tenofovir contains a monophosphate component attached to the adenine base and requires only two phosphorylation steps to form the active moiety.

Dosing in Pregnancy: No change in dose is indicated. For guidance about use of combination products in pregnancy, please see the specific sections on other components (i.e., 3TC, FTC, TDF)	Moderate placental transfer to fetus.^b The FDA advises women to avoid becoming pregnant while taking EFV and advises health care providers to avoid administration during the first trimester of pregnancy, as fetal harm may occur. However, the data on more than 7,900 periconception EFV exposures from Botswana rules out a ≥3-fold increased risk of NTDs. As a result, the current Perinatal Guidelines do not restrict the use of EFV in pregnant women or in women who are planning to become pregnant. This is consistent with both the British HIV Association and WHO guidelines for use of ARV drugs in pregnancy. EFV should be continued in pregnant women who are on a virologically suppressive, EFV-based regimen, because ARV drug changes during pregnancy may be associated with loss of viral control and an increased risk of perinatal transmission (see Pregnant Women Living with HIV Who are Currently Receiving Antiretroviral Therapy).

Repeat lead-in period if therapy is discontinued for >7 days. In patients who develop mild-to-moderate rash without constitutional symptoms during the lead-in period, continue lead-in dosing until rash resolves, but administer for ≤28 days total. Pregnancy PKs in Pregnancy: PKs of immediate-release tablets not significantly altered in pregnancy. No data available on extended-release formulations in pregnancy. Dosing in Pregnancy: No change in dose indicated.	High placental transfer to fetus.^b No evidence of human teratogenicity (can rule out 1.5-fold increase in overall birth defects and 2-fold increase in cardiovascular and genitourinary defects). There is an increased risk of symptomatic liver toxicity when first initiating therapy in women with CD4 counts ≥250/mm³. Liver toxicity is often associated with a rash and can be fatal. Pregnancy does not appear to increase this risk. NVP should be initiated in pregnant women with CD4 counts ≥250 cells/mm³ only if benefit clearly outweighs risk. There is a potential increased risk of life-threatening hepatotoxicity in women with high CD4 counts. Elevated transaminase levels at baseline may increase the risk of NVP toxicity. Women who become pregnant while taking NVP-containing regimens and who are tolerating their regimens well can continue taking those regimens, regardless of their CD4 counts.	December 24, 2019

RPV AUC and trough concentration are 20% to 50% lower in pregnancy than postpartum. While most pregnant women exceeded target exposure, those with detectable viral loads had lower RPV troughs. Dosing in Pregnancy: While RPV plasma concentration is reduced during pregnancy, higher-than-standard doses have not been studied, and there is not enough data available to recommend a dosing change during pregnancy. Pregnant women receiving standard dosing should have their viral loads monitored more frequently than women who are not receiving RPV.

ATV/c (Evotaz): One tablet once daily with food Pregnancy PKs in Pregnancy ATV (Reyataz): ATV concentrations are reduced during pregnancy, and they are further reduced when ATV is given concomitantly with TDF or an H2-receptor antagonist. ATV/c (Evotaz): Use of ATV/c is not recommended during pregnancy, because ATV trough concentrations are 80% to 85% lower than the ATV concentrations seen in nonpregnant adults. Dosing in Pregnancy ATV (Reyataz): Use of unboosted ATV is not recommended during pregnancy. Use of ATV is not recommended for ARV-experienced pregnant women who are taking TDF and an H2-receptor antagonist. Use of an increased dose (ATV 400 mg plus RTV 100 mg once daily with food) during the second and third trimesters results in plasma ATV concentrations equivalent to those seen in nonpregnant adults receiving standard dosing. Although some experts recommend increased ATV dosing in all women during the second and third trimesters, the package insert recommends increased ATV dosing only for ARV-experienced pregnant women in the second and third trimesters who are also receiving either TDF or an H2-receptor antagonist. ATV/c (Evotaz): Insufficient data to make dosing recommendation in pregnancy (see COBI). For guidance about the use of combination products in pregnancy, please see the specific sections on other components (i.e., COBI).

Effect of in utero ATV exposure on infant indirect bilirubin levels is unclear. Nonpathologic elevations of neonatal bilirub have been observed in some, but not all, clinical trials to date. Oral powder (but not capsules) contains phenylalanine, which can be harmful to patients with phenylketonuria. Use of ATV/c is not recommended during pregnancy. See Recommendations for Use of Antiretroviral Drugs During Pregnancy, Table 4, and Table 5 for discussions about avoiding the use of ATV/c during pregnancy.	December 24, 2019

High placental transfer to fetus.^b No evidence of teratogenicity in rats, or rabbits. In pregnancy surveillance data from Botswana, there was a slightly increased risk of NTDs in infants born to women who initiated DTG prior to pregnancy and who were receiving it at the time of conception. DTG may be used as part of a Preferred regimen in all pregnant women at all gestational ages and as part of an Alternativeregimen in women who are trying to conceive. Clinicians should discuss the risks and benefits of DTG use with the patient. For more information, see Updated Guidance About the Use of Dolutegravir in Pregnancy in Recommendations for Use of Antiretroviral Drugs During Pregnancy. To maximize DTG absorption, doses should not be administered within 2 hours of ingesting any preparation that contains minerals such as iron or calcium, including prenatal vitamins.	December 12, 2019

In Patients Who Are Receiving Rifampin: Two RAL 400-mg, film-coated tablets (800 mg) twice daily without regard to food Pregnancy PK in Pregnancy: Decreased drug concentrations in third trimester are not of sufficient magnitude to warrant a change in dosing. Dosing in Pregnancy: No change in dose is indicated. Once-daily dosing (i.e., two RAL 600-mg, film-coated tablets) should not be used in pregnant women until more information is available.	High placental transfer to fetus.^b No evidence of human teratogenicity (can rule out 1.5-fold increase in overall birth defects). There is a case report of markedly elevated liver transaminases with RAL use in late pregnancy. Severe, potentially life-threatening, and fatal skin and HSRs have been reported in nonpregnant adults. RAL chewable tablets contain phenylalanine. To maximize RAL absorption, doses should not be administered within 2 hours of ingestion of any preparation containing minerals such as iron or calcium, including prenatal vitamins.	January 17, 2020

Oral Solution: Take with food. With EFV or NVP in PI-Naive or PI-Experienced Patients: LPV/r 500 mg/125 mg tablets twice daily without regard to meals (use a combination of two LPV/r 200 mg/50 mg tablets and one LPV/r 100 mg/25 mg tablet), or LPV/r 520 mg/130 mg oral solution (6.5 mL) twice daily with food Pregnancy PKs in Pregnancy: Lower RTV levels are seen during pregnancy than during postpartum, which may reduce the pharmaco-enhancing effect of RTV in pregnancy. RTV Dosing in Pregnancy: No dose adjustment necessary when RTV is used as booster. LPV/r Dosing in Pregnancy: Once-daily dosing is not recommended during pregnancy. Some experts recommend that an increased dose (i.e., LPV/r 600 mg/150 mg twice daily without regard to meals or LPV/r 500 mg/125 mg twice daily without regard to meals) should be used in the second and third trimesters, especially in PI-experienced pregnant women and women who start treatment during pregnancy with a baseline viral load >50 copies/mL. When standard dosing is used, monitor virologic response and, if possible, LPV drug levels. For guidance about use of combination products in pregnancy, please see the specific sections on other components (i.e., LPV/r).	Low placental transfer to fetus.^b No evidence of increased risk of human teratogenicity (can rule out 1.5-fold increase in overall birth defects). RTV should only be used as low-dose booster for other PIs. RTV oral solution contains 43% alcohol and therefore is not recommendedfor use during pregnancy, because there is no known safe level of alcohol exposure during pregnancy. LPV/r oral solution contains 42% alcohol and 15% propylene glycol and is not recommended for use in pregnancy. Once-daily LPV/r dosing is not recommended during pregnancy..	December 24, 2019
