Pregnancy Considerations

In general, women who become pregnant on a stable combination antiretroviral therapy (cART) regimen may continue that regimen if viral suppression is effective, appropriate drug exposure can be achieved, contraindications for use in pregnancy are not present, and the regimen is well tolerated. The Health and Human Services (HHS) Perinatal HIV Guidelines generally do not recommend this combination as initial therapy in antiretroviral-naive pregnant women due to inferior virologic activity (HHS [perinatal] 2016). See individual agents.

Patient Education
