Excerpt from Table 8
Note: When using FDC tablets, refer to other sections in Appendix B and Table 8 for information about the dosing and safety of individual drug components of the FDC tablet during pregnancy.
|Formulation||Dosing Recommendationsa||Use in Pregnancy|
|Standard Adult Dose of RTV (Norvir) When Used as PK Booster for Other PIs:
PKs in Pregnancy:
|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 recommended for 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.
a Individual ARV drug doses may need to be adjusted in patients with renal or hepatic insufficiency (for details, see the Adult and Adolescent Antiretroviral Guidelines, Appendix B, Table 10).
b Placental transfer categories are determined by mean or median cord blood/maternal delivery plasma drug ratio:
Key: ARV = antiretroviral; EFV = efavirenz; LPV/r = lopinavir/ritonavir; NVP = nevirapine; PI = protease inhibitor; PK = pharmacokinetic; RTV = ritonavir
