Blood Pressure Home > Hyzaar and Pregnancy
A fetus exposed to Hyzaar before birth could potentially experience kidney problems, developmental problems with the nervous and cardiovascular systems, and deformities of the head and face. Despite these warnings, Hyzaar may still be given to a pregnant woman if her healthcare provider believes that its benefits outweigh the possible risks to the unborn child.
Is Hyzaar Safe During Pregnancy?Hyzaar® (losartan potassium-hydrochlorothiazide) is not recommended for use during pregnancy and comes with a warning of fetal toxicity. This is because during pregnancy, Hyzaar can lead to temporary or permanent problems, including death, in the unborn child.
What Is Pregnancy Category D?The U.S. Food and Drug Administration (FDA) categorizes Hyzaar as a pregnancy Category D medication for all three trimesters.
The FDA uses a category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category D is given to medicines that have shown clear evidence of risk to the fetus in the studies. Despite these warnings, a pregnancy Category D medicine may still be given to a pregnant woman if her healthcare provider believes that its benefits outweigh the possible risks to the unborn child.
