What is the pregnancy category for Losartan Potassium?

Losartan Potassium is classified as a Category D medication during pregnancy. This classification indicates that there is evidence of fetal risk based on human data or adverse effects observed in animal studies. However, the potential benefits of the medication may justify its use in pregnant women despite the potential risks.

For medications classified as Category A, there is no evidence of risk to the fetus in human studies. Category B indicates that animal studies have not demonstrated a risk to the fetus, but there are no adequate studies in pregnant women. Category C shows that animal studies have indicated an adverse effect but there are no well-controlled studies in humans. Given that Losartan is known to potentially cause harm to the fetus, especially during the second and third trimesters, these categories do not apply, confirming that none of them accurately reflect Losartan's classification.
