Terazosin Pregnancy Warnings

This drug should not be used during pregnancy unless the benefit outweighs the risk to the fetus.

US FDA pregnancy category: C

Animal studies have revealed increased fetal resorptions, decreased fetal weight, and an increased number of supernumerary ribs at a dose 60 times the maximum recommended human dose (MRHD). However, these findings were likely secondary to maternal toxicity. Animal studies have also revealed a significant increase in the number of pup deaths at a dose greater than 75 times the MRHD. There are no controlled data in human pregnancy.

US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
