Terazosin Pregnancy Warnings

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

US FDA pregnancy category: Not assigned

Risk summary: Insufficient data are available on the use of this drug in pregnant women to inform a drug-related risk.

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 Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.
