The group of blood pressure medications in question, so-called ACE inhibitors that include such top-sellers as Altace, Lotrel, and Lisinopril, have been found to significantly increase the risk of heart and brain defects in infants when their mothers take the drugs during the earliest months of pregnancy. It had previously been thought that ACE inhibitors only had a negative effect if taken during the second and third trimesters of pregnancy.

ACE inhibitors are already required by the FDA to carry a "black box warning" on their label that describes the dangers of second and third trimester use. The FDA has stated that the most recent findings will require further study to determine if the warning will be expanded to include first trimester usage.

Experts warn pregnant women who are currently taking blood pressure medication against suddenly stopping treatment, as high blood pressure can be very dangerous to both mother and baby.

If you are taking any kind of blood pressure medication and are pregnant or planning to become pregnant, you should talk to your doctor to find the best and safest way to treat your condition.
