Anti-Hypertension Medications During Pregnancy

Last Updated on Wednesday, May 01, 2013

The risk of preeclampsia is higher in women with chronic hypertension (high blood pressure), but studies have shown that it is far safer to keep a woman's hypertension under control during pregnancy than to risk preeclampsia superimposed on top of uncontrolled chronic hypertension. The good news is there are many anti-hypertensive medications, and many of them have been successfully and safely used in pregnancy.

"For most drugs in the 2nd and 3rd trimesters, the indications for treatment outweigh potential risks. Treatment should be individualized to meet the specific needs of each woman," said Dr. Tom Easterling, director of the Foundation's medical advisory board. "A few drugs such as angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor antagonists (ARB) do have a potential for harm and are used only under very limited circumstances."

A good source of online information is www.mothertobaby.com, a service of the non-profit Organization of Teratology Information Specialists, dedicated to providing evidence-based information to mothers, health care professionals, and the general public about medications and other exposures during pregnancy and while breastfeeding.

It is important to be knowledgeable about your prescribed medications, and although you may read about them online, it is most important that you review all your medications and supplements with your pregnancy specialist.
