Medications to Avoid During Pregnancy

When you're pregnant, every pill, supplement, or OTC remedy carries a new kind of weight. Medications to avoid during pregnancy, drugs that can cross the placenta and interfere with fetal development. Also known as teratogenic agents, these substances don’t just affect you—they can cause birth defects, growth problems, or even miscarriage. This isn’t about fear. It’s about knowing what’s safe and what’s not—so you can protect your baby without giving up your health.

Some of the most dangerous medications to avoid during pregnancy, include certain blood thinners, acne treatments, and mood stabilizers. For example, Ginkgo Biloba, a common herbal supplement. Also known as herbal blood thinner, it increases bleeding risk during delivery and has been linked to fetal brain hemorrhages in case reports. Then there’s Accupril, an ACE inhibitor used for high blood pressure. Also known as lisinopril-class drug, it’s been shown to cause kidney damage and low amniotic fluid in developing babies. Even something as simple as omeprazole, a heartburn pill. Also known as PPI medication, can lower vitamin B12 levels in the fetus over time, affecting nerve development. These aren’t theoretical risks. Real women have had babies born with complications after taking them.

It’s not just prescription drugs. Over-the-counter painkillers like ketorolac, a strong NSAID sold as Toradol. Also known as injectable painkiller, can shut down fetal kidney function in the third trimester. And don’t assume natural means safe. Some herbal teas, supplements, and even high-dose vitamins can trigger problems. The key isn’t to avoid all meds—it’s to know which ones are worth the risk and which aren’t. That’s why your doctor needs to review every pill you take, even if it’s labeled "natural" or "safe for moms."

You’ll find real stories here—cases where women took something they thought was harmless and ended up facing unexpected consequences. You’ll also find clear alternatives: what to use instead of Accupril, what to reach for when you have heartburn, how to manage anxiety without risking your baby’s brain. This isn’t a list of warnings. It’s a guide to making smarter choices, one decision at a time.
