When you're pregnant, every pill, supplement, or over-the-counter remedy carries pregnancy risks. It’s not just about what you take—it’s about how it affects your growing baby. Medication safety during pregnancy, the practice of choosing drugs that won’t harm fetal development. Also known as prenatal drug exposure, it’s one of the most overlooked but critical parts of prenatal care. Many women assume that if a drug is available without a prescription, it’s safe. But that’s not true. Even common painkillers like ibuprofen or aspirin can interfere with fetal development, especially in the third trimester. The placenta doesn’t block everything—it lets through a surprising number of chemicals, including some that can alter organ development, brain growth, or even trigger premature labor.
Drug interactions in pregnancy, how two or more medications affect each other when taken during gestation. Also known as fetal drug effects, this isn’t just about the drug itself—it’s about how your changing body processes it. Hormones shift, liver function slows, kidney filtration speeds up—all of this changes how drugs behave. A dose that was fine before pregnancy might become dangerous now. And it’s not just prescription meds. Herbal supplements, acne treatments, and even some cough syrups carry hidden risks. One study found that nearly 1 in 3 pregnant women took at least one medication with potential fetal harm, often without knowing it. The real danger isn’t always the drug itself—it’s the lack of clear information. Many doctors don’t have time to go over every medication, and many patients don’t ask. But you should. Even if you’re taking something you’ve used for years, pregnancy changes the rules.
