MotherToBaby: Trusted Pregnancy and Medication Safety Resources

When you're pregnant or breastfeeding, every pill, supplement, or cold medicine matters. MotherToBaby, a trusted service that provides evidence-based information on how medications and exposures affect pregnancy and breastfeeding. Also known as Teratogen Information Systems, it's run by experts who translate complex medical data into simple, practical advice for parents. This isn't just about avoiding drugs—it's about understanding which ones are safe, which need adjustments, and when you need to talk to your doctor.

Many people worry about taking antidepressants like citalopram or escitalopram during pregnancy, or whether immunosuppressants could harm a developing baby. Others wonder if progesterone supplements like Prometrium are safe for early pregnancy, or if statins might affect fetal development. MotherToBaby answers these exact questions, using real data from clinical studies and thousands of parent reports. It also covers things most sites ignore—like how a single dose of Benadryl might interact with your tricyclic antidepressant, or whether ginger for morning sickness is truly safe in the first trimester. The service doesn’t just list risks—it explains degrees of risk, timelines, and alternatives.

What makes MotherToBaby different is its focus on real-life use. It doesn’t just say "avoid this drug." It tells you that while certain medications carry small risks, stopping them might be riskier—for example, uncontrolled autoimmune disease during pregnancy can lead to preterm birth more often than the drug itself. It also tracks how exposures change across trimesters, and what happens when you switch from one medication to another while nursing. You’ll find answers to questions like: Can I keep taking my blood pressure meds? Is it safe to use azelaic acid for acne while pregnant? What about that new weight loss drug tirzepatide? The posts below cover exactly these concerns, from calcium’s role in fetal bone development to how naloxone fits into opioid safety plans for expectant mothers. Whether you’re planning a pregnancy, currently pregnant, or breastfeeding, what you’ll find here isn’t theory—it’s what real families have used to make confident, informed choices.
