Registry Information for Pregnant Women
Share your experience with medicines. Sign up for a pregnancy exposure registry. You can help other pregnant women and doctors find out more about the safety of medicines used during pregnancy.
Pregnancy Exposure Registries gather information about how prescription drugs or vaccines affect a pregnant woman and her fetus. You will not be asked to take any new medicines to participate in the study. The pregnancy registry is only interested in medicines that you are already taking.
FDA does not run the pregnancy registry studies. The drug company that makes the medicine is usually in charge of the pregnancy registry. FDA keeps a list of ongoing registries.
How To Sign Up
- Check the list of registries. Look for your medicine or medical condition.
- Get the website and phone number to contact the registry to sign up. For some registries, your doctor, nurse, or midwife may need to sign you up.
- Ask what to expect when you sign up. Each registry has its own policies. When you contact the registry, ask about their policies such as:
- How many times will they contact you?
- How will they keep your information private?
- Who do you contact if you have questions?
- How do you find out the results of the study when the registry has ended?
Other Drug Information
If you do not see your medicine on the list, then there may not be a pregnancy registry for that medicine. You may find other information about your medicine at:
- Medication Guides - Information handouts that come with some prescription medicines.
- Drug Specific Information - List of information on some FDA-approved drugs.
- Daily Med - National Library of Medicine website where you can find information from the drug labels for over 20,000 drugs.
- MotherToBaby , a service of the Organization of Teratology Information Specialists (OTIS) - Call MotherToBaby to speak with a counselor about taking medicines while you are pregnant or breastfeeding. 1-866-626-6847
Better Drug Information is Coming
Prescription drug labeling will be changing over the next few years.
Until now, FDA categorized the risks of taking a drug or biological product during pregnancy under a five-letter system (A, B, C, D and X) based on what was known about that product. But comments received by FDA showed that the letter system was often confusing because it was overly simplistic, and did not reflect the available information. This system could lead to false assumptions about medications based on their category.
The revised labeling will replace the old five-letter system with more helpful information about a medication’s risks to the expectant mother, the developing fetus and the breastfed infant. In addition, the labeling will include contact information for pregnancy exposure registries that collect and maintain data on the effects of medications used by pregnant women.
