Concerned about medication use during pregnancy? You're not alone.
In this episode of The MotherToBaby Podcast, host Chris Stallman, MS, CGC (genetic counselor, mom of four, teratogen information specialist) sits down with Dr. Judy C. Morrow of Harvard Medical School to break down how FDA REMS (Risk Evaluation and Mitigation Strategy) programs help reduce the risk of birth defects and protect pregnant patients.

Together, they discuss:
✔️ What REMS programs are and why they exist
✔️ How REMS programs support safe medication use
✔️ The role of manufacturers, prescribers, and pharmacists
✔️ Common medications with REMS programs (including isotretinoin/Accutane)
✔️ Pregnancy testing requirements & pharmacy restrictions
✔️ Why some drugs don't have REMS (even if risks exist)
✔️ What patients should ask if they're prescribed a REMS-covered medication

Dr. Morrow shares how researchers use real-world data to identify medication-related adverse events in pregnancy, how REMS programs try to prevent exposed pregnancies, and why communication between patients, providers, and pharmacists is essential.

If you're pregnant, planning a pregnancy, breastfeeding, or support patients in these settings, this episode offers clear, practical insights to help guide informed decision-making.

In this special Folic Acid Awareness Week episode of The MotherToBaby Podcast, host and genetic counselor Chris Stallman sits down with Dr. Elisabeth Marnik, PhD—a biomedical scientist, mom, and science communicator better known as @ScienceWhizLiz on Instagram. Together, they unpack the science behind folic acid, its critical role in early pregnancy, and why it's one of the most important (yet misunderstood) nutrients for people of childbearing age.

From real talk on neural tube defect prevention to busting social media myths like "folic acid causes tongue ties" or "MTHFR mutations mean folic acid isn't safe," this episode is packed with science-backed insights and practical guidance for both healthcare providers and future parents alike.

🧠 Key Topics Covered:

• What folic acid is and why it matters for pregnancy

• The difference between folic acid and folate

• When folic acid is most critical (hint: before you know you're pregnant!)

• Myths and misinformation about folic acid—especially on social media

• What the research really says about MTHFR gene mutations

• How to support patients with dietary restrictions or supplement concerns

• Why more folic acid is not always better

Show Notes:
In this episode of the MotherToBaby Podcast, host and genetic counselor Chris Stallman welcomes Dr. Emily Caffrey, a certified health physicist at the Health Physics Society and the University of Alabama at Birmingham. Together, they dive into one of the most frequently asked topics: how radiation exposure may impact breastfeeding.

Dr. Caffrey explains the difference between ionizing and non-ionizing radiation, details how imaging procedures like X-rays, CT scans, and MRIs interact with the body, and addresses concerns around contrast agents and radioactive tracers. The episode also covers what breastfeeding women working around radiation should know, including practical safety tips and case-by-case considerations.

Key Takeaways:

• Diagnostic imaging procedures do not make breast milk radioactive or require stopping breastfeeding

• Some radioactive tracers or therapeutic treatments may require temporary or permanent changes to breastfeeding plans, depending on the specific agent and dose

• Always inform your healthcare provider that you're breastfeeding and ask questions about any upcoming procedures

• Expert help is available—don't rely on internet searches alone
