Ep. 385: Tylenol in Pregnancy: Risks, Be...

In this episode of The Birth Lounge Podcast, HeHe sits down with clinical pharmacist Dr. Michaela Wachal to unpack the controversy surrounding Tylenol (acetaminophen) use in pregnancy and its potential links to autism and other neurodevelopmental concerns.

Together, they dive into what the research actually says (and doesn’t say), why transparency and informed consent are so important, and how to navigate decisions around medications in pregnancy with confidence. Dr. Wachal also highlights the bigger picture, like how genetics, environmental toxins, and even maternal stress can play a role in outcomes, and why caring for yourself is just as critical as any prescription.

This conversation is packed with nuance, evidence, and practical takeaways to help you feel informed, empowered, and ready to advocate for yourself as you make decisions about your pregnancy care.
