Episode notes
Personal Reliance On Tylenol
- Paul Sweeney describes Tylenol as his lifelong 'magic drug' that fixes everything for him.
- Scarlet Fu shares a personal memory of her mother using Tylenol for migraines frequently.
Correlation Versus Causation In Tylenol Studies
- Studies link long-term acetaminophen use in pregnancy to higher autism/ADHD risk but correlation does not prove causation.
- Sibling-analysis studies offer stronger evidence but randomized trials are not feasible.
Limit Prolonged Use During Pregnancy
- Frequent use in studies means more than 28 days of acetaminophen during pregnancy, not short-term treatment of fever.
- Avoid long-term, repeated acetaminophen use in pregnancy unless medically necessary and guided by a physician.
