Episode notes
Tylenol Is The Safer Pregnancy Option
- Acetaminophen (Tylenol) is the common first-line fever and pain treatment in pregnancy because alternatives (NSAIDs) carry known risks.
- Suggesting Tylenol causes autism could cause pregnant people to avoid it and risk higher fevers with worse pregnancy outcomes.
Paracetamol Access Varies By Country
- Sophie recounts being denied paracetamol in the UK and needing an ID at checkout, illustrating regional differences in access.
- Christopher contrasts that with North America where acetaminophen is over-the-counter and commonly used in pregnancy.
Treat Fever Symptoms During Pregnancy
- Treat symptomatic fever and pain during pregnancy; there is no reason to suffer needlessly.
- If you are uncomfortable, use acetaminophen rather than enduring pain or high fever.
