Hi, will my foetus be harmed if i took peritol also called cyproheptadine before and during the first few weeks of pregnancy?

Category B medicine: Which means: animal studies show no risk or adverse fetal effects but controlled human 1st trimester studies not avail/do not confirm; no evidence of 2nd or 3rd trimester risk; fetal harm possible but unlikely; see pkg insert drug-specific recs, use with caution, don't exceed recommended dosage, call your treating doctor if in doubt, goodluck

Category B: Good evidence cyproheptadine is safe to take during pregnancy, so highly unlikely. Be well!
