Prescription · Contraindicated
Can you use Tretinoin (All-Trans Retinoic Acid) during pregnancy?
⚠️Medical Deferral Notice
Strictly contraindicated. Suspend use immediately and consult your OB-GYN. Cosmetic classifications are formulation flags to discuss with your healthcare provider, not medical clearance.
Clinical Summary
Direct prescription retinoic acid binds directly to nuclear RAR receptors and is strictly contraindicated in pregnancy.
Pharmacological Mechanism & Teratogenic Context
Tretinoin does not require enzymatic oxidation to become active; it directly modulates gene transcription. Given documented retinoid embryopathy mechanisms and variable skin barrier penetration (especially in inflamed acne or dermatitis), ACOG and FDA label warnings mandate immediate cessation upon conception or when attempting pregnancy.
