Is adapalene safe during pregnancy?

What does the evidence say about adapalene during pregnancy?

1. Topical retinoids, including adapalene and tretinoin, are generally recommended to be avoided during pregnancy, a caution rooted in the fact that retinoids taken by mouth are established to cause birth defects. 1
2. Less than 0.01% of a topical adapalene dose reaches the bloodstream, and what little is absorbed clears from plasma within about 72 hours, though prescribing guidance still says to use it in pregnancy only if the potential benefit justifies the potential risk to the fetus. 2
3. Systemic absorption of most topical retinoid medications is low, and animal studies on adapalene specifically haven't shown the teratogenic signal seen with tretinoin, though routine use during pregnancy still isn't recommended given how mixed the overall evidence remains. 3
4. Adapalene is also generally advised against during breastfeeding, since there isn't enough data to rule out risk to a nursing infant. 2
5. Oral isotretinoin's strict rules, including monthly pregnancy testing and a mandatory two-method birth control program, exist because oral retinoids have a clear, well-documented link to birth defects. Topical adapalene sits at a very different exposure level, which is part of why the two get such different handling despite both being retinoids. 4

Is adapalene safe in each trimester?

• First trimester. Many people are already using adapalene when they find out they're pregnant. Animal research on adapalene specifically hasn't shown the same signal seen with tretinoin, and topical absorption is very low, but clinicians still generally suggest pausing it and switching to a pregnancy-friendlier routine for now.
• Second trimester. There's no new trimester-specific concern here. If you paused adapalene early on, this is a reasonable stretch to settle into azelaic acid, a gentle cleanser, or another option your provider is comfortable with instead.
• Third trimester. The guidance doesn't change late in pregnancy. Keep the conversation about restarting adapalene for your postpartum visit, especially if you're planning to breastfeed, since that's a separate question from pregnancy.
