Isotretinoin

IsotretinoinActive

Oral retinoid prescribed for severe acne. Drop holds its place and won't schedule it — the course belongs to the prescriber.

What it does

Isotretinoin is taken orally (most often as a 4–6 month course) for severe nodulocystic acne. Side effects can be significant and require medical monitoring. We surface the contraindication in case it appears in a user's product list, but this is not a routine ingredient — it's a derm-supervised treatment.

The evidence, graded

expert consensusOral isotretinoin is a confirmed human teratogen. First-trimester exposure carries a high risk of major birth defects, and no dose is considered safe in pregnancy — this is an absolute contraindication, not a precaution. It is prescription-only and, in the US, dispensed under a mandatory pregnancy-prevention program (iPLEDGE) requiring contraception and regular pregnancy testing. It is an oral course a clinician manages, not a skincare ingredient, and Drop does not schedule it.Lammer 1985 · New England Journal of Medicine
expert consensusOral isotretinoin is not off-limits to teenagers: it is approved in the US for severe recalcitrant nodular acne from age 12, and the current AAD acne guideline strongly recommends it for severe or scarring acne that has failed other options. But it is not something anyone starts alone — every US course runs through a restricted dispensing program (iPLEDGE) with certified prescribers and lab monitoring, and the label carries adolescent bone-density cautions. Drop does not schedule it at any age.Upsher-Smith 2022 · DailyMed (U.S. National Library of Medicine) — FDA Structured Product Label
