    Studysummary This study observed that isotretinoin has a low adverse-effect profile, with most side effects being dose-dependent and reversible, except for rare severe cases leading to discontinuation. Our plain-language summary of this paper — not a Tressless recommendation.
    In a retrospective review of 1743 patients prescribed isotretinoin, 18.5% experienced no adverse effects, while the most common side effect was cheilitis, affecting 78% of patients. Other side effects such as eczema and tiredness were reported by 12% of patients each and were found to be dose-dependent. Only 1.4% of patients discontinued the medication due to adverse effects, which included cheilitis, mood changes, tiredness, eczema, and pregnancy, with no reported cases of suicidal ideation or attempts. The study concluded that isotretinoin is effective with a low adverse effect profile at lower doses, despite potential limitations such as under-reporting of adverse effects and lack of long-term follow-up.
