Rather than focusing only on daily dose, cumulative dose reflects how much medication the body receives overall, which many dermatologists use to help guide long-term treatment planning./p> p classfw-400 lg:font-17 xsm:font-16 text-hex2c2c2c>Historically, treatment courses were designed to reach a cumulative dose of approximately 120–150 mg/kg. Newer research, including a large 2025 cohort analysis, found that patients who reached higher cumulative totals — up to around 220 mg/kg — were less likely to experience acne relapse or need a second course compared with those who received lower totals. This does not mean higher doses are right for everyone, but it suggests cumulative exposure may play a role in long-term durability./p> p classfw-400 lg:font-17 xsm:font-16 text-hex2c2c2c>Cumulative dose should always be individualized by a prescribing clinician based on acne severity, tolerance, and patient-specific factors./p> p classfw-400 lg:font-17 xsm:font-16 text-hex2c2c2c> Example:br> A 70 kg patient taking 40 mg/day reaches about 17 mg/kg each month. At that pace, approaching 150 mg/kg may take around 7–9 months, while higher cumulative targets would take proportionally longer. /p> p classbg-hexf4f4f4 p-10 radius-8 w-max mt-10> a hrefhttps://jamanetwork.com/journals/jamadermatology/article-abstract/2829255 target_blank classtext-gray underline w-auto hover:text-hex2c2c2c relative tooltip-source > Lai J, Barbieri JS.
