Special Patient Groups
Pregnancy
Absolutely contraindicated. Isotretinoin is a potent human teratogen. Even a single dose can cause severe birth defects.
Trimester-Specific Risks:
Lactation
Contraindicated. It is not known if isotretinoin is excreted in human milk, but due to its potential for serious adverse reactions in nursing infants, breastfeeding is not recommended during treatment and for at least one month after stopping.
Pediatric Use
Safety and efficacy not established in pediatric patients under 12 years of age. Use in adolescents (12-17 years) is common for severe nodular acne, with dosing similar to adults. Growth plate closure should be monitored in younger adolescents.
Geriatric Use
Clinical studies did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Not commonly used in this population for acne. Use with caution due to potential for increased susceptibility to adverse effects (e.g., bone effects, lipid abnormalities).
Clinical Information
Clinical Pearls
- iPLEDGE program compliance is mandatory for all patients, prescribers, and pharmacies. No exceptions.
- Two forms of effective contraception must be used by female patients of childbearing potential, starting one month before, during, and for one month after treatment.
- Patients should be counseled extensively on potential psychiatric side effects, including depression and suicidal ideation. Any new or worsening symptoms warrant immediate discontinuation and psychiatric evaluation.
- Dryness of skin, lips, and eyes is almost universal. Advise patients on frequent use of moisturizers, lip balm, and artificial tears.
- Avoid blood donation during and for one month after treatment due to teratogenic risk.
- Patients should avoid vigorous physical activity that could lead to muscle or joint injury, as isotretinoin can cause musculoskeletal pain and elevated CPK.
Alternative Therapies
- Oral antibiotics (e.g., doxycycline, minocycline, azithromycin)
- Topical retinoids (e.g., tretinoin, adapalene, tazarotene)
- Topical antibiotics (e.g., clindamycin, erythromycin)
