Special Patient Groups
Pregnancy
Absolutely contraindicated. Isotretinoin is a potent human teratogen, causing severe and life-threatening birth defects (e.g., craniofacial, cardiovascular, CNS abnormalities, intellectual disability). Females of reproductive potential must participate in the iPLEDGE REMS program and use two forms of contraception.
Trimester-Specific Risks:
Lactation
Contraindicated. It is unknown if isotretinoin is excreted in human milk, but due to its high lipophilicity and potential for serious adverse effects in the infant, breastfeeding is not recommended during treatment and for one month after discontinuation.
Pediatric Use
Approved for severe recalcitrant nodular acne in patients 12 years of age and older. Use in younger children is not established and generally not recommended due to potential effects on bone growth (premature epiphyseal closure) and other long-term effects.
Geriatric Use
Not commonly used in the geriatric population for acne. If used, caution is advised due to potential for increased susceptibility to adverse effects (e.g., bone mineral density changes, lipid abnormalities, dry skin/eyes) and presence of comorbidities.
Clinical Information
Clinical Pearls
- Isotretinoin is the most effective treatment for severe acne, often leading to long-term remission or cure.
- The iPLEDGE REMS program is mandatory for all prescribers, pharmacies, and patients to ensure safe use and prevent fetal exposure.
- Patients must commit to using two forms of contraception and having monthly pregnancy tests.
- Dryness of skin, lips, and eyes is a universal side effect; advise patients on moisturizers, lip balms, and artificial tears.
- Monitor for mood changes, including depression and suicidal ideation, and educate patients/families to report any concerns immediately.
- Educate patients about the importance of avoiding sun exposure and certain cosmetic procedures (waxing, dermabrasion, laser) during and after treatment.
Alternative Therapies
- Oral antibiotics (e.g., doxycycline, minocycline, azithromycin)
