Isotretinoin is a retinoid that targets the pilosebaceous unit to manage severe acne conditions.

- Severe nodular acne: reduces inflammatory lesions, prevents new nodule formation, and improves skin appearance. - Acne vulgaris: decreases comedones and inflammatory papules in patients with moderate to severe disease. - Recalcitrant acne: provides systemic control when topical therapies are insufficient.

Isotretinoin may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Dry skin - Cheilitis (cracked lips) - Dry eyes - Photosensitivity - Muscle aches - Headache

Serious or Rare Side Effects: - Severe depression or suicidal ideation - Inflammatory bowel disease - Elevated liver enzymes - Hypertriglyceridemia - Teratogenicity (birth defects) - Visual disturbances

When prescribing isotretinoin, clinicians should observe several safety precautions to minimize risks.

- Pregnancy contraindication: do not prescribe to pregnant women; ensure effective contraception. - Laboratory monitoring: baseline and periodic liver function tests and lipid profiles are recommended. - Avoid vitamin A supplementation: concurrent use may increase toxicity. - Avoid tetracycline antibiotics: may reduce isotretinoin efficacy. - Counsel on sun protection: increased photosensitivity requires sunscreen use. - Store at ambient temperature below 25°C: keep in the original pack, protect from moisture and light.

Isotretinoin interacts with several medicines; some combinations should be avoided while others require careful monitoring.

Major Interactions (Avoid): - Tetracyclines: reduced isotretinoin efficacy. - Vitamin A supplements: increased risk of toxicity. - Systemic corticosteroids: heightened risk of pseudotumor cerebri.

Moderate Interactions (Monitor Closely): - Oral contraceptives: possible reduction in contraceptive effectiveness. - Anticoagulants: potential alteration of INR values. - Lipid‑lowering agents: may affect triglyceride levels.
