Isotretinoin is a retinoid that acts on the pilosebaceous unit to treat severe forms of acne. - Severe nodular acne: reduces inflammatory lesions, prevents new nodule formation and decreases sebum output. - Acne vulgaris refractory to other treatments: clears existing lesions and limits further breakouts. - Cystic acne: diminishes cyst formation and promotes faster skin healing.

Isotretinoin may cause a range of adverse reactions.

Common Side Effects: - Dry skin and mucous membranes: dryness of skin, lips, and eyes. - Cheilitis: cracking and inflammation of the lips. - Nasal irritation: frequent nosebleeds. - Photosensitivity: increased susceptibility to sunburn. - Elevated triglycerides: rise in blood lipid levels.

Serious or Rare Side Effects: - Teratogenicity: severe birth defects if exposure occurs during pregnancy. - Depression or suicidal ideation: mood changes requiring monitoring. - Inflammatory bowel disease: onset or worsening of Crohn's disease or ulcerative colitis. - Hepatotoxicity: significant elevation of liver enzymes.

Isotretinoin requires careful monitoring and specific safety measures. - Pregnancy: contraindicated; ensure effective contraception before, during, and after therapy. - Liver function: obtain baseline and periodic liver enzyme tests. - Lipid profile: monitor triglycerides and cholesterol regularly. - Vitamin A intake: avoid additional vitamin A supplements to prevent toxicity. - Store below 25°C: keep in the original packaging, protect from moisture and direct light.

Isotretinoin can interact with several medications, altering efficacy or safety.

Major Interactions (Avoid): - Tetracyclines: increased risk of intracranial hypertension. - Vitamin A supplements: additive retinoid toxicity. - Systemic corticosteroids: may reduce isotretinoin effectiveness.

Moderate Interactions (Monitor Closely): - Oral antifungals (e.g., ketoconazole): may affect isotretinoin metabolism. - Warfarin: potential alteration of INR values. - Enzyme inducers (e.g., phenobarbital, carbamazepine): may lower isotretinoin plasma levels.
