Isek 20 Softgel Capsule contains isotretinoin 20 mg, a retinoid derivative primarily indicated for the treatment of severe recalcitrant nodular acne that is unresponsive to conventional therapies such as antibiotics and topical agents. Isotretinoin exerts its therapeutic effect by reducing sebaceous gland size and sebum production, inhibiting the growth of acne-causing bacteria, and exhibiting anti-inflammatory properties, thereby targeting multiple pathogenic factors of acne. The softgel formulation facilitates optimal bioavailability and patient compliance. Isek 20 is administered orally, typically with meals to enhance absorption, under strict medical supervision due to its potent pharmacological activity and risk profile. Common adverse effects include dry skin, cheilitis, and transient elevations in liver enzymes and lipid levels, necessitating regular monitoring of hepatic function and lipid profile during treatment. Isotretinoin is contraindicated in pregnancy due to its high teratogenic potential; therefore, effective contraception is mandatory for female patients of childbearing potential before, during, and after therapy. Patients should be advised to avoid vitamin A supplements and to report any signs of mood changes or visual disturbances promptly. Isek 20 Softgel Capsule should be prescribed and dispensed by healthcare professionals experienced in managing isotretinoin therapy to ensure safe and effective use.
