Instoid 10 Soft Gelatin Capsule contains Isotretinoin 10 mg, a potent retinoid primarily indicated for the treatment of severe recalcitrant nodular acne that is unresponsive to conventional therapies such as antibiotics and topical agents. Isotretinoin acts by reducing sebaceous gland size and sebum production, inhibiting comedogenesis, and exerting anti-inflammatory effects, thereby addressing multiple pathogenic factors of acne. Each soft gelatin capsule delivers a precise 10 mg dose of isotretinoin to ensure optimal therapeutic efficacy while minimizing adverse effects. Instoid 10 is prescribed under strict medical supervision due to its well-documented teratogenicity and potential for serious side effects, including mucocutaneous dryness, elevated liver enzymes, hyperlipidemia, and mood alterations. Patients undergoing treatment are advised to adhere to regular monitoring protocols, including liver function tests, lipid profiles, and pregnancy tests for women of childbearing potential. The medication should be taken with food to enhance absorption. Instoid 10 is contraindicated in pregnancy, breastfeeding, and in individuals with hypersensitivity to isotretinoin or any capsule components. Proper patient counseling on adherence, potential side effects, and the necessity of effective contraception is essential to ensure safe and effective use of Instoid 10 Soft Gelatin Capsules in managing severe acne vulgaris.
