Jefcorlin 100 Injection contains Hydrocortisone 100 mg, a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties. It is indicated for the management of various conditions including severe allergic reactions, adrenal insufficiency, acute exacerbations of chronic inflammatory diseases, and certain autoimmune disorders. Hydrocortisone acts by inhibiting the release of substances in the body that cause inflammation, thereby reducing swelling, redness, and allergic symptoms. The injectable form allows for rapid onset of action, making it suitable for emergency situations such as anaphylaxis or shock. Jefcorlin 100 Injection should be administered intramuscularly or intravenously under strict medical supervision, with dosage tailored according to the severity of the condition and patient response. Caution is advised in patients with infections, diabetes, hypertension, or peptic ulcers, as corticosteroids may exacerbate these conditions. Long-term use requires monitoring for potential adverse effects including immunosuppression, osteoporosis, and adrenal suppression. Abrupt discontinuation should be avoided to prevent withdrawal symptoms. This formulation is intended for use by healthcare professionals only and should be stored according to manufacturer guidelines to maintain efficacy and safety.
