Hmzine 10 Tablet contains Hydroxyzine 10 mg, an antihistamine with anxiolytic, sedative, and antiemetic properties. It is primarily indicated for the management of anxiety and tension associated with psychoneurosis, as well as for the symptomatic relief of pruritus due to allergic conditions such as chronic urticaria, atopic and contact dermatoses. Hydroxyzine exerts its effect by antagonizing central and peripheral histamine H1 receptors, thereby reducing allergic symptoms and producing sedation. Additionally, it has anticholinergic and antiemetic actions, making it useful in controlling nausea and vomiting. Hmzine 10 Tablet is often prescribed as a short-term treatment for anxiety and tension, and as an adjunct in preoperative sedation. The usual adult dosage varies depending on the indication but typically ranges from 25 mg to 100 mg daily, divided into several doses. Caution is advised in patients with a history of hypersensitivity to hydroxyzine or related compounds, and it should be used with care in individuals with impaired hepatic or renal function. Common adverse effects include drowsiness, dry mouth, and dizziness. Patients are advised to avoid alcohol and activities requiring mental alertness while taking this medication.
