Hyline 10 Tablet contains Hydroxyzine 10 mg, a first-generation antihistamine with potent anxiolytic, sedative, antiemetic, and anticholinergic 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 and atopic dermatitis. Hydroxyzine acts by competitively inhibiting H1 histamine receptors, thereby reducing the effects of histamine in the body. Additionally, it exerts central nervous system depressant effects, contributing to its anxiolytic and sedative actions. Hyline 10 Tablet is also utilized as a premedication to induce sedation and reduce anxiety before surgical procedures. The recommended dosage should be individualized based on the patient’s clinical condition, age, and response to therapy, with caution advised in elderly patients and those with impaired hepatic or renal function. Common side effects include drowsiness, dry mouth, and dizziness, which generally subside with continued use. Contraindications include hypersensitivity to Hydroxyzine or related compounds. Use during pregnancy and lactation should be avoided unless clearly necessary. Hyline 10 Tablet should be used under strict medical supervision to ensure safety and efficacy.
