Leecet Syrup contains Cetirizine 5mg/5ml, a second-generation antihistamine used primarily for the relief of allergy symptoms. Cetirizine acts as a selective antagonist of peripheral H1 histamine receptors, effectively reducing the effects of histamine, a substance in the body that causes allergic symptoms. Leecet Syrup is indicated for the treatment of allergic conditions such as allergic rhinitis (including seasonal and perennial allergies), chronic urticaria, and other dermatological allergic manifestations. It provides symptomatic relief from sneezing, runny nose, itchy and watery eyes, and itching of the nose or throat. The syrup formulation allows for easy administration, particularly in pediatric patients or individuals who have difficulty swallowing tablets. Leecet Syrup is generally well tolerated, with a low incidence of sedation compared to first-generation antihistamines. Common side effects may include headache, dry mouth, and fatigue. It is important to use Leecet Syrup as directed by a healthcare professional, and caution is advised in patients with renal impairment or those taking other central nervous system depressants. Leecet Syrup should not be used in individuals with known hypersensitivity to cetirizine or any of its excipients.
