Lupicof DX Syrup is a combination medication containing Chlorpheniramine Maleate (2mg/5ml) and Dextromethorphan Hydrobromide (10mg/5ml), formulated to provide symptomatic relief in conditions associated with cough and allergic manifestations. Chlorpheniramine Maleate is an antihistamine that exerts its effect by competitively inhibiting H1 histamine receptors, thereby alleviating symptoms such as rhinorrhea, sneezing, and itching associated with allergic rhinitis and other hypersensitivity reactions. Dextromethorphan Hydrobromide acts centrally on the cough center in the medulla to suppress the cough reflex, making it effective in managing non-productive coughs. Lupicof DX Syrup is indicated for patients experiencing cough accompanied by allergic symptoms such as nasal congestion and watery eyes. The syrup formulation allows for ease of administration, particularly in pediatric and adult populations requiring precise dosing. It is important to use this medication under medical supervision, especially in patients with a history of respiratory conditions, liver impairment, or those taking monoamine oxidase inhibitors. Common side effects may include drowsiness, dizziness, dry mouth, and gastrointestinal disturbances. Patients are advised to avoid driving or operating machinery until they know how the medication affects them. Lupicof DX Syrup should be stored in a cool, dry place, away from direct sunlight.
