Incodex Syrup Sugar Free is a combination oral medication formulated to provide symptomatic relief from respiratory conditions characterized by nasal congestion, allergic rhinitis, and cough. Each 5 ml of the syrup contains Phenylephrine 5 mg, a selective alpha-1 adrenergic receptor agonist that acts as a decongestant by constricting nasal blood vessels, thereby reducing swelling and nasal congestion. Chlorpheniramine Maleate 2 mg, an antihistamine, alleviates allergic symptoms such as sneezing, runny nose, and watery eyes by blocking H1 histamine receptors. Dextromethorphan Hydrobromide 15 mg serves as a centrally acting antitussive agent that suppresses the cough reflex by acting on the cough center in the medulla, providing relief from dry, non-productive cough. The sugar-free formulation makes Incodex Syrup suitable for diabetic patients and those requiring calorie-restricted diets. It is indicated for temporary relief of symptoms associated with common cold, allergic rhinitis, and upper respiratory tract infections. Caution is advised in patients with hypertension, cardiovascular diseases, glaucoma, or those taking monoamine oxidase inhibitors. The medication should be used as directed by a healthcare professional to avoid potential side effects such as dizziness, drowsiness, or gastrointestinal discomfort.
