Koffly-DX Syrup Sugar Free is a multi-symptom relief medication formulated to alleviate nasal congestion, allergic symptoms, and cough associated with common cold, flu, and upper respiratory tract infections. Each 5 ml dose 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 with anticholinergic properties, helps relieve allergic symptoms such as sneezing, runny nose, and watery eyes by blocking histamine H1 receptors. Dextromethorphan Hydrobromide 10 mg serves as a centrally acting antitussive, suppressing the cough reflex in the medulla oblongata without causing respiratory depression. This sugar-free formulation is suitable for diabetic patients or those requiring sugar restriction. Koffly-DX Syrup Sugar Free should be used as directed by a healthcare professional, with caution advised in patients with hypertension, glaucoma, or thyroid disorders due to potential side effects of phenylephrine. It is contraindicated in individuals hypersensitive to any of the active ingredients and should not be combined with monoamine oxidase inhibitors. Adverse effects may include dizziness, dry mouth, or mild sedation. Consultation with a healthcare provider is recommended before use, especially in pediatric, pregnant, or lactating patients.
