Buckley's Cough Suppressant is used to temporarily relieve cough symptoms associated with the common cold, minor bronchial irritations, and other upper respiratory conditions. It addresses dry, hacking coughs by reducing the frequency and intensity of the urge to cough.
The active ingredient dextromethorphan acts on the cough center in the brain (medulla oblongata) to suppress the cough reflex. Some Buckley's formulations also contain menthol, which provides a cooling sensation that can help soothe irritated throat tissues.
Do not use in children under 12 years old without medical advice. Avoid combining with MAO inhibitors or alcohol. Consult a healthcare provider if cough persists beyond 7 days, is accompanied by fever, or produces excess mucus. May cause drowsiness in some individuals.
