Diphenhydramine Expectorant is a pleasant, raspberry flavoured syrup which is indicated in the control of dry, unproductive cough, and in the alleviation of nasal and bronchial congestion.

Diphenhydramine Expectorant contains Diphenhydramine Hydrochloride, which has central sedative, local anaesthetic, spasmolytic and anticholinergic (diminishes upper respiratory tract secretions) properties, in addition to its main antihistaminic actions.
In addition, a relatively high ammonium chloride content provides an effective expectorant action reducing the viscosity of the mucus, which can then act as a demulcent, thereby protecting inflamed and irritated surfaces and inducing a productive cough which is less exhausting and less painful to the patient.
