“Hydryllin DM Syrup is effective for managing dry, irritating cough that disturbs rest or daily activity. The combination of Dextromethorphan and Diphenhydramine helps reduce cough intensity and throat irritation. It should not be used for chronic cough due to asthma, smoking, or emphysema unless prescribed. Patients should remain cautious about drowsiness, and pregnant or breastfeeding women should only take it after medical advice.”
