Adult Nighttime Cough DM is a medication designed to help relieve cough and allergy symptoms for individuals aged 12 and over.

This product is particularly useful for temporarily relieving cough caused by minor throat and bronchial irritation, often associated with colds, as well as symptoms from hay fever or other upper respiratory allergies. By addressing these issues, Adult Nighttime Cough DM can help you get a better night's sleep.
