Cufdyn-D Syrup belongs to a class of medication called 'cough and cold preparations' primarily used to treat dry cough. Coughing (dry or productive) is the body's way of clearing irritants (like allergens, mucus or smoke) from airways and preventing infection. There are two types of coughs: dry cough and chesty cough. A dry cough is tickly and doesn't produce any vicious or thick mucus, while a chesty cough (wet cough) means mucous or sputum is produced to help clear your airways. 

Cufdyn-D Syrup is a combination of three drugs, namely: Chlorpheniramine (antihistamine), Phenylephrine (decongestant) and Dextromethorphan (cough suppressant). Chlorpheniramine works by blocking the action of histamine, a substance responsible for causing allergic reactions. Phenylephrine helps shrink the blood vessels in the nasal passage, reducing a stuffy nose. Dextromethorphan works by blocking the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough. Collectively, it helps to provide relief from dry cough.

Cufdyn-D Syrup should be taken as prescribed by the doctor. Your doctor will recommend how often you take Cufdyn-D Syrup based on your medical condition. Some people may experience dry mouth, throat or nose, drowsiness, blurred vision, constipation, dizziness, restlessness or excitation. Most of these side effects of Cufdyn-D Syrup do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.
