Assurex D Syrup is 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 the airways.

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

Take Assurex D Syrup as prescribed. Your doctor will recommend how often you need to take Assurex 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 Assurex D Syrup do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.

Cough: Coughing is the body's way of clearing irritants (like allergens, mucus or smoke) from airways and preventing infection. Coughs may be dry or productive. A productive cough (wet cough) brings up sputum (phlegm, mucus and other matter) from the lungs, whereas, a dry cough doesn't produce sputum. Cough is commonly caused as a response to allergy or viral infection, but coughing up mucus is possibly an infection in the respiratory tract.
