Expar DX 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, namely, 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) produces mucous or sputum.

Expar DX Syrup contains Chlorpheniramine maleate, Phenylephrine and Dextromethorphan hydrobromide. Chlorpheniramine maleate works by blocking the action of histamine, a substance responsible for causing allergic reactions. Phenylephrine helps shrink 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, Expar DX Syrup helps provide relief from dry cough.

Your doctor will recommend the dose and duration of Expar DX Syrup based on your medical condition. Some people may experience dry mouth/throat/nose, drowsiness, blurred vision, constipation, dizziness, restlessness or excitation. Most of these side effects of Expar DX Syrup do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.

Consult your doctor if you are pregnant or breastfeeding. Expar DX Syrup is not recommended for children below 12 years of age. If you are about to undergo medical tests or surgery, please inform your doctor that you are taking Expar DX Syrup. Expar DX Syrup may cause dizziness, so drive or operate machinery only if you are alert. Avoid alcohol consumption as it may cause increased dizziness. Keep your doctor informed about your health condition and medications to rule out any interactions/side effects.

Expar DX Syrup is a combination medicine belonging to a class of drugs called 'cough and cold preparations' primarily used to treat dry cough.

Phenylephrine is a decongestant that helps shrink the blood vessels located in the nasal passage, thereby reducing the stuffy nose.

Cough: Coughing is the body's way of clearing irritants (like allergens, mucus or smoke) from airways and preventing infection. Cough may be dry or productive. A productive cough (wet cough) brings up sputum (phlegm, mucus and other matter) from the lungs. A dry cough does not 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.
