Topex DX Syrup is used to treat cough due to runny nose, sneezing, and throat irritation. 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. 

Topex DX Syrup is a combination of two drugs: Chlorphenamine maleate and Dextromethorphan hydrobromide. Chlorphenamine maleate works by blocking the action of histamine, a substance responsible for causing allergic reactions.  Dextromethorphan hydrobromide blocks the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough. Together, Topex DX Syrup helps to relieve cough, cold and allergic symptoms. 

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

If you are pregnant or breastfeeding, it is advised to inform your doctor before starting Topex DX Syrup . Topex DX Syrup is not recommended for children below 2 years of age. Topex DX Syrup may cause dizziness, so drive only if you are alert. Avoid alcohol consumption along with Topex DX Syrup as it may cause increased dizziness and drowsiness. Keep your doctor informed about your health condition and medications to rule out any side effects/interactions.

Topex DX Syrup is a combination of two drugs: Chlorphenamine maleate (antihistamine) and Dextromethorphan hydrobromide (cough suppressant).

It helps to provide relief from allergy symptoms such as sneezing, running nose, watery eyes, itching, swelling, and congestion or stiffness. Dextromethorphan hydrobromide belongs to the class of cough suppressants that block the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough.

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 any mucus or phlegm. It usually occurs due to irritation in the airways. Cough is commonly caused as a response to allergy or viral infection, but coughing up mucus is possibly an indication of infection in the respiratory tract.
