Topex Expectorent belongs to a group of medicines called expectorants and cough products used to provide relief from cough. Additionally, Topex Expectorent may also help in providing relief from allergy and nasal congestion due to cold. Coughing (dry or productive) is the body's way of clearing irritants (like allergens, mucus or smoke) from airways, thereby preventing respiratory infection. 
 
Topex Expectorent contains Ammonium chloride, Diphenhydramine hydrochloride, and Sodium citrate. Ammonium chloride helps remove phlegm/mucus from the airways by decreasing its stickiness. Diphenhydramine hydrochloride works by blocking the action of a chemical substance called histamine, which is responsible for causing allergic reactions. Sodium citrate helps in reducing congestion, thereby making it easier to cough out through the mouth. Together, Topex Expectorent provides relief from cough. 
 
You are advised to take Topex Expectorent for as long as your doctor has prescribed it for you, depending on your medical condition. In some cases, you may experience certain common side-effects such as headache, stomach upset, dizziness, tiredness, and dry mouth. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if the side effects persist or worsen.
 
Consult your doctor if you are pregnant or breastfeeding. Topex Expectorent may cause dizziness, so drive only if you are alert. Topex Expectorent should be given to children only if prescribed by the doctor. Avoid consuming alcohol with Topex Expectorent as it could lead to increased dizziness. Inform your doctor about all the prescription, non-prescription and herbal medicines you are taking to rule out any side effects/interactions.

Cough: Coughing is the body's way of clearing irritants (like allergens, mucus or smoke) from airways and preventing infection. Cough can be dry or productive. A productive cough (wet cough) develops sputum (phlegm or mucus) 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 indication of infection in the respiratory tract.
