Derivent-LS Drops is used to treat cough associated with mucus. 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) produces mucous or sputum.

Derivent-LS Drops is a combination of three drugs, namely Levosalbutamol, Ambroxol, and Guaiphenesin. Levosalbutamol works by relaxing muscles and widening the airways of the lungs. Ambroxol works by thinning and loosening phlegm (mucus) in the lungs, windpipe, and nose. Therefore, it helps cough out phlegm easily. Guaiphenesin increases the volume of fluid in the airways, reduces the stickiness of mucus, and helps to remove it from the airways. Together, Derivent-LS Drops helps relieve the cough.

Your doctor will recommend the dose and duration of Derivent-LS Drops based on your medical condition. Some people may experience certain common side effects such as nausea, vomiting, drowsiness, headache, dizziness, skin rash, tremors, stomach upset and diarrhoea.

Cough: Coughing is the body's way of clearing irritants (like allergens, mucus or smoke) from airways and preventing infection. The 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/phlegm. 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.
