Brezvent LS Syrup is a combination of respiratory medications used to treat coughs 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, 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) means mucous or sputum is produced to help clear your airways. 

Brezvent LS Syrup consists of three medicines: Ambroxol, Guaifenesin and Salbutamol. Ambroxol is an 'expectorant' that promotes the secretion of sputum/cough and a 'mucolytic agent' that makes sputum less viscous to make breathing easier. On the other hand, Salbutamol belongs to the class of drugs known as 'bronchodilators' that widen and relax the airways (bronchi) of the lungs. Guaifenesin is also an 'expectorant'. It works by reducing the thickness or viscosity of bronchial secretions (phlegm) and increasing mucus flow, making it easier to cough. 

Your doctor will decide the dose and duration of the course based on the severity of your disease. Like every other medication, Brezvent LS Syrup also has common side effects like nausea, vomiting, diarrhoea, stomach pain, upset stomach, dizziness, headache, skin rash, tremor (shakiness), palpitations (uneven heartbeat), muscle cramps, and increased heart rate. These side effects, if occurred, generally go away during the treatment. However, if the side effects are persistent, reach out to your doctor.

It is mandatory to inform your doctor if you have heart, liver, kidney diseases, stomach ulcers, seizure (fits), high blood pressure, thyroid disorders, diabetes, inflammation of air passages, lung disorders, and difficulty breathing before taking Brezvent LS Syrup .
