Dxfyln M 400mg/10mg Tablet is used to treat and prevent asthma and chronic obstructive pulmonary diseases (COPD). Asthma is a breathing problem in which airways narrow, swell and produce extra mucus, leading to difficulty breathing. COPD is a group of lung diseases that mainly include emphysema (shortness of breath) and chronic bronchitis (inflammation of the lining of your bronchial tubes).

Dxfyln M 400mg/10mg Tablet is a combination of two medicines: Doxofylline (bronchodilator) and Montelukast (leukotriene receptor antagonist). Doxofylline works by relaxing muscles and widening the airways of the lungs. It treats the airflow obstruction in the lungs, thereby relieving chest tightness, wheezing and cough to make breathing easier. Montelukast blocks the leukotrienes (chemicals released in response when a body comes in contact with an allergen), thereby reducing inflammation and swelling in the nose. It also inhibits bronchoconstriction (narrowing of airways in the lungs that lead to breathing difficulties).

Your doctor will advise the dose and duration of the course based on the severity of your disease. The common side effects of Dxfyln M 400mg/10mg Tablet include fever, nausea, vomiting, stomach pain/epigastric pain, headache, insomnia (difficulty in sleeping), irritation, sore throat, increased heart rate and flu-like symptoms. Most of these side effects of Dxfyln M 400mg/10mg Tablet do not require any medical attention and gradually resolve over time. However, if the side effects are persistent, please reach out to your doctor.

Asthma: It is a chronic (long-term) respiratory condition in which airways narrow, swell, and produce extra mucus, leading to difficulty in breathing. The symptoms of asthma include wheezing (whistling sound while breathing), shortness of breath, chest tightness, and cough, especially at night. The symptoms of mild persistent asthma may occur more than 2 times a week and up to 4 nights in a month, whereas, in the case of severe persistent asthma, the symptoms occur several times every day and most nights. The treatment for asthma includes medication, breathing exercises, and self-care. 

Chronic obstructive pulmonary disease (COPD): It is a group of lung diseases with emphysema (shortness of breath) and chronic bronchitis (inflammation of the lining of bronchial tubes). The major cause of COPD is smoking tobacco. Also, long-term exposure to fumes and chemicals may lead to COPD. The symptoms include chronic cough, shortness of breath or wheezing (whistle sound while breathing).
