Nucala 100 mg Injection belongs to the class of 'immunomodulators', primarily used to treat asthma. Asthma is a respiratory condition in which airways narrow, swell, and produce extra mucus, leading to difficulty in breathing. Nucala 100 mg Injection is used as an add-on maintenance treatment in severe asthma patients above six years of age and in patients with chronic rhinosinusitis with nasal polyps. It is also used in the treatment of hypereosinophilic syndrome and eosinophilic granulomatosis.

Nucala 100 mg Injection consists of Mepolizumab as an active ingredient, which binds itself to interleukin-5 (IL-5) and stops it from attaching to its receptor on the surface of eosinophil white blood cells, specifically the alpha subunit of the receptor. It works by preventing the body's natural production of certain chemicals that increase asthma symptoms, like coughing, wheezing, chest pain, and breathing difficulties.

Nucala 100 mg Injection may cause common side effects such as fever, back pain, itching, headache, sore throat, and breathing difficulty. These side effects resolve over time. Inform your doctor if any of these side effects bother you. Nucala 100 mg Injection will be administered by a healthcare professional. Do not self-administer
