It works by blocking interleukin-5 (IL-5), reducing the eosinophils that drive airway inflammation. It is given as a fixed 100 mg subcutaneous injection once every 4 weeks, alongside your usual asthma medications, under specialist supervision.<\/p>\n<\/div>\n<h2 id=\"key-facts\">Key Facts Table<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Item<\/th>\n<th>Details<\/th>\n<\/tr>\n<tr>\n<td>Active ingredient<\/td>\n<td>Mepolizumab (humanized IgG1 monoclonal antibody)<\/td>\n<\/tr>\n<tr>\n<td>Strength<\/td>\n<td>100 mg pre-filled syringe or autoinjector<\/td>\n<\/tr>\n<tr>\n<td>Drug class<\/td>\n<td>Biologic \u2014 anti-interleukin-5 (IL-5 antagonist)<\/td>\n<\/tr>\n<tr>\n<td>Main use<\/td>\n<td>Add-on maintenance treatment for severe eosinophilic asthma (12 years and older)<\/td>\n<\/tr>\n<tr>\n<td>Dosing<\/td>\n<td>100 mg subcutaneously once every 4 weeks<\/td>\n<\/tr>\n<tr>\n<td>Route<\/td>\n<td>Subcutaneous injection (upper arm, thigh, or abdomen)<\/td>\n<\/tr>\n<tr>\n<td>Storage<\/td>\n<td>Refrigerator 2\u20138\u00b0C; protect from light; do not freeze<\/td>\n<\/tr>\n<tr>\n<td>Prescription status<\/td>\n<td>Prescription only \u2014 specialist supervision<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"short-desc\">Short Description<\/h2>\n<p>Nucala (mepolizumab) is an EMA- and FDA-approved biologic that neutralizes interleukin-5, the key cytokine responsible for eosinophil growth and survival.

Nucala was the first anti-IL-5 biologic approved for this &#8220;eosinophilic&#8221; asthma phenotype, offering a targeted way to calm this specific inflammatory pathway rather than escalating steroid doses indefinitely.<\/p>\n<hr \/>\n<h2 id=\"what-is\">What Is Nucala?<\/h2>\n<p>Nucala is a humanized monoclonal antibody (mepolizumab) that targets interleukin-5 (IL-5) with high affinity. It is approved as an add-on maintenance treatment for severe eosinophilic asthma in patients 12 years and older, and is also used in related eosinophil-driven conditions such as eosinophilic granulomatosis with polyangiitis (EGPA), hypereosinophilic syndrome (HES), and chronic rhinosinusitis with nasal polyps (CRSwNP), always alongside standard therapy.<\/p>\n<hr \/>\n<h2 id=\"how-works\">How Does It Work?<\/h2>\n<p>IL-5 is the principal cytokine responsible for the growth, activation, and survival of eosinophils, the white blood cells central to allergic and eosinophilic airway inflammation. Mepolizumab binds IL-5 and prevents it from attaching to its receptor on eosinophils. Blocking this signal sharply reduces circulating and airway eosinophil counts, calming the inflammation that drives asthma exacerbations in this specific patient group.<\/p>\n<hr \/>\n<h2 id=\"benefits\">Main Benefits<\/h2>\n<ul>\n<li>Significantly reduces the rate of clinically significant asthma exacerbations.<\/li>\n<li>Can help reduce reliance on maintenance oral corticosteroids in appropriate patients.<\/li>\n<li>Improves asthma control, quality of life, and in some studies, lung function.<\/li>\n<li>Fixed 100 mg dose simplifies administration \u2014 no weight-based calculation needed.<\/li>\n<li>Sustained clinical and pharmacodynamic response demonstrated over years of use in long-term studies.<\/li>\n<li>Can be self-injected at home after training, using a pre-filled syringe or autoinjector.<\/li>\n<\/ul>\n<hr \/>\n<h2 id=\"use-cases\">Real Use Cases<\/h2>\n<ul>\n<li>A patient with frequent asthma exacerbations despite high-dose inhaled corticosteroids and a second controller.<\/li>\n<li>A patient relying on repeated oral corticosteroid courses for asthma flares who needs a steroid-sparing option.<\/li>\n<li>A patient with confirmed elevated blood eosinophil counts and a history of exacerbations.<\/li>\n<li>A patient with EGPA, HES, or CRSwNP being managed by the relevant specialist alongside standard therapy.<\/li>\n<\/ul>\n<hr \/>\n<h2 id=\"best-for\">Who Is It Best For?<\/h2>\n<p>Patients aged 12 years and older with severe eosinophilic asthma that remains uncontrolled despite high-dose inhaled corticosteroids plus another controller medication, with blood eosinophil counts supporting an eosinophilic phenotype, under specialist (pulmonology\/allergy) care.<\/p>\n<hr \/>\n<h2 id=\"avoid\">Who Should Avoid It?<\/h2>\n<ul>\n<li>Anyone with hypersensitivity to mepolizumab or any excipient.<\/li>\n<li>Patients with an active parasitic (helminth) infection should be treated first; screening is recommended before starting, especially with relevant travel history.<\/li>\n<li>Nucala is not intended for treatment of acute asthma exacerbations or acute bronchospasm.<\/li>\n<li>Caution in patients with a history of severe hypersensitivity reactions to biologics generally.<\/li>\n<\/ul>\n<hr \/>\n<h2 id=\"how-to-use\">How to Use Correctly<\/h2>\n<ol>\n<li>Inject 100 mg subcutaneously once every 4 weeks into the upper arm, thigh, or abdomen.<\/li>\n<li>Continue your other prescribed asthma medications; Nucala is an add-on, not a replacement.<\/li>\n<li>Let the syringe or autoinjector reach room temperature before injecting, per the leaflet.<\/li>\n<li>Rotate injection sites and avoid areas that are tender, bruised, red, or hard.<\/li>\n<li>Use each device once and dispose of it in a sharps container.<\/li>\n<li>Do not stop other asthma controllers or oral corticosteroids abruptly; any dose reduction is managed gradually by your specialist.<\/li>\n<\/ol>\n<hr \/>\n<h2 id=\"best-time\">Best Time to Use<\/h2>\n<p>Set a fixed day each month for your injection (every 4 weeks) and keep a reminder, since the interval is longer than weekly biologics and easier to lose track of.

With consistent monthly dosing, continued use of standard inhaled therapy, and specialist-guided monitoring, it provides a valuable option where conventional treatment has fallen short.
