Why is this medication prescribed?

Mepolizumab is a prescription medication used to treat certain types of severe asthma and a condition called eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome. It is typically prescribed by a healthcare provider and administered by injection.

• Prescribed for Severe Asthma: Mepolizumab is often prescribed for individuals with severe asthma that is characterized by frequent exacerbations and symptoms that are not well-controlled with standard asthma medications such as inhaled corticosteroids and long-acting beta-agonists. It is particularly beneficial for those with eosinophilic asthma, a type of asthma characterized by high levels of eosinophils (a type of white blood cell) in the blood and airways.
• Prescribed for EGPA: Mepolizumab is also used in the treatment of eosinophilic granulomatosis with polyangiitis (EGPA), a rare autoimmune disease that can affect various organs in the body, including the lungs, skin, and nerves. This condition is characterized by high levels of eosinophils and inflammation in the blood vessels.

How should this medicine be used?

Mepolizumab is typically administered as a subcutaneous (under the skin) injection. Here are some general guidelines on how it should be used:

• Dosage: The specific dosage and frequency of Mepolizumab injections will be determined by your healthcare provider based on your condition and medical history.
• Administration: Mepolizumab is usually self-administered by the patient or a caregiver at home. Your healthcare provider will provide detailed instructions on how to properly prepare and administer the injection. It is important to follow these instructions carefully.
• Injection Site: Mepolizumab is injected into the thigh or abdomen. Your healthcare provider will provide guidance on where to inject.
• Rotating Injection Sites: It is important to rotate the injection site with each dose to minimize the risk of skin irritation or injection site reactions.
• Storage: Store Mepolizumab as directed by your healthcare provider or the medication’s packaging. Typically, it should be kept in the refrigerator at a specific temperature range, but some formulations may be stored at room temperature for a limited time.
• Monitoring: Your healthcare provider may monitor your condition and adjust the dosage as needed to ensure optimal control of your asthma or EGPA.
• Adherence: It is crucial to adhere to the prescribed dosing schedule and not miss any injections unless directed otherwise by your healthcare provider.

As with any medication, it’s important to discuss the potential benefits and risks of Mepolizumab with your healthcare provider. They can provide personalized guidance on its use, and you should report any side effects or concerns promptly to your healthcare team.

Other uses for this medicine

Mepolizumab is primarily prescribed for the treatment of severe asthma and eosinophilic granulomatosis with polyangiitis (EGPA).

What side effects can this medication cause?

Mepolizumab injection is generally well-tolerated, but like any medication, it can cause side effects in some individuals. Not everyone will experience these side effects, and the severity can vary from person to person. Common side effects of Mepolizumab may include:

• Headache: Mild to moderate headaches are one of the more common side effects reported with Mepolizumab.
• Injection Site Reactions: Some people may experience mild redness, swelling, or itching at the injection site. These reactions are usually not serious and tend to improve on their own.
• Back Pain: Back pain is another relatively common side effect of Mepolizumab.
• Fatigue: Some individuals may experience fatigue or tiredness.
• Upper Respiratory Tract Infections: In clinical trials, upper respiratory tract infections (such as the common cold) have been reported in some patients.

It’s important to note that these side effects are not experienced by everyone, and many people tolerate Mepolizumab well without significant issues. Additionally, side effects are typically mild to moderate in intensity.

While less common, there are also some potential serious side effects associated with Mepolizumab, although these are rare. These can include:

• Allergic Reactions: Severe allergic reactions to Mepolizumab are rare but can occur. Seek immediate medical attention if you experience symptoms such as difficulty breathing, swelling of the face, lips, tongue, or throat, or severe itching.
