Why is this medication prescribed?

Efgartigimod alfa-fcab Injection is prescribed for the treatment of certain autoimmune disorders, particularly generalized myasthenia gravis (gMG). Myasthenia gravis is a chronic autoimmune neuromuscular disease characterized by weakness and fatigue of voluntary muscles.

Efgartigimod alfa-fcab works by targeting and neutralizing antibodies that attack the body’s own tissues, which is a characteristic feature of autoimmune diseases like myasthenia gravis. By reducing the levels of these harmful antibodies, efgartigimod helps to alleviate the symptoms associated with the condition and improve muscle function.

How should this medicine be used?

Efgartigimod alfa-fcab Injection is typically administered under the supervision of a healthcare professional, such as a doctor or nurse, in a clinical setting like a hospital or infusion center. Here’s a general guideline on how it is used:

• Monitoring: During the infusion, the patient will be closely monitored for any signs of adverse reactions or complications. Vital signs such as blood pressure, heart rate, and respiratory rate may be monitored regularly throughout the infusion process.
• Post-Infusion Care: After the infusion is complete, the patient may be observed for a period of time to ensure there are no immediate adverse effects. The healthcare provider will provide any necessary post-infusion instructions or follow-up care recommendations.
• Subsequent Infusions: Depending on the prescribed treatment regimen, patients may require multiple infusions of efgartigimod alfa-fcab over a specified period of time. The frequency and duration of treatment will be determined by the healthcare provider based on the individual patient’s response to therapy and the goals of treatment.
