Xolair Injection Overview
Xolair is a prescription medication available as an injection that helps manage severe allergic conditions. It is designed to target and reduce the effects of immunoglobulin E (IgE), a type of antibody that plays a key role in allergic reactions.
Treatment for Severe Allergic Conditions
Xolair is primarily used to treat severe allergic conditions, such as:
- Asthma: Xolair is used for patients with moderate to severe persistent asthma who have not responded adequately to other asthma treatments. It helps control asthma symptoms by blocking the release of inflammatory chemicals triggered by IgE.
- Chronic Spontaneous Urticaria (CSU): Xolair is used for adults and adolescents with severe CSU, a condition characterized by persistent hives. It works by reducing the IgE levels in the body, thereby reducing the severity and frequency of hives.
Mechanism of Action
Xolair works by binding to IgE, preventing it from attaching to mast cells and basophils. These cells are responsible for releasing inflammatory chemicals that trigger allergic reactions. By blocking IgE, Xolair reduces the release of these chemicals, thereby mitigating the symptoms of allergic conditions.
Xolair Administration and Dosage
Xolair is administered as an injection, typically given by a healthcare professional. The dosage and frequency of Xolair injections vary depending on the individual’s condition, weight, and response to treatment.
Dosage Regimen
The standard dosage regimen for Xolair involves an initial loading dose followed by maintenance doses.
- Loading Dose: The initial dose is typically 300 mg for adults and 150 mg for children weighing less than 30 kg. This dose is administered as a single injection.
- Maintenance Doses: After the loading dose, maintenance doses are given every two weeks. The maintenance dose is typically 150 mg for adults and 75 mg for children weighing less than 30 kg.
Routes of Administration
Xolair is administered by subcutaneous injection, meaning it is injected under the skin. This method is generally considered safe and effective.
Frequency of Injections
Xolair injections are typically given every two weeks. The frequency of injections may be adjusted based on the individual’s response to treatment.
