Xolair (omalizumab) prefilled syringe is an injectable monoclonal antibody used to treat moderate to severe allergic asthma, chronic spontaneous urticaria (chronic hives), and chronic rhinosinusitis with nasal polyps. It works by binding to IgE antibodies, reducing the allergic response that triggers symptoms.

How is this medication used?

Inject the prescribed dose under the skin every two or four weeks, as determined by your doctor based on your weight and IgE levels. The first doses are typically given under medical supervision; some patients may later self-inject after proper training. Rotate injection sites with each dose.

What are the possible side effects?

Common side effects include injection site reactions (redness, swelling, pain), headache, joint pain, and dizziness. A rare but serious risk is anaphylaxis (severe allergic reaction), which can occur even after previous doses, so know the warning signs and how to respond.

What are the potential interactions?

There are no major known drug interactions with Xolair, though it is often used alongside other asthma or allergy medications under medical supervision. Do not stop your other asthma medications abruptly. Tell your doctor about all medications you take.
