A nurse or other trained health professional will give you this medicine. Omalizumab is given as a shot under your skin.
You will receive omalizumab once every 2 or 4 weeks. Your dose will be determined by your IgE level, which your doctor will measure with a simple blood test before treatment begins, and your body weight. Based on your dose, your doctor will also tell you if you will need 1, 2, or 3 injections per dose. If you need more than 1 injection, each will be given in a different place on your body.
Omalizumab is not a rescue medication and should not be used to treat sudden asthma attacks. It is not a substitute for the medicines you are already taking. Never suddenly stop taking, or change the dose of your inhaled steroids or any other asthma medicine you are taking unless your doctor tells you to do so.
This medicine should come with a Medication Guide. Read and follow these instructions carefully. Ask your doctor if you have any questions.
