Typical dosage for Xolair

Your allergist will decide your dose of Xolair and might adjust it over time. The dose depends on things like your body weight, your serum IgE level, and how well the medication is working for you.

Xolair is injected under the skin, usually in the front and middle of your thigh or in your stomach area (at least 2 inches away from your belly button).If a caregiver gives the shot, it can also go in the back of your upper arm.
