How is Xolair (omalizumab) administered?

Xolair (omalizumab) is administered subcutaneously, meaning that it is delivered via an injection into the fatty tissue just under the skin. This method of administration is ideal for Xolair because it allows for a controlled release of the medication into the bloodstream over time.

Subcutaneous injections are typically performed in a clinical setting or can sometimes be done by the patient at home after proper training. This route is particularly effective for biologic medications like Xolair, which are often larger molecules that may not be suitable for oral or other forms of administration.

In contrast, oral administration would involve taking the medication by mouth, which is not how Xolair is formulated to work. Similarly, intranasal and intravenous methods do not match the recommended delivery method for this specific medication. Intranasal routes may be effective for certain other medications that target respiratory conditions, while intravenous administration is used for medications that need to act quickly or to achieve higher concentrations in the bloodstream, but this is not the case for Xolair.
