Clinical Effects

In clinical studies, people taking omalizumab had fewer asthma symptoms, compared to those not taking it. This medicine also reduced the number of asthma exacerbations, helping to prevent severe attacks. However, omalizumab is not an asthma cure.
In studies of omalizumab for treating chronic idiopathic urticaria, the drug significantly reduced both itching and hives. 

When and How to Take This Medicine

Some general considerations for when and how to take omalizumab include the following:
  • This medication is injected just under the skin. Generally, your healthcare provider will administer it.
  • Omalizumab is given every two to four weeks.
  • Because some people have allergic reactions to omalizumab, your healthcare provider may want to watch you for a while after you receive your injection.
  • For this drug to work properly, it must be used as prescribed. Omalizumab will not work if you stop taking it.

Dosing With Omalizumab

The dose your healthcare provider recommends will vary, depending on a number of factors, including:
  • Your weight
  • The condition being treated
  • The results of a lab test measuring your IgE level.
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
