Acute asthma attacks: Xolair (Omalizumab) will not help to stop an asthma attack and should not be used to treat an acute asthma attack. If you start developing an asthma attack, be sure to use your "reliever" medication for rapid relief of your asthma symptoms.

Cancer: Although early studies comparing those taking Xolair (Omalizumab) and those not taking Xolair (Omalizumab) showed a small difference in the percentage of people developing cancer, additional observation and studies have shown that this is not the case.

Corticosteroid withdrawal: Oral or inhaled corticosteroids for asthma should not be stopped suddenly when treatment with Xolair (Omalizumab) is started. Decreases in corticosteroid doses should be closely supervised by your doctor. Check with your doctor before stopping or decreasing the dose of any of your asthma medications.

Heart problems: Xolair (Omalizumab) has been linked to heart problems, although the exact frequency with which this happens is not clear. If you have any heart problems, such as abnormal heart rhythms, heart failure, or a history of Heart Attack, discuss with your doctor how Xolair (Omalizumab) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Xolair (Omalizumab), and whether any special monitoring is needed.

Kidney function: Xolair (Omalizumab) has not been studied for use by people with kidney problems. If you have reduced kidney function or Kidney Disease, discuss with your doctor how Xolair (Omalizumab) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Xolair (Omalizumab), and whether any special monitoring is needed.

Liver function: Xolair (Omalizumab) has not been studied for use by people with liver problems. If you have reduced liver function or liver disease, discuss with your doctor how Xolair (Omalizumab) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Xolair (Omalizumab), and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking Xolair (Omalizumab).

Parasite infections: Xolair (Omalizumab) may weaken your resistance to parasite infections. If you are living in or travelling to a region where parasite infections are frequent, discuss with your doctor any special precautions that may be needed.

Serum sickness: In rare cases, serum sickness can occur with the use of Xolair (Omalizumab). This is a delayed allergic reaction that can happen at any time during treatment with Xolair (Omalizumab) and occurs between 1 and 5 days after an injection. If you experience painful joints or muscles, swollen lymph nodes with a rash and fever, contact your doctor immediately.

Severe allergic reactions: Although rare, severe allergic reactions to Xolair (Omalizumab) may occur. After your injection, the doctor may ask you to remain at the office or clinic for a short period of time. This way, if you do have an allergic reaction, medical attention will be nearby.

If you experience sudden difficulty breathing, fainting, swelling of the throat or tongue, or severe dizziness (especially when rising from a sitting or lying position), get medical attention immediately.

Stroke: Although rare, there is the possibility of experiencing a stroke when using Xolair (Omalizumab).
