Xolair Precautions

A severe allergic reaction called anaphylaxis has happened in some patients after they received Xolair. Anaphylaxis is a life-threatening condition and can lead to death so get emergency medical treatment right away if symptoms occur.

Signs and Symptoms of anaphylaxis include:

wheezing, shortness of breath, cough, chest tightness, or trouble breathing
low blood pressure, dizziness, fainting, rapid or weak heartbeat, anxiety, or feeling of “impending doom”
flushing, itching, hives, or feeling warm
swelling of the throat or tongue, throat tightness, hoarse voice, or trouble swallowing

Get emergency medical treatment right away if you have signs or symptoms of anaphylaxis after receiving Xolair.

Anaphylaxis from Xolair can happen:

right after receiving a Xolair injection or hours later
after any Xolair injection. Anaphylaxis has occurred after the first Xolair injection or after many Xolair injections.

Your healthcare provider should watch you for some time in the office for signs or symptoms of anaphylaxis after injecting Xolair. If you have signs or symptoms of anaphylaxis, tell your healthcare provider right away.

Your healthcare provider should instruct you about getting emergency medical treatment and further medical care if you have signs or symptoms of anaphylaxis after leaving the doctor’s office.

Xolair Food Interactions

Medicines can interact with certain foods. In some cases, this may be harmful and your doctor may advise you to avoid certain foods. In the case of Xolair there are no specific foods that you must exclude from your diet when receiving Xolair.

Before receiving Xolair, tell your doctor:

if you are allergic to Xolair or any other medicine.
if you will be traveling to (or live in) areas that have high risk for parasitic infections.
if you are pregnant.
if you are breastfeeding.

Tell your doctor about all the medicines you take including prescription medicines, vitamins, and herbal supplements.

Xolair Dosage

Your doctor will determine the Xolair dose you require. The dose varies depending on your weight and your IgE level. IgE is a natural substance in your body that that is elevated in allergic asthma. A blood test is used to test your IgE level.

Xolair FDA Warning

WARNING: Anaphylaxis

Anaphylaxis presenting as bronchospasm, hypotension, syncope, urticaria, and/or angioedema of the throat or tongue, has been reported to occur after administration of Xolair. Anaphylaxis has occurred as early as after the first dose of Xolair, but also has occurred beyond 1 year after beginning regularly administered treatment. Because of the risk of anaphylaxis, observe patients closely for an appropriate period of time after Xolair administration. Health care providers administering Xolair should be prepared to manage anaphylaxis that can be life-threatening. Inform patients of the signs and symptoms of anaphylaxis and instruct them to seek immediate medical care should symptoms occur.
