1 What is Xolair?

Brand: Xolair

Generic: Omalizumab

Xolair is an IgE blocker used for the treatment of moderate to severe persistent allergic asthma. This drug is used when asthma cannot be controlled sufficiently by other asthma drugs.

This drug cannot relieve an asthma attack that has already begun. Chronic idiopathic urticaria can also be treated with this drug especially in patients who continue to have hives that are not controlled by an antihistamine.

IgE plays an important role in allergic asthma as it is produced when allergens are present in the body. This drug blocks the production of IgE. This drug is to be given only by or under the direct supervision of your healthcare professional.

2 What to Know Before Using

Before using Xolair, you must know all about the risks and complications associated with it. Inform your healthcare provider for any allergic reactions to these drugs or any other drugs, foods, dyes, preservatives, or animals.

Carefully read the label of non-prescription drugs for any possible allergic reaction or contraindications. Use of omalizumab injection in children younger than 12 years of age is not recommended while safety and efficacy have not been established.

Studies in the elderly have not demonstrated any geriatric-specific problems that would limit the utility of omalizumab injection. Indications of harm to the fetus have not been reported in animal studies but studies in pregnant women or animals are still inadequate.

Infant risk is still undetermined when using this drug during breastfeeding. Discuss with your healthcare professional about the potential risks and benefits of taking this drug while breastfeeding.

Drugs should not be taken together to prevent any interactions but in necessary cases inquire your healthcare provider regarding the adjustments in dosage or any other necessary precautions to prevent any unwanted side effects.

Inform your healthcare professional if you are taking any other prescription or nonprescription drugs. Intake of specific food or using alcohol or tobacco with this drug is associated with an increased risk of certain side effects. Your healthcare professional can give you special instructions about the use of food, alcohol, or tobacco.

Inform your healthcare professional if you have any other medical problems such as asthma attack, bronchospasm, other allergic conditions, cancer, or parasitic infections.

Your dose will be determined by your healthcare professional based on your IgE level and body weight. The number of injections per dose will be determined by your healthcare professional. Each dose will be given in a different place on your body if you need more than 1 injection.

This drug cannot treat sudden asthma attacks. It is not a substitute for the drugs you are already taking. Check with your healthcare professional before you suddenly stop taking, or change the dose of your inhaled steroids or any other asthma drug.

You will receive this drug every 4 weeks for the treatment of chronic idiopathic urticaria. Consult with your healthcare professional for any concerns.
