Omalizumab
About Omalizumab
Omalizumab is an injection used to treat severe allergic asthma, long-lasting hives with no known cause, and chronic nasal polyps. It is prescribed when standard treatments do not fully control these symptoms. This medicine helps lower the frequency of severe flare-ups and eases persistent breathing or skin issues.
This medicine is typically injected every 2 or 4 weeks, and it must be taken consistently to remain effective over time. Along with taking this medicine, avoiding personal allergy triggers like dust mites, pet dander, or specific foods can help you achieve better results. Your doctor can help you identify these triggers and create a management plan.
While using Omalizumab, you may experience mild side effects like headache, joint pain, or mild swelling at the injection site. However, you must seek medical attention immediately if you notice serious symptoms such as swelling of the throat, severe dizziness, or trouble breathing. It is important to monitor how you feel after each injection.
Do not take this if you have had a severe allergic reaction to this medicine or any of its ingredients in the past. Talk to your doctor before starting this medicine if you have a history of cancer, severe allergies, or parasitic infections. This medicine may not be suitable for everyone, so a thorough medical review is necessary.
Let your doctor know about all other medicines you take, as certain vaccines or immune therapies may interact with Omalizumab. If you are pregnant, breastfeeding, or an older adult, consult your doctor or pharmacist to understand the safety of using this medicine. They will help you weigh the benefits and potential risks.
Uses of Omalizumab
Medicinal Benefits
Omalizumab is a biologic medicine used to manage certain allergic conditions, including allergic asthma, chronic spontaneous urticaria, and nasal polyps. It works by targeting immunoglobulin E (IgE), an important mediator of allergic inflammation.
- Helps Control Allergic Asthma: Reduces allergic inflammation and may decrease the frequency of asthma exacerbations in people with appropriately diagnosed severe allergic asthma.
- Reduces Chronic Hives: Helps reduce the number and severity of hives and may relieve associated itching in people with chronic spontaneous urticaria.
- Helps Manage Nasal Polyps: May reduce nasal congestion and the size of nasal polyps, helping improve breathing and other associated symptoms.
- Reduces the Need for Rescue Treatment: Better control of allergic inflammation may reduce asthma exacerbations and the need for additional rescue treatments in appropriate patients.
- Improves Daily Comfort: Better control of asthma, hives, or nasal symptoms may improve sleep, daily functioning, and overall quality of life.
Directions for Use
- Follow your doctor’s instructions on the dosage and timing of this medication.
- Hold the syringe straight and inject it under the skin, typically in the thigh, abdomen, or upper arm.

Habit Forming
Diet & Lifestyle Advise
- Identify and Avoid Triggers: Minimise exposure to personal asthma and allergy triggers, such as tobacco smoke, dust mites, pollen, mould, and pet dander.
- Keep a Symptom Diary: Record asthma symptoms, hive flare-ups, nasal symptoms, and the dates of your injections to help your doctor assess how well your treatment is working.
- Wear Comfortable Clothing: Choose loose-fitting, breathable clothing to reduce friction and skin irritation if you experience chronic hives.
- Avoid Excessive Heat: Avoid very hot baths and showers, as heat may worsen itching or trigger hives in some people.
Patients Concern
Disease/Condition Glossary
Allergic Asthma: Allergic asthma occurs when inhaling allergens like pollen, dust mites, mold, or pet dander triggers an asthma attack. This causes airway inflammation, constriction, and symptoms such as wheezing, coughing, chest tightness, and shortness of breath. Additionally, people with allergic asthma may experience itchy eyes and a runny nose due to related allergies.
Chronic Rhinosinusitis: Chronic rhinosinusitis is a persistent inflammation of the nasal passages and sinuses lasting 12 weeks or more, despite treatment. Symptoms include nasal congestion, thick discharge, facial pain, loss of smell, and coughing. This condition can be triggered by infections, nasal polyps, a deviated septum, and underlying health issues like asthma and allergies.
Chronic Spontaneous Urticaria (CSU): Chronic spontaneous urticaria (CSU) is characterized by recurring episodes of hives and/or angioedema, marked by itchy, raised, red welts and swelling under the skin. These symptoms occur frequently, often without a clear cause, and can significantly impact daily life. While the exact cause is unknown, CSU is often linked to autoimmune responses, where the immune system mistakenly attacks healthy tissue.

No, you must not stop or change the dose of your other asthma medicines unless your doctor specifically instructs you to. Omalizumab is designed to work alongside your current treatments, not replace them.
There is limited information on the safety of this medicine during pregnancy or breastfeeding. Talk to your doctor to weigh the benefits and potential risks before starting or continuing treatment.
This medicine specifically targets IgE, which is involved in allergic reactions, so it does not generally weaken your entire immune system. However, it may make it slightly harder for your body to fight certain parasite infections. Talk to your doctor if you have concerns.
If you miss a scheduled dose, contact your healthcare provider's office right away to reschedule your injection. Do not inject a double dose to make up for the missed one.
There is no direct chemical interaction between alcohol and Omalizumab. However, alcohol can be a trigger for asthma symptoms or hives in some individuals, so talk to your doctor or pharmacist for personalised advice.
