Omalizumab is a sophisticated, DNA-derived monoclonal antibody. It works by specifically binding to free human immunoglobulin E (IgE) in the blood and interstitial fluid. By doing so, it prevents IgE from attaching to the high-affinity receptors on the surface of mast cells and basophils. This action "blocks" the allergic cascade before it starts, significantly reducing the release of inflammatory mediators like histamine and leukotrienes that cause severe asthma attacks and chronic hives.
In Nigeria, Omalizumab 150mg (available as Xolair by Novartis) is a premier clinical choice for patients with difficult-to-treat allergic conditions. It is available through specialized cold-chain pharmacies like Sanlive Pharmacy to ensure patients receive authentic, temperature-controlled vials. The "Cold Chain" Rule: Omalizumab is a delicate protein; it must be stored in a refrigerator (2°C to 8°C) and transported in a validated cool bag to maintain its life-saving potency.
Important: This is a high-precision biological medication. The "Anaphylaxis" Warning: In rare cases, Omalizumab can cause a severe allergic reaction (anaphylaxis), which may occur hours or even days after the injection. You must be monitored by a healthcare professional for at least 30 to 60 minutes after every dose. The "Wait" Rule: This is not a "rescue" inhaler; it takes several weeks to reach its full effect. The "Professional" Rule: This must be administered via subcutaneous (SC) injection by a trained medical professional in a facility equipped to handle emergencies.
Omalizumab 150mg Injections are primarily used to:
Treat Moderate-to-Severe Persistent Asthma in patients with a positive skin test or in vitro reactivity to a perennial aeroallergen
Reduce the frequency of Asthma Exacerbations (attacks) and hospitalizations
Treat Chronic Spontaneous Urticaria (CSU)—hives that persist for 6 weeks or more despite antihistamine use
Manage Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) in adults
Help prevent severe reactions in people with IgE-Mediated Food Allergies (under specialist guidance)
Allow for a reduction in the use of oral corticosteroids (steroid-sparing effect)
Improve overall lung function and quality of life for patients with severe allergies
This product is suitable for:
Adults and children (6 years and older) with severe allergic asthma not controlled by high-dose inhalers
Patients with chronic hives who have not responded to maximum doses of antihistamines
Individuals requiring a targeted, "biologic" approach to systemic allergic inflammation
Not recommended for: Treating acute bronchospasm or status asthmaticus (it is a preventative, not a rescue drug). It is strictly contraindicated for individuals with a known hypersensitivity to Omalizumab or any of its ingredients. Use with caution in patients with a high risk of parasitic (helminth) infections, as IgE helps fight parasites. Consult our pharmacist if you are taking other "biologic" medications. Consult your doctor if you are pregnant; it should only be used if the clinical benefit justifies the risk to the fetus.
Administer exactly as prescribed; the dose is calculated based on body weight and baseline Total IgE levels.
Dosing Schedule: Depending on your IgE levels, you may receive 150mg to 600mg every 2 or 4 weeks.
The "Cold" Tip: The vial should be removed from the refrigerator and allowed to reach room temperature (about 20 minutes) before the clinician prepares the injection.
Injection Site: Injected under the skin (Subcutaneous) in the upper arm, thigh, or abdomen.
Consistency is Vital: Missing a dose can cause your "free IgE" levels to rise again, leading to a return of severe symptoms.
The "Duration" Rule: For asthma, your doctor will usually evaluate the effectiveness after 16 weeks of consistent treatment.
If a dose is missed, contact your specialist immediately to reschedule your clinic visit.
Omalizumab is effective, but because it modifies the immune system, some individuals may experience:
Pain, redness, or swelling at the injection site (most common)
Headache or dizziness
Joint pain (Arthralgia) or muscle aches
Fatigue or "flu-like" symptoms
Rare but serious: Anaphylaxis (shortness of breath, hives, swelling of the throat)
Rare: A temporary drop in blood platelet counts
Rare: Fever, rash, and joint pain occurring a few days after injection (Serum Sickness-like reaction)
Seek immediate emergency medical attention if you experience sudden difficulty breathing, swelling of the tongue/throat, fainting, or a widespread itchy rash after your injection.

Can I stop using my asthma inhalers once I start Xolair?
No. You must continue all your current medications exactly as prescribed. Xolair is an "add-on" therapy. Over time, if your asthma stays well-controlled, your doctor may slowly reduce your other medicines.
How long does it stay in my system?
Omalizumab has a long half-life (about 26 days). This is why it is usually injected only once or twice a month. It takes time to "clear" the IgE out of your blood.
Does the injection hurt?
Like most subcutaneous shots, there is a small sting, but the volume is small. Because the liquid is thick, the clinician will inject it slowly to ensure it is comfortable.
Where can I purchase Omalizumab 150mg in Nigeria?
You can find premium, cold-chain verified Omalizumab at Sanlive Pharmacy & Stores for guaranteed product integrity and professional immunology support.
