Emicizumab
About Emicizumab
This injection is used regularly as a long-term preventive treatment. To get the best results, you must inject it consistently on your scheduled days, even if you do not feel any symptoms of bleeding. While this medicine works internally to help your blood clot, maintaining a healthy weight and staying active can support your joint health.
Most people tolerate this medication well, but you may experience redness, itching, or pain at the injection site, as well as headaches or joint pain. If you experience severe symptoms like sudden pain, swelling in your arms or legs, numbness, or breathing difficulties, you must contact your doctor immediately.
Before starting this medication, tell your healthcare provider if you have any other health conditions or allergies. Do not take this if you have had a severe allergic reaction to this medication or any of its ingredients in the past. Always talk to your doctor or pharmacist to ensure this treatment is safe for your specific health profile.
This medication can interact seriously with certain other clotting therapies, which can increase your risk of developing dangerous blood clots. If you are pregnant, planning to become pregnant, breastfeeding, or are an older adult, talk to your doctor to understand the risks and benefits before starting treatment.

View AllDrug Warnings
- Check the solution before injecting: Inspect the liquid in the vial. It should be clear to slightly yellowish. Do not use it if it is cloudy, contains visible particles, or looks discoloured.
- Rotate your injection sites: Use a different spot for each injection (stomach, thigh, or upper arm) to keep your skin healthy and reduce irritation.
- Avoid certain rescue therapies: Talk to your doctor about what rescue medicines to use if you experience a breakthrough bleed. Avoid using activated prothrombin complex concentrate (aPCC) while taking Emicizumab unless specifically directed, as this combination can cause dangerous blood clots.
- Keep a treatment log: Write down the date, time, and injection site for every dose to help track your treatment compliance and share this with your healthcare team.
- Do not rub the injection site: After injecting, you can press a clean cotton ball or gauze gently on the site if needed, but do not rub it, as this can increase irritation.
Drug Interactions
- Activated prothrombin complex concentrate (aPCC): Combining this rescue treatment with Emicizumab can lead to severe, life-threatening blood clots or damage to small blood vessels. Avoid using these together unless strictly monitored by your specialist.
- Factor VIII concentrates: While these are generally safer than aPCC to use for breakthrough bleeding, they should still be used cautiously under your doctor’s guidance.

Patients Concern
Disease/Condition Glossary
Hemophilia A: Hemophilia A is a genetic disorder caused by a deficiency or absence of factor VIII, a protein essential for blood clotting, resulting in difficulty forming blood clots and an increased risk of prolonged bleeding. This condition is commonly treated with clotting factor replacement therapy.
FAQs
Emicizumab belongs to the group of medications called Monoclonal antibodies used to prevent or reduce bleeding episodes in individuals with haemophilia A, a genetic bleeding disorder caused by a clotting factor VIII deficiency.
Emicizumab contains Emicizumab. It replicates the function of factor VIII, a crucial protein for blood clotting. It connects activated factor IX and factor X, promoting effective clot formation in individuals with hemophilia A. This process helps prevent and minimize bleeding episodes, including in patients with factor VIII inhibitors.
