Daclizumab Injection


Daclizumab injection is used to prevent episodes of symptoms and slow the worsening of disability in people who have relapsing-remitting forms (course of disease where symptoms flare up from time to time) of multiple sclerosis (MS; a disease in which the nerves do not function properly and people may experience weakness, numbness, loss of muscle coordination, and problems with vision, speech, and bladder control). Daclizumab is usually used by people who were not helped by at least two other medications for MS. Daclizumab is in a class of medications called immunomodulators. It is thought to work by decreasing inflammation and decreasing the action of immune cells that may cause nerve damage.

Daclizumab Injection Dosage

Daclizumab comes as a solution (liquid) in a prefilled syringe to inject subcutaneously (under the skin). It is usually injected once a month. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use daclizumab exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

You will receive your first dose of daclizumab in your doctor’s office. After that, you can inject daclizumab yourself or have a friend or relative perform the injections. Before you use daclizumab yourself the first time, read the written instructions that come with it. Ask your doctor or pharmacist to show you or the person who will be injecting the medication how to inject it.

You can inject daclizumab in the back of your upper arms, stomach area, or your thighs. Do not inject your medication into skin that is irritated, bruised, reddened, infected, scarred, or tattooed.

Never reuse or share needles or prefilled syringes of medication. Throw away used syringes in a puncture-resistant container. Talk to your doctor or pharmacist about how to dispose of the puncture-resistant container.


Before having any laboratory test, tell your doctor and the laboratory personnel that you are using daclizumab injection.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
