How should this medicine be used?

Sarilumab injection comes as a prefilled syringe and a prefilled pen to inject subcutaneously (under the skin). It is usually used once every 2 weeks. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use sarilumab injection 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 sarilumab injection in a doctor's office. After that, your doctor may decide that you or your caregiver can perform the injections at home. Your doctor will show you or the person who will be injecting the medication how to inject it. You or the person who will be injecting the medication should also read the written instructions for use that come with the medication. Be sure to ask your doctor or pharmacist if you have any questions about how to inject the medication.

Remove the prefilled syringe or prefilled pen from the refrigerator, place it on a flat surface, and allow it to reach room temperature (30 minutes for the prefilled syringe and 60 minutes for the prefilled pen) before your are ready to inject the medication. Do not try to warm the medication by heating it in a microwave, placing it in warm water or in direct sunlight, or through any other method. Do not remove the cover from the prefilled syringe or the cap from the prefilled pen while the medication is warming. You should remove the cover or cap just before you inject the medication.

Always look at sarilumab solution before injecting it. Check that the expiration date has not passed and that the liquid is clear and colorless to slightly yellow. The liquid should not contain visible particles. Do not use if it is expired or if the liquid is cloudy, discolored, or contains particles.

If another person is injecting your medication, the outer area of the upper arms also may be used. Do not inject the medication into skin that is tender, bruised, damaged, or scarred. Choose a different spot each time you inject the medication.

Use each syringe and pen only once. Throw away used syringes and pens in a puncture-resistant container. Talk to your doctor or pharmacist about how to dispose of thepuncture-resistant container.
