How should I use mirikizumab?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Before you use mirikizumab, your doctor may test you for tuberculosis or other infections.

For the first 3 doses, mirikizumab is injected into a vein by a healthcare provider every 4 weeks.

Later doses are then injected under the skin every 4 weeks. A healthcare provider may give you this injection or teach you how to properly use mirikizumab by yourself.

Your dose should be given as 2 injections under the skin to receive the full dose. Your healthcare provider will show you where to inject mirikizumab. Do not inject into the same place two times in a row. Do not give an injection into skin that is hard, red, bruised, or tender.

Do not shake the injection pen.

Ask your doctor or pharmacist if you don't understand how to use an injection pen.

Prepare an injection pen only when you are ready to give it. Call your pharmacist if the medicine looks cloudy, has changed colors or has particles in it.

Each injection pen is for one use only. Throw away after one use, even if there is still medicine left inside. Place them in a puncture-proof "sharps" container and dispose of it following state or local laws. Keep out of the reach of children and pets.

You may get infections more easily, even serious or fatal infections. You will need frequent medical tests.

You will need frequent blood tests to check your liver function.

Store the medicine in the original container in the refrigerator. Protect from light and do not freeze.

Take the medicine out of the refrigerator and let it reach room temperature for 30 minutes before using. Do not warm the medicine with hot water, sunlight, or a microwave.

Mirikizumab may also be stored in the original container at room temperature away from moisture, heat and light. Do not return the medicine to the refrigerator. Throw the medicine away after 2 weeks if stored at room temperature.
