How should I use ustekinumab?
Before you start treatment with ustekinumab, your doctor may perform tests to make sure you do not have tuberculosis or other infections.
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed. You must remain under the care of a doctor while you are receiving ustekinumab.
Ustekinumab is injected under the skin, or as an infusion into a vein, usually once every 12 weeks. Your first and second dose may be only 4 weeks apart.
A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself. Read and carefully follow any Instructions for Use provided with your medicine. Do not use ustekinumab if you don't understand all instructions for proper use. Ask your doctor or pharmacist if you have questions.
Prepare your injection only when you are ready to give it. Do not use if the medicine looks cloudy, has changed colors, or has particles in it. Call your pharmacist for new medicine.
Your care provider will show you the best places on your body to inject ustekinumab. Use a different place each time you give an injection. Do not inject into the same place two times in a row. Avoid injecting the medicine into skin that is red, bruised, swollen, or tender.
Ustekinumab doses are based on weight. Your dose needs may change if you gain or lose weight.
Call your doctor if you have any signs of tuberculosis: fever, cough, night sweats, loss of appetite, weight loss, and feeling constantly tired.
You will need frequent medical tests.
Each prefilled syringe or single-use vial (bottle) is for one use only. Throw it away after one use, even if there is still medicine left inside.
Store in the refrigerator. Protect from light. Do not freeze and not shake the medicine. Store ustekinumab vials in an upright position.
Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.
What happens if I miss a dose?
Call your doctor for instructions if you miss a dose.
What happens if I overdose?

What should I avoid while using ustekinumab?
Avoid being near people who are sick or have infections. Tell your doctor at once if you develop signs of infection.

Live vaccines include measles, mumps, rubella (MMR), rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.
BCG vaccine should not be given for at least 1 year after you receive your last dose of ustekinumab.
