This medication is used to treat moderate to severe cases of plaque psoriasis. It works by blocking certain natural proteins in your body (interleukin-12 and interleukin-23) that may lead to the overproduction of skin cells and inflammation seen in plaque psoriasis.
Ustekinumab does not cure plaque psoriasis, but it can help lessen the symptoms, including decreasing the amount of painful, itchy, sore patches of thick, red or inflamed skin covered with silvery scales known as plaques. It is not known if using ustekinumab for more than 2 years is safe and effective.
Read the Medication Guide and the Instructions for Use provided by your pharmacist before you start using ustekinumab and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
Before starting this drug, you should take a tuberculosis (TB) skin test to check for a type of tuberculosis that may not be causing any symptoms (latent TB). If you are diagnosed with TB, to prevent a serious TB infection you must first be treated for it before you start ustekinumab.
This medication is given by injection under your skin either in the upper arms, buttock, thighs, or abdomen as directed by your doctor. You will receive one dose, followed by a second dose 4 weeks later. Then this medication is given every 3 months.
Dosage is based on your weight, medical condition, and response to treatment.
If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. Do not shake the solution.

It is important to change the location of the injection site with each dose to avoid problem areas under the skin. Therefore, choose a different injection site with each dose. Do not inject into skin that is irritated, sore, or infected.

Bruising, itching, pain, redness, swelling, or hardening of the skin at the injection site may occur. Injection site reactions usually go away after 1 or 2 days. Headache, back pain, or sinus/throat pain may also occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
