HOW should this medicine be used?
Ustekinumab injection products come as a solution (liquid) in single-dose, prefilled syringes and single-dose vials, to inject subcutaneously (under the skin) or intravenously (into a vein). For the treatment of plaque psoriasis and psoriatic arthritis, ustekinumab injection products are usually injected subcutaneously every 4 weeks for the first two doses and then every 12 weeks for as long as treatment continues. For the treatment of Crohn's disease and ulcerative colitis, ustekinumab injection products (Stelara, Wezlana) are usually injected intravenously for the first dose and then given subcutaneously every 8 weeks for as long as treatment continues.
You will receive your first subcutaneous dose of ustekinumab injection products in your doctor's office. After that, your doctor may continue to give you injections or allow you to inject ustekinumab injection products yourself or have a caregiver perform the injections. Ask your doctor or pharmacist to show you or the person who will be performing the injections how to inject ustekinumab products. Before you use ustekinumab injection products yourself the first time, read the written instructions that come with the product.
If your medication comes in a prefilled syringe or vial, use each syringe or vial only once and inject all the solution in the syringe. Even if there is still some solution left in the syringe or device, do not use it again. Dispose of used needles, syringes, and devices in a puncture-resistant container. Talk to your doctor or pharmacist about how to dispose of the puncture-resistant container.
Do not shake a prefilled syringe or vial that contains ustekinumab injection products.
Always look at ustekinumab injection solution before injecting it. Check that the expiration date has not passed and that the liquid is clear or slightly yellow. The liquid may contain a few visible white particles. Do not use the vial or prefilled syringe if it is damaged, expired, frozen, or if the liquid is cloudy or contains large particles.
You can inject ustekinumab injection products subcutaneously anywhere on the front of your thighs (upper leg), buttocks, or abdomen (stomach) except your navel and the area 2 inches (5 centimeters) around it. If another person is injecting your medication, the outer area of the upper arms also may be used. To reduce the chances of soreness or redness, use a different site for each injection. Do not inject into an area where the skin is tender, bruised, red, or hard or where you have scars or stretch marks.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with ustekinumab injection products. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (https://www.fda.gov/Drugs/DrugSafety/ucm085729.htmhttps://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
