01What should I know about ustekinumab before using it?

Do not use ustekinumab unless it has been prescribed to you by a healthcare provider. Use it as prescribed. Do not share ustekinumab with other people, even if they have the same condition as you. It may harm them. Keep ustekinumab out of the reach of children. Since this medicine should be kept in a refrigerator, take special precautions to keep it away from children who also use the refrigerator. This medicine is injected. Make sure that you or a caregiver understands how to properly prepare and use ustekinumab. If you have any questions, talk to your healthcare provider. The needle cover of the prefilled syringe contains dry natural rubber, which is made from latex. This may cause an allergic reaction if you are sensitive to latex. Inject ustekinumab into a different site each time. Avoid injecting ustekinumab into skin that is bruised, hard, red, or tender. Avoid injecting into moles or scars. Ustekinumab can increase the risk of skin cancer. If you need to be in sunlight, wear sunscreen, a hat, and clothing that covers your skin.

02Should you avoid sun exposure during Stelara treatment?

Yes. Your doctor may recommend limiting your sun exposure during Stelara treatment due to the risk of skin cancer. This may be especially important if you have risk factors for this condition, such as if you have a personal or family history of skin cancer. Immunosuppressants such as Stelara are known to increase the risk of cancer. Since Stelara was approved for use, there have been reports of nonmelanoma skin cancer by people who had skin cancer risk factors while receiving this medication. Be sure to have regular skin cancer screenings, and talk with your doctor or a dermatologist to learn more.
