- A serious and rare condition that affects the brain. This condition is referred to as reversible posterior leukoencephalopathy syndrome (RPLS): The cause of RPLS is not known. If RPLS is found early and treated, most people recover. Tell your healthcare provider right away if you notice:
- vision problems
- Serious Infections: Ustekinumab may lower the ability of your immune system to fight infections and may increase your risk of infections. Some people have serious infections while taking Stelara, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses. Some people have to be hospitalized for treatment of their infection.
- Your doctor should check you for TB before starting ustekinumab.
- If your doctor feels that you are at risk for TB, you may be treated with medicine for TB before you begin treatment with ustekinumab and during treatment with ustekinumab.
- Your doctor should watch you closely for signs and symptoms of TB during treatment with ustekinumab.
- You should not start taking ustekinumab if you have any kind of infection unless your doctor says it is okay.
Before starting ustekinumab, tell your doctor if you think you have an infection or have symptoms of an infection such as:
- fever, sweats, or chills
- muscle aches
- shortness of breath
- blood in your phlegm
- weight loss
- warm, red, or painful skin or sores on your body
- diarrhea or stomach pain
- burning when you urinate or urinate more often than normal
- feel very tired
- are being treated for an infection
- get a lot of infections or have infections that keep coming back

After starting ustekinumab, call your doctor right away if you have any symptoms of an infection (see above).
Ustekinumab can make you more likely to get infections or make an infection that you have worse.
People who have a genetic problem where the body does not make any of the proteins interleukin 12 (IL-12) and interleukin 23 (IL-23) are at a higher risk for certain serious infections. These infections can spread throughout the body and cause death. It is not known if people who take ustekinumab will get any of these infections, because of the effects of ustekinumab on these proteins in your body.
