Important Safety Information

STELARA^® is a prescription medicine that affects your immune system. STELARA^® can increase your chance of having serious side effects including:

Serious Infections STELARA^® may lower your ability to fight infections and may increase your risk of infections. While taking STELARA^®, some people have serious infections, which may require hospitalization, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses.

• Your doctor should check you for TB before starting STELARA^® and watch you closely for signs and symptoms of TB during treatment with STELARA^®.
• If your doctor feels that you are at risk for TB, you may be treated for TB before and during treatment with STELARA^®.

You should not start taking STELARA^® if you have any kind of infection unless your doctor says it is okay.  Before starting STELARA, tell your doctor if you think you have an infection or have symptoms of an infection such as:

• fever, sweats, or chills
• muscle aches
• cough
• 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
• have TB, or have been in close contact with someone who has TB

After starting STELARA, call your doctor right away if you have any symptoms of an infection (see above).
STELARA^® 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 that can spread throughout the body and cause death. It is not known if people who take STELARA^® will get any of these infections because of the effects of STELARA^® on these proteins.

Cancer STELARA^® may decrease the activity of your immune system and increase your risk for certain types of cancer. Tell your doctor if you have ever had any type of cancer.

Reversible posterior leukoencephalopathy syndrome (RPLS) RPLS is a rare condition that affects the brain and can cause death. The cause of RPLS is not known. If RPLS is found early and treated, most people recover. Tell your doctor right away if you have any new or worsening medical problems including: headache, seizures, confusion, and vision problems.  RPLS Info (Not: this can also be caused by cyclosporine and tacrolimus,which is a cream that used in treating pyroderma.  I am currently on cyclosporine and have used tacrolimus since 09, but currently off this treatment.) 

Serious Allergic Reactions Serious allergic reactions can occur. Get medical help right away if you have any symptoms such as: feeling faint, swelling of your face, eyelids, tongue, or throat, trouble breathing, throat or chest tightness, or skin rash.
