Risk of serious infection

Using Skyrizi could raise your risk of getting a serious infection. This is because Skyrizi can weaken your immune system, which lowers your body’s defenses against infection.

Serious infections from Skyrizi are rare, but they can include:

  • cellulitis (bacterial skin infection)
  • osteomyelitis (bone infection)
  • sepsis (body’s extreme response to an infection that leads to organ damage)
  • shingles (a viral infection that often causes a painful rash)

Symptoms of an infection can include fever, tiredness, cough, or skin changes (warmth, pain, or pus).

What might help

To help prevent infection during your Skyrizi treatment, try to stay away from people who may be sick. Also, washing or sanitizing your hands often can help prevent the spread of infection.

If you notice symptoms of an infection during your treatment, call your doctor right away. They may want to do tests to find out what’s causing your infection. If needed, they may prescribe medications to treat your infection.

Keeping track of side effects

During your Skyrizi treatment, consider keeping notes on any side effects you’re having. You can share this information with your doctor. This is especially helpful to do when you first start taking new drugs or using a combination of treatments.
