Ixekizumab (Taltz) is a biologic medication used to treat psoriatic arthritis, plaque psoriasis, ankylosing spondylitis, and non-radiographic axial spondyloarthritis. Biologic medications are proteins designed by humans that affect the immune system. Ixekizumab blocks the inflammatory protein IL-17A. This improves joint pain and swelling from arthritis and rash in psoriatic conditions.
Ixekizumab can lower the ability of your immune system to fight infections. If you develop symptoms of an infection while using this medication, you should stop it and contact your rheumatology provider. All patients should be tested for tuberculosis and hepatitis before starting on Ixekizumab. The most common side effects are infections, injection site reactions, upper respiratory infections, and lowering of white blood cells called neutropenia. Rare cases of inflammatory bowel disease (Crohn’s disease or ulcerative colitis) have been seen. Ixekizumab has not been studied in pregnancy or breastfeeding.
You should contact your provider if you develop symptoms of an infection, such as a fever or cough, or if you think you are having any side effects, especially diarrhea or allergic reactions. Be sure to let your s know if you are pregnant, planning to get pregnant, or if you are breastfeeding. If you are planning on having surgery or if you plan on getting any live vaccinations, talk to your rheumatology provider first. These include the nasal spray flu vaccine, and others such as the measles, mumps, rubella, and yellow fever vaccines.
