Ixekizumab (Taltz)

medicine injection

Ixekizumab (Taltz) is a biologic medication used to treat psoriatic arthritis and plaque psoriasis. 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 from psoriasis.

How to Take It

Ixekizumab is a self-administered injection that comes in 80 mg syringes. For psoriatic arthritis, it starts with 160 mg (2 syringes), followed by 80 mg (1 syringe) every 4 weeks. For plaque psoriasis, it starts with 160 mg (2 syringes), followed by 80 mg (1 syringe) at weeks 2, 4, 6, 8, 10, and 12, then every 4 weeks. The medicine can be injected into the thigh or abdomen. The site of injection should be rotated so the same site is not used multiple times. Some patients will start to see improvement within a few weeks, but it may take several months to take full effect. Ixekizumab may be taken alone or with methotrexate or other non-biologic drugs. Ixekizumab should not be given in combination with another biologic drug.

Side Effects

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 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.

Tell Your Rheumatology Provider

You should contact your rheumatology 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 provider know if you are pregnant, planning to get pregnant, or are breastfeeding. If you are planning to have surgery or get any live vaccinations, talk to your rheumatology provider first. These include the shingles vaccine, nasal spray flu vaccine, and others such as the measles, mumps, rubella, and yellow fever vaccines.
