Taltz (ixekizumab) is a prescription biologic medication approved to treat several chronic inflammatory conditions. As a targeted therapy, it helps manage moderate-to-severe plaque psoriasis, psoriatic arthritis, ankylosing spondylitis, and nonradiographic axial spondyloarthritis. Administered via subcutaneous injection, Taltz works by inhibiting specific proteins in the immune system that trigger inflammation.
What is Taltz and How Does It Work?
Taltz contains the active ingredient ixekizumab, a biologic drug designed to target and block interleukin-17A (IL-17A). This specific protein plays a key role in the inflammatory response. In people with psoriasis and certain types of arthritis, the immune system produces too much IL-17A, leading to skin plaques, joint pain, swelling, and stiffness. By blocking this protein, Taltz helps reduce inflammation, clear skin lesions, and prevent joint damage.
Approved Uses for Taltz
Taltz is prescribed for adults and children under specific guidelines. It is approved for moderate-to-severe plaque psoriasis in adults and children aged six and older who are candidates for systemic therapy or phototherapy. Additionally, adults can use Taltz to treat active psoriatic arthritis, ankylosing spondylitis, and active nonradiographic axial spondyloarthritis showing signs of inflammation.
Understanding Taltz Dosages
Taltz is available as a liquid solution in single-dose prefilled syringes and autoinjectors. The standard dosing regimen typically begins with a loading dose, which consists of a higher initial dose administered as two injections. For plaque psoriasis, this is followed by injections every two weeks for the first twelve weeks, transitioning to a maintenance dose once every four weeks. For other arthritic conditions, maintenance doses are generally administered every four weeks.
Potential Side Effects and Risks
Like all biologic medications, Taltz can cause side effects. The most common mild reactions include injection site soreness, redness, nausea, and mild upper respiratory or fungal infections. Because Taltz suppresses part of the immune system, it can increase the risk of serious infections, including tuberculosis. Patients should be tested for tuberculosis before starting treatment. Other rare but serious risks include the development or worsening of inflammatory bowel disease and severe allergic reactions.
Storage and Administration Guidelines
Taltz must be stored in the refrigerator between 36 degrees and 46 degrees Fahrenheit and kept in its original carton to protect it from light. Before injection, the medication should be allowed to reach room temperature for at least thirty minutes. If necessary, Taltz can be kept at room temperature up to 86 degrees Fahrenheit for up to five days, but it must be discarded if not used within this timeframe.
