Ixekizumab — Uses, Dosage, Side Effects & Safety

Drug class: Monoclonal Antibody (Anti-IL-17A)

Overview

Ixekizumab is a prescription medicine used to treat adults and children (aged 6 years and older) with moderate to severe plaque psoriasis, active psoriatic arthritis, and ankylosing spondylitis (axial spondyloarthritis). It works by targeting and blocking interleukin-17A (IL-17A), a protein in the immune system that contributes to inflammation and the development of these autoimmune conditions. By reducing inflammation, ixekizumab helps improve skin symptoms, joint pain, and stiffness. Patients often notice clearer skin and less joint discomfort after regular use. It is given as an injection under the skin, usually every 2 to 4 weeks, depending on the condition being treated. Key points for patients: Ixekizumab is not a cure, but it can significantly reduce symptoms and improve quality of life. It may lower your immune system’s ability to fight infections, so regular monitoring and communication with your healthcare provider are important.
