Key takeaways
Cosentyx (secukinumab) and Taltz (ixekizumab) are both injectable medications used to treat inflammatory conditions like plaque psoriasis and psoriatic arthritis. They belong to the same drug class, interleukin antagonists, and work by blocking interleukin-17 (IL-17) to reduce inflammation. However, there are some differences between them. Cosentyx is also approved for conditions like hidradenitis suppurativa and enthesitis-related arthritis, while Taltz is not. Cosentyx can be used in children as young as 2 years old for certain conditions, whereas Taltz is generally for adults and children 6 years and older. Cosentyx is typically injected once a month after initial doses, and it can be given as an infusion in a clinic, while Taltz is injected every 4 weeks after initial doses. Both medications can cause side effects like upper respiratory infections, but Taltz is more likely to cause injection site reactions. Neither medication has a generic version available, and both can increase the risk of infections, so you should be cautious about getting vaccines while using them.
