Key takeaways
Taltz (ixekizumab) and Bimzelx (bimekizumab) are both medications used to treat moderate-to-severe plaque psoriasis, psoriatic arthritis, and other inflammatory conditions, and belong to the interleukin antagonist class. However, they have several differences. Taltz is typically injected once a month after initial doses, whereas Bimzelx starts with monthly injections and then shifts to every other month. Neither medication has a generic available. Common side effects of Taltz include upper respiratory infections and injection site reactions, while Bimzelx can cause upper respiratory infections and oral thrush, in addition to injection site reactions. Both medications can increase the risk of infections and should be used with caution regarding live vaccines.
