Additional Relevant Details US FDA has approved Taltz (ixekizumab) injection 80 mg/mL for the treatment of moderate-to-severe plaque psoriasis in adult patients who are candidates for systemic therapy or phototherapy. Taltz should not be used in patients with a previous hypersensitivity reaction, such as anaphylaxis, to ixekizumab or to any of the excipients. Taltz is designed to specifically target IL-17A, a protein that plays a role in driving underlying inflammation in psoriasis.
