Effects of Drug Abuse

  • No information available

Short-Term Effects

  • See "What Are Side Effects Associated with Using Ixekizumab?"

Long-Term Effects

  • See "What Are Side Effects Associated with Using Ixekizumab?"

Cautions

  • Serious hypersensitivity reactions were reported, including angioedema and urticaria; anaphylaxis reported, some requiring hospitalization; if a serious hypersensitivity reaction occurs, discontinue the drug immediately and initiate appropriate therapy
  • Monitor for onset or exacerbation of Crohn’s disease and ulcerative colitis

Risk of infections

  • May increase risk of infection; upper respiratory tract infections, oral candidiasis, conjunctivitis, and tinea infections reported
  • Instruct patients to seek medical advice if signs or symptoms of infection occur
  • If a serious infection develops or infection is not responding to standard therapy, monitor the patient closely and discontinue therapy until the infection resolves

Tuberculosis evaluation

  • Evaluate patients for TB before initiating treatment
  • Do not administer to patients with active TB
  • Initiate treatment of latent TB before administering therapy
  • Consider anti-TB therapy before initiating in patients with a history of latent or active TB in whom an adequate course of treatment cannot be confirmed
  • Monitor closely for signs and symptoms of active TB during and after treatment

Drug interaction overview

  • Before initiating drug, consider completion of all age-appropriate immunizations; avoid the use of live vaccines; no data are available on the response to live vaccines while taking ixekizumab
  • Altering CYP450 enzymes
    • The formation of CYP450 enzymes can be altered by increased levels of certain cytokines (e.g., IL-1, IL-6, IL-10, TNF-alpha, IFN) during chronic inflammation; thus, ixekizumab, an IL-17A antagonist, could normalize the formation of CYP450 enzymes
    • Upon initiating or discontinuing ixekizumab in patients receiving concomitant CYP450 substrates, particularly those with a narrow therapeutic index, consider monitoring for effect (e.g., warfarin) or drug concentration (e.g., cyclosporine) and consider dosage modification of the CYP450 substrate

Pregnancy and Lactation

  • There are no available data regarding the use of ixekizumab in pregnant women to inform of any drug-associated risks. Human IgG is known to cross the placental barrier; therefore, ixekizumab may be transmitted from the mother to the developing fetus.
  • It is unknown if ixekizumab is distributed in human breast milk. Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for ixekizumab, and any potential adverse effects on the breastfed infant from ixekizumab or the underlying maternal condition.
