What Ixekizumab is and how it works

Uses, formulations, monitoring, and supply rules can differ by patient, product, and country. Follow the exact local product information and professional advice.

Mechanism of action: how Ixekizumab works

Ixekizumab is a humanized IgG4 monoclonal antibody that selectively binds to interleukin-17A (IL-17A), a pro-inflammatory cytokine involved in the pathogenesis of plaque psoriasis, psoriatic arthritis, and axial spondyloarthritis. By neutralizing IL-17A, ixekizumab inhibits its interaction with the IL-17 receptor, reducing inflammation and autoimmune activity. (1) (2)

Interactions

Medicine or testEffectAction
Recorded interactionsIxekizumab may interact with other immunosuppressive drugs and vaccines, especially live vaccines. Inform your healthcare provider about all medications and supplements you are taking. (1)

Pregnancy, breastfeeding, kidney/liver function, age

Pregnancy

There is a pregnancy exposure registry (1-800-284-1695). Animal reproduction studies showed no malformations, but neonatal deaths occurred at high maternal doses in monkeys; the clinical significance to humans is unknown. Discuss the risks and benefits with your healthcare provider if you are pregnant or planning pregnancy. (2)

Breastfeeding

Ixekizumab was detected in the milk of lactating monkeys in animal studies; there is no human lactation data. The developmental and health benefits of breastfeeding should be weighed against the mother's clinical need for treatment and any potential effects on the breastfed infant — a decision to make with your healthcare provider. (2)

Children

FDA-approved for plaque psoriasis in children aged 6 years and older, using a weight-based regimen: over 50 kg, 160 mg (two 80 mg injections) at Week 0 then 80 mg every 4 weeks; 25-50 kg, 80 mg at Week 0 then 40 mg every 4 weeks; under 25 kg, 40 mg at Week 0 then 20 mg every 4 weeks. NOTE: this corrects an earlier draft that said pediatric use was 'not recommended... safety not established,' which contradicted the record's own overview text about ages 6+. Ixekizumab is NOT approved in children for psoriatic arthritis, ankylosing spondylitis, or non-radiographic axial spondyloarthritis — those remain adults-only indications. (2)

Frequently asked questions

How quickly does ixekizumab work?

Many patients notice improvement in skin symptoms within 1 to 2 weeks, with maximum benefit typically seen after 12 weeks of treatment.

Can I use ixekizumab if I have an infection?

You should not start ixekizumab if you have an active infection. Inform your doctor if you develop signs of infection during treatment.

Is ixekizumab safe during pregnancy or breastfeeding?

There is a pregnancy exposure registry for TALTZ. Animal studies showed no birth defects but some neonatal deaths at high maternal doses in monkeys; human significance is unknown. Ixekizumab was detected in monkey milk with no human lactation data available. Discuss the risks and benefits with your doctor if you are pregnant, planning pregnancy, or breastfeeding.

Can I receive vaccines while on ixekizumab?

Avoid live vaccines during treatment. Inactivated vaccines may be given, but discuss with your healthcare provider.

What should I do if I miss a dose?

Are there any foods or drinks I should avoid?

There are no specific food or drink restrictions with ixekizumab. Maintain a healthy diet as advised by your healthcare provider.

How do I store ixekizumab at home?

What happens if I take too much Ixekizumab?

Overdosing on Ixekizumab is unlikely given its administration method. However, if an overdose is suspected, it is crucial to seek immediate medical attention or contact emergency services. Symptoms of an overdose are not well-defined, but close monitoring for adverse reactions and supportive care would be initiated by healthcare professionals.

Can I drink alcohol while taking Ixekizumab?

While there are no specific contraindications for alcohol consumption with Ixekizumab, it is generally advisable to limit or avoid alcohol. Alcohol can exacerbate certain inflammatory conditions that Ixekizumab treats and may also increase the risk of liver-related side effects, although this is less common with monoclonal antibodies. Always consult your healthcare provider for personalized advice.
