Taltz (ixekizumab) is a specialist biologic injection, on the market since about 2016, that blocks IL-17A (an immune signal that drives inflammation) to treat moderate-to-severe plaque psoriasis from age 6 and, in adults, psoriatic arthritis and inflammatory spinal arthritis such as ankylosing spondylitis, usually once creams or older treatments fall short. Most people tolerate it well, and what they notice most is redness or stinging at the injection site, more colds, and occasionally thrush (a mouth yeast infection). The one thing to watch is infection, because Taltz dampens part of your immune defenses, so expect a tuberculosis test before starting and report fever or a lasting cough.
Clinical pearls
- Let the autoinjector sit out of the fridge about 30 minutes with the cap on, since a room-temperature dose usually stings less.
- Get any needed vaccines before starting, because live vaccines, such as the nasal spray flu vaccine, must be avoided while on Taltz.
- Report new belly pain, diarrhea or bloody stool promptly, since Taltz can trigger or worsen Crohn's disease or ulcerative colitis.
- Rotate between thigh, belly and upper arm, and flag any new eczema-like rash that appears after starting.

What Ixekizumab Injection is used for
▾
Ixekizumab injection is a targeted biologic approved to treat several immune-driven inflammatory conditions.
- Taltz treats moderate-to-severe plaque psoriasis in patients 6 years of age and older who are candidates for systemic therapy or phototherapy
- Taltz treats active psoriatic arthritis in adults — it may be used alone or with a conventional DMARD such as methotrexate; patients who also have moderate-to-severe plaque psoriasis follow the adult psoriasis dosing schedule
- Taltz treats active ankylosing spondylitis in adults
- Taltz treats active non-radiographic axial spondyloarthritis (nr-axSpA) — a form of spinal inflammatory arthritis that doesn't show bone damage on X-rays but has measurable signs of inflammation — in adults
How Ixekizumab Injection works
▾
Ixekizumab is a humanized monoclonal antibody — an engineered protein that precisely targets a single immune messenger called interleukin-17A (IL-17A). IL-17A is naturally produced during immune responses, but in conditions like psoriasis and inflammatory arthritis, it's overactive — driving the redness, scaling, and joint inflammation those diseases are known for. By binding tightly to IL-17A and blocking it from activating its receptor, ixekizumab quiets this overactive signal and reduces the release of other pro-inflammatory chemicals (cytokines and chemokines).
Ixekizumab Injection dosage
▾
Taltz is given as a subcutaneous injection (under the skin) and is not taken by mouth. The injection schedule varies by condition — most regimens begin with a higher starting dose, then shift to a maintenance dose given every 4 weeks. For pediatric plaque psoriasis, the dose is also adjusted by the child's weight. For non-radiographic axial spondyloarthritis, Taltz is given once every 4 weeks without an initial higher starting dose.
- Rotate injection sites each time (thigh, abdomen, or upper arm) and avoid skin that is tender, bruised, or affected by psoriasis
- Let Taltz warm to room temperature for 30 minutes before injecting; keep the needle cap on during warming
- If a dose is missed, take it as soon as you remember, then return to your regular schedule
- Food does not affect subcutaneous injections — there are no food-related timing restrictions

More serious reactions — including severe allergic responses (anaphylaxis), serious infections, severe eczema-like skin eruptions, and new or worsening inflammatory bowel disease — require prompt medical attention and may mean stopping Taltz.
Ixekizumab Injection warnings and precautions
▾
- Serious infections: Taltz lowers immune defenses. Serious bacterial, viral, and fungal infections have been reported. Tell your doctor right away if you develop a fever, chills, persistent cough, or any sign of infection that isn't getting better.
- Tuberculosis (TB): You must be screened for TB before starting Taltz. Active TB is a contraindication; latent (dormant) TB must be treated first. Stay alert for TB symptoms — lasting cough, night sweats, weight loss — throughout treatment.
- Serious allergic reactions: Anaphylaxis and other severe hypersensitivity reactions have occurred. Seek emergency care immediately if you have trouble breathing, throat swelling, or a sudden severe rash.
- Eczematous eruptions: Some people develop severe eczema-like skin reactions after starting Taltz — sometimes needing hospitalization. These can appear days to months after the first dose. Tell your doctor about any new or worsening skin changes.
- Inflammatory bowel disease: Crohn's disease and ulcerative colitis have occurred or worsened in people taking Taltz. Report ongoing stomach pain, diarrhea, or blood in your stool.
- Live vaccines: Avoid live vaccines while on Taltz. Complete recommended vaccinations before starting treatment.
Ixekizumab Injection interactions
▾
The FDA label for Taltz does not detail specific drug-drug interactions, but there are important precautions related to other treatments:
- Live vaccines — must be avoided while taking Taltz, as the reduced immune response could make live vaccines unsafe or ineffective; complete all age-appropriate vaccines before starting
- Conventional DMARDs (e.g., methotrexate) — Taltz may be used alongside these for psoriatic arthritis, as directed by your prescriber
Not a complete list. The label covers the interactions the manufacturer studied or reported, and our own interaction database does not cover every medicine either. Bring your full medication list, including vitamins and herbal products, to your pharmacist.
Before taking Ixekizumab Injection
▾
- Active serious hypersensitivity to ixekizumab or any ingredient in Taltz — this is a contraindication; do not use Taltz if you've had a severe allergic reaction to it before
- Active or latent TB — must be evaluated and, if needed, treated before starting Taltz
- Ongoing or recurring infections — tell your doctor about any current infections or a history of frequent infections
- Inflammatory bowel disease — Crohn's disease or ulcerative colitis may worsen; discuss with your doctor
- Pregnancy — data are insufficient to confirm safety; the drug may cross the placenta. A pregnancy registry (1-800-284-1695) is available for women who use Taltz while pregnant
- Breastfeeding — it is unknown whether ixekizumab passes into human milk; discuss benefits and risks with your doctor
- Children under 6 — safety and effectiveness have not been established in this age group
- Adults 65 and older — no meaningful differences in safety or effectiveness have been observed, but limited data are available
How your body processes Ixekizumab Injection
▾
After a subcutaneous injection, ixekizumab is absorbed gradually — peak blood levels are reached in about 4 days. Injecting into the thigh achieves slightly higher absorption compared to the arm or abdomen. Bioavailability (the amount that actually reaches the bloodstream) ranges from about 60% to 81%.
The drug has a half-life of about 13 days, meaning it takes roughly two weeks for half of a dose to clear from the body. It is broken down through the body's normal protein recycling pathways — not processed by the liver enzymes that handle most oral medications. Body weight affects how quickly ixekizumab is cleared, with higher body weight leading to faster clearance. Age does not significantly affect how the drug is processed in adults.
How to store Ixekizumab Injection
▾
Store refrigerated at 2°C to 8°C (36°F to 46°F). store TALTZ at room temperature up to 30°C (86°F) for up to 5 days in the original carton to protect from light. stored at room temperature, do not return to the refrigerator and discard, if unused, within 5 days.

Ixekizumab Injection side effects reported to the FDA (FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Ixekizumab Injection — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Ixekizumab Injection in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.
