Idacio (Adalimumab-Aacf) for Psoriasis and Psoriatic Arthritis

Idacio (adalimumab-aacf) is a prescription medication approved by the U.S. Food and Drug Administration (FDA) to treat adults with moderate to severe chronic plaque psoriasis and active psoriatic arthritis.

How Idacio Works and How It’s Taken

Idacio is a type of medication called a tumor necrosis factor (TNF) blocker. It works by binding to TNF-alpha, a protein involved in inflammation. By blocking TNF-alpha, Idacio helps reduce inflammation. In people with plaque psoriasis, treatment may reduce skin thickening and the buildup of inflammatory cells in the skin.

Doctors prescribe Idacio for adults with moderate to severe chronic plaque psoriasis. It is used for people who may need treatment that works throughout the body or light therapy, when other treatments are less appropriate.

Idacio is a biosimilar to Humira (adalimumab). This means it is made from living cells and is designed to work like the original medicine. The FDA requires biosimilars to have no meaningful differences in safety or how well they work.

Idacio is given as an injection under the skin. With proper training and a doctor’s guidance, people or caregivers may give the injections at home.

Typical Dosing for Psoriasis

The recommended starting dose of Idacio for psoriasis is 80 milligrams as an initial dose.

One week later, treatment continues with 40 milligrams every other week.

This information is based on the prescribing information, but your healthcare provider may tailor your treatment plan. Always follow their guidance.

Idacio Side Effects

In clinical studies of Idacio for moderate to severe chronic plaque psoriasis in adults, the most common side effects occurred in at least 10 percent of people. These side effects were:

Infections, such as upper respiratory infections and sinus infections
Injection site reactions, such as redness or skin discoloration, itching, bleeding, pain, or swelling where the shot is given
Headache
Rash

Serious Side Effects and Warnings

Idacio can cause serious side effects that may require immediate medical attention. These include:

Serious infections — Because Idacio affects the immune system, infections can become severe, including tuberculosis (TB) and invasive fungal infections.
Malignancies — These can include lymphoma and other cancers.
Hypersensitivity reactions — Severe allergic reactions such as anaphylaxis or angioedema can occur.
Hepatitis B virus (HBV) reactivation — HBV can become active again in people who carry it.
Nervous system problems — Rare demyelinating disorders, such as optic neuritis or Guillain-Barré syndrome, can occur.
Blood problems — Rare but serious low blood cell counts, which can lead to easy bruising, bleeding, or persistent fever, can occur.
New or worsening heart failure — The heart may not pump as well, leading to symptoms like shortness of breath or swelling.
Immune system reactions — These reactions can include lupuslike syndrome or autoimmune hepatitis, where the immune system attacks the body.

Get medical help right away if you think you are having a serious reaction.

Should I take Idacio for psoriasis or psoriatic arthritis if I have an infection?

Idacio should not be started if you have an active infection, including a localized infection. This medicine can lower your immune system’s ability to fight infections and can raise the risk of serious infections, including TB, fungal infections, and other bacterial or viral infections. Contact your doctor if you develop signs or symptoms of infection during treatment.
