About Dupixent

What is Dupixent for?

Dupixent is used to treat adults and adolescents 12 years and older with moderate-to-severe atopic eczema (atopic dermatitis) who are candidates for systemic therapy. This medicine contains the active substance dupilumab.

Get the Facts

The active ingredient of Dupixent is dupilumab, a monoclonal antibody (a type of specialised protein) that blocks the action of proteins called IL-4 and IL-13. Both play a major role in causing the signs and symptoms of atopic dermatitis. This medicine may be used with atopic eczema medicines that you apply to the skin or it may be used on its own.

Using this medicine for atopic dermatitis can improve the condition of your skin and reduce itching. This medicine has also been shown to improve symptoms of pain, anxiety, and depression associated with moderate-to-severe atopic dermatitis. In addition, it may help improve your sleep disturbance and quality of life.

Pregnancy and breast-feeding
If you're pregnant, think you may be pregnant, or are planning to have a baby, ask your healthcare professional for advice before using this medicine. The effects of this medicine in pregnant women are not known; therefore, it is preferable to avoid the use of Dupixent in pregnancy unless your healthcare professional advises to use it.

Asthma
If you have asthma and are taking asthma medicines, do not change or stop your asthma medicine without talking to your healthcare professional.

Allergic reactions
Very rarely, Dupixent can cause serious side effects, including allergic (hypersensitivity) reactions. You must look out for signs of these conditions (such as fever, general ill feeling, swollen lymph nodes, hives, itching, joint pain, and skin rash) while you are taking this medicine. Stop using this medicine and tell your healthcare professional or get medical help immediately if you notice any signs of an allergic reaction.

Parasitic (intestinal parasites) infection
Dupixent may weaken your resistance to infections caused by parasites. If you already have a parasitic infection, it should be treated before you start treatment with this medicine. Check with your healthcare professional if you have diarrhea, gas, upset stomach, greasy stools, and dehydration which could be a sign of a parasitic infection. If you live in a region where these infections are common or if you are traveling to such a region, check with your healthcare professional.

Talk to your healthcare professional if you have any new or worsening eye problems, including eye pain or changes in vision.

Because of the chronic (recurring) nature of atopic dermatitis, the inflammation that causes your flare-ups may still be present beneath the surface of your skin, even if no flares are visible.
