What is Dupixent?

Dupixent (dupilumab) is a biologic that is given by subcutaneous (under the skin) injection that may be used to treat the following inflammatory conditions:

Moderate to severe atopic dermatitis (eczema) in adults and children 6 months and older whose condition is not well controlled with topical prescription therapies or who cannot use topical therapies. Dupixent can be used with or without topical corticosteroids
Moderate-to-severe eosinophilic or oral-corticosteroid-dependent asthma in adults and children who are at least 6 years old as add-on maintenance treatment. It is used to treat acute bronchospasm or status asthmaticus
Inadequately controlled chronic rhinosinusitis (a long-standing inflammation of the sinuses) that is associated with nasal polyps, as an add-on maintenance treatment in adults
Eosinophilic esophagitis in adults and children 1 year of age and older, who weigh at least 33 pounds (15 kg)
Prurigo nodularis in adults.

Dupixent works by targeting and binding to a protein that is associated with inflammation called interleukin-4 (IL-4) receptor alpha subunit (IL-4Ra)], preventing IL-4 and IL-3 signaling. This inhibits the inflammatory response including the release of proinflammatory cytokines, chemokines, nitric oxide, and IgE. Dupixent is an interleukin-4 receptor alpha antagonist.

Dupixent was first FDA-approved on March 28, 2017.

Warnings

Hypersensitivity reactions including anaphylaxis, serum sickness, angioedema, urticaria, rash, erythema nodosum, and erythema multiforme have been reported with Dupixent. Do not use Dupixent if you are allergic to dupilumab or any of the ingredients. Stop Dupixent immediately and contact your healthcare provider if you develop any allergy symptoms.

May cause conjunctivitis and keratitis. Report new onset or worsening eye symptoms to your healthcare provider. Your healthcare provider may suggest an ophthalmological examination.

May increase the risk of developing eosinophilic conditions. Tell your doctor if you develop a red or purple rash, shortness of breath, or tingling or nerve pain in your hands or feet.

Your healthcare provider will decide if you need to continue with oral, topical, or inhaled corticosteroids while being treated with Dupixent. These should be reduced gradually, do not discontinue without your doctor’s advice.

Report new onset or worsening joint pain or swelling to your healthcare provider. Further investigation may be required.

Any pre-existing worm or parasitic (helminth) infections should be treated before initiating Dupixent. If patients become infected during treatment and do not respond to antihelminths, then discontinue Dupixent until the infection resolves.

Avoid the use of live vaccines. May reduce the immune response to other vaccinations.

It is not known if Dupixent is safe and effective for children with:

atopic dermatitis under 6 months of age
asthma under 6 years of age
chronic rhinosinusitis with nasal polyposis under 18 years of age

How should I use Dupixent?

Use Dupixent exactly as prescribed by your doctor. Follow all directions on your Dupixent label and package insert.

Dupixent is not a rescue medicine for asthma attacks. Use only fast-acting inhalation medicine for an attack.

Seek medical attention if your breathing problems get worse quickly, or if you think your asthma medications are not working as well.

A healthcare provider may teach you how to properly use the medication by yourself. Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all the instructions.

Dupixent is injected under the skin, usually once every 2 to 4 weeks. Your first dose may be given in 2 injections.
Take a syringe or pen out of the refrigerator and let it reach room temperature for 30 to 45 minutes before injecting your dose. Leave the needle cap on until you are ready to inject your dose.
Do not shake the prefilled syringe or injection pen. Prepare your injection only when you are ready to give it.
Do not use it if the medicine looks cloudy, has changed colors, or has particles in it. Call your pharmacist for new medicine.
The pre-filled pen is for use in adults and children 2 years and older. The pre-filled syringe is for use in adults and children 6 months and older.
The Dupixent prefilled pen or syringe may be injected under the skin of your upper thigh or stomach area (except for the 2 inches [5 cm]) around your belly button (navel). Caregivers may also inject it in the outer area of the upper arm.
Choose a different site for each injection. Do not inject into skin that is tender, damaged, has bruises or scars, or into areas with visible veins. Do not inject through clothes.
Each prefilled syringe or injection pen is for one use only. Throw it away after one use, even if there is still medicine left inside.

This drug can be used with or without topical corticosteroids. Topical calcineurin inhibitors may be used but should be reserved for problem areas only (e.g., face, neck, intertriginous, and genital areas).

What happens if I miss a dose?

If you miss your injection by 7 days or less, use the missed dose as soon as you remember and then start a new every-week dose schedule from the time you remember.

If your dose schedule is every other week and you miss a dose of Dupixent give the injection within 7 days from the missed dose, then continue with your original schedule. If the missed dose is not given within 7 days, wait until the next scheduled dose to give your injection.

If your dose schedule is every 4 weeks and you miss a dose of Dupixent, give the injection within 7 days from the missed dose, then continue with your original schedule. If the missed dose is not given within 7 days, start a new every 4-week dose schedule from the time you remember to take your injection.

Do not use two doses at one time.

What happens if I overdose?

If you inject too much Dupixent, call your healthcare provider or Poison Help line at 1-800-222-1222 or go to the nearest hospital emergency room right away.

Popular FAQ

How fast does Dupixent work?

Dupixent can start to work in 2 to 4 weeks to relieve your symptoms of moderate-to-severe eczema, asthma, or chronic rhinosinusitis with nasal polyps. In studies of eosinophilic esophagitis, improved inflammation, swallowing or other symptoms was seen in at 24 weeks In patients 12 years and older and at 16 weeks in 1 to 11 years olds. For adults with prurigo nodularis, improved itching was seen at 12 and 24 weeks, and reduced skin lesions (clear or almost clear skin) at 24 weeks. Continue reading

Why does it cause eye problems?

Dupixent is associated with several different eye problems, including conjunctivitis, blepharitis, dry eyes, itchy eyes, and keratitis. The cause of the eye problems is thought to be due to Dupixent blocking interleukin-13 (IL-13), an inflammatory protein that also stimulates the production of goblet cells. Goblet cells are responsible for creating mucus in the eye and ensuring the stability of tears. So when Dupixent blocks IL-13 it also lowers the numbers of epithelial goblet cells leading to eye inflammation and eye problems. Continue reading

Is this an immunosuppressant?

No, Dupixent (dupilumab) is not an immunosuppressant or a steroid. Dupixent works by targeting a type of protein called an interleukin, that is involved in inflammation. Dupixent calms an overreactive immune system but does not suppress the immune system. This leads to fewer and less severe episodes of inflammation when used to treat conditions such as atopic dermatitis or asthma. Continue reading

Does it cause weight gain?

Yes, it does appear that Dupixent can cause weight gain, although this is not listed as a side effect in the product information. A case series of 12 people prescribed Dupixent reported an average weight gain of 6.1kg over one year – the amount of weight gained ranged from 0.1kg to 18.0kg. Anecdotally, blog sites also report weight gain as a side effect. How Dupixent causes weight gain is not known; however, people should be informed that weight gain may be a possible side effect of Dupixent. Continue reading

How long can Dupixent stay out of the fridge?

Dupixent can stay out of the fridge for a maximum of 14 days at room temperature (up to 77°F [25°C]). If you do not use it within 14 days, then it must be thrown away. Do not expose Dupixent to temperatures above 77°F and do not put it back in the refrigerator if it has been inadvertently left out and allowed to warm up to room temperature. Continue reading

Can it cure eczema?

Dupixent is not a cure for eczema; however, it does effectively reduce symptoms in the majority of people prescribed it. Dupixent significantly reduces itching, skin appearance, the frequency of AD flares, sleep, and quality of life in most people.
