About Dupixent

Dupixent is used with other asthma medicines for the maintenance treatment of severe asthma in adults and adolescents (aged 12 and older) whose asthma is not controlled with their current asthma medicines. This medicine contains the active substance dupilumab.

Get the Facts

Dupixent is a monoclonal antibody (a type of specialised protein) that blocks the action of two proteins called Interleukin 4 (IL-4) and Interleukin 13 (IL-13). IL-4 and IL-13 can trigger signals that lead to lung inflammation, causing the symptoms of asthma. Dupixent helps prevent severe asthma attacks (exacerbation) and can improve your son or daughter’s breathing.

Dupixent is not a rescue medicine and should not be used to treat a sudden asthma attack. Remember to not change or stop other asthma medicines without talking to your son or daughter’s healthcare professional.

Get the Facts
Keep this medicine out of the sight and reach of children.

Do not use this medicine after the expiry date that is stated on the label and carton after EXP. The expiry date refers to the last day of that month. Store in a refrigerator (2°C to 8°C). Pre-filled syringes or pens may be kept at room temperature for a maximum of 14 days. Do not store above 25°C. Do not freeze. Store in the original carton to protect from light. Do not use this medicine if you notice that the medicine is cloudy, discoloured, or has particles in it.

Precautions
Do not use Dupixent if your son or daughter is, or you think is, allergic to dupilumab or any of the other ingredients of this medicine. If you think your son or daughter may be allergic, or you are not sure, ask your healthcare professional for advice before using this medicine.

Pregnancy and breast-feeding
If your daughter is pregnant, thinks she may be pregnant, or is 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. If she is planning to breast-feed, your healthcare professional should decide if she will breast-feed or use this medicine. She should not do both.

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 breathing problems, swelling of the face, mouth and tongue, fainting, dizziness, feeling lightheaded (low blood pressure), fever, general ill feeling, swollen lymph nodes, hives, itching, joint pain, skin rash while you are taking this medicine. Stop using this medicine and tell your son or daughter’s healthcare professional or get medical help immediately if you notice any signs of an allergic reaction. These reactions can occur from minutes up to seven days after Dupixent administration.

Eosinophilic conditions
Rarely patients taking an asthma medicine may develop inflammation of blood vessels or lungs due to an increase of certain white blood cells (eosinophilia). Tell your doctor immediately if your son or daughter develops a combination of symptoms such as flu-like illness, pins and needles or numbness of the arms or legs, worsening of pulmonary symptoms, and/or rash.

Parasitic (intestinal parasites) infection
Dupixent may weaken your son or daughter’s resistance to infections caused by parasites. If your son or daughter already has a parasitic infection, it should be treated before starting treatment with this medicine. Check with your healthcare professional if your son or daughter has diarrhoea, 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 and your son or daughter are travelling to such a region, check with your healthcare professional.

Eye problems
Talk to your healthcare professional if your son or daughter has any new or worsening eye problems, including eye pain or changes in vision.

Vaccinations
Talk to your healthcare professional if your son or daughter has recently had or is due to have a vaccination.

Please refer to the Patient Information Leaflet in the pack for full safety information.

Dosing

Dupixent is given by injection under the skin. Your healthcare professional decides if your son or daughter should inject this medicine or if you should do it. Always use this medicine exactly as your healthcare professional has explained.

Inject this medicine only after your son, daughter or you have been trained by your healthcare professional

You and your son or daughter can inject into your son or daughter’s thigh or belly (stomach), except for the 5 cm around the navel. You can also use your son or daughter’s upper arm if you are doing the injection. Change the injection site for each injection. Do not inject into skin that is tender, damaged or has bruises or scars. Ensure you have the following: the Dupixent pre-filled syringe or pen, 1 alcohol wipe, 1 cotton ball or gauze, and a puncture resistant container. Please follow all instructions outlined in the Instructions for Use in the Dupixent pack and ask your healthcare professional if you have any questions.

Your healthcare professional will decide how much Dupixent your son or daughter needs and for how long. The recommended dose of Dupixent for adults and adolescents (12 years of age and older) is:

  • An initial dose of 400 mg (two 200 mg injections), followed by 200 mg every other week administered as subcutaneous injection.
  • For patients with severe asthma and who are on oral corticosteroids or for patients with severe asthma and comorbid moderate-to-severe atopic dermatitis or adults with co-morbid severe chronic rhinosinusitis with nasal polyposis, the recommended dose is an initial dose of 600 mg (two 300 mg injections), followed by 300 mg every other week administered as subcutaneous injection.

Because of the chronic (recurring) nature of the disease, the inflammation that causes your son or daughter’s symptoms of asthma may still be present even if there is no asthma exacerbation. So you should continue to inject Dupixent as prescribed, even if your son or daughter’s breathing improves, to continue the clinical benefits of the medicine.

  • Liquid prescription medications are exempt from the onboard liquid restrictions in some countries, but you will still need to declare them during security screening.
