1. What Dupixent is and what it is used for

What Dupixent is

Dupixent contains the active substance dupilumab.

Dupilumab is a monoclonal antibody (a type of specialised protein) that blocks the action of proteins called interleukins (IL)-4 and IL-13. Both play a key role in the development of signs and symptoms of atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), nodular prurigo (NP), eosinophilic esophagitis (EoE), chronic obstructive pulmonary disease (COPD), and chronic spontaneous urticaria (CSU).

What it is used for

Dupixent is used to treat adults and adolescents aged 12 years and older with moderate-to-severe atopic dermatitis, also known as atopic eczema. Dupixent is also used to treat children aged 6 months to 11 years with severe atopic dermatitis. Dupixent may be used together with eczema medications applied to the skin or may be used alone.

Dupixent is also used, together with other asthma medications, for the maintenance treatment of severe asthma in adults, adolescents, and children aged 6 years and older whose asthma is not controlled with their current medication (e.g., corticosteroids).

Dupixent is also used, together with other medications, for the maintenance treatment of CRSwNP in adults whose disease is not controlled with their current CRSwNP medication. Dupixent may also reduce the need for surgery and the need for systemic corticosteroids.

Dupixent is also used to treat adults with moderate-to-severe nodular prurigo (NP), also known as chronic nodular prurigo (CNP). Dupixent may be used together with NP medications applied to the skin or may be used alone.

Dupixent is also used to treat adults, adolescents, and children aged 1 year and older, with a minimum body weight of 15 kg, with eosinophilic esophagitis (EoE).

Dupixent is also used, together with other medications, for the maintenance treatment of chronic obstructive pulmonary disease (COPD) in adults with uncontrolled COPD.

Dupixent is also used to treat adults, adolescents, and children aged 2 years and older with moderate-to-severe chronic spontaneous urticaria (CSU) not controlled with antihistamines, who have not received immunoglobulin E (IgE) blockers for their CSU.

How Dupixent works

Using Dupixent for atopic dermatitis (atopic eczema) may improve your skin condition and reduce itching. Dupixent has also shown improvement in pain, anxiety, and depression symptoms associated with atopic dermatitis. In addition, Dupixent helps improve sleep disturbances and overall quality of life.

Dupixent helps prevent severe asthma attacks (exacerbations) and may improve your breathing ability. Dupixent may also help reduce the amount of another group of medications you need to control your asthma, called oral corticosteroids, while preventing severe asthma attacks and improving your breathing ability.

Dupixent helps prevent moderate or severe COPD flare-ups (exacerbations) and may improve your breathing ability. Dupixent may also help improve general COPD symptoms.

Using Dupixent for CSU may improve your skin condition by reducing itching and hives.

2. What you need to know before using Dupixent

Do not use Dupixent

  • if you are allergic to dupilumab or to any of the other ingredients of this medicine (listed in section 6).

If you think you may be allergic, or are unsure, consult your doctor, pharmacist, or nurse before using Dupixent.

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before starting to use Dupixent:

Dupixent is not a rescue medicine and should not be used to treat a sudden asthma or COPD attack.

Each time you receive a new pack of Dupixent, it is important to record the name of the medicine, the date of administration, and the batch number (found on the pack after "Batch") and keep this information in a safe place.

Allergic reactions

  • Rarely, Dupixent may cause serious adverse effects, including allergic reactions (hypersensitivity), anaphylactic reaction, and angioedema. These reactions may occur from minutes after administration of Dupixent up to seven days later. While using Dupixent, you should monitor for signs of these conditions (i.e., breathing difficulties, swelling of the face, lips, mouth, throat, or tongue, fainting, dizziness, lightheadedness (low blood pressure), fever, general feeling of being unwell, swollen lymph nodes, hives, itching, joint pain, skin rash). These signs are listed under "Serious adverse effects" in section 4.
  • Stop using Dupixent and tell your doctor or seek immediate medical help if you notice any signs of an allergic reaction.

Eosinophilic conditions

  • Rarely, patients taking medication for asthma may develop inflammation of blood vessels or lungs due to an increase in a certain type of white blood cells (eosinophilia).
  • It is not known whether this is caused by Dupixent. This usually, but not always, occurs in people who are also taking a steroid medicine that has been stopped or whose dose is being reduced.
  • If you experience a combination of symptoms including flu-like illness, tingling or numbness in arms or legs, worsening of lung symptoms and/or rash, inform your doctor immediately.

Parasitic infection (intestinal parasites)

  • Dupixent may weaken your resistance to infections caused by parasites. If you already have a parasitic infection, it should be treated before starting treatment with Dupixent.
  • Consult your doctor if you have diarrhea, gas, stomach discomfort, greasy stools, or dehydration, which may be signs of a parasitic infection.
  • If you live in or are traveling to an area where such infections are common, consult your doctor.

Asthma
If you have asthma and are taking asthma medication, do not change or stop taking your asthma medication without consulting your doctor. Talk to your doctor before stopping treatment with Dupixent or if your asthma is not controlled or worsens during treatment with this medicine.

Eye problems

Talk to your doctor if you develop eye problems or if existing eye problems worsen, including eye pain or changes in vision.
