ABOUT DUPIXENT

DUPIXENT, a biologic, is a type of medication that is processed in the body differently than oral or topical medications. In order to be effective and work properly, most biologics are injectable medicines.

DUPIXENT blocks the signaling of two key sources of Type 2 inflammation (IL-4 and IL-13). This inflammation is an important
component in the development of asthma, eczema, chronic rhinosinusitis with nasal polyposis, eosinophilic esophagitis, and
prurigo nodularis.

To learn more, explore our How DUPIXENT Works pages for your condition:

Do not use DUPIXENT if you are allergic to dupilumab or to any of the ingredients in DUPIXENT.

Before using DUPIXENT, tell your healthcare provider about all your medical conditions, including if you:

  • Have eye problems.
  • Have a parasitic (helminth) infection.
  • Are scheduled to receive any vaccinations. You should not receive a “live vaccine” right before and during treatment with
    DUPIXENT.
  • Are pregnant or plan to become pregnant. It is not known whether DUPIXENT will harm your unborn baby.
  • Are breastfeeding or plan to breastfeed. It is not known whether DUPIXENT passes into your breast milk.

Tell your healthcare provider about all of the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

Especially tell your healthcare provider if you are taking oral, topical, or inhaled corticosteroid medicines; have asthma and use an asthma medicine; or have atopic dermatitis, chronic rhinosinusitis with nasal polyposis, eosinophilic esophagitis, or prurigo nodularis and also have asthma. Do not change or stop your corticosteroid medicine or other asthma medicine without talking to your healthcare provider. This may cause other symptoms that were controlled by the corticosteroid medicine or other asthma medicine to come back.

DUPIXENT can cause serious side effects, including:

  • Allergic reactions. DUPIXENT can cause allergic reactions that can sometimes be severe. Stop using DUPIXENT and tell
    your healthcare provider or get emergency help right away if you get any of the following signs or symptoms:
  • breathing problems or wheezing
  • fast pulse
  • fever
  • general ill feeling
  • swollen lymph nodes
  • swelling of the face, mouth, tongue or throat
  • hives
  • itching
  • nausea or vomiting
  • fainting, dizziness, feeling lightheaded
  • joint pain
  • skin rash
  • cramps in your stomach-area
  • Eye problems. Tell your healthcare provider if you have any new or worsening eye problems, including eye pain or
    changes in vision, such as blurred vision. Your healthcare provider may send you to an ophthalmologist for an eye exam if
    needed.
  • Inflammation of your blood vessels. Rarely, this can happen in people with asthma who receive DUPIXENT. This may
    happen in people who also take a steroid medicine by mouth that is being stopped or the dose is being lowered. It is not
    known whether this is caused by DUPIXENT. Tell your healthcare provider right away if you have: rash, chest pain,
    worsening shortness of breath, a feeling of pins and needles or numbness of your arms or legs, or persistent fever.
  • Joint aches and pain. Joint aches and pain can happen in people who use DUPIXENT. Some people have had trouble
    walking or moving due to their joint symptoms, and in some cases needed to be hospitalized. Tell your healthcare provider
    about any new or worsening joint symptoms. Your healthcare provider may stop DUPIXENT if you develop joint symptoms.

The most common side effects of DUPIXENT include:

  • Eczema: injection site reactions, eye and eyelid inflammation, including redness, swelling, and itching, sometimes with
    blurred vision, dry eye, cold sores in your mouth or on your lips, and high count of a certain white blood cell (eosinophilia).
  • Asthma: injection site reactions, high count of a certain white blood cell (eosinophilia), pain in the throat (oropharyngeal
    pain), and parasitic (helminth) infections.
  • CRSwNP: injection site reactions, eye and eyelid inflammation, including redness, swelling, and itching, sometimes with
    blurred vision, high count of a certain white blood cell (eosinophilia), trouble sleeping (insomnia), toothache, gastritis and
    joint pain (arthralgia).
  • EoE: injection site reactions, upper respiratory tract infections, cold sores in your mouth or on your lips, and joint pain
    (arthralgia).
  • PN: eye and eyelid inflammation, including redness, swelling, and itching, sometimes with blurred vision, herpes virus
    infections, common cold symptoms (nasopharyngitis), dizziness, muscle pain, and diarrhea.

Tell your healthcare provider if you have any side effect that bothers you or that does not go away. These are not all of the
possible side effects of DUPIXENT. Call your doctor for medical advice about side effects. You are encouraged to report
negative side effects to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
