Patient information: uses, side effects, how to take - Dupixent
What is DUPIXENT?
DUPIXENT is a prescription medicine used:
- to treat adults and children 6 months of age and older with moderate-to-severe eczema (atopic dermatitis or AD) that is not well controlled with prescription therapies used on the skin (topical), or who cannot use topical therapies. DUPIXENT can be used with or without topical corticosteroids.
- with other asthma medicines for the maintenance treatment of moderate-to-severe asthma in adults and children 6 years of age and older whose asthma is not controlled with their current asthma medicines. DUPIXENT helps prevent severe asthma attacks (exacerbations) and can improve your breathing. DUPIXENT may also help reduce the amount of oral corticosteroids you need while preventing severe asthma attacks and improving your breathing.
- with other medicines for the maintenance treatment of chronic rhinosinusitis with nasal polyps (CRSwNP) in adults and children 12 years of age and older whose disease is not controlled.
- to treat adults and children 1 year of age and older with eosinophilic esophagitis (EoE), who weigh at least 33 pounds (15 kg).
- to treat adults with prurigo nodularis (PN).
- with other medicines for the maintenance treatment of adults with inadequately controlled chronic obstructive pulmonary disease (COPD) and a high number of blood eosinophils (a type of white blood cell that may contribute to your COPD). DUPIXENT is used to reduce the number of flare-ups (the worsening of your COPD symptoms for several days) and can improve your breathing.
- to treat adults and children 2 years of age and older with chronic spontaneous urticaria (CSU), who continue to have hives that are not controlled with H1 antihistamine treatment.
- to treat adults with bullous pemphigoid (BP).
- to treat adults and children 6 years of age and older with allergic fungal rhinosinusitis (AFRS) who have had surgery on their nose or sinuses in the past.
DUPIXENT is not used to relieve sudden breathing problems and will not replace an inhaled rescue medicine or to treat any other forms of hives (urticaria).
DUPIXENT works by blocking two proteins that contribute to a type of inflammation that plays a major role in AD, asthma, CRSwNP, EoE, PN, COPD, CSU, BP, and AFRS.
It is not known if DUPIXENT is safe and effective in children with:
- AD under 6 months of age.
- Asthma under 6 years of age.
- CRSwNP under 12 years of age.
- EoE under 1 year of age, or who weigh less than 33 pounds (15 kg).
- PN under 18 years of age.
- COPD under 18 years of age. COPD is most often seen in adults.
- CSU under 2 years of age, or who weigh less than 11 pounds (5 kg).
- BP under 18 years of age. BP is most often seen in adults.
- AFRS under 6 years of age.
Do not use DUPIXENT if you are allergic to dupilumab or to any of the ingredients in DUPIXENT. See the end of this Patient Information leaflet for a complete list of 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.
Pregnancy Exposure Registry. There is a pregnancy exposure registry for women who use DUPIXENT during pregnancy. The purpose of this registry is to collect information about the health of you and your 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
- have AD, CRSwNP, EoE, PN, COPD, CSU, BP, or AFRS, and also have asthma
Do not change or stop your other medicines, including corticosteroid medicine or other asthma medicine, without talking to your healthcare provider. This may cause other symptoms that were controlled by those medicines to come back.
How should I use DUPIXENT?
- See the detailed "Instructions for Use" that comes with DUPIXENT for information on how to prepare and inject DUPIXENT and how to properly store and throw away (dispose of) used DUPIXENT pre-filled syringes and pre-filled pens.
