Inclusion Criteria:

1. At least 18 years of age
2. At least one contact allergen with a 2+ (strong) or 3+ (extreme reaction) confirmed by patch testing within 6 months of the baseline visit that can be duplicated at the initiation of the study (placement at Week 0 and patch test reaction read at Week 0 +72-120 hours).
3. Allergic contact dermatitis diagnosed clinically by the principle investigators who have expertise in allergic contact dermatitis
4. Investigator's global assessment score of at least 3 (range 0-4) at the screening and baseline visits
5. Documented recent history (within 6 months of patch testing) of inadequate response to treatment with topical medications and allergen avoidance
6. Able and willing to provide informed consent, participate in study visits, and undergo visit procedures

Exclusion Criteria:

1. Prior dupilumab use
2. Treatment with a systemic immune-regulating medication within 3 months of the baseline visit or the patient's prior patch testing, whichever is longer. Examples of these medications include azathioprine, methotrexate, mycophenolate mofetil, Janus kinase inhibitors, and phototherapy (including tanning booths). Cyclosporine or prednisone may not have been used within 1 month of the baseline visit.
3. Treatment with other biologic agents, such as TNF inhibitors, anti-IL 17 agents, anti-IL 12/23 agents, or anti-IL 23 agents, within 4 months of baseline visit or the patient's prior patch testing, whichever is longer.
4. Use of rituximab within at 6 months (or until lymphocyte counts have normalized if longer than 6 months) of the baseline visit or the patient's prior patch testing, whichever is longer.
5. Treatment with topical corticosteroids or topical calcineurin inhibitors within 1 week before the baseline visit
6. Other active conditions, such as psoriasis, that may confound clinical evaluations of dermatitis and patient-reported symptoms
7. Increased risk of infection or reactivated infection, including history of human immunodeficiency virus, hepatitis B, hepatitis C, endoparasitic infections, receipt of a live attenuated vaccine within 3 months of the baseline visit, chronic or acute infection requiring treatment within 4 weeks of the baseline visit, immunosuppressed status (ie recurrent or resistant opportunistic infections)
8. Malignancy within 5 years of the screening visit excluding local cutaneous squamous cell carcinoma, basal cell carcinoma or cervical carcinoma in situ that has been fully treated.
9. Women who are or plan to become pregnant or breastfeed during study participation or are unable or not willing to use birth control during the study and for 4 months after the last dose of dupilumab. Options for birth control include abstinence, double barrier (ie male condom and female diaphragm), vasectomy, intrauterine device, and hormonal contraception. Females who have not had menses within 1 year of the baseline, bilateral tubal ligation, hysterectomy, and/or bilateral oophorectomy visit do not require additional methods contraception during study participation.
10. Unstable condition or status, as per study investigator's judgment, that may lead to more likely discontinuation from the study including but not limited to major, recurrent medical illnesses that may require hospital admission and/or discontinuation of dupilumab, surgery that would require discontinuation of dupilumab and/or major rehabilitation, inability to participate in all study visits and administer dupilumab
