  • Dupixent And Cancer: In recent years, however, Dupixent® has been linked to cutaneous T-cell lymphoma (CTCL), a rare and serious form of non-Hodgkin lymphoma. Studies published in 2024 and 2025 suggest that Dupixent® patients may face a 300% higher risk of developing CTCL yet manufacturers never warned healthcare providers or patients about this risk.

  2. Red, scaly, or thickened patches of skin
  3. Peeling skin
  4. Discolored skin
  5. Raised bumps or nodules
  6. Skin sores or ulcers
  7. Hair loss
  8. Enlarged lymph nodes

Key Warning Signs for Dupixent and Cancer

Severe Eczema Patients Be Vigilant: For individuals using Dupixent for severe eczema, the diagnostic challenge is compounded because the drug’s anti-inflammatory action may temporarily mask or alter the appearance of early CTCL symptoms.

    • Failure to respond to treatment: Rashes or lesions that persist, worsen, or spread despite ongoing Dupixent use should raise suspicion of an underlying condition.
    • Progression to plaques and tumors: The development of thicker, raised lesions (plaques) or lumps/nodules (tumors) that can ulcerate is a sign of advancing CTCL not typically seen in standard eczema.
    • Development of systemic symptoms: Advanced CTCL can lead to symptoms not associated with eczema, such as persistently swollen lymph nodes (in the neck, armpits, or groin), unexplained fatigue, or weight loss.

Skin Changes and Seeking Immediate Medical Help: If you notice persistent or unusual skin changes while on Dupixent, it is crucial to seek a medical evaluation, including a skin biopsy reviewed by a specialist familiar with cutaneous lymphomas

Scientific Evidence and Regulatory Action Regarding Dupixent and Cancer

Scientific studies and reports to the FDA have highlighted a potential link between Dupixent and T-cell lymphomas:
  • FDA Investigation: The FDA is formally investigating the potential safety signal for CTCL linked to Dupixent use. This investigation began in March 2025.
    • Status: The FDA has not recalled Dupixent, but the investigation is formal and follows a pattern of regulatory actions that may include label revisions.
  • Increased Risk Studies: Several peer-reviewed studies suggest an increased risk of Dupixent and Cancer.
