What is Dupixent (Dupilumab)?
Dupixent is an anti-inflammatory medication developed by Sanofi and Regeneron. It is a type of drug called a monoclonal antibody, which is made in a laboratory to target specific parts of the immune system. Biologic drugs like Dupixent are medications made from living cells that target specific parts of the immune system to help control disease processes.
What is Dupixent Used For?
Doctors prescribe Dupixent to treat several chronic inflammatory conditions, including:
- Moderate to severe atopic dermatitis (eczema)
- Chronic sinusitis
- Asthma
- Chronic rhinosinusitis with nasal polyps
- Eosinophilic esophagitis
- Prurigo nodularis,
- Chronic obstructive pulmonary disease (eosinophilic type)
- Chronic spontaneous urticaria
- Bullous pemphigoid
How Does Dupixent Work?
Dupixent works by blocking two proteins in the immune system, called interleukin-4 (IL-4) and interleukin-13 (IL-13). These proteins play a key role in causing inflammation in the body. By stopping their activity, Dupixent helps reduce inflammation and improve symptoms linked to certain chronic conditions.
Common Dupixent Side Effects
Like most prescription medications, Dupixent can cause side effects. Some of the more common side effects include:
- Injection site reactions, such as redness, swelling, or pain
- Eye problems, including redness, itching, or swelling
- Cold sores on the lips or mouth
- Sore throat or runny nose
If you notice side effects that bother you or do not go away, talk to your doctor. They can help you decide whether to continue treatment or explore other options.
What Are the Worst Side Effects of Dupixent?
In rare cases, Dupixent has been linked to more serious side effects. Dupixent changes how the immune system responds in different areas of the body. This is done by blocking certain proteins that drive inflammation. In rare situations, this altered response may uncover hidden conditions like cutaneous T-cell lymphoma or contribute to other serious immune-related problems.
Can Dupixent Cause Lymphoma?
Recent research suggests Dupixent is linked to a higher risk of cutaneous T-cell lymphoma (CTCL), a rare but aggressive form of non-Hodgkin lymphoma. CTCL begins in certain white blood cells, called T-cells, and primarily affects the skin. While Dupixent does not directly cause cancer, some studies of asthma and atopic dermatitis patients suggest that its effect on the immune system may uncover or accelerate certain types of lymphoma. This is especially true in patients who were already at risk of CTCL.
Cutaneous T-Cell Lymphoma (CTCL) Symptoms
Doctors look for several warning signs when diagnosing cutaneous T-cell lymphoma (CTCL). Common symptoms include:
- Scaly patches of skin that may thicken or change over time
- Persistent itching that does not improve with standard treatments
- Swollen lymph nodes in the neck, armpits, or groin
- Skin tumors or nodules that develop as the disease progresses
- Fatigue or a general feeling of being unwell
- Unexplained weight loss
It’s important to note that some of the symptoms of cutaneous T-cell lymphoma closely resemble eczema symptoms. Studies have shown that Dupixent use can “uncover” or worsen hidden lymphomas mistaken for eczema. If you take Dupixent for eczema, and you experience one or more of these symptoms or worsening symptoms, contact your doctor. As the condition worsens, it can spread to the internal organs and can even lead to blood cancers.
Are Asthma Patients Using Dupixent At Risk for Lymphoma?
Yes, asthma patients taking Dupixent face a heightened risk of developing lymphoma, according to recent data. A large population-based cohort of adults with asthma found that Dupixent use was associated with an increased risk of T-cell and NK-cell lymphomas. Further testing is needed to determine the exact cause, but it’s important for asthma patients to monitor their symptoms while taking Dupixent.
Why is the Dupixent Manufacturer Being Sued?
Patients and families have begun filing lawsuits against Dupixent’s manufacturers, claiming the companies failed to adequately warn patients about the risk of cutaneous T-cell lymphoma (CTCL). While Dupixent has helped many people manage chronic inflammatory conditions, reports of patients developing CTCL compared to those not taking Dupixent have raised concerns.
Lawsuits argue that the manufacturers knew or should have known about these risks based on clinical trials, case reports, and adverse event signals. However, the companies did not provide clear warnings to doctors and patients. In fact, as of September 2025, cutaneous T-cell lymphoma is not listed as a potential adverse reaction to the medication.
In product liability law, a drugmaker can be held responsible if it fails to warn users of known or reasonably discoverable dangers. If a court finds that Sanofi and Regeneron failed to disclose the potential for Dupixent to unmask or accelerate CTCL, they could be liable for damages.
2025 Dupixent Class Action Lawsuit News
As of September 2025, there is no class action lawsuit against the manufacturers of Dupixent related to an increased risk of developing CTCL. Product liability claims against Dupixent manufacturers are still in the very early stages, and only individuals have filed lawsuits. However, over the next year, the number of lawsuits may grow and may be consolidated into a multidistrict litigation (MDL).
If you are investigating Dupixent lawsuits and believe you may be eligible to file a claim, contact Lipton Law today. We can file a lawsuit on your behalf and can keep you up-to-date on any news related to Dupixent lymphoma lawsuits.
Am I Eligible for a Dupixent Lawsuit?
You may be eligible to file a Dupixent lawsuit against the drug manufacturers if:
- You used Dupixent as prescribed
- You were diagnosed with T-cell lymphoma, including cutaneous T-cell lymphoma (CTCL)
- You experienced serious side effects or worsening symptoms of Dupixent or CTCL
- You’re within the Michigan statute of limitations for product liability claims (3 years)
Patients diagnosed with CTCL after taking Dupixent may be eligible for compensation.
Can I Sue for Misdiagnosis of Lymphoma?
Yes, if you received a delayed diagnosis of T-cell lymphoma, or if your doctor failed to diagnose you with T-cell lymphoma, you may be able to sue. Skin cancer is a very commonly misdiagnosed type of cancer, due to the fact that skin cancer can look a lot like other, non-cancerous skin conditions. In fact, the skin symptoms of cutaneous T-cell lymphoma often mimic those of moderate to severe eczema.
This is why people taking Dupixent for eczema are at an increased risk of skin cancer misdiagnosis. Doctors may ignore the early warning signs of CTCL in patients with pre-existing skin symptoms like skin plaques or persistent itching.
It’s important for doctors to properly screen their patients with eczema for CTCL and provide a correct and prompt cancer diagnosis. When healthcare providers dismiss the early signs of T-cell lymphoma, the patient loses precious time that could be spent treating their condition and preventing it from worsening.
At Lipton Law, our MI skin cancer misdiagnosis attorneys understand how devastating it is when a cancer diagnosis comes too late. If you or a loved one has had their CTCL misdiagnosed or missed by a medical professional, call our firm today. We can evaluate your case and help determine your eligibility for a claim.

- Medical expenses
- Lost wages
- Future medical treatment
- Pain and suffering
- Permanent disfigurement
- Loss of enjoyment of life
