Can Immunotherapy Cause Neuropathy, and How Can Patients Cope?

Short answer: Yes, some immunotherapy drugs can affect the nerves and lead to neuropathy (numbness, tingling, burning pain, weakness), although this is relatively uncommon compared with classic chemotherapy causes. Symptoms often improve by pausing treatment and starting anti‑inflammatory therapy, and there are practical steps and medications that can help you cope. ^[1] [PM9]

What is neuropathy from cancer therapies?

Neuropathy means nerve damage that leads to symptoms like tingling, numbness, burning pain, balance problems, or weakness, typically starting in the fingers and toes and sometimes progressing in a “glove and stocking” pattern. Cancer treatments can inflame or injure peripheral nerves, causing sensory, motor, or cranial nerve problems; onset can be sudden or gradual. ^{[2] [3]}

Can immunotherapy cause neuropathy?

• Yes, immune checkpoint inhibitors (ICIs) can cause neurological immune‑related adverse events, including peripheral neuropathies, though they are rare compared with other side effects. [PM9]
• These events often arise within the first 3 months of starting immunotherapy, progress subacutely, and require early recognition. [PM7]
• Newer immunotherapies and antibody–drug conjugates have been associated with peripheral neuropathy as well, in addition to traditional agents like taxanes, platins, vinca alkaloids, and proteasome inhibitors. ^[1]
• Neuropathy from immunotherapy may present as numbness/tingling in hands and feet, pain, or difficulty walking, and your team may offer symptom‑relief medicines. ^{[4] [5] [6]}

How common is it?

• Neurologic irAEs with ICI monotherapy affect roughly ~1% of patients, and 2–3% with combination therapy, spanning neuropathies, myositis, and other conditions; most improve with prompt treatment. [PM9]
• While exact neuropathy rates vary by drug and regimen, the risk is real but generally low compared to chemo‑induced neuropathy. [PM8] [PM11]

Typical timing and course

• Usually begins within 3 months of initiation of immunotherapy, with faster progression than idiopathic autoimmune diseases. [PM7]
• Symptoms often improve after holding the immunotherapy and starting corticosteroids, though some cases need additional immunomodulatory therapies. [PM11] [PM9]

When to contact your care team

Call promptly if you notice:

• New or worsening numbness, tingling, burning, or pain in hands/feet. ^{[4] [5]}
• Weakness, trouble walking, falls, or difficulty feeling the ground. ^{[4] [5]}
• Facial weakness, trouble speaking or swallowing, or double vision, which can signal cranial nerve involvement or overlap syndromes needing urgent attention. Early diagnosis and treatment are essential. [PM7] [PM9]

Medical management

• Hold or pause the immunotherapy for moderate to severe symptoms; mild symptoms may be monitored while continuing treatment. [PM7]
• Start glucocorticoids (e.g., prednisolone 1–2 mg/kg/day) for markedly affected patients, which often leads to improvement. [PM7]
• Escalate to intravenous immunoglobulin (IVIg) or plasma exchange if symptoms are severe or steroid‑refractory, sometimes alongside other immunosuppressants. [PM10] [PM11]
• Decisions about re‑challenging immunotherapy depend on severity and recovery and are best made by a multidisciplinary team. [PM7] [PM11]

Practical coping strategies

• Stay active: Gentle, regular exercise improves circulation, balance, and mood; a physical therapist can tailor safe routines. ^[5]
• Protect your feet and hands: Wear supportive, cushioned shoes; check skin daily to prevent unnoticed injuries if sensation is reduced. ^[7]
• Fall prevention: Use night lights, remove loose rugs, and consider balance training; ask about assistive devices if needed. ^[7]
• Manage discomfort: Your team may suggest medications for nerve pain (for example, duloxetine, gabapentin, or pregabalin), topical agents, or compounded creams. These can ease symptoms while definitive treatment (like steroids) works. [PM11]
• Lifestyle tips: Stop smoking, keep blood sugar controlled if you have diabetes, and avoid excessive alcohol, all of which can worsen nerve health. ^[5]
• Skin and nail care: Moisturize, avoid extreme hot/cold on numb areas, and clip nails carefully to reduce injury risk. ^[7]
• Mind–body support: Relaxation, mindfulness, and sleep hygiene may help you cope with chronic symptoms and stress. ^[7]

What to expect and long‑term outlook

• Many neurologic irAEs respond well to timely treatment, with favorable outcomes. [PM9]
• Some neuropathy may persist, but early recognition and therapy reduce the chance of long‑term disability. [PM7] [PM11]
• If symptoms are mild and not function‑limiting, careful monitoring while continuing immunotherapy may be reasonable, guided by your oncology and neurology teams. [PM7]

How is neuropathy distinguished from other causes?

Your team may:

• Take a detailed history and exam to separate neuropathy from myositis or myasthenia, which sometimes overlap. Clinical diagnosis is prioritized over antibody tests or imaging. [PM7]
• Order tests such as nerve conduction studies, lab work, and MRI when needed to clarify the diagnosis and rule out other causes. A coordinated, multidisciplinary approach improves outcomes. [PM9]

Key takeaways

• Immunotherapy can cause neuropathy, although it’s uncommon; early reporting of symptoms leads to better outcomes. [PM9] [PM7]
• Treatment usually includes pausing the drug and starting steroids; severe or resistant cases may need IVIg or plasma exchange. [PM11] [PM10]
• Daily coping strategies exercise, fall prevention, protective footwear, and symptom‑relief medications can meaningfully improve comfort and safety. ^{[5] [7]}
