What side effects does Adcetris (brentuximab vedotin) commonly cause?
Adcetris side effects depend on the cancer being treated and the treatment schedule, but common reactions include effects related to infusion and the drug’s targeted cell-killing payload. Patients can experience:
- Peripheral neuropathy (numbness, tingling, burning pain in hands/feet)
- Nausea
- Fatigue
- Diarrhea or constipation
- Fever
- Cough or shortness of breath
- Infusion-related reactions
What serious side effects should patients watch for?
Serious or urgent side effects can include:
- Worsening or persistent neuropathy that may affect walking or performing daily tasks
- Low blood counts (such as neutropenia), which can increase infection risk
- Infections, including serious infections
- Lung problems (including inflammation)
- Tumor lysis syndrome (can occur after treatment starts in some high-burden cancers)
- Liver or other organ problems
- Severe allergic or infusion reactions
- Eye problems (rare)
Can Adcetris cause nerve damage, and is it reversible?
Peripheral neuropathy is one of the best-known Adcetris risks. Symptoms can start during therapy and may improve after dose changes or stopping treatment, but some patients have long-lasting symptoms. Clinicians often monitor symptoms closely and adjust dosing if neuropathy worsens.
What side effects are different when Adcetris is used with other cancer treatments?
When Adcetris is combined with chemotherapy or given in different disease settings, side effects may overlap with those caused by the partner treatment. This can mean higher rates of low blood counts, infection, nausea, and fatigue compared with single-agent use, and it can also make it harder to tell which drug caused a specific symptom.
What should you do if symptoms start during treatment?
Patients taking Adcetris should contact their oncology team promptly for:
- New or worsening numbness/tingling or trouble with balance
- Fever or signs of infection
- Shortness of breath, new or worsening cough
- Severe rash, swelling, or breathing difficulty (possible infusion reaction)
- Severe diarrhea, abdominal pain, or signs of dehydration
- Symptoms that could suggest serious reactions such as eye or lung problems

If you tell me your indication (for example, Hodgkin lymphoma, systemic anaplastic large-cell lymphoma, or another setting) and whether it’s Adcetris alone or with another drug, I can narrow down the most relevant side effects for that specific use.
