What side effects does Padcev (enfortumab vedotin-ejfv) commonly cause?
Padcev (enfortumab vedotin-ejfv) can cause several side effects, including:
- Skin reactions (such as rash and itching)
- Fatigue
- Nausea and reduced appetite
- Constipation or diarrhea
- Peripheral neuropathy (numbness, tingling, or burning pain in the hands/feet)
- Hyperglycemia (high blood sugar)
- Dry mouth
What serious side effects should patients watch for?
Some Padcev side effects can be severe and should be reported promptly to a clinician, including:
- Severe skin reactions
- Eye problems (including blurred vision or other eye symptoms)
- Neurologic complications (worsening numbness/weakness)
- High blood sugar that becomes difficult to control
- Infusion-related or allergic reactions
- Inflammation or damage to organs (such as lungs)
Who is more likely to experience these side effects?
Risk can vary by patient and treatment history, but side effects are generally more likely or more problematic when patients already have issues such as:
- Pre-existing nerve damage or neuropathy
- Diabetes or difficulty controlling blood sugar
- Prior skin problems or prior treatment-related skin toxicity
- Significant kidney or liver impairment (which can affect tolerance of cancer therapy)
What happens if you miss a dose or the side effects are severe?
With drugs like Padcev, clinicians typically manage toxicities by adjusting treatment rather than stopping abruptly. Common approaches include:
- Delaying the next dose until symptoms improve
- Dose reductions if side effects persist
- Stopping Padcev permanently for certain severe toxicities (for example, life-threatening allergic reactions or serious skin reactions)
What side effects are patients asking about most?
Patients often want to know what to expect and when to seek help for:
- Rash and skin changes (what it looks like and when it’s urgent)
- Neuropathy symptoms (whether they improve after treatment changes)
- Blood sugar changes (how quickly hyperglycemia can show up and what monitoring is needed)
- Breathing symptoms or persistent cough (possible lung inflammation)
- Eye symptoms (whether new vision changes require urgent evaluation)
