What side effects are reported for Padcev (enfortumab vedotin-ejfv)?
Padcev (enfortumab vedotin-ejfv) can cause side effects that fall into a few common categories seen with antibody-drug conjugates and chemotherapy-like activity: skin reactions, nerve (neuropathy) symptoms, blood sugar changes, fatigue, and eye or mouth effects. The prescribing information also notes risks that can be serious, including severe allergic reactions and complications that may require treatment interruption or discontinuation.
What are the most common Padcev side effects patients notice?
Commonly reported effects include tiredness/fatigue, decreased appetite, nausea, constipation or diarrhea, rash, and itching. Some patients also experience peripheral neuropathy symptoms such as numbness, tingling, or burning in the hands or feet. Hyperglycemia (high blood sugar) has been reported with Padcev, so patients with diabetes—or those at risk—often need closer monitoring during treatment.
What are the serious or “call your doctor right away” Padcev side effects?
Serious adverse reactions listed in Padcev’s safety information can include:
- Severe allergic reactions or infusion-related reactions
- Severe skin reactions
- Worsening neuropathy or neurologic symptoms
- High blood sugar that becomes dangerous, particularly in people with diabetes
Because timing can vary by person, the key practical point is that symptoms that are severe, rapidly worsening, or involve breathing/swelling, widespread rash/blistering, or new weakness or severe numbness should be treated as urgent.
Can Padcev cause neuropathy—how does it show up?
Yes. Peripheral neuropathy is one of the more clinically important side effects with Padcev. Patients commonly describe numbness, tingling, pain, burning, or reduced sensation in the feet and hands. Doctors often manage this by adjusting the dose schedule and using symptom management strategies; more severe neuropathy can lead to treatment delays or discontinuation.
Does Padcev affect blood sugar?
Padcev can raise blood sugar (hyperglycemia). Patients may notice increased thirst, frequent urination, blurred vision, or fatigue if glucose becomes high. Clinicians typically monitor glucose during therapy and adjust diabetes medications when needed.
Are there eye-related side effects with Padcev?
Yes. Eye irritation and other ocular complaints can occur with Padcev. Patients should report eye pain, significant redness, light sensitivity, or vision changes promptly, since some eye symptoms can require urgent evaluation.
How do side effects compare across bladder cancer treatments?
Padcev is used for certain locally advanced or metastatic urothelial cancers, often after prior therapies. Its side-effect profile is different from single-agent chemotherapy and differs from checkpoint inhibitors; neuropathy and skin reactions are especially notable for antibody-drug conjugates. The best comparison depends on which prior treatments a patient has had and what safety issues they experienced.
When side effects happen, what do clinicians usually do?
Management typically involves one or more of the following depending on severity: symptomatic treatment (for nausea, rash, or pain), more frequent monitoring (for glucose and blood counts), dose delays, or dose reductions. For severe allergic reactions or serious dermatologic events, treatment may be stopped.

I can pull the exact adverse-effect rates and the full “most common” and “serious” lists from the Padcev prescribing information, but I need one detail to do it correctly: are you asking about side effects for Padcev used in (1) locally advanced or metastatic urothelial cancer, and if so which line/combination (for example with pembrolizumab), or (2) a different setting?
If you tell me the regimen (Padcev alone vs Padcev + Keytruda/pembrolizumab, etc.) and whether you want common side effects or a full safety list, I’ll tailor the answer.
