Simply Put, What Is Enfortumab Vedotin?
Imagine the cancer cells in your body acting like harmful weeds that need special nourishment to grow and spread. Enfortumab vedotin is a targeted therapy designed to locate a specific protein found on the surface of those cancer cells.
Once the medicine finds the target, it delivers its payload directly to the cancer cell to stop it from growing. This targeted approach prevents cancer cells from multiplying and spreading throughout your body. Doctors primarily use this medicine to treat bladder cancer (bladder cancer) and certain types of kidney and urinary tract cancers.
Unlike traditional chemotherapy that affects many healthy tissues indiscriminately, targeted medicines home in on specific markers. However, healthy cells can still be affected, which is why your care team monitors you closely throughout your therapy.
Things to Tell Your Doctor Before Starting Treatment
Before you receive your first dose, your doctor needs to review your complete medical history. Other health conditions can influence how your body reacts to this treatment. Share your full medical background openly, and let your doctor know if you have any of the following conditions:
- Diabetes (Diabetes Mellitus): Tell your doctor if you have diabetes or if your blood sugar levels tend to run high.
- Liver Problems: Inform your care team if you have any history of liver disease or impaired liver function.
- Lung Conditions: Mention any chronic lung issues, breathing difficulties, or past lung inflammation.
- Eye Issues: Report dry eyes, blurred vision, or any other vision changes you currently experience.
- Nerve Disorders: Let your doctor know if you feel numbness, tingling, or pain in your hands or feet.
- Allergies: Inform your care team about allergies to this medicine, other drugs, foods, or dyes.
- Pregnancy: Tell your doctor right away if you are pregnant, think you might be pregnant, or plan to become pregnant.
- Breastfeeding: Let your doctor know if you are currently nursing or feeding an infant with breast milk.

Check Availability →How Is This Medicine Given?
Enfortumab vedotin is not a pill you swallow at home. Instead, it is given as an infusion directly into a vein (intravenously) by trained medical staff in a hospital, clinic, or infusion center.
- Pediatric Use: If this medicine is ever considered for a child or adolescent, specialized pediatric oncology protocols and rigorous monitoring are required.
- Missed Appointments: If you cannot make it to your scheduled infusion appointment, contact your clinic right away to reschedule. Skipping or delaying doses can reduce treatment effectiveness.
- Overdose Risk: Because medical professionals give this treatment in a clinical setting, accidental overdose is rare. If you ever suspect an issue, contact your local emergency services or poison control center right away (call 911 in the US/Canada, 999 in the UK, or visit your nearest Emergency Department).
Important Things to Watch During Treatment
Receiving this medicine places new demands on your body. Pay close attention to how you feel and report any unusual symptoms to your doctor right away.
Body Fatigue and General Discomfort
Cancer treatments often cause generalized tiredness and low energy because they impact rapidly dividing cells in the body. You may feel weaker than usual or experience a reduced appetite. While managing fatigue is important, do not stop your treatment early without speaking to your doctor first. Always discuss lingering tiredness with your oncology nurse.
Blood Sugar Levels (Blood Sugar)
This medicine can cause your blood sugar levels to rise (hyperglycemia). If you already have diabetes, your risk is even higher, and your blood sugar may require more frequent checks. Watch for signs of high blood sugar such as extreme thirst, frequent urination, unusual fatigue, or blurred vision, and report them promptly.
Eye Health
Some patients experience dry eyes, irritation, or blurred vision during treatment. If you wear contact lenses, you might notice increased discomfort. Using preservative-free lubricating eye drops can often help soothe dry eyes. However, if eye pain, redness, or vision changes persist, contact your eye doctor or oncologist right away.
Infection Risk
Powerful cancer therapies can lower your white blood cell count, temporarily reducing your immune defense and increasing your risk of infections.
- Watch for fever, chills, a severe sore throat, or a persistent cough. Contact your doctor right away if these symptoms appear rather than waiting.
- Try to avoid close contact with people who have active colds, flu, or other contagious illnesses.
- Never take over-the-counter pain relievers or fever reducers like aspirin, ibuprofen, or naproxen without consulting your doctor first. These medicines can mask a fever and delay the detection of a serious infection.
Severe Skin Reactions
Skin changes are crucial to monitor. Serious skin reactions can develop weeks or months after starting treatment. Watch for fever or flu-like symptoms accompanied by a red or purple skin rash. These rashes can sometimes progress into blisters or peeling skin. Swelling of lymph nodes in your neck, armpits, or groin alongside a skin rash also requires urgent medical evaluation.
Pregnancy, Breastfeeding, and Fertility
- During Pregnancy: This medicine can cause severe birth defects if taken while pregnant. A pregnancy test is required before starting treatment. You must use a highly effective method of birth control during treatment and for at least 2 months after your final dose.
- For Male Patients: If your partner can become pregnant, you must use effective barrier contraception (such as condoms) during treatment and for at least 4 months following your last dose.
- Breastfeeding: Avoid breastfeeding during treatment and for at least 3 weeks after your last dose.
- Fertility: This treatment can impact your ability to have children in the future. Discuss any family-planning concerns with your doctor before starting therapy.
