JEVTANA shrinks tumors by attacking rapidly dividing cells, including cancer cells, so they can no longer grow and divide

What is the most important information I should know about JEVTANA?

JEVTANA may cause serious side effects, including:

Low white blood cells, which can cause you to get serious infections, and may lead to death. Men who are 65 years or older may be more likely to have these problems. Your healthcare provider (HCP):

• will do blood tests regularly to check your white blood cell counts during your treatment with JEVTANA.
• may lower your dose of JEVTANA, change how often you receive it, or stop JEVTANA until your HCP decides that you have enough white blood cells.
• may prescribe a medicine for you called G-CSF, to help prevent complications if your white blood cell count is too low.

Tell your HCP right away if you have any of these symptoms of infection during treatment with JEVTANA: fever (take your temperature often during treatment with JEVTANA), cough, burning during urination, or muscle aches.

Also, tell your HCP if you have any diarrhea during the time that your white blood cell count is low. Your HCP may prescribe treatment for you as needed.

Severe allergic reactions can happen within a few minutes after your infusion of JEVTANA starts, especially during the first and second infusions. Your HCP should prescribe medicines before each infusion to help prevent severe allergic reactions.

Tell your HCP right away if you have any of these symptoms of a severe allergic reaction during or soon after an infusion of JEVTANA: rash or itching, skin redness, feeling dizzy or faint, breathing problems, chest or throat tightness, or swelling of face.

JEVTANA can cause severe stomach and intestine problems, which may lead to death. You may need to go to the hospital for treatment.

Vomiting and diarrhea can happen when you receive JEVTANA. Severe vomiting and diarrhea with JEVTANA can lead to loss of too much body fluid (dehydration), or too much of your body salts (electrolytes). Death has happened from having severe diarrhea and losing too much body fluid or body salts with JEVTANA. Your HCP will prescribe medicines to prevent or treat vomiting and diarrhea, as needed with JEVTANA.

Tell your HCP if: you have vomiting or diarrhea, or if your symptoms get worse or do not get better. JEVTANA can cause a leak in the stomach or intestine, intestinal blockage, infection, and bleeding in the stomach or intestine. This can lead to death. Tell your HCP if you get any of these symptoms: severe stomach-area (abdomen) pain, constipation, fever, blood in your stool, or changes in the color of your stool.

Kidney failure may happen with JEVTANA, because of severe infection, loss of too much body fluid (dehydration), and other reasons, which may lead to death. Your HCP will check you for this problem and treat you if needed.

Tell your HCP if you develop these signs or symptoms: swelling of your face or body, or decrease in the amount of urine that your body makes each day or blood in your urine.

Lung or breathing problems may happen with JEVTANA and may lead to death. Men who have lung disease before receiving JEVTANA may have a higher risk for developing lung or breathing problems with JEVTANA treatment. Your HCP will check you for this problem and treat you if needed.

Tell your HCP right away if you develop any new or worsening symptoms, including: trouble breathing, shortness of breath, chest pain, cough or fever.
