Possible side effects with JELMYTO
Contact your doctor’s office right away if you develop any of the side effects listed below or if they worsen.
JELMYTO may cause serious side effects including:
- Swelling and narrowing of the tube that carries urine from the kidney to the bladder (ureteric obstruction): Your doctor may recommend the placement of a small plastic tube (stent) in the ureter to help the kidney drain. This will help you urinate and protect your kidney. Tell your doctor right away if you develop side pain or fever during treatment.
- Bone marrow problems: JELMYTO can affect your bone marrow and may cause a decrease in your blood cells. Your doctor will do blood tests before each treatment.
