I have been in the practice of Gastroenterology for over 30 years in New York. Cetacaine has been a part of my practice the entire time. It certainly has withstood the test of time and has proven to be well tolerated. Comprised of a perfect combination of effective ingredients, it helps facilitate upper endoscopic procedures. The variable formulations and methods of delivery make Cetacaine quite user friendly and versatile. The rapid onset of action is important in the endoscopy suite and one can be confident that its effects will last for the duration of the procedure. It is a welcome addition in the endoscopy suite!
