With rare exceptions, the procedures performed at KBEC do not require the administration of prophylactic antibiotics. If, however, you are advised by your physician to take antibiotics prior to gastrointestinal endoscopy, you may take them orally, 1 hour prior to the procedure, with a small amount of clear fluid. If you are uncertain if you require anti-biotics prior to your GI Endoscopy procedure or if you need a prescription, please call your doctor prior to your appointment.
