First, I want to address the first comment that said Osmoprep is "wonderful" and has "great insurance coverage". If you are anyone over the age of 50 and getting a colonoscopy you should be aware of the dangers. Visicol aka Osmoprep aka fleets has been known to lead to acute renal failure, kidney transplants, permanent dialysis, and even death. At the age of 50 most people’s kidney function drops in half and they can not handle the phosphorous load that comes with the Visicol, Osmoprep, or fleets. As for insurance coverage of Visicol or Osmoprep (as well as the new moviprep) ...it sucks. There are 14 large insurance plans in my state that cover over 50,000 people, and VI/OP is all tier 3 or worse on every plan. As for the new Moviprep...I have heard from patients that the taste is awful and only comes in lemon. The reps are lying to us about it only being a 2 liter prep, and it contains more sodium (salt) than most of the PEG preps. It has lots of salt and sodium ascorbates that are both diuretics, making it dangerous for patients that can not drink alot of fluid. Also most African Americans should beware of using the Moviprep. Patients with G-S-PD deficiency should not take the Moviprep b/c it contains sodium ascorbate and ascorbic acid. Please make any patients that are African American aware of this.
