OsmoPrep Patients Now Requiring Dialysis Sue Salix Pharmaceuticals

Four North Carolina users of Salix Pharmaceutical's bowel cleansing prescription drug, OsmoPrep, have filed product liability lawsuits against the manufacturer alleging that they have suffered acute kidney damage and must now undergo dialysis after using the drug – which became subject to a U.S. Food & Drug Administration (FDA) black box warning in December of 2008.

OsmoPrep lawsuits

Four OsmoPrep users allege that they must now undergo kidney dialysis after suffering acute kidney damage – all of which could have been avoided had Salix Pharmaceuticals warned them of OsmoPrep's serious side effects.

Bowel cleansing products under fire

Salix Pharmaceutical's OsmoPrep and Visicol (sodium phosphate monobasic monohydrate and sodium phosphate dibasic anhydrous tablets), are both prescription bowel cleansing products used to cleanse the intestines prior to a colonoscopy, and are not the only bowel cleansing products under fire.

C.B. Fleet's Fleet Phospho-soda products, which were sold over the counter, were taken off the market in December of 2008 after the FDA reported that at least 20 patients developed acute phosphate neuropathy (kidney damage which can result in serious injury or death) and must also undergo dialysis after using the oral sodium phosphate (OSP) products. Consumers want to know why the companies sold these products if they were dangerous – and rightfully so.

What did manufacturers know?

Oral sodium phosphate injury lawyers say that manufacturers knew, or should have known, that OSP products could cause acute phosphate nephropathy (APN), or kidney failure and should have warned consumers about the potentially increased risks.

OSP attorneys also allege that C.B. Fleet recommended that patients take double dosages before colonoscopies without having studied the long term effects of that advice beforehand. So far, over 100 lawsuits have been filed against C.B. Fleet – many of which have been consolidated into an MDL (multi-district litigation) in the U.S. District Court for the Northern District of Ohio and others are now being filed against Salix.
