Nitrate: Health Effects in Drinking Water. Nitrate is one of the most common groundwater contaminants in rural areas. It is regulated in drinking water primarily because excess levels can cause methemoglobinemia, or blue baby disease.

About 80% of patients discontinue treatment after a year, and about 17% of the discontinuation is because of adverse side effects. Other medications that have been used for some types of urinary incontinence include alpha-adrenergic agents, duloxitene and topical estrogen.
