It is an outdated drug, and its approval has been discontinued by the FDA. Mersalyl acid is currently replaced by less toxic non-mercury containing diuretics. The sodium salt of a mercury-containing derivative of salicylamide, was formerly used (often in combination with theophylline) to treat edema, due to its powerful diuretic properties.  Interestingly, it has been found to have antiviral properties in mice."}]
