Salicylamide (o-hydroxybenzamide or amide of salicyl) is a non-prescription drug with analgesic and antipyretic properties. Its medicinal uses are similar to those of aspirin. Salicylamide is used in combination with both aspirin and caffeine in the over-the-counter pain remedy "PainAid". It was also an ingredient in the over-the-counter pain remedy BC Powder but was removed from the formulation in 2009. It was used in later formulations of Vincent's powders in Australia as a substitute for phenacetin.
