A significant proportion of infant rats of both sexes are expected to die at a dose of 800 mg/kg. Excessive acidity also delays stomach emptying thus delaying the absorption of levodopa. Although the color appears to be clinically insignificant, garments may become discolored.The patient should be advised that a change in diet to foods that are high in protein may delay the absorption of levodopa and may reduce the amount taken up in the circulation.
