Can You Overdose on Cough Drops: How Many are Too Many?
It is possible to overdose on cough drops, but it is not very likely to happen. When talking about an “overdose,” it refers to ingesting too much of the menthol they contain. The lethal dose of menthol is one gram per kilogram of body weight and one typical cough drop contains about 3 to 10 milligrams. Mathematically, that means you’d have to eat many cough drops within a limited amount of time to experience menthol poisoning.
