Keep the medicine away from children, or they may take it by mistake.

Hi,

Is "by mistake" in the above interchangeable with "wrongly?" Thanks.

Not really; 'wrongly', besides sounding rather old-fashioned, could mean that the children may take incorrect dosages-- which is not the point.

Thanks, Mister.

To make sure, does "by mistake" in question refer to "by accident?"
