"More than one dose", nah again
Even one dose of prescription medication, administered for anything other than for diagnostic purposes, is recordable.
Re: the description Steve gave following "sutures" : butterfly bandages are included on the first aid list, so are not recordable. Liquid bandage, likewise not recordable, but Dermabond surgical glue is recordable. Distinction is drawn between types of wound-closing devices that are topical only, while others are invasive.
Also, if the employee breaks his tooth during lunch or chokes on his ham sandwich and it was an employer provided meal then it is recordable. It is the "employer provided" that makes or breaks it, not a test of the job function. Work-related, as it is included in the current OSHA standard, is a presumption of the work environment unless one of the specific exemptions apply.
