Anyone with the ability, desire, and access CAN alter thelabel.If you are asking who is legally allowed to alter a label on adispensed medication that is about to be delivered to the patient:only a pharmacist or someone the pharmacist has allowed anddirected to change it. (Keep in mind that doctors are alsopharmacists.) This is an unusual occurrence, however. As puckeredas the medical community is about being sued it would boarderreckless and foolish. Generally, a new label will be printed andput on the bottle if it needs to be changed.Ultimately the label must match doctor's orders. In that sense,anyone who altered the label to reflect doctor's orders is fixingan inaccuracy and probably didn't do anything wrong by altering thelabel per se. If the pharmacist labels a medication bottle anddecides the medication is ready for delivery to the patient it willbe because the label matches doctor's orders and the pharmacistdecided it was safe to dispense said medication.If someone unlicensed tampered with the label after getting itfrom the pharmacy that is outside my scope of experience. I wouldthink at least possessing a prescription medication without beingthe person it was prescribed to (if they are not a licensedhealthcare professional) would be an issue.
