When a prescription is written it is the property of the pre-scriber until he delivers it to the patient, or to the druggist for the patient; it then ceases to be his and he has no legal right to recall it. If the patient has the prescription it is his to do with as he chooses, and when it is delivered to the druggist to be filled it becomes and remains the property of the druggist. The patient cannot demand its return nor can the physician, and should a prescriber for any reason wish to regain possession of one of his prescriptions that has been filled, he should remember that he is to ask the druggist for the favor of its return and not ,demand it. It is the same proposition as if the doctor sent an order to a merchant to deliver to his servant a pair of shoes. The merchant should retain the order as his evidence of the transaction. Of course, the major object in the pharmacist retaining prescriptions is really that he may have them in case it is necessary to have them refilled.
