A prescriber will often be asked as to the probable price of the prescription. He should never be led into hazarding a guess. The knowledge that the same prescription cost a previous patient a certain amount is no ground for an answer. Each pharmacy is, to a large extent, a law unto itself as to price, and the same applies to even the different clerks in the same establishment. There necessarily can be no fixed price for prescriptions, as the variety of combinations runs into countless thousands. Each charge is an estimate and the same man may charge 35 cents for a mixture today and 40 cents tomorrow. The fluctuations of the market, the condition of the customer, the character of the account, and many other factors enter into the fixing of the price. The druggist always marks the price charged on each prescription, so that if refilled a discrepancy will not occur. Where this practice is neglected the result is often unfortunate. If for particular reasons the prescriber should find it necessary to name a price to the patient, the amount should be plainly entered on the prescription and he should remember that he owes the pharmacist an explanation, as the doctor has no more right to dictate the price of filling than the druggist the price of prescribing. How oft, oh how oft, has every druggist asked a customer a dollar for a prescription, only to have him or her say, "Why, Doctor Blank said that only would cost me fifty cents!"The only recourse is to acknowledge himself a thief or discredit Dr. Blank's fund of. information.
