To the Editor.—
Prescriptions labeled "as directed" have aroused my concern as well as that of pharmacists Powell, Cali, and Linkewich ("Inadequately Written Prescriptions," 226:999, 1973).Frequently, I write a prescription for a medication and "Sig: With manufacturer's directions." Almost inevitably, if I have occasion to see the label, it reads, "Take as directed."All too many pharmacists disregard the instruction on our prescription blanks to "Label as Such." They will not take the trouble to transcribe the recommended dosage provided by the manufacturer.A dose of vermifuge is dependent on the child's weight. Is it asking too much, if the mother provides the weight of each child, for the pharmacist to provide the dose for each child?Verbal instructions are unreliable; my handwriting is not very legible to patients. Cannot the pharmacist type out the manufacturer's instructions— or better still—give the patient the package insert, underlining the dosage instructions?
