Claim:
A method for look-alike sound-alike medication error messaging, comprising: calculating, by a host server, a set of most common daily dosage (MCDD) values or a set of common daily dosage (CDD) values for each of a plurality of drug products, based at least in part on dosage values from previously received prescription claim transactions received by the host server from a plurality of pharmacy point of service (POS) devices; storing, in a database accessible by the host server, the MCDD or CDD value sets for each of the plurality of drug products; receiving, at the host server, a prescription claim transaction from a pharmacy POS device; determining, from the prescription claim transaction received at the host server, a submitted drug product and a submitted daily dosage for the submitted drug product, wherein the submitted drug product is one of the plurality of drug products stored in the database; determining, by the host server, that the submitted drug product is associated with at least one look-alike sound-alike alternative drug product; determining, by the host server, that the submitted daily dosage is not within the MCDD or CDD value sets for the submitted drug product based on a comparison of the submitted daily dosage to the MCDD or CDD value sets for the submitted drug product; determining, by the host server, that the submitted daily dosage is within the MCDD or CDD value sets for the at least one look-alike sound-alike alternative drug product based on a comparison of the submitted daily dosage to the MCDD or CDD value sets for the at least one look-alike sound-alike alternative drug product; determining that the prescription claim transaction should be rejected based at least in part on the determination that the submitted daily dosage is within the MCDD or CDD value sets for the at least one look-alike sound-alike alternative drug product; generating a reject message at the host server, wherein the reject message indicates a potential prescription error has been detected; and transmitting the reject message from the host server to the pharmacy POS device.
