Eprescribing has become a fast, affordable and effective way for patients to receive their medications. They can order them from the comfort of their own homes by simply going online. However, there are several eprescribing rules that the online pharmacist must follow to be able to have an eprescribing business online. The rules are set to keep health, safety and business interests emphasized in this new technology.

The eprescribing systsem must have a transaction certification from a known eprescribing connectivity entity.

A very important rule that also is used at all doctor's offices and pharmacies is that the eprescribing system must be set up to view the patient's medication history. It needs to be viewed in real time. The system also needs to access the age, weight, and other health related factors to be able to prescribe the correct drug and dose.

Up-to-date insurance and formulary information should also be accessible. This way the patient's eligibility will be known and will help them get generic alternatives and co-pay information. Any time that the patient can save money should be utilized by this system. It also means that the patient will be ensured that the prescription can be easily refilled by the eprescribing system. It also ensures that the system can receive electronic renewals from any pharmacy.

The eprescribing system should only be using an electronic method to transmit prescriptions. Faxing should be set up only as a backup. Information about the medication should be included in the prescription such as allergic reactions, side effects and drug interactions. This also means that the system has to have access to a drug database at the time the prescription is written to find the information necessary for the drug.

All of the rules needed for proper eprescribing are set to ensure the safety of the patient using this system. The system should be set up much like a pharmacy where the patient goes in person. When it comes to any medications, information is of the utmost importance. The more information that can be obtained about the patient and the drug will always ensure a safe transaction.
