This article covers how to use ePrescribe to prescribe controlled substances.

Only Doctor and Mid-Level users will be able to receive privileges to transmit controlled substances electronically. Nurse and Clerical user types will not be able to transmit controlled substances, so be aware of the privilege level of each MacPractice user.

How to Prescribe a Controlled Substance

First, in the ePrescribe interface, you’ll locate the name of the controlled substance via the Drug Search field as described in our Getting Started guide here: Getting Started with ePrescribe v2 | Composing Prescriptions

Once you’ve located the formulation you wish to use, click the medication in question.

Open

Next, you’ll fill out the Dispense and Dosage information as normal, also covered in our Getting Started guide: Getting Started with ePrescribe v2 | Step 2: Set the Dosage

Click Prescribe when you’re satisfied with the dosage information, or alternately you can click the drop down arrow next to the Prescribe button to Queue Rx if you have multiple prescriptions you wish to transmit at once.

Open

On the Transmit Rx view where you typically review the details of your medication and the Pharmacy information, you’ll see a PIN field. This is your EPCS Pin that was set up during the EPCS registration process.

Enter your PIN in the indicated field and click the “Enter PIN” button:

Next, you’ll need to use an OTP device (One Time Password) to provide a passcode for Two-factor authentication. This can either come from a physical Hardware Token or the Authy App on a modern Android or Apple phone, and can be entered manually or by Push Notification to a text-capable device.

Once you’ve received your passcode, enter it into the Passcode field and click the “Sign & Transmit Rx” button.

Once you’ve done this, you will receive a receipt that indicates the prescription was transmitted to the pharmacy.
