In DrChrono, you have the ability to prescribe medications electronically. To do so, you'll need to have eRx setup. If you haven't done that yet, please visit our guide located here.
Navigating to the eRx Page
To begin prescribing, open up a patient's chart (Patients > Patient List or Search). 
To access the prescription page, select Send eRx on the chart's left-hand navigation bar.
Creating a New Prescription
When you hit Send eRx, you'll be brought to the new prescription page. Here you'll be able to fill out a new prescription form for your patient.
You can prescribe multiple prescriptions at once for a single patient by selecting the (
) button in the upper right-hand corner.
To begin, start by searching for your drug in the Medication box.
After you've selected your medication, fill out the rest of the form. We have some helpful tools that can help you in this process. For SIG, we have a SIG builder tool to the left of the box and for dispensing, we have a weight dosage calculator.
For each medication, you have the option to add this medication to the patient's medication list to make future prescriptions easier. To do this, check the Add to Medication List box near the bottom of the form.
Once you have completed the medication form, select a pharmacy in the section below. Search for a pharmacy by pharmacy name or by zip code. Only pharmacies that are connected via Surescripts will be displayed. If you can't find the patient's pharmacy, you will need to look up the pharmacy on the web and fax the prescription manually.
To the right of the pharmacy name, you can add the pharmacy to your patient favorites or set it as patient default.
Click Preview Prescription at the bottom of the page when finished.
Previewing Your Prescription
Before you send your prescription, you need to preview the information. When you hit Preview Prescription, you'll be taken to the Prescription Summary. Here, check your drug's interactions and ensure the quantities are correct.
Finally, you're ready to send. To send your prescription electronically, hit the green Send Prescription button. If you prefer to fax or need to print the prescription, you may also select those options.
When you hit Send Prescription, the status of your prescription will change to OK with a green checkmark to indicate that the prescription has been sent to the pharmacy.
