In DrChrono, you have the ability to prescribe medications electronically. To do so, you'll need to have eRx set up. 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 the SIG builder and dosage calculator that can help you in this process.
For SIG, we have a SIG builder tool to the left of the box for dispensing. Click on the gear(
) icon. Select the items from the columns and click update.
To use the dosage calculator, click the calculator (
) icon. A form will appear that allows you to input the dosage, weight, and liquid measurements of your patient and the medication to be prescribed.
To use the dosage calculator, follow the following steps.
- Enter the dose per unit of body weight for the medication. The calculator allows you to select between microgram/kilogram, milligram/kilogram, or gram/kilogram.
- Type in the body weight of the patient, your choice between kilograms or pounds
- The dose required will appear in the Dose section. For a non-liquid dose, select Use, and your dosage will be automatically populated to your e-prescription dispense and unit fields.
- If you are using a liquid dose, type in the medication's concentration (microgram, milligram, or gram per liter or milliliter). Your liquid dose will appear in the Liquid Dose section of the calculator. Select Use to populate your dispense and unit fields.
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.
