To manage the common medications in your agency, you need to access agency.epcriv.com
Once you have logged in, you will navigate to Agency Setup.

Next, you will click on the actions button, and then on edit.
Once you're inside the agency, you will have to navigate to the Configuration tab.
Once there, click on the Common medication tab.
You will find the following window.
In this window, you can select the medication you'd like, the dosage for that medication, the route to administer it, and the units of measurement.
If you'd like to add more medications, you can click on the button that says Add group and repeat the process.
To save all changes, simply click on the save button on the lower right side of your screen, and that way all new common medications will be saved.
