There are three ways to add a medication to a patient's chart:

To create a medication, click New or the Medication Name field and enter the medication you want to prescribe. 

Once you've selected the medication you want from the drug database, you'll see that the Dose and Route field have been populated as well.

You can favourite frequently-prescribed medications in Arya by clicking the ☆ (star icon) when adding new medications on a patient's Prescriptions page.

Once you star a medication, it will appear in the Medication Name field every time you create a new medication in Arya. 

Arya tracks changes every time your medications are updated. To see changes over time, find the medication in the Patient Profile tab and click the i icon next to it.

In the medication dialog, click Changes Over Time. You'll see information about what was changed, who made the change, and the date and time of the change.

You can discontinue medications on the patient's Prescriptions page by selecting the medication and clicking Discontinue. You can also select the medication in the Patient Profile tab and discontinue it from there.

To see a patient's discontinued medications, click on Show Discontinued below their active medications.

In the Prescriptions section, you can add a reason for discontinuing by clicking Add a Reason. If you select "Allergy", the drug will be automatically added to the patient's list of Allergies.
