All Xchart.com accounts come with a list of commonly used drugs. But you can add any drug you want to your list that we can match against the National Institute of Health database.
To find this go to the dashboard within your account. Select "custom drugs" on the list to the left. Start typing the drug name and it will autocomplete.
Once the drug is added it will appear in your drugs list and can be added as a preset if you choose.
See steps below.
