Custom Drugs 

If you can’t find the drug you are looking for, you can create a custom drug prescription. This can be done from the screens for both Steps 1 and 2, as well as the link “I can’t find what I’m looking for” on the step 2 screen.

Warning: Only use this feature if absolutely necessary, as you will lost the following functionality:

  • known dosage forms/ routes
  • drug allergy information
  • drug-drug interaction information
  • drug information

Fill out the information and dosage as you would for a normal prescription, taking care to enter the name of the custom drug in the top text field.
