While creating an Encounter for a patient, you are able to add an Injection. You are able to do this by scrolling to the "Injections" section, and clicking on the "Add Injection" button on the right.
Once clicked, you are able to add information such as the type of injection (Allergy, Immunization, Injection, or Other), the name, dose, where the injection was given, and through which route. Also, known allergies of the patient will appear on the right hand side.
Other information can be added as well such as the lot number, sequence, strength, series, who it was injected by, the date of injection, serum, and other comments.
