Treatlly lets you write a prescription on screen during the consultation and sign it electronically. The signed prescription becomes a PDF the patient can open from their appointment. This guide covers writing one, the checks that must pass before it will sign, and how to correct a prescription you have already signed.
Before your first prescription: upload your signature
You cannot sign a prescription until your signature image is on your profile. Go to your doctor profile, edit it, and upload a clear image of your signature.
Do this once, before your first clinic. If you skip it, everything else works and you will only discover the problem at the moment you try to sign — with a patient waiting.
Writing the prescription
Open the appointment and start the prescription. You add two kinds of item:
- Medicines — start typing a drug name and pick it from the catalogue. For each one you set dose, frequency, timing (before food, after food, or either) and duration.
- Investigations — lab tests you want the patient to have done. These are searched the same way.
A prescription needs at least one of the two. A prescription with only lab tests and no medicines is perfectly valid and will sign. Only one with neither is rejected.
Medicines you use often rise to the top of your suggestions over time — the system learns from what you actually sign, per doctor.
Dictating instead of typing
If voice dictation is switched on for your clinic, you can speak the prescription rather than type it. You dictate normally — drug, dose, frequency, duration — and it comes back as structured lines you can review.
Anything the system is not confident about is marked for review. Those items are highlighted, and they will block signing until you confirm or correct each one. That is intentional: a prescription should never be signed with a machine's guess in it that you have not looked at.
See AI Pack: voice dictation and suggestions for what the feature does and how the allowance works.
Signing
Signing is the point at which the prescription becomes a real document. Five checks run, in order, and any one of them stops it:
| Check | What it means |
|---|---|
| Already signed | This prescription has been signed already. Use a correction instead — see below. |
| Nothing to prescribe | No medicines and no investigations. Add at least one. |
| Items awaiting review | One or more dictated items are still flagged. Confirm or edit each before signing. |
| Signature missing | Your signature image is not on your profile. Upload it, then sign. |
| Restricted for video consultations | Only on video consultations: a prescribed drug falls in a class the Telemedicine Practice Guidelines do not permit to be prescribed remotely. |
That last one is worth understanding. It applies only to video consultations, never to a patient sitting in front of you. It covers classes such as sedatives and other controlled molecules. If you hit it, either prescribe an alternative or ask the patient to attend in person.
A signed prescription cannot be edited
Once signed, the prescription is locked. No field can be changed — deliberately, because a prescription is a medical record and a silently edited one is worthless as evidence of what you actually advised.
To correct a mistake, issue a replacement. The original is kept and marked as superseded, and the new one becomes current. Both remain on record, so the correction trail is intact and the patient can see which is current.
This means it is worth reading a prescription once before signing, particularly a dictated one.
What the patient gets
Signing produces a PDF carrying your name, qualification, registration number and signature, the clinic's details, and the items you prescribed. The patient opens it from their appointment — see Viewing your prescriptions.
If prescriptions are not available
Digital prescriptions are switched on per clinic, and separately for video consultations and for walk-in visits. If the prescription option is missing for one kind of visit but present for the other, that is the setting, not a fault — your clinic admin controls it under Clinic Settings → Digital prescriptions.
