The TELUS Collaborative Health Record (CHR) has a fully integrated Drug Interaction Checker which is provided and powered by the leading Canadian company, Vigilance Santé.

When you create a prescription, and select a medication to prescribe, the interaction checker automatically identifies possible drug-drug interactions, drug-allergy interactions and drug duplications between the patient's current medications, allergies and any new medications prescribed.

If any interactions are identified, they display in the Alerts area of the prescription entry window in order of severity.

📌 Note: Medications and allergies NOT included in the drug interaction analysis are flagged on the right hand side, in red “Not included in analysis”.

To view more information about an alert (for example, to view specific drug dosing, side effects, contraindications, etc.), click it. The Vigilance Santé (VS) Portal opens, with details on the alert and the medication displayed.

For more details on the VS Portal click here.

⚠️ Important:

  • When you search for medications to prescribe, select medications with a DIN (Drug Identification Number). Only medications with DIN numbers are included in drug interaction checks.

  • When you record allergies in the patients chart (via Summary view), search for and select allergies with associated DINs (otherwise they are not included in drug interaction checks).


Can the drug to drug interaction checker work with my Formulary medications?

Yes, it can work with formulary medications. As long as you provide a valid DIN# when creating a formulary medication, it should be able to be included in the analysis (assuming that it also exists within the Vigilance Santé database).

Can I customize Drug Interaction Alerts on a per user basis?

Yes, it is possible to customize how interaction alerts appear within InputHealth on a per user basis. It is also possible to set an account alert threshold, this can however only be set up by the account owner. See Configuring the drug interaction checker.
