Drug interaction checks for Tanzanian dispensers

A drug interaction warning is most useful when it appears before medicine leaves the counter. Separate references can help learning, but busy dispensers need timely prompts during the actual workflow.

The alert model should be practical. Minor warnings can support counselling, moderate warnings can invite review, and major or contraindicated combinations should require pharmacist authorization.

Privacy matters. Safety checking can work with allergy flags, chronic condition flags, active medications, and an internal patient UUID without storing names, phone numbers, addresses, or national IDs in the patient table.

If every warning looks urgent, staff eventually ignore the system. Separating severity lets a minor counselling note feel different from a contraindicated combination.

Role-based access matters too. A clerk should not see patient clinical data, while a pharmacist should be able to review serious risks, override with a PIN, and leave an audit trail.

A warning after the sale is a report. A warning before completion is a safety intervention, which is why APOTEKH places safety in the dispensing flow.
