Episode 21 — The doctor asked for one thing. I built something else
A doctor suggested something simple: that the owner of the medicine cabinet should be able to flag a medicine they’re allergic to. One field, you tick it, and that’s that. It sounds sensible — and that is exactly how it would have been built, were it not for one question asked a day later: what happens when a DIFFERENT box turns up in the cabinet? Because an allergy is to the active substance, not to one brand’s packaging. A flag placed on a single pack would stay silent when, a month later, you buy a medicine from another company with the same substance inside — precisely when the warning was needed most. That’s worse than not having the feature, because it gives you a false sense that somebody is keeping an eye out. This episode is about how a specialist’s request was translated into something other than what it sounded like — and about what the feature still does NOT do. What we cover: From the pack to the substance, and then to the person. A medicine cabinet at home doesn’t belong to one person. A warning has to know who it’s about, otherwise it’s noise. That dimension wasn’t in the original request at all — because a doctor is thinking about the patient across the desk, not about a drawer that five people use. Three deliberate limitations of the current version, said out loud: No cross-reactivity. If you enter an allergy to one substance, the app won’t automatically warn you about another, related one — unless you enter that one separately as well. Drug classes are clinical knowledge, and here a conversation with the pharmacist has no substitute. The matching is heuristic. With an unusual spelling the warning might not appear, and sometimes it might appear when it needn’t. Warn, never block. You can see the warning and hand the medicine out anyway. That’s deliberate: an app that blocks is making a medical decision on a person’s behalf. A warning says “check this”. A block says “you mustn’t”. Only one of those is an app’s to say. A bug that actually happened. With a feature that works per person, the most dangerous class of mistake is leakage between people — one person’s allergy shown against another person’s medicine. Sly, because the app still looks as though it’s working. An adverse reaction is not the same as a medication mix-up. There’s an official route for reporting adverse reactions, and it works. But a mix-up — taking the wrong medicine, a double dose because two people both gave it — is a different category. Here the medicine did exactly what it was supposed to; it just went to the wrong place. What couldn’t be found. A public, systematic picture of what goes on at the drawer at home. You could take a statistic from another country and multiply it by the population — it would look convincing on a slide and it would be made up. A different health system, a different way of counting, different habits. The ask in this episode isn’t “download the app”. It’s: let’s count it. Anyone. If only so it turns out the problem is smaller than it seems. What the app does NOT do: it doesn’t diagnose, it doesn’t set doses, it doesn’t judge whether a medicine is right for you, and it doesn’t tell you to take or skip anything. Its job is to make sure you know what you’ve got at home and what to ask about. The answer belongs to the pharmacist.
