Watch lists

A watch list is a saved question. Each check compares the result with the previous check and, when the dated evidence changed, adds one alert listing the evidence added and the evidence removed, newest first by date. The first check stores the result as the baseline and raises no alert.

Start a watch list

The Watch lists page: Elmiron and eye damage, and IBD drugs, each with what it watches.

On the Watch lists page, New watch list asks for A drug or A condition, then the Drug, a Side effect (optional) and a Look back of 30 days, 3 months or 12 months. Start watching saves it. A card in an answer that can be watched carries a "Watch this" button.

Each list shows its name, what it watches and its state. Two from the live app:

  • Elmiron and eye damage: "Timeline of pentosan polysulfate and eye damage"
  • IBD drugs: "New evidence for drugs of inflammatory bowel disease, last 12 months"

What is being watched

A watch list open: Sources disagree for Elmiron and eye damage, what was searched, and the Alerts line.

Opening a list shows the current result and what it covers. For Elmiron and eye damage: "Sources disagree: some sources report an association and others found none or report evidence against it." Then the coverage: "Searched: 3 label sets (3 with full history from Aug 2004), 114 of 183 studies read, FAERS reports from Jan 2004 to Jun 2026, 4,212 of 4,357 foreign regulator actions and 19 of 62 FDA approval reviews", and "pentosan polysulfate · 11 search terms for eye damage".

Under Alerts, before the first change: "No alerts yet. The next check adds any new dated evidence here."

What an alert holds

One alert covers one changed result. It lists the evidence added since the previous check, such as a reporting signal, a study, a regulator acting abroad or a label change, each linked to its source, and any item that dropped out of the result. Alerts appear in the app, on the watch list, with a "New" badge and their count.
