Trauma & emergencies: fast disclosure saves time

Emergency response for patients on blood thinners

Updated 2026-02-04

In trauma, time and information matter. The most helpful thing you can do is disclose your medication early and clearly.

The 30‑second script (say this first)

“I take a blood thinner. The name is _____. My last dose was about _____. I hit my head / was in a crash / may be bleeding internally.”

If you can’t speak, show a note on your phone or a wallet card.

Common trauma situations where risk is underestimated

What to do immediately

Reversal in concept (not instructions)

Reversal options depend on the drug and situation. Some agents are drug-specific; others are supportive. The decision is made by clinicians based on bleeding severity, location (e.g., brain), and clotting risk.

See the Evidence page for high-level references.

Emergency rule of thumb: if there is potential for internal bleeding (especially head injury), get urgent assessment and disclose your blood thinner immediately.
