Aspirin After Motor Vehicle Accident (MVA)
Aspirin should NOT be taken routinely following a motor vehicle accident unless you are experiencing chest pain or other symptoms suggestive of a heart attack. 1, 2
When to Consider Aspirin After MVA
Aspirin administration after an MVA should be based on specific symptoms, not the trauma itself:
ONLY take aspirin if:
- You are experiencing chest pain that suggests cardiac origin
- You suspect you may be having a heart attack
- You have no contraindications to aspirin (like allergies or recent bleeding)
Do NOT take aspirin if:
- The chest pain does not appear cardiac in origin
- You are uncertain about the cause of your symptoms
- You have active or recent bleeding
- You have a known aspirin allergy
- You are currently taking anticoagulants
Evidence-Based Guidelines
The American Heart Association provides clear guidance on aspirin use in emergency situations 1:
- If chest pain suggests a heart attack, 160-325 mg of non-enteric coated aspirin is recommended
- The aspirin should be chewed rather than swallowed whole for faster absorption
- Always call EMS immediately for anyone with chest pain or other signs of heart attack
- While waiting for EMS, aspirin may be taken if signs suggest a heart attack and there are no contraindications
Important Considerations
Trauma vs. Cardiac Events: Aspirin has no proven benefit for trauma management alone and may increase bleeding risk following an MVA 2
Bleeding Risk: Aspirin inhibits platelet function and may worsen bleeding in trauma patients
Timing Matters: If cardiac symptoms are present, early administration of aspirin is critical for reducing mortality from heart attacks 2
First Aid Priority: The first priority after an MVA should be to assess for injuries, call emergency services, and follow standard first aid protocols
When to Seek Emergency Care
Call emergency services immediately if after an MVA you experience:
- Chest pain
- Shortness of breath
- Dizziness or lightheadedness
- Severe pain anywhere in the body
- Visible injuries or bleeding
Bottom Line
Following an MVA, aspirin should only be considered if you are experiencing symptoms of a heart attack and have no contraindications to aspirin. In all other cases, aspirin should not be taken as it may increase bleeding risk without providing benefit.
