Early aspirin administration is an important intervention with someone who may be experiencing acute coronary syndrome (ACS). Aspirin helps inhibit platelets involved in forming or enlarging a coronary blood clot.
Aspirin does not replace emergency care. Call 911 immediately and do not delay EMS activation while administering aspirin.
Recognizing Possible ACS
Symptoms may include:
- Chest pain, pressure, tightness or burning
- Pain extending to the arms, back, neck, jaw or stomach
- Shortness of breath
- Sweating, nausea or vomiting
- Dizziness, weakness or unusual fatigue
Symptoms may be less typical in women, older adults and people with diabetes.
Recommended Aspirin Administration
The 2025 ACC/AHA guideline for ACS, published by the American Heart Association, recommends in Table 7 an oral aspirin loading dose of 162–325 mg and states:
“Aspirin (nonenteric coated) should be chewed, when possible, to achieve faster onset of antiplatelet action.”
For an alert patient who can safely chew and swallow and has no known contraindication, one non-enteric-coated 325 mg aspirin tablet meets this recommendation. Chewing speeds the tablet’s dissolution and the onset of its antiplatelet effect. 2025 ACC/AHA Guideline for Acute Coronary Syndromes
The aspirin does not need to be labeled “chewable” or “baby aspirin.” Chewable products are formulated mainly to be easier and more pleasant to chew. A standard non-enteric-coated aspirin tablet can also be chewed effectively.
Four 81 mg tablets provide a comparable 324 mg dose. HealthFirst provides a single 325 mg tablet to simplify and potentially expedite administration during an emergency.
Aspirin in HealthFirst Emergency Medical Kits
The 325 mg aspirin tablet supplied in HealthFirst medical emergency kits:
- Is not enteric coated
- Can be easily chewed
- Provides a guideline-supported loading dose in one tablet.
Do not give aspirin to a patient with a known aspirin allergy, a patient with active, severe bleeding, or anyone who cannot safely chew and swallow. If the patient becomes unresponsive and is not breathing normally, do not give oral medication—begin CPR and use an AED.
The key response sequence is: recognize the symptoms, call 911, administer aspirin when appropriate, monitor the patient and prepare to provide CPR and use an AED.
