Aspirin Content in Excedrin

Two Excedrin (acetaminophen/aspirin/caffeine) tablets contain 500 mg of aspirin total 1.

Composition Details

Each Excedrin Migraine caplet contains 1:

  • 250 mg aspirin (NSAID)
  • 250 mg acetaminophen
  • 65 mg caffeine

Therefore, 2 caplets = 500 mg aspirin.

Clinical Context

This 500 mg aspirin dose in the combination formulation falls within the therapeutic range used in various clinical settings:

  • Migraine treatment: The combination of acetaminophen 500 mg, aspirin 500 mg, and caffeine 130 mg (similar to 2 Excedrin tablets) has demonstrated significant efficacy for acute migraine attacks, with superiority over placebo for pain-free response at 2 hours 2

  • Cardiovascular prevention: For comparison, low-dose aspirin for cardiovascular indications typically ranges from 75-162 mg daily 3, 4, which is substantially lower than the acute analgesic dose in Excedrin

  • Acute pain management: The 500 mg aspirin dose in combination products is within the standard range (650-1000 mg every 4-6 hours) used for acute pain relief 5

Important Safety Considerations

  • This is an acute treatment dose, not intended for daily chronic use
  • The combination with caffeine enhances analgesic efficacy and speeds onset of pain relief 6, 7
  • Contraindications include aspirin allergy, bleeding disorders, and G6PD deficiency 5
  • Limit use to avoid medication-overuse headache (maximum 10 days per month) 8
