Upsides
  • When taking low doses (81 mg) every day, Aspirin provides protection for your heart and prevents heart attacks and stroke.
  • Used in higher doses to relieve pain, swelling, and fever.
  • Available over-the-counter in drugstores by itself and in combination with other cold and flu medications.
  • Works well to relieve muscle ache and pain caused by inflammation.
  • Minimal risk for addiction unlike narcotics.
  • Available in gel or powder packets if you have difficulty taking the pill.
  • Most forms are available as generic.
Downsides
  • Not a preferred medication for treating pain, swelling, or fever due to its high risk of bleeding.
  • NSAIDs (like ibuprofen and naproxen) and acetaminophen (Tylenol) are better for treating pain and fever thank Aspirin.
  • Aspirin raises your risk of bleeding, especially when used with other blood thinner medications like warfarin (Coumadin).
  • Studies show that using higher doses of Aspirin (162 mg or more) every day raises your risk of stomach bleeding and doesn't provide any additional heart protection.
  • Not for chronic, daily use because of increased side-effects.
  • May need to be taken two or three-times daily for maximum pain relief.
  • Can cause serious stomach problems like inflammation, ulcers, and bleeding.
  • Can raise your risk of having blood clots, heart attack, or stroke.
