1. What Aspirin 75mg Gastro-Resistant Tablets is and what it is used for

Aspirin belongs to a group of medicines called antiplatelet agents that help prevent your blood cells sticking together and forming a blood clot.

Aspirin 75mg Tablets are principally used to prevent blood clots forming following a heart attack or stroke or to help prevent heart attacks and strokes in patients who have previously suffered from these conditions. They may have been prescribed for you if you have recently had by-pass surgery.

  • if you have, or ever had, an ulcer in your stomach or intestine
  • if you are under 16 years old, unless your doctor tells you to
