1 What Aspirin tablets are and what they are used for

Aspirin tablets belong to a group of medicines which have analgesic (pain relieving), anti-inflammatory (inflammation reducing) and antipyretic (temperature reducing) properties.

These tablets may be used for the relief of:

  • headache, toothache, migraine, neuralgia (nerve pain), sore throat or period pains.
  • symptoms of influenza, feverishness, rheumatic pains, sciatica (nerve pain of the leg/back), lumbago (lower back pain), fibrositis (muscular rheumatism), muscular aches and pains.

The tablets may also be used to prevent blood clots especially after a heart attack or in patients with unstable angina or reduced blood flow in the brain.
