Aspirin

What is Aspirin?

Aspirin (acetylsalicylic acid) is one of the oldest and most widely used medications in the world. It belongs to the NSAID class and has three main effects: it relieves mild to moderate pain, reduces fever, and reduces inflammation. At low doses (75mg), it also has blood-thinning (antiplatelet) properties, which is why it is widely used to prevent heart attacks and strokes in people at risk.

Uses of Aspirin

  • Pain relief — headaches, toothache, period pain, muscle pain (300–900mg doses)
  • Fever reduction
  • Prevention of heart attacks and strokes — low-dose aspirin (75mg) prevents platelets from clumping together and forming clots
  • Treatment of acute heart attack — 300mg chewed immediately as first aid
  • Antiphospholipid syndrome
  • Kawasaki disease
  • Pre-eclampsia prevention in pregnancy (under medical supervision)

Who Should Not Take Aspirin?

  • Children under 16 (risk of Reye's syndrome)
  • People with stomach ulcers or bleeding disorders
  • Those with aspirin allergy or asthma triggered by NSAIDs
  • Pregnant women (except low-dose under medical supervision)

Side Effects

  • Stomach irritation and indigestion
  • Increased bleeding risk
  • Stomach ulcers with long-term use
  • Tinnitus at high doses
