Aspirin has two roles: at higher doses it relieves pain and fever, and at low doses it thins the blood to help prevent heart attacks and strokes. It is not for children.

Doses are a general reference, not a prescription. Doses shown are typical adult/paediatric references and vary with age, weight, kidney/liver function and the exact product. Paediatric doses are usually weight-based and must be set by a doctor. MedDroid cannot prescribe — always confirm aspirin and your dose with a doctor or pharmacist and the leaflet inside the pack.
Frequently asked questions
Should I take low-dose aspirin daily?
Only if your doctor advises it — usually for people with heart disease or high risk. Without need it can cause bleeding, so it is not for everyone.
Do I stop aspirin before surgery?
Sometimes, because it thins the blood — but follow your doctor’s specific instructions; do not stop a heart medicine on your own.
