People with lung, kidney disease, gout, hyperuricemia (high amounts of uric acid in the blood), hemophilia (a blood clotting disorder), diabetes or high blood pressure should not take aspirin except on the advice of a qualified medical professional. Nor should people who are allergic to it, to ibuprofen or to naproxen. People with asthma where attacks are brought about by aspirin should avoid using any anti-inflammatory drugs based on it.
