What Ingredients Are in Aspirin?


A regular aspirin tablet contains 325 milligrams of aspirin as the active ingredient. Inactive ingredients include cornstarch, hypromellose, powdered cellulose and triacetin and may include carnauba wax, according to Drugs.com. Some manufacturers use the name acetylsalicylic acid, another name for aspirin, according to the U.S. Food and Drug Administration.

Aspirin is an over-the-counter medication many people use for pain. It provides temporary relief of headaches, menstrual pain and arthritis. It also helps reduce fevers associated with colds. However, in children and teens, use of aspirin for chickenpox or flu sometimes results in Reye’s syndrome, reports Drugs.com. In some users, aspirin causes severe allergic reactions resulting in hives, asthma, facial swelling and shock.

While the labels do not include directions for daily use of aspirin, many health care providers prescribe it to reduce the chances of heart disease, according to the FDA. However, it warns that daily use is not right for everyone. The medication increases the blood flow to the heart and brain, reducing the chances of both heart attack and stroke; however, it does cause side effects. Using aspirin therapy with other medications increases the chances of side effects. Aspirin therapy may be a bad choice for people who are pregnant, have uncontrolled high blood pressure, ulcers, asthma or liver problems.
