This medicine is in a class of drugs called salicylates. It is used to reduce fever and relieve pain and inflammation. It may be used to treat arthritis.

Salicylates can cause serious side effects such as Reye's syndrome in children and adolescents with viral infections such as the flu or chickenpox. Ask your health care provider before giving this medicine to children with flu symptoms or poxlike skin blisters.

Aspirin is also used to help prevent and treat heart attacks and strokes.

It may be used for other conditions as determined by your health care provider.

• an allergy to any medicine or to tartrazine dye

• diabetes
• gout
• liver or kidney problems

Females of childbearing age: Tell your health care provider if you are pregnant or breast-feeding. Do not take aspirin during the last 3 months of pregnancy unless it has been ordered by your health care provider. Do not breast-feed while taking this medicine without your health care provider's approval.

This medicine works best when taken with food. Take it with a full glass (8 ounces) of water to lessen throat and stomach irritation. If you are taking this medicine for arthritis, take it regularly.

This medicine may come in different forms. If you have extended-release or enteric-coated tablets, do not break, crush, or chew them. Swallow them whole. Ask your pharmacist if you have the extended-release tablets.

If you cannot take aspirin orally, this medicine also comes in suppository form for rectal use.

To use the suppository:

Wash your hands before using this medicine. Remove the foil wrapper and moisten the suppository with water or water-based lubricating jelly. If the suppository is too soft to insert easily, run cold water over it or put it in ice water until it is firm. If it is too dry or hard, moisten it with warm water. Lie on your left side and bend your right knee up toward your chest. Gently push the suppository into your rectum so it is deep enough not to come out. Wait for a strong urge to empty your bowels before going to the bathroom.

If you miss a dose, take it as soon as you remember unless it is almost time for the next scheduled dose. In that case, skip the missed dose and take the next one as directed. Do not take double doses. If you are not sure of what to do if you miss a dose, or if you miss more than one dose, contact your health care provider.

Do not take other pain relievers or drink alcohol while you are taking this medicine unless your health care provider approves. They may increase the risk of stomach upset.

If you need emergency care, surgery, or dental work, tell the health care provider or dentist you are taking this medicine.

Do not use aspirin if it smells like vinegar. It can cause serious side effects.

Be aware of the risk of overdose. If you become seriously ill (severe dizziness, confusion, headache, ringing in the ears), get medical help right away.

Along with its needed effects, your medicine may cause some unwanted side effects. Some side effects may be very serious. Some side effects may go away as your body adjusts to the medicine. Tell your health care provider if you have any side effects that continue or get worse.
