Did You Know?

Acetaminophen is the most widely used pain reliever in the United States.

How does it work?

Acetaminophen works by elevating the body’s overall pain threshold, and it lowers fever by helping the body eliminate excess heat.

Where will I find acetaminophen?

You can find acetaminophen in prescription medicines and OTC medicines for the temporary relief of minor aches and pains due to headache, muscle aches, backache, the minor pain of arthritis, the common cold, toothache, and menstrual cramps, and to reduce fever. Acetaminophen is also used in combination with other active ingredients. to make common multi-symptom OTC medicines, such as cough suppressants, cold and flu products, and allergy medications.

Can I take acetaminophen?

When taken as directed, acetaminophen is safe and does not cause the stomach irritation often associated with non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin, naproxen sodium, and ibuprofen. That’s why doctors often recommend acetaminophen for people over 50, children, and those with such conditions as asthma, kidney disease, osteoarthritis, hypertension, or pregnancy. However, if you have any of these conditions, ask a health professional before using.

How much can I take?

Look on the container to find the strength of the pills you are planning to take and follow the directions for the number of pills and the number of times during the day you can take them. Never take more than 4,000 milligrams of acetaminophen in a day, unless your doctor tells you otherwise.
