Advil is a brand name for the drug ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce fever, and decrease inflammation [1]. According to Advil's official website, Advil can be used to treat minor aches and pains, headaches, toothaches, menstrual cramps, arthritis, and back pain [2].

However, it is important to note that ibuprofen should not be taken by everyone. People with a history of stomach ulcers or bleeding, heart disease, high blood pressure, kidney disease, or liver disease should consult their doctor before taking Advil or any other NSAID [2].

When it comes to deciding between Advil and other pain relievers, MercyCare suggests that acetaminophen (the active ingredient in Tylenol) is generally safer for people with certain medical conditions, such as kidney disease or stomach ulcers, while ibuprofen may be a better choice for people with arthritis or joint pain [3].

In terms of timing, Advil can be taken every 4-6 hours as needed for pain relief, but should not be taken for more than 10 days without consulting a doctor [2]. It is also important to follow the recommended dosage instructions on the packaging and not exceed the maximum daily dose of 1200mg [2].

In summary, Advil (ibuprofen) can be taken for a variety of minor aches and pains, but should not be taken by everyone and may not be the best choice for people with certain medical conditions. It can be taken every 4-6 hours as needed for pain relief, but should not be taken for more than 10 days without consulting a doctor. It is important to follow the recommended dosage instructions and not exceed the maximum daily dose of 1200mg.
