Advil is a brand name for the drug Ibuprofen, which belongs to a class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs). Advil is commonly used to relieve pain, reduce fever, and reduce inflammation in the body [1]. According to MercyCare [2], Advil is effective in relieving mild to moderate pain, such as headaches, menstrual cramps, toothaches, and muscle aches. Advil is also effective in reducing inflammation caused by conditions such as arthritis, sprains, and strains [2].

Advil works by inhibiting the production of prostaglandins, which are chemicals that cause inflammation, pain, and fever in the body [3]. By blocking the production of prostaglandins, Advil can reduce pain, fever, and inflammation in the body [3].

It is important to note that Advil should not be used by individuals who are allergic to aspirin or other NSAIDs, or by individuals who have a history of stomach ulcers, bleeding disorders, or kidney disease [2]. It is also important to follow the recommended dosage instructions and to avoid taking Advil for more than 10 days without consulting a healthcare provider [2].

In summary, Advil is a brand name for Ibuprofen, which is a type of NSAID that is effective in relieving mild to moderate pain, reducing fever, and reducing inflammation in the body. Advil works by inhibiting the production of prostaglandins, which are chemicals that cause inflammation, pain, and fever in the body. However, it is important to use Advil responsibly and to follow the recommended dosage instructions to avoid potential side effects [1][2][3].
