Advil is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) that is used to relieve pain, fever, and inflammation [1]. Advil is commonly used to treat headaches, toothaches, menstrual cramps, arthritis, and other types of pain [2]. It works by blocking the production of prostaglandins, which are chemicals in the body that cause inflammation, pain, and fever [3].

Advil is usually taken orally in tablet, capsule, or liquid form, and it is available over-the-counter without a prescription [2]. The recommended dosage for adults is 200-400mg every 4-6 hours, not to exceed 1200mg in a 24-hour period [2]. The dosage for children is based on their weight and age, and it should be determined by a healthcare provider [2].

It is important to note that Advil is not appropriate for everyone. People who have a history of stomach ulcers, bleeding disorders, kidney disease, or asthma should consult with their healthcare provider before taking Advil [3]. Additionally, Advil should not be taken with other NSAIDs, such as aspirin or naproxen, as this can increase the risk of side effects [3].

In summary, Advil is a brand name for ibuprofen, which is a medication used to relieve pain, fever, and inflammation. It works by blocking the production of prostaglandins in the body. Advil is available over-the-counter and should be taken according to the recommended dosage. However, it is important to consult with a healthcare provider before taking Advil, especially if you have a history of certain medical conditions or are taking other medications.
