Advil is a brand name for ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, fever, and inflammation [1]. The frequency of taking Advil for pain relief depends on the individual's age, weight, and the severity of the pain. The recommended dosage for adults is 200-400 mg every 4-6 hours, not to exceed 1200 mg in a 24-hour period [2]. However, it is always recommended to consult with a healthcare provider before taking any medication, especially if you have any underlying medical conditions or are taking other medications [3].

It is important to note that taking Advil or any NSAID for an extended period or in high doses can increase the risk of adverse effects, such as stomach bleeding, kidney damage, and heart attack [3]. Therefore, it is essential to follow the recommended dosage and duration of use and avoid taking it for more than ten days unless advised by a healthcare provider [2].

In summary, the frequency of taking Advil for pain relief depends on the individual's age, weight, and the severity of the pain. The recommended dosage for adults is 200-400 mg every 4-6 hours, not to exceed 1200 mg in a 24-hour period. However, it is always recommended to consult with a healthcare provider before taking any medication, especially if you have any underlying medical conditions or are taking other medications. It is also important to follow the recommended dosage and duration of use to avoid adverse effects.
