Advil is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammation. It is important to take Advil as directed by a healthcare provider or the instructions on the label. According to the National Kidney Foundation [2], over-the-counter pain relievers, including Advil, can cause kidney damage if taken too frequently or for a prolonged period. Taking Advil more than the recommended dose or for more than ten days can increase the risk of kidney damage.

The NHS Inform [3] recommends taking ibuprofen with or after food to reduce the risk of stomach irritation. The maximum recommended dose for adults is 1200mg per day, which is equivalent to six 200mg tablets. It is important to avoid taking more than the recommended dose or taking Advil for a prolonged period.

Drug Patent Watch [1] provides information about the patent status of Advil. However, it does not provide information about the safe dosage or frequency of use.

In summary, it is important to follow the recommended dosage and duration of use for Advil to avoid kidney damage and other adverse effects. Patients should always consult their healthcare provider before taking Advil or any other medication.
