Advil is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, fever, and inflammation. According to the Advil website [2], it is recommended to take Advil with food or milk to help prevent stomach upset. However, it is important to follow the dosing instructions on the label or as directed by a healthcare professional. The maximum daily dose of Advil for adults is 1200 mg per day, divided into three or four doses [2]. It is not recommended to exceed this dose, as it may increase the risk of side effects such as stomach bleeding, kidney damage, and heart attack [3]. It is also important to avoid taking Advil if you have a history of stomach ulcers or bleeding, heart disease, or kidney disease, or if you are taking blood-thinning medications [3]. It is always recommended to consult with a healthcare professional before taking any medication, especially if you have any underlying health conditions or are taking other medications.
