Advil is a brand name for the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen [1]. It is commonly used to treat pain, inflammation, and fever. According to the Cleveland Clinic, taking ibuprofen regularly or before bed can have negative effects on the body [2]. The recommended dosage for Advil is no more than 1200 mg per day for adults, which can be taken as 400 mg every four to six hours [3]. However, it is important to note that taking Advil before bed can cause drowsiness, as it is often combined with diphenhydramine, a sedating antihistamine, in Advil PM [3]. It is recommended to consult with a healthcare provider before taking any medication, especially if you have underlying medical conditions or are taking other medications.
