Advil is a brand name for ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) that is used to relieve pain, fever, and inflammation [1]. Advil is available in various forms, including tablets, capsules, and liquid gels [2]. According to a study published in the US National Library of Medicine, ibuprofen is commonly used in combination with other medications, such as acetaminophen, to provide more effective pain relief [3]. However, it is important to note that combining medications can increase the risk of side effects, so it is essential to consult a healthcare professional before taking any new medications or combinations of medications.
