Advil is a brand name for ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, inflammation, and fever [1]. However, it is not recommended for acid reflux, as it can cause irritation and inflammation of the stomach lining, which can worsen the symptoms of acid reflux [2].

Natural remedies can be used to alleviate the symptoms of acid reflux. For instance, a person can try to avoid foods and drinks that trigger acid reflux, such as caffeine, alcohol, fatty and spicy foods, and citrus fruits [2]. They can also eat smaller, more frequent meals, and avoid lying down for at least two hours after eating [2].

Additionally, there are several natural remedies that can help with acid reflux. Ginger has anti-inflammatory properties that can reduce inflammation in the esophagus and stomach [3]. Chamomile tea can help reduce inflammation and soothe the stomach lining [3]. Apple cider vinegar can help neutralize stomach acid and improve digestion [3].

However, it is important to note that natural remedies may not work for everyone, and some people may require medication to manage their acid reflux symptoms. It is always recommended to consult a healthcare professional before trying any natural remedies or stopping any medication [2].
