After conducting research using the available information, I found that the onset time for Advil's effectiveness varies depending on the individual and the condition being treated. However, generally, Advil, a common brand name for Ibuprofen, begins to work within 20-30 minutes when taken orally [1]. It's important to note that this time frame can vary based on several factors, including the individual's metabolism, the severity of the pain or inflammation, and whether the Advil is being taken on an empty stomach or not.

Advil is a non-prescription, non-steroidal anti-inflammatory drug (NSAID) that is used to relieve pain, reduce inflammation, and lower fever [2]. It works by inhibiting the production of prostaglandins, chemicals in the body that cause pain and inflammation [3].

In conclusion, while the average onset time for Advil's effectiveness is around 20-30 minutes, this can vary from person to person. It's always recommended to follow the instructions on the packaging or consult with a healthcare provider for proper usage.
