Without specific information about your personal experience with Advil, it's impossible for me to provide a direct answer to your question. However, I can provide some context about Advil's pain relief duration based on the available information.

Advil, a brand of ibuprofen, is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to treat pain, reduce inflammation, and lower fever [1]. According to the product label, the pain relief duration of Advil can last up to 8 hours [2]. This is consistent with a study that found ibuprofen provided significantly longer pain relief than acetaminophen, another common over-the-counter pain reliever [3].

It's important to note that the duration of pain relief can vary depending on the individual, the type and severity of pain, and the dosage taken [4]. Additionally, like all medications, Advil can have side effects, and it's important to follow the instructions on the label and consult with a healthcare provider if you have any concerns or questions [2].

In conclusion, based on the available information, Advil is designed to provide pain relief that lasts up to 8 hours. However, the actual duration can vary depending on various factors.
