Advil, also known as ibuprofen, is a nonsteroidal anti-inflammatory drug (NSAID) that is commonly used for short-term pain relief. It works by reducing inflammation and blocking the production of prostaglandins, which are chemicals that cause pain and inflammation in the body. However, whether Advil can be used for long-term pain relief is a more complicated question.

According to the Mayo Clinic [2], NSAIDs like Advil can be effective for long-term pain relief for some people, but they also carry risks. Taking NSAIDs for extended periods of time can increase the risk of gastrointestinal bleeding, kidney damage, and other side effects. Therefore, it is important to talk to a healthcare provider before using Advil or any other NSAID for long-term pain relief.

The Advil website [3] also notes that the drug is intended for short-term use and should not be used for more than 10 days unless directed by a healthcare provider. The website also advises against using Advil for chronic pain without consulting a doctor.

Additionally, the Drug Patent Watch website [1] provides information on the expiration dates of Advil patents, which suggests that the drug has been available for over 30 years and has been widely used for short-term pain relief. However, this information does not address the safety or effectiveness of using Advil for long-term pain relief.

In conclusion, while Advil may be effective for short-term pain relief, it is important to talk to a healthcare provider before using it for long-term pain relief. The drug carries risks and should not be used for more than 10 days without medical supervision. Patients with chronic pain should seek medical advice on appropriate long-term pain management strategies.
