According to the sources provided, it is generally safe to take other painkillers with Advil (ibuprofen). However, it is important to exercise caution and consult a healthcare professional or read the product labels for specific instructions and warnings.

The first source, Drug Patent Watch, provides information about the active ingredient in Advil, which is ibuprofen. It does not specifically address the combination of Advil with other painkillers. Therefore, we will rely on the other two sources for more comprehensive information.

The second source, the National Health Service (NHS) website, offers guidance on taking ibuprofen, including Advil, with other medicines and herbal supplements. It suggests that ibuprofen can be taken alongside other painkillers, such as paracetamol (acetaminophen) or aspirin, as long as the recommended dosages are followed. However, it is important to note that combining different painkillers may increase the risk of side effects, so it is advisable to consult a healthcare professional if you are unsure.

The third source, the Advil website, also addresses the issue of combining medications. It states that Advil can be taken with other pain relievers, but again, it emphasizes the importance of following the recommended dosages and consulting a healthcare professional if you have any concerns or questions.

In summary, based on the provided sources, it appears that taking other painkillers with Advil is generally safe, as long as the recommended dosages are followed. However, it is always advisable to consult a healthcare professional or read the product labels for specific instructions and warnings regarding the combination of medications.
