Advil is a brand name for ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammation. According to the Cleveland Clinic [3], NSAIDs can interact with other medications and can have adverse effects on the stomach, kidneys, and cardiovascular system. Therefore, it is essential to check with a healthcare provider before taking Advil with other medications.

The CDC [2] recommends that individuals with severe COVID-19 symptoms should seek medical attention and follow their healthcare provider's advice regarding treatments. It is important to inform the healthcare provider about all medications, including over-the-counter drugs like Advil, to avoid any potential interactions or adverse effects.

Drug Patent Watch [1] provides information about the patent status of Advil. However, it does not provide information on whether Advil can be taken with other medications.

In conclusion, it is crucial to consult a healthcare provider before taking Advil with other medications. This is because NSAIDs can interact with other drugs and have adverse effects on the body. It is also essential to follow the advice of healthcare providers regarding treatments for severe COVID-19 symptoms.
