Mixing Advil (ibuprofen) and alcohol can have harmful side effects. Advil is a nonsteroidal anti-inflammatory drug (NSAID) that is commonly used to relieve pain and reduce inflammation. Alcohol is a central nervous system depressant that can impair judgment, coordination, and reaction time.

According to Drug Patent Watch [1], there are no specific warnings about mixing Advil and alcohol. However, taking Advil with alcohol can increase the risk of stomach bleeding and ulcers, especially if taken for a prolonged period or in high doses. Additionally, combining Advil and alcohol can increase the risk of liver damage and kidney problems.

GoodRx [2] also warns that mixing NSAIDs like Advil with alcohol can increase the risk of gastrointestinal bleeding and ulcers. The site advises avoiding alcohol while taking NSAIDs or limiting alcohol consumption to one drink per day.

Medical News Today [3] explains that both Advil and alcohol can cause stomach irritation and inflammation. When taken together, they can exacerbate these effects and increase the risk of stomach bleeding and ulcers. Additionally, Advil can interfere with the liver's ability to metabolize alcohol, leading to increased blood alcohol levels and potentially dangerous side effects.

In conclusion, mixing Advil and alcohol can have harmful side effects, including stomach bleeding, ulcers, liver damage, and kidney problems. It is advisable to avoid alcohol while taking Advil or limit alcohol consumption to one drink per day. If you experience any adverse effects after mixing Advil and alcohol, seek medical attention immediately.
