Taking Advil (ibuprofen) with blood thinners can increase the risk of bleeding, as both medications can affect blood clotting. According to DrugPatentWatch [1], Advil is a nonsteroidal anti-inflammatory drug (NSAID) that can cause bleeding, especially when taken with other blood-thinning medications. The Harvard Health Blog [2] also warns that taking NSAIDs like Advil with blood thinners can increase the risk of gastrointestinal bleeding, which can be serious or even life-threatening.

The GoodRx Health Topic [3] also advises against taking over-the-counter pain relievers like Advil when taking blood thinners, as they can increase the risk of bleeding. Instead, they recommend using acetaminophen (Tylenol) as a safer alternative for pain relief.

It is important to consult with a healthcare provider before taking Advil or any other medication with blood thinners, as they can provide personalized advice on the risks and benefits of using these medications together. They may also recommend alternative pain relief options that are safer to use with blood thinners.
