Ibuprofin, including Advil, can raise blood pressure to dangerous levels for people who already have high blood pressure, according to WebMD. Advil is part of the non-steroidal anti-inflammatory drugs, or NSAIDs, class. NSAIDs retain fluid and decrease kidney function, which causes blood pressure to escalate.
The decision by a person with high blood pressure to take Advil should be made in consultation with a doctor, according to WebMD. A physician understands how to balance the pain and inflammation-reducing benefits of Advil with the potential risks of high blood pressure. If a doctor deems the risks to high, he may recommend an alternative pain-reducer, such as acetaminophen.
