Alfuzosin, a medication commonly used to treat enlarged prostate symptoms, can have negative impacts when mixed with alcohol. Alcohol has muscle-relaxing properties that decrease blood pressure, while alfuzosin relieves tension in the prostate and bladder muscles, making urination easier. When combined with alcohol, the hypotensive effects of alfuzosin can intensify, causing dizziness, lightheadedness, or even fainting. It is important to consult a medical professional regarding the possible risks and interactions associated with alcohol consumption while taking alfuzosin.
