Prazosin is a medication primarily used to treat high blood pressure, symptoms of an enlarged prostate, and posttraumatic stress disorder (PTSD). It is a less preferred treatment of high blood pressure. Other uses may include heart failure and Raynaud syndrome. It is taken by mouth.

Common side effects include dizziness, sleepiness, nausea, and heart palpitations. Serious side effects may include low blood pressure with standing and depression. Prazosin is an &alpha;1-blocker. It works to decrease blood pressure by dilating blood vessels and helps with an enlarged prostate by relaxing the outflow of the bladder. How it works in PTSD is not entirely clear.

Prazosin was patented in 1965 and came into medical use in 1974. It is available as a generic medication. A month supply in the United Kingdom costs about £3.50 as of 2019. In the United States, the wholesale cost of this amount is about US$20. In 2017, it was the 227th most commonly prescribed medication in the United States, with more than two million prescriptions.
