Prazosin, sold under the brand name Minipress among others, is a medication used to treat high blood pressure, symptoms of an enlarged prostate (benign prostatic hyperplasia), and nightmares related to post-traumatic stress disorder (PTSD). It is an α₁ blocker that works by relaxing blood vessels, which lowers blood pressure and eases urinary symptoms. Although effective, it is a less preferred treatment for high blood pressure due to the risk of postural hypotension and other side effects. Prazosin is typically taken orally and requires consistent dosing for optimal results.

FAQ’s
While taking Prazosin, avoid alcohol and other substances that may lower blood pressure, as they can increase the risk of dizziness, fainting, and low blood pressure. Also, avoid standing up too quickly, as Prazosin can cause a sudden drop in blood pressure, especially after the first dose.
Prazosin generally begins to work within 1-2 hours of oral administration, with peak effects seen around 2-4 hours after dosing. Its blood pressure-lowering effect may last up to 24 hours, depending on the individual’s response.
Prazosin is sometimes not preferred as a first-line treatment for hypertension due to its tendency to cause postural hypotension (a sudden drop in blood pressure when standing up), especially at the start of treatment. Safer and more effective blood pressure medications are often chosen initially.
The major adverse effect of Prazosin is orthostatic hypotension, a condition where blood pressure drops significantly upon standing, leading to dizziness and potential fainting. This risk is most pronounced with the first dose or when doses are increased. Patients should take precautions, especially during the initial period of treatment.
