1. Hypertension (High Blood Pressure):
   Prazosin relaxes blood vessels, lowering blood pressure and reducing the risk of heart attacks, strokes, and kidney problems.

2. Benign Prostatic Hyperplasia (BPH):
   It improves urine flow in men by relaxing the muscles in the prostate and bladder neck.

3. Congestive Heart Failure:
   In some cases, it is used adjunctively to reduce cardiac load and symptoms.

4. PTSD-related Nightmares:
   Off-label, prazosin is commonly prescribed to reduce nightmares and flashbacks associated with post-traumatic stress disorder.
