Upsides
  • A first-choice blood pressure treatment for many people.
  • Lowers the risk of heart attack and stroke.
  • Similar to ACE inhibitors (like Lisinopril), with fewer side effects like cough and swelling.
  • Protects kidney function, which is especially useful for people with diabetes or mild-to-moderate kidney disease.
  • Recommended for anyone with heart failure since it lowers the risk of death and further damage to your heart.
  • Can be added to other blood pressure-lowering medicines if you need additional blood pressure control.
  • Makes urination easier in men with an enlarged prostate.
  • Helps people with PTSD get better sleep with fewer, less-intense nightmares.
Downsides
  • Requires a yearly blood test to see how the medicine is affecting your body.
  • Not safe to use if you're pregnant.
  • Not the best medicine to lower blood pressure by itself.
  • Likely to cause orthostatic hypotension. This means dizziness when you change positions (like standing up) because your blood pressure doesn't adjust quickly enough.
  • Not preferred for people 65 years or older.
