Coreg (Carvedilol)

Prescription only

Minipress (Prazosin)

Prescription only
Lowers blood pressure and controls heart rate.

Coreg (Carvedilol) is good for controlling chest pain and treating heart failure and heart attack. You have to take it with food, and you can't miss doses.

3.5/ 5 average rating with 406 reviewsforCoreg
Lowers blood pressure and makes it easier to urinate.

Prazosin is used mostly to make urination easier for men with an enlarged prostate, but it can cause dizziness.

Upsides
  • A first-choice treatment to prevent chest pain (angina).
  • A first-choice treatment for heart failure and heart attack.
  • For people with severe heart failure, Carvedilol lowers the risk of worsening heart failure, hospitalization, and sudden death.
  • 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
  • You have to take Carvedilol with food.
  • Taking a beta blocker might make you feel more tired or out of breath during exercise or normal daily routines. This gets better for most people, but for some might not go away.
  • Not a first-choice treatment for high blood pressure according to the latest guidelines, except if you have heart failure or heart disease. As a second choice, your doctor might add it to medicines you're already taking if your blood pressure is still too high.
  • Can hide symptoms of low blood sugar if you're diabetic.
  • You can't miss doses. Stopping Carvedilol suddenly can cause your blood pressure to go up suddenly, which raises the risk of heart attack and stroke.
  • 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.
