Downsides and risks
CoregPrazosin
  • 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.

  • 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.
