3.7/ 5 average rating with 535 reviewsforLosartan
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
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.
  • 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.
Downsides
  • Requires a yearly blood test to see how the medicine is affecting your body.
  • Not safe to use if you're pregnant.
  • 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.
