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).
  • Makes pain episodes less frequent and makes it easier to be active without having chest pain.
  • A first-choice treatment for people who've had a heart attack.
  • Lopressor (metoprolol tartrate) lowers the risk of death during and after a heart attack.
  • Lopressor (metoprolol tartrate) is cheaper than the extended release version.
Downsides
  • Requires a yearly blood test to see how the medicine is affecting your body.
  • Not safe to use if you're pregnant.
  • You need to take Lopressor (metoprolol tartrate) with food twice a day for it to work best.
  • Taking Lopressor (metoprolol tartrate) may make you feel more tired or out of breath during exercise or your normal daily routines. This gets better for most people, but for some it may not go away.
  • Not a first-choice treatment for high blood pressure, unless you have heart failure or heart disease. It can also be added to other medicines 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 Lopressor (metoprolol tartrate) suddenly can cause your blood pressure to go up suddenly, which raises the risk of heart attack and stroke.
