Upsides
  • 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.
  • 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 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.
  • 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.
