Upsides
  • A first-choice blood pressure treatment for many people.
  • Calcium channel blockers work especially well for African Americans to lower blood pressure.

  • Prevents heart-related chest pain (angina) if you take it regularly.

  • Lopressor (metoprolol tartrate) lowers the risk of death during and after a heart attack.

Downsides

  • Women are more likely to have side effects (especially swelling) from Verapamil than men.
  • You can't miss doses. Stopping Verapamil suddenly can cause your blood pressure to go up suddenly, which raises the risk of heart attack and stroke.

  • 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.
