Our pharmacists’ bottom line
Verapamil works well to lower blood pressure and prevent chest pain, but you have to be okay with avoiding alcohol. You can't miss doses, and you might get persistent swelling.
- A first-choice blood pressure treatment for many people.
- Calcium channel blockers work especially well for African Americans to lower blood pressure.
- You can take it alone or with other medicines to help lower blood pressure.
- Lowers the risk of heart attack and stroke.
- Prevents heart-related chest pain (angina) if you take it regularly.
