Calcium channel blockers are prescription medications that relax blood vessels and increase the supply of blood and oxygen to the heart while also reducing the heart's workload. Examples of calcium channel blockers include:
Potassium plays a role in every heartbeat. A hundred thousand times a day, it helps trigger your heart to squeeze blood through your body.
It also helps your muscles to move, your nerves to work, and your kidneys to filter blood.
Calcium channel blockers should be taken with food or milk. Follow the label directions on how often to take it. The number of doses you take each day, the time allowed between doses, and how long you need to take it will depend on the type of medication prescribed and on your condition.
While taking this medication, have your blood pressure checked regularly, as advised by your doctor.
While taking this medication, your doctor may tell you to take and record your pulse daily. Your doctor will tell you how rapid your pulse should be. If your pulse is slower than advised, contact your doctor or nurse about taking your calcium channel blocker that day.
