Verapamil injection is given as an infusion into a vein, usually in an emergency situation. A healthcare provider will give you this injection. Your heart rate will be constantly monitored to help determine when your heartbeats have returned to normal.
Oral verapamil is taken by mouth. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Do not use the injection if it looks cloudy or has particles in it. Call your pharmacist for new medicine.
Swallow a capsule or tablet whole and do not crush, chew, break, or open it.
Your blood pressure will need to be checked often. Your liver function may also need to be checked.
If you need surgery, tell the surgeon ahead of time that you take verapamil.
If you have high blood pressure, keep using this medicine even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medicine for the rest of your life.
Store at room temperature away from moisture, heat, and light.
