Have you ever felt uncomfortable when your heart rate suddenly accelerated or did not beat in a regular manner? Perhaps someone close to you, your mother or father, has been hospitalized because of this. In such cases, a special injection called Verapamil is used by doctors to restore the heart rate to normal. Since this is a medicine given in an emergency, it is normal to feel a little scared and curious about it. So today, we will talk about this Verapamil injection very simply, in a way that you can understand.

What exactly is Verapamil?
Simply put, Verapamil is a medicine that is used to control a fast or irregular heartbeat (arrhythmia). It belongs to a class of drugs called calcium channel blockers.
Think of your heart as a pump that works constantly. Sometimes this pump starts working too fast. Or it stops working in a rhythm. The Verapamil injection controls the entry of calcium into the heart cells. This slows down the heart rate and reduces the workload on the heart. In other words, it calms down the overactive pump and allows it to work normally again.
The important thing is that this is not given as a pill, but as an injection into a vein by a doctor or nurse in a hospital or clinic.
Things you need to tell your doctor before giving this medicine
Before you are given Verapamil, your doctor will need to know your complete medical history . This is because some conditions require special care when using this medicine. Be sure to tell your doctor if you have any of the following conditions:
| Illness or condition | Description |
|---|---|
| Heart disease | If you already have heart disease, heart failure, an irregular heartbeat, a very fast heartbeat, or low blood pressure. |
| Other medical conditions | If you have liver or kidney disease, a brain tumor, or a muscle-weakening disease such as Duchenne muscular dystrophy. |
| Allergies | If you have previously had an allergy to verapamil or any other medicine, food, or dye. |
| Special occasions | If you are pregnant, trying to get pregnant, or breastfeeding. |
How do you use this medicine?
As I said before, this is not a medicine you can take home.
- This is an injection that is given into a vein under the supervision of a doctor in a hospital or clinic .
- This medicine can be given to newborn babies in some special cases, but it should be done with great caution and under special medical supervision.
- Overdose: This is given in a hospital setting, so the chances of this happening are low. However, if you suspect that you have overdosed, you should immediately inform the medical staff. Usually, in such cases, you should immediately go to an ETU (Emergency Treatment Unit) or, if necessary, call the National Poisons Information Center at the Colombo National Hospital for advice.

What should you expect when taking the medicine?
While you are being given this medicine, the medical staff will constantly monitor your condition, especially your heart rate and blood pressure .
