Are you or someone you know going into surgery? Or maybe you're seriously ill and need to be put on a ventilator to help you breathe. In these cases, doctors use a special medicine to temporarily relax your muscles. Vecuronium is one such medicine. This is not a medicine you can buy at a regular pharmacy, but a special medicine that is only given in a hospital. So, let's talk about this in a little more detail.
What exactly is Vecuronium?
Simply put, Vecuronium is a drug that temporarily relaxes the skeletal muscles in your body. It has two main purposes.
1. During surgery: The muscles in the body relax to make it easier for surgeons to operate. This allows the doctor to operate more easily.
2. With a ventilator: When someone is connected to a ventilator, this medicine helps the body work in synchrony with the machine, without conflict.
The most important thing is that this medicine will not make you unconscious, and it will not relieve pain. That is, it is not an anesthetic. The anesthesiologist will give you separate medications to numb your body and relieve pain. This only works by relaxing your muscles.
Things you need to tell your doctor before giving this medicine
If you decide to have Vecuronium, your anesthesiologist will ask you a few questions. For your safety and your own, it is important that you tell your doctor this information accurately and without hiding anything .
| Situation you need to report | Why is that? (Importance) |
|---|---|
| Other illnesses you have | Be sure to mention any neuromuscular diseases, especially heart disease, kidney disease, liver disease, lung disease (such as asthma), or myasthenia gravis. |
| Changes in body salt levels | If a doctor has previously told you that your blood levels of calcium, magnesium, or potassium are low or high, tell them. |
| Dehydration or burns | If the body is dehydrated or has extensive burns, the way the medicine works may change. |
| Allergies | Be sure to mention any allergies to vecuronium, bromide, or any other medicine, food, or dye. |
| Pregnancy and breastfeeding | It is very important to inform your doctor if you are pregnant, trying to become pregnant, or breastfeeding. |
How is Vecuronium given to the body?
You won't be able to use this medicine at home. When you're in a hospital or clinic, a trained doctor or nursing staff will give it to you either as an injection or through a saline infusion . So they have precise control over everything, including the dosage and the speed at which it's given.
Do you give this to small children?
Yes. In some special cases, this medicine can be used on babies as young as 7 weeks old. But it should be done very carefully and under the supervision of a pediatrician.
What if I take too much medicine?
This is given in a hospital, under the full supervision of doctors, so the chances of that happening are very low. If there is any suspicion that something like that has happened, the medical staff takes the necessary steps immediately. Also, there is a place where we can talk at any time in case of any drug-related problem. That is the National Poisons Information Centre at the Colombo National Hospital . In case of any emergency, it is also mandatory to inform the hospital's Emergency Treatment Unit (ETU).
Other drugs that may interact with Vecuronium
If you are already taking other medications, it is very important to tell your doctor about them, as some medications can interact with Vecuronium.
| Type of medicine | Examples |
|---|---|
| Some antibiotics | Gentamicin, Kanamycin, Neomycin, Tetracyclines, Polymyxin B, Colistin etc. |
| Some medications used for anesthesia | Such as Enflurane, Isoflurane, Halothane. |
| Medicines containing magnesium | Magnesium, sometimes given through saline. |
| Other muscle relaxants | Other muscle relaxants used for surgery. |
| Quinidine | A medicine for irregular heartbeats. |
This list is not complete. So tell your doctor about all the medications you are taking, including vitamins, herbal remedies, and supplements. Also, tell your doctor if you smoke or drink alcohol.
What are the possible side effects?
Like any medication, Vecuronium can cause side effects. But because you are in the hospital, the medical team is prepared to manage any of these quickly if they occur.
| Side effect | Description |
|---|---|
| If you experience these symptoms, tell your doctor or nurse immediately. | |
| Allergic Reactions | Skin rash, itching, swelling of the face, lips or tongue. |
| Difficulty breathing | Difficulty breathing if you are not on a ventilator. |
| Low blood pressure | Dizziness, blue eyes, feeling like you're going to fall, feeling unusually tired. |

| If these symptoms persist or are bothersome, tell your doctor. | |
| Muscle pain | Muscle pain that persists even after the effects of the medication wear off. |
| Muscle weakness | Unusual physical weakness that persists even after the effects of the medication wear off. |
