Has your doctor prescribed you a shot called Vasopressin? Or is someone close to you taking this medication? Hearing this name may sound a little strange, and you may even feel a little scared. But don't worry. It's important to be properly informed about any medication. Today, let's talk about this medication, what it does to our bodies, and what to be careful about when using it.
What is Vasopressin?
Simply put, Vasopressin is a hormone naturally produced by the pituitary gland in our brain. Another name for it is antidiuretic hormone, or Antidiuretic Hormone (ADH). The vasopressin given as a medicine works in the same way as this natural hormone in our body.
So this does two main things inside the body:
1. Reducing urine output: One of the main functions of this hormone is to affect the kidneys and reduce the amount of urine excreted from the body. That is, it helps the body retain water.
2. Narrowing of blood vessels: It can constrict, or narrow, the small blood vessels in the body.
Because of this mechanism of action, doctors use this drug mainly for several conditions:
- For Diabetes Insipidus: When you hear this, you may think of the diabetes mellitus we all know. But this is a completely different condition. In this disease, excessive urination occurs either because the body does not produce the hormone ADH properly or because the kidneys do not respond to it properly. So this medicine is given to control it.
- Before and after certain surgeries: This medicine is also sometimes used to reduce gas (flatulence) in the stomach before or after surgeries.
Things you need to tell your doctor before taking medicine
Before you start taking this medication, there are a few things you should definitely tell your doctor. Don't hide these, because they are very important for your safety.
Giving your doctor a complete description of your health condition is essential to receiving accurate and safe treatment.
If you have any of the following conditions, be sure to tell your doctor:
- If you have heart disease or blood vessel disease .
- If you have allergies to Vasopressin or any other medicine, food, coloring, or preservative .
- If you are pregnant or expecting a baby .
- If you are a nursing mother .
How should I use the medicine?
This medicine is given as an injection under the skin (subcutaneous) or into a muscle (intramuscular). If you are going to give it at home, your doctor or nurse will show you how to do it and prepare the medicine. It is very important to follow the instructions exactly. Take the correct dose at the correct time. Never take more than prescribed.
Things to pay special attention to
- Disposing of needles: Never throw used needles and syringes in the trash. They should be placed in a special sharps container. If you don't have one, ask your doctor how to get one.
- For children: If you are giving this medicine to children, you should talk to a pediatrician about it. Although it is prescribed for children in some selected cases, there are some special considerations to be aware of.
- Overdosage: If you suddenly feel that you have taken more than the prescribed dose, do not delay. Immediately call the National Poisons Information Centre at the Colombo National Hospital , or go to the Emergency Treatment Unit (ETU) of the nearest hospital.
- If you miss a dose: Take the missed dose as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take your next dose at the scheduled time. Do not take two doses at once for any reason.
Things to keep in mind when taking medication
There are several important things you need to pay attention to when taking this medicine.
- Medical tests: Check your condition and see your doctor at the scheduled time.
