You may have been prescribed a medication by your doctor for a condition like lupus. If so, you may have heard the name `Belimumab`. Today, we will talk about what kind of medicine this is, how it affects our bodies, and what we need to know about it. Let's try to understand it simply, as if a friend were explaining it to you.
What kind of medicine is Belimumab?
Simply put, Belimumab is a drug that is used to treat certain conditions, such as lupus. You know, our bodies have something called the immune system. This is like a bodyguard that protects us from disease. But, in conditions like lupus, this immune system becomes overactive and starts attacking our own body cells. It's like our own bodyguard is fighting with us.
That's when this drug called `Belimumab` comes to the rescue. It belongs to a class of drugs called `monoclonal antibodies`. What this drug does is to slow down the overactive immune system and control it. Then, the inflammation and swelling that occur in the body are greatly reduced. It can be found in the market under names like `Benlysta`.
However, doctors may use this medicine for other conditions as well. So if you have any questions, it's best to ask your doctor or pharmacist.
What should I tell the doctor before taking this medicine?
Before you start taking Belimumab, it's important to tell your care team some important information. This information will help them decide whether or not this medicine is right for you, and what precautions should be taken.
If you have any of these situations, be sure to tell us about them:
- If you have cancer or have had it before.
- If you have a condition like depression .
- If you have other problems with your immune system .
- If you currently have an infection (such as fever, cold, cough).
