When you have a cold, your nose is blocked and you can't breathe, isn't it very annoying? Or sometimes your nose runs like water. Especially for young children, it's very difficult, they can't eat or sleep properly. So at times like this, a doctor can prescribe a syrup for you or your baby. Today we're talking about Pseudoephedrine, a medicine that is commonly used for things like nasal congestion and runny nose.
Simply put, what is Pseudoephedrine?
Pseudoephedrine is a drug that belongs to a class of drugs called decongestants . Imagine that when you have a cold, the tiny blood vessels inside your nose swell. That swelling is what causes your nose to get stuffy, your sinuses to tighten, and your head to feel heavy.
This medicine works by reducing that swelling, relieving the congestion inside your nose, and helping you breathe easier. Therefore, this medicine is used to treat conditions like nasal congestion, runny nose, and sinus pressure.
