Do you also feel like your chest is full of mucus when you catch a cold, and when you cough, it feels like it's blocked without any mucus coming out? At the same time, does your nose get blocked and you find it difficult to breathe? This is a really annoying experience. At times like these, there are medicines that provide a solution to both of these problems at once. Today we are going to talk about one such medicine.
What is this medicine called Guaifenesin; Phenylephrine?
Simply put, this is a combination of two medications. This is most commonly available as a syrup. Let's see what happens with each of these medications.
- Guaifenesin: This is known as an expectorant . This means that it works by thinning the thick, sticky mucus in your chest, making it easier to cough up . This reduces the feeling of tightness and heaviness in your chest.
- Phenylephrine: This is a decongestant . It works by constricting the swollen blood vessels inside your nose, which can help reduce nasal congestion and make it easier to breathe . It also helps control the flow of mucus.
But one thing to remember is that this medicine only controls your symptoms (phlegm, stuffy nose). It does not cure an infection like the virus that caused your cold .
