You know the trouble that comes with a cold, whether you or a little one in your house. A runny nose, constant sneezing, a stuffy nose and difficulty breathing... These things can make you feel incredibly uncomfortable. So, at a time like this, a doctor might prescribe you this syrup. Today, let's talk about what this medicine is, what it does, and the things you need to be careful about when using it.
What really happens with this medicine?
Simply put, this is a combination of two medications. That is, Chlorpheniramine and Phenylephrine.
1. Chlorpheniramine: This is an antihistamine . Imagine, when we have an allergy, our body produces a chemical called histamine. This is like an 'alarm' that goes off at an unnecessary time. The runny nose, itchy eyes, and sneezing are caused by that alarm. So this medicine works by reducing the activity of that alarm and controlling those symptoms.
2. Phenylephrine: This is a decongestant . When you have a cold, the tiny blood vessels inside your nose swell and become larger. That's when we feel like our nose is blocked. This medicine works by causing those blood vessels to shrink a little, opening up your airways again.
The important thing is that this medicine only controls your symptoms (runny nose, stuffy nose). That is, it does not cure something like a bacterial infection. It is like raising an umbrella when it is raining. It stops the wetness, but it does not stop the rain.
