Do you also have a very difficult time with a stuffy nose, sneezing and coughing all the time? When we go to see a doctor, we often get this kind of medicine. It usually comes in the form of a syrup. So today, let's talk about what this medicine really is, what it does to our body, and what we need to be especially careful about when using it.
What really happens with this medicine?
Simply put, this is a combination of three medications. Each of them does a different job. Think of it like giving three answers to three questions in one place.
- Antihistamine: Dexchlorpheniramine is a type of antihistamine that helps control allergy symptoms such as sneezing, runny nose, and watery eyes.
- Cough suppressant: The dextromethorphan component in this works by suppressing the cough center in the brain, stopping the annoying dry cough.
- A decongestant: This contains pseudoephedrine, which constricts the blood vessels inside the nose, reducing nasal congestion and sinusitis, making it easier for you to breathe.
But one thing is important to remember. This medicine only controls the symptoms. It does not cure a viral or bacterial infection in your body. It is like raising an umbrella when it is raining. It stops the wetness, but it does not stop the rain.
