It's very annoying when we have a cough or a cold. So, there are times when we go to the pharmacy and ask for a single medicine that will cure several of these symptoms in the hope of a quick cure. Such medicines are often made by combining them in a way that will cure all three: cough, phlegm, and nasal congestion. Although it may seem simple, it is very important to know what is in the medicine we take and how it affects our body. Today we are talking about such a commonly used combination of medicines.
What does this medicine contain?
This medicine is actually a combination of three main types of medicine. Each of them does a different job. Simply put, these three medicines work together to control your cough, phlegm, and nasal congestion.
- Dextromethorphan: This is a cough suppressant. It works by affecting the cough center in the brain, stopping frequent, painful coughs.
- Guaifenesin: This works by loosening mucus in the chest and helping it to be coughed up more easily (expectorant). This greatly reduces the discomfort of mucus stuck in the throat.
- Phenylephrine: This works by constricting the blood vessels in the nose, reducing nasal congestion, runny nose, and congestion (decongestant).
Important: This medicine only controls symptoms. If you have a bacterial or viral infection, this medicine will not cure it.
