What is Benylin Mucus Cough With Decongestant Syrup?

Benylin Mucus Cough With Decongestant Syrup is a treatment that helps to relieve mucus coughs and also work as a decongestant to clear a blocked stuffy nose. This liquid contains two active ingredients that help to reduce the effects of a chesty cough. These are:

  • Guaifenesin
  • Pseudoephedrine

Guaifenesin is an expectorant that loosens the mucus that is caught in the chest, making it easier to be removed. Pseudoephedrine is a decongestant that helps to improve breathing by unblocking the nose and sinuses.


What is a mucus cough?

A mucus cough, also known as a chesty cough, is a type of cough that is caused when mucus or phlegm is caught in the chest or throat and this leads to a cough. It can also lead to a sore throat as well. A mucus cough usually isn’t present long-term but the right treatment can reduce its effects. The most common cause of a mucus cough is a cold or the flu. Both of these will come with other symptoms besides a cough.
