Hello everyone! I am 22 years old and for the past few days I have been suffering from cough and cold with nasal congestion which is very bad. In fact, I am having difficulty in breathing. Today only I went to the doctor who has prescribed me phenylephrine as a nasal decongestant. Before I use it I would like to know as to how effective is phenylephrine as a nasal decongestant? Also tell me how it acts?
