What is Poly-Vent IR?

There are numerous varieties and brands of guaifenesin, in addition to pseudoephedrine, available. Not all brands are mentioned on this leaflet. Guaifenesin can be described as an expectorant. It assists in easing congestion from your throat and chest, which makes the process easier for you to cough out of your mouth.

Pseudoephedrine, a decongestant, reduces blood vessels within the passages of the nasal airways. The blood vessels are dilapidated, which can cause the nasal passages to become congested (stuffy nasal congestion). Poly-Vent IR is a mix medicine that is used to treat sinus congestion and stuffy nose as well as to lessen chest congestion that is caused by the typical flu. Poly-Vent IR can also be used for other purposes that are not covered in this guideline for medication.
