Are you saying the FDA wants to ban Guanfenisen also? Hope not.
Guaifenesin is an ingredient in cough and cold medicines that is used to help clear mucus or phlegm from your chest when you have had a cold or flu.
The spelling is a little different, but I think they are the same med.
What are the common brand names?
You are correct, I spelled it wrong. And I am starting to think I dreamed that guaifenesin was on the FDA ineffective list as I can’t find the article that I thought I read.
I will try to find it tomorrow, it has been a long day. Sorry for the confusion and/or bad info.
Guaifenesin is labeled as an 'expectorant', it breaks up mucus congestion in the chest, especially the bronchial tubes. I keep a constant supply on hand, having had bronchial pneumonia once. The most common symptom of bronchial congestion is a persistent cough with some throat irritation. Phenylephrine is a vaso constrictor which may have led to its reputation as a decongestant. For my part I have taken it as a temporary decongestant in conjunction with a longer acting (24 hour) decongestant/antihistamine such as loratidine (Claritin) or fexofenadine (Allegra - which has worked best for me.)
I suspect that Phenylephrine has enjoyed some favorable acceptance due to confusion with Pseudoephedrine, a more effective decongestant. It is combined with loratidine (Claritin-D) and fexofenadine (Allegra-D), but their availability is somewhat restricted because Pseudoephedrine is used to make methamphetamine.
I think that Phenylephrine started with Claritin or with Allegra has helped me get a faster decongestant effect with severe congestion but I found little effect over long term repeated dosing. If anyone knows of a fast acting short term decongestant let me know (chlorpheniramine maleate is one.) Long ago there was Contac capsules but they were so effective that they had to be rushed off of the market. They contained small amounts of atropine - a heart stimulant, scopolamine - used as a truth serum before sodium pentothal and hyosyamine, a drying agent. Before they took it off of the market I bought as much as I could afford; of course the effective life expired somewhat quickly -- something I have found true of Allegra and Claritin also. 😥
