Immediate relief from chest colds.

I have been using Musinex for a quite a long time. My Dr. Is the one who recommended it to me.It works great for chest colds. I have told quite a few people about it and they are using it too.

Reliable and Long-lasting Relief

Because I don't have allergies, I don't need or want a product full of anti-histamines when I have some throat congestion. This is just guaifenesin with an extended release layer so it provides extended relief to my throat.

Mucinex to the rescue

I have found that this product will help in stopping sinus problems. It must however be start as soon as you notice the first sign of a problem - sneezing, coughing, watery eyes and runny nose.
