My allergist recommended long-term use of this product, and this is the most economical form (quantity) I was able to find. Be aware that it is NOT a timed-release formula, as is the most common over-the-counter form in this dosage. It seems to be working well, after more than 6 months of use.

I use this fast acting guaifenesin for the thick phlegm which comes up after I use my inhalers.
