Fast acting (FA) guaifenesin
, should ONLY be used in conjunction with long acting (LA), also known as extended release guaifenesin.  Fast acting guaifenesin should, according to Dr. St. Amand, ONLY be added to guaifenesin protocol, when the daily intake of LA, long acting, guaifenesin, is at least 1800 milligrams.

Only long acting/extended release guaifenesin will stay in your bloodstream long enough to enable the effects of guaifenesin.
