- Guaifenesin protocol
Guaifenesin protocol is an experimental, alternative treatment for
fibromyalgia proposed in the 1990s by DrR. Paul St. Amand . The proposed treatment involves three parts: titrating to the properguaifenesin dosage, avoidingsalicylate s, and following alow-carbohydrate diet if the patient ishypoglycemic .Guaifenesin has not been approved by the FDA for the treatment of fibromyalgia, and the protocol has not been shown to be effective in clinical trials as of 2008. It has been adopted by many due to anecdotal evidence of success; however a clinical study in 1996 has cast doubt on the effectiveness of Guaifenesin.cite journal |author=Bennett RM, De Garmo P, Clark SR |title=A Randomized, Prospective, 12 Month Study To Compare The Efficacy Of Guaifenesin Versus Placebo In The Management Of Fibromyalgia |journal=Arthritis and Rheumatism |volume=39 |pages=S212 |year=1996 |url=http://www.myalgia.com/guaif2.htm |format=reprint |doi=10.1002/art.1780391004 Lay summary and report:

Guaifenesin dosage
The dosage is individually determined by slowly titrating the dosage up until a worsening of symptoms is noticed and there is a decrease of the
lesion s that can be palpated in themuscle s. Patients begin with 300 mg twice a day and increase from there. The guaifenesin should be pure guaifenesin and not a preparation including other medications.Avoiding salicylic acid
Salicylic acid in even tiny amounts blocks guaifenesin from binding in thekidney s. It is present in many drugs such asaspirin , Salsalate, Disalcid, Anacin, and Excedrin. Plants produce salicylic acid, so herbal medications must be avoided as well as plant oils, gels and extracts incosmetics and any product that touches the skin. These ingredients includealoe ,castor oil ,camphor , and mint. Any plants can be eaten, however, because the small amount of salicylic acid present in food is broken down in thedigestive system and tagged withglycine by theliver before reaching the kidneys.Treating hypoglycemia
Many symptoms of
hypoglycemia (or perhaps more aptly titled Carbohydrate Intolerance) are similar to fibromyalgia, and, while leaving hypoglycemia untreated will not hinder the reversal of the disorder with guaifenesin, the symptoms will continue to plague the patient. The only treatment is a life-long avoidance of simple sugars,caffeine ,starch y foods, and any other foods that causeinsulin spikes.Theory of fibromyalgia cause
This theory involves
phosphate accumulation in cells that eventually reach a level to impede the ATP process, possibly caused by a kidney dysfunction or missingenzyme that prevents the removal of excess phosphates from the blood stream. This theory posits that fibromyalgia is an inherited disorder, and that phosphate build up in cells is gradual (but can be accelerated by trauma orillness ).Calcium is required to buffer the excess phosphate when it enters the cells. The additional phosphate slows down the ATP process; however the excess calcium prods the cell to action. The causative mechanism in the kidneys is unknown.The phosphate build-up theory is said to explain the myriad symptoms present in fibromyalgia and provides an underlying cause, but remains theoretical; there is no clinical evidence that the phosphate build-up theory is correct, or that Guaifenesin protocol is effective.
Results of the only reported randomized clinical trial in 1996 found that guaifenesin had no significant effects on pain, other symptoms, or laboratory measures (serum and urinary levels of uric acid and phosphate) over 12 months in a sample of people diagnosed with fibromyalgia syndrome, The lead author of the study has suggested a number of reasons why some patients may have previously reported benefits on this protocol, concluding "Dr. St. Amand has unknowingly used guaifenesin as a powerful focus in a program of cognitive behavioral therapy, in which his empathy, enthusiasm and charisma were the real instruments in effecting a beneficial change." [cite web |author=Robert Bennett |title=Speculation as to the mechanism whereby some of Dr. St. Amand's fibromyalgia patients experienced improvement while taking guaifenesin |url=http://www.myalgia.com/Treatment/guaifspe.htm |date= |publisher=Fibromyalgia InformationFoundation |accessdate=2008-01-06] Dr. St. Amand has noted that the study did not control for salicylate use, and therefore did not study the protocol as a whole. He has recommended a follow-up study be conducted which controls for all elements of the protocol. [St. Amand, R. Paul.

History
This theory arose when Dr. St. Amand noticed that patients with fibromyalgia symptoms had an increase of tartar on the
teeth in the form of calcium phosphate. Crystals are also often found onurinalysis , which further points to calcium phosphate, and musclebiopsies show an increase of phosphate in thecytosol . Lesions of muscles,tendon s, andligament s can be felt by a method of palpation called mapping developed by Dr. St. Amand. These lesions are thought to be contracted cells forming a spastic area caused by an excess of calcium in the cytosol of the cells.The treatment was discovered serendipitously when the physician found that
uricosuric drugs for treatinggout also coincided with relief of fibromyalgia symptoms. Guaifenesin is mildly uricosuric but, unlike standard uricosuric drugs, has almost no side-effects. Dr. St. Armand therefore began to study whether guaifenesin might relieve the symptoms of fibromyalgia while causing fewer side-effects than other uricosuric drugs had caused.References
