Guaifenesin Sources    
22 January, 2008


Guaifenesin is pronounced 'gwy-fen-e-sin' - the "e" between "fen" and "sin" should be pronounced like the "e" in "item".  On GG it is known affectionately as guai ('gwy') and those following the Guaifenesin protocol, are called Guais (i.e., Gwys), a little play on the word 'guy'.

FDA Proposes Steps to Assure the Safety and Efficacy of Certain Currently Unapproved Medicines

ALL Guaifenesin is appropriately manufactured

Q: Is Asian guaifenesin a problem?

A: This is one of those queries that come up from time to time, seemingly based on past concerns when answers were being sought to the failure of some guai’ers to progress, as expected, on LA products. GG research indicated that the reason for this was most likely ‘people respond differently because they are different people’ and opinion provided by pharmacists, at that time, did not support the notion that Asian ‘raw’ product was the problem. More recently, an Australian compounding pharmacist responded:

"Thank you for the opportunity of commenting on guaifenesin. I would say that we must distinguish between the active ingredient (i.e., Guai raw material ) and the finished product (capsules and tablets). This is because most of the Guai active comes out of Asia, principally Taiwan and China and we have no real knowledge of their quality control. For that reason, I would have to say that it is better if the Guai finished product comes out of the USA, Australia or another country where the manufacturers of the capsules or tablets have met the stringent requirements of the FDA*, the TGA, or equivalent governing body, no matter what the source of the raw material. This requires that the manufacturer meets those requirements like auditing the suppliers of the active ingredient, no matter what its source, test it for potency and purity and manufacture the finished dose from within an appropriately licensed and inspected facility. This, of course, means finished product testing and greater assurance in product quality for the consumer."  Antony Accordino

FDA guidelines

All legally manufactured single-ingredient guaifenesin, whether immediate-release or extended-release, is FDA-approved. No approval has a higher status than another, with regards to guaifenesin (Gregory K. Penniston, D.C., Pg, 62, The Guaifenesin Guide - Out of Print.  Please see the new edition titled, Fibromyalgia, Chronic Fatigue & Irritable Bowel: Treating Symptoms Treating Cause By Gregory K. Penniston, D.C.  In this book Dr. Penniston explains how and why the different treatments that are commonly used can be of help. He also explains that these treatments are limited because they do not treat the underlying cause of these conditions. The little known medication, guaifenesin, does appear to treat the underlying cause in many people. Dr. Penniston explains why guaifenesin works and how to best use it.

Acceptable Guaifenesin Compounds

Below: All these Guaifenesin compounds are acceptable for the protocol - use the appropriate one for your particular circumstances. 

The Guai-Support list has elected to use these terms for abbreviation:


Long-acting = LA

(Pharmaceutical terms: ER = extended-release, SR = sustained-release)


Quick-acting = QA

(Pharmaceutical terms: RR = regular-release, IM = Immediate-release)


Quick-acting/Long-acting Combination = Q+LA

Long-acting Compounded Capsules = LACC


Quick-acting Compounded Capsules = QACC

(Many people have difficulty taking tablets. Maybe you are throwing your head back to help with swallowing. A member recently informed us that she read in an old folk remedy book that the best way to take pills is to actually tuck your chin down towards your chest, instead of throwing back your head. When you drink your water, the pills slide down much easier.)

Quick- acting Compounded Topical Cream = QACTC


Quick-acting Home-made Topical Lotion = QAHMTL

(Click here to see Rowena's recipe)

Measuring out & dosing topical guai:

There  have been reports that the responses differ between types of guai taken, e.g., less topical (QA) guai is needed to invoke the same response as a QA tablet and less encapsulated QA guai is needed to invoke the same response as a QA tablet.

There is no way to calculate an "equivalent" dose when switching from tablets/capsules that are swallowed, to a topical preparation. You will need to start again from the beginning, with a low dose and slowly increasing until you reach a point where you think it's having an effect.

When you order your topical guai from a compounding pharmacist, ask she/he if s/he would prepare it in a hypodermic syringe MINUS the needle. The plastic tube has measuring marks on it. The dosage marks are easy to read and the plunger just has to be moved carefully to expel your dose X 2 daily.  A small cap covers the place where the needle would be and where the cream comes out when you squeeze the plunger.  If for some reason your pharmacist won't do it (although I'd be surprised), you have already purchased your cream or you are making it at home you can purchase the syringes and insert the cream yourself.

Work out something that is convenient to you, and stick with it. Maybe squeezing out 1mm, or 5mm or whatever, of gel onto your finger will be something you can cope with - you could do it over a ruler for greater accuracy. Don't concern yourself with calculating just how much guai is in the portion you squeeze out of the tube and apply to your body, but do watch that you are consistent with how much you use on each step of the titration process.

Compounding Pharmacist Antony Accordino wrote in response to my question regarding the action of compounded long-acting capsules:

July 6, 2006

"The anatomy of the digestive system
Stomach empty in 2 - 6 hours with 10% absorption
Small intestine empty in 3 - 5 hours with 10% absorption
Large intestine empty in 3 - 10 hours with 10% absorption
Total = 8 - 21 hours
Average = 14 - 15 hours

My experience is that slow release for capsules is somewhere between 6 to 8 hours. Tablets can be different in that the hydrophilic matrix can be better controlled and the dissolution time extended further.

The key is gut transit times and this can vary widely due the various reasons such as diet, health, genetics etc"

LA or QA Guai:  Which Kind is Right for Me?


Gel capsules sizes: #0 = 300mg -- #00 = 600mg

1) Pure Guaifenesin LA or QA capsules of any strength 
2) Pure Guaifenesin tablets of any strength

LA, QA or Q+LA

3) Pediatric sprinkles are no longer in production.

To work around this, use pure powder and mix with jelly/jam as guai is very bitter. 1/8 tsp = 300mg; 1/4 tsp = 600mg

4)  Sugar and alcohol free Liquids
5) Pure Guaifenesin Powder

(pack or have packed for you (can be compounded to LA or left QA)

7) Topical Guaifenesin

(a recent innovation) Tom Slaughter of Mulberry Compounding Pharmacy assures us that guaifenesin is absorbed through the skin.  Several people are known to be using it and all of them are cycling on it at a dose lower than their previous long-acting dose.  There may be other compounding pharmacies in your own area willing to order Guai powder and make up capsules or topical cream for you.  One member makes her own.

8) Compounded Guai (Be sure to state on the prescription the reason you need especially compounded Guai, e.g. sensitivity to dye, you need to split  your dosage and Mucinex is difficult to break, etc.)

Important Information

We have had complaints, from individuals, about a number of brands of guai, demonstrating the individual nature of responses to any product.   Please click her to read our  Guai Product Troubleshooter Report for more information.  It also contains information regarding some people experiencing stomach pain when taking guai.


Calcium binds to phosphate as calcium phosphate and, added to meals (Tums, etc.) may be carried out of the body via increased fecal elimination.  This may also allow for lower doses of guaifenesin and one could experiment if so inclined.


Free Drug Program


The Guaifenesin (eexpectorant) protocol we follow & discuss uses a synthetic chemical compound. 


Guaifenesin is an expectorant, which loosens and thins mucous, not a  decongestant.  Decongestants can raise BP and require great caution if used with history of elevated blood pressure (labels may indicate this).  According to the literature, there is no need to be concerned about guaifenesin raising BP.


Do not take Guaifenesin in combination with something else such as Dextramethorphan (cough suppressant [e.g. Mucofen], [further reading], or Pseudoephedrine (decongestant) unless specifically & knowingly RX'd by your doctor for a condition other than FMS.   If it's necessary to take Liquid Guaifenesin for a particular reason appropriate ones are listed below.


Do not use Entex LA unless specifically RX'd by your doctor for reasons other than FMS.   It is not pure guai.  It contains Phenylephrine as the decongestant. ( It used to contain 75 mg. of Phenylpropanolamine Hydrochloride, which is a decongestant that can raise blood pressureand only about 200 mg of guai.) 

We have no information on how people do on Guaiacum homeopathic Guaifenesin (Botanical: Guaiacum officinale (LINN.) Family: N.O. Zygophyllaceae), nor the Guaiacum Wood, but they are listed here for those interested in investigating and/or experimenting with them.  More on Guaiacum officinale.


Guaifenesin has a short half-life, which is why it is recommended that we take it in divided doses instead of just once every 24 hours.

Some Guaifenesin tab's have a tiny amount of green/blue dye which we see no problem with as many tablets contain dyes.....even white ones.  If you are concerned about allergies however please check out products without dye.


If you purchase guaifenesin LA (long-acting) and wish to keep it that way don't crush or chew tablets as it interferes with the long acting capability.   You can & should do all the above if you wish to make your LA Guai QA (quick-acting).  For more information regarding products please click here.  There is no scored LA on the market at the time of this writing (05/02/14)


The uricosuric action of guaifenesin was found many years ago however it is not common knowledge, and there is no label warning on any guai product, that Guaifenesin has the ability to alter uric acid test results which may cause problems for those with gout.


Guaifenesin can falsely elevate the results of laboratory tests for vanillylmandelic acid (VMA), which is the main urinary metabolite of catecholamines (adrenaline and noradrenaline). In addition, it is well known that guaifenesin can cause false positive results in tests for the serotonin metabolite, 5-hydroxyindoleacetic acid . You should stop taking guaifenesin 48 hours before giving urine for either of these tests.


(By the way, aspirin also interferes with VMA and 5-HIAA tests. Ephedrine and caffeine cause increased values in 5-HIAA tests. Foods that are high in serotonin (avocados, bananas, eggplant, pineapples, plums, and tomatoes) can also cause false positives in 5-HIAA tests. An awful lot of foods and even artificial coloring and flavoring can cause false positives on a VMA test.)


Guaicum: Treatment for Symphilis (borellia, a spirochete - the bacteria that causes Lyme)

Guaicum Treatment for Syphilis
Syphilis is a special type of bacteria that is similar to borellia (the bacteria that causes Lyme) in that it is a spirochete. Given the connection in symptoms between lyme and fibromyalgia, it is very interesting that guaicum was considered a treatment for syphilis.

Aside from the connection in symptoms, this also seems to point to the possibility that those with fibromyalgia may have a spirochetal infection which may be why guai is effective for some people. New spirochetes are still being discovered.

There were originally no effective treatments for syphilis. The most common in use were guaiacum and mercury: the use of mercury gave rise to the saying "A night in the arms of Venus leads to a lifetime on Mercury". Though no proper studies were done to prove it, mercury may have been an effective means to treat syphilis.


Problems with Medications

If you notice a change with a medication, contact the manufacturer (compounding pharmacy or pharmaceutical company) immediately and then follow up with your doctor if the medication is found to be remiss in any way. An unexplained change of any kind (e.g., color change, swelling or a different smell) could indicate that the product has undergone some sort of chemical reaction. This can happen from heat or moisture and, although it is wihin the the correct date, the above changes may have caused expiration.

It is fine to purchase from independent pharmacies (that are not chains). They often cater to those needing special compounding because large corporations do not feel it is worth their time. If you order from out of state and are not able to view certificates, check pharmacy boards as they often have licenses listed on their web sites. If you cannot find the information on-line call them and inquire if it is licensed in that state. They should be able to direct you to legitimate confirmation.


Storing Guaifenesin

Bonny's Storage of Guaifenesin Tips

Heat and/or humidity can affect the efficacy of medications so store your guai properly, and buy from sellers you trust to do the same. 
-Store guai between 59 & 86 degrees F and
l5 & 30 degrees C.
-Do not store in the refrigerator or freezer.
-Store away from heat and direct light.
-Do not store in the bathroom, near the   kitchen sink, or in other damp places. Heat or moisture may cause the medicine  to break down.
-Do not leave the cotton plug in a medicine container that has been opened; the cotton may draw moisture into the container.
-Do not leave the cap off the bottle 
- Fludan state that that if their Guaifenesin powder is 'fly away' or 'staticky' to put it in the freezer for 1 hour ONLY before packing into capsules.


Dolores' sent this storage tip: A gardening show host, who was giving tips on how to store seeds over the winter, took 2 teaspoons of powdered milk, put them in a double sheet of paper towel, put them at the bottom of a plastic container, put the seeds in, put the lid on and then stored the container in a cool dry place. Apparently there is something in the powdered milk that draws all the moisture out.

Splitting Capsules and Tablets Into Smaller Strengths

Guaifenesin Manufacturers/Brands
If you cannot purchase Guaifenesin in your own country please check with your authorities to see if you can import enough Guaifenesin for personal use and if you need an RX to do so.  Also check your compounding pharmacists who can assist you with compounding guaifenesin in any format/dose.

All previous LA are now unavailable (since November 2003) until the manufacturer seeks an NDA or ANDA.  All QA (quick-acting, regular-release) continues to be available over-the-counter, although not many are available in local drugstores/chemist shops.  Look to Compounding Pharmacists if you require long-acting Guaifenesin other than those listed below.  Compounding pharmacists have separate rules than mass producers so guaifenesin can still be compounded in any requested formats/doses. 


Much discussion has taken place regarding the efficacy of the products listed below.  You will find those discussions in the GG archives.

Canada Guai Availability UPDATE:
Current events do NOT apply to US or International customers - it only affects Canadian customers.

For the moment, Fludan Fine Chemicals is still not allowed to sell bulk guai directly to individuals in Canada (see announcement below). They are however, allowed to sell to doctors and pharmacists who are then allowed to sell to individuals. Dr. Sean Ceaser from Winnipeg, Manitoba has agreed to be a distributor in Canada. He has been following the guaifenesin protocol for about 3 years. He can be reached at 204-831-6125  or by email

Latest update from Fludan Fine Chemicals, July 2003: "We were told by health canada that a DIN would be one way to continue, but as we research it - it turns out to be a very expensive and almost an impossible route. It had sounded great at the time but little was explained to us about the procedures. So for now we are grateful Dr. Ceaser has decided to help us in this matter as we can only sell to pharmacies or Doctors. Luckily he has been following the protocol for about 3 yrs and knows it works. If ever we are again able to sell directly to the public we will announce it on all the sites. Thanks again.

Original announcement from Fludan Fine Chemicals, May 2003. "We have been advised by Health Canada that we will require a DIN (drug identification number) to continue to sell Guaifenesin in bulk in Canada. We have will have suspend our sales of Guaifenesin in CANADA for the next couple of months depending on the duration of time it takes for the DIN to be approved. This though does not affect our US or International sales, it only affects CANADA. Unfortunately, we have just been made aware of these new specifications and we only have a couple of days left to continue selling guaifenesin in CANADA. We are sorry for the inconvenience this will cause our Canadian clients."

Garden Pharmacy is no longer able to supply Guaifenesin

From: "Harry Ganz" <sales@garden.co.uk>
Date: Tue, 4 Feb 2003 16:05:51 -0000
To: "name withheld>

Subject: Guai

Unfortunately, due to controls by the Pharmaceutical Society, we have immediately stopped the supply of Guai tablets.

This is beyond our control, and unfortunately, it looks as if we are going to be prosecuted for supply of unlicensed medical products.

The Pharmaceutical Society also claim that the drug is totally ineffective in the treatment of fybromyalgia, which is another reason for the prosecution.

I am sorry for any disappointment this will cause.

Natural flavours are fine as an inactive or additional ingredient in a supplement as long as it is not mint or peppermint. The exception is if it's used in a product that is held in the mouth like a lozenge or toothpaste then it's likely a problem and should be avoided. Stevia used as a sweetener is unlikely to block.

GuaiCare  QA - LA - Compounded guaifenesin

"By using a topical product, you eliminate the first-pass effect and more drug gets into the blood. A much smaller amount of topical gel is therefore required. New data show that one gram (100mg) of GuaiCare Topical 10%TM may be equivalent to an 400mg dose of oral guaifenesin.

Finally, many patients using the guaifenesin protocol may dislike the many “ups and downs” associated with phosphate cycling. A topical gel allows them to dose themselves in small increments throughout the day to avoid the hard painful cycling associated with oral tablets."

GG: Thus, if you have 100mg of cream, and it contains 10% guai, then there would be 10mg guai in that 100mg of the cream.

 Zero Limits: The Secret Hawaiian System for Wealth, Health, Peace, and More

"This riveting book can awaken humanity. It reveals the simple power of four phrases to transform your life. It's all based in love by an author spreading love. You should get ten copies of it----one for you and nine to give away. It's that good."
---- Debbie Ford, New York Times bestselling author of The Dark Side of the Light Chasers

After 13 years of illness, some good things are happening, and I'm finally on my way to being totally well.  Books that set me on this path are:

Fibromyalgia, Chronic Fatigue & Irritable Bowel: Treating Symptoms Treating Cause

By Dr Gregory K. Penniston
(The re-titled new edition to
The Guaifenesin Guide)

A unique book that gives sufferers and their families clear explanations and practical information on every type of treatment for these distressing and hard to manage disorders. It dispels the misconceptions, that lead some people to dismiss these conditions, with thoughtful explanations and reasoning. This book gives emphasis to eliminating the conditions by addressing their 'cause', with a commonly used 'over-the-counter' medication, guaifenesin and provides detailed, easy-to-follow guidelines.





Examining Guaifenesin




Parting the Fog: The Personal Side of Fibromyalgia/Chronic Fatigue Syndrome

By Sue Jones, a GG Member

Parting the Fog" is a candid, first person account of what it is like to walk in the shoes of someone suffering from fibromyalgia/chronic fatigue syndrome. It relays the seriousness of this condition in an easy-to-read manner, while employing humor and focusing on hope.







Crack Up at the Wake of Dawn: Everyday Poetry to Incite and Delight Your Soul

Another great Book from our GG Member Sue Jones!  If you are a fan of "Parting the Fog", you won't want to miss this book. Although it isn't specific to fibro, you WILL find chapters you can closely relate to, since many topics are dealt with. Some of the poems may make you cry, others make you laugh, and still others trigger a thought or give you greater insight. Whichever the case, you won't be left unaffected.









Take My Hand: The Extraordinary Story of a Girl Named Janis

In Take My Hand, Audrey Revell (a long time member of GG) paints a vivid and moving picture of the life and indomitable spirit of her daughter Janis, an exceptionally talented musician and composer despite having lost her sight as a child together with progressive hearing loss.
