desiccated thyroid tags

When Forest Labs reformulated Armour earlier this year, they stated they increased the filler Microcrystalline Cellulose, and decreased the Sucrose (sugar). The tablets became impossible to do sublingually, and you have to wonder why they would change a quality that patients praised so heavily.  Positive opinion among patients for Forest Labs slipped several notches.

But the real cuckoo’s nest for many thyroid patients, who knew firsthand the life-changing benefits of natural desiccated thyroid, was a maddening return of serious hypo symptoms on the new Armour and subsequent new stress on their adrenals, sooner…or later! You can read several horror stories in the comments of the post below, or go here.

So patients turned to other alternatives: Naturethroid and Westhroid by RLC Labs…then when the desiccated thyroid shortages hit in the Fall of 2009, Erfa’s Thyroid, Compounded desiccated thyroid, and others. And there have been problems for some patients on most everything they switched to.  The LEAST problematic has been Erfa’s Thyroid, and the most problematic was Compounded.

So what has been the common thread in the most problematic desiccated thyroid products? CELLULOSE, a plant fiber, and more commonly known by the trade name Avicel. And what does fiber do in your stomach? Inhibits absorption. Armour’s cellulose was raised, and bamm…problems.  Compounded desiccated thyroid, with cellulose as a filler, has been problematic for many patients with a return of hypo symptoms,  especially if  it was Methyl Cellulose, a larger particle size product. But some have even had problems with compounded containing Microcrystalline Cellulose, the smaller cellular product. And a certain body of patients even had problems with Naturethroid before it became scarce. And Naturethroid uses cellulose as a filler.

Is this problem true with T3-only products? Yup. Patients have noted that generic T3 is far less effective than the brand name Cytomel (both Liothyronine Sodium)  And what filler it up to 70% in the generic T3?  CELLULOSE.  See the percentages here for Paddock’s generic T3.

Why have less problems been reported with Erfa’s Thyroid? Perhaps because it has no cellulose as a filler! See this list of ingredients, which STTM has been working on lovingly for a few years.

What does literature say about the use of Cellulose as a filler in medications? Plenty. Cellulose is from wood. Wood is fiber. And fiber in your gut affects absorption. From http://www.umm.edu/altmed/articles/fiber-000303.htm we get this:

* Dietary fiber has been reported to lower the blood levels and effectiveness of tricyclic antidepressant medications…Reduced dietary fiber intake increased the blood levels and improved symptoms in these patients.

* While fiber supplements may help to regulate blood sugar levels, they may also interfere with the absorption of anti-diabetic medications….Therefore, fiber supplements should not be taken at the same time as these medications.

* Taking soluble fiber such as psyllium with carbamazepine (Tegretol), a medication used to treat seizure disorders, may decrease the absorption and effectiveness of carbamazepine.

* Fiber in the form of pectin (from fruit) and oat bran reportedly reduces the body’s ability to absorb cholesterol-lowering medications known as “statins,”… and could lead to decreased effectiveness of these medications.

* Fiber supplements may reduce the body’s ability to absorb digoxin (Lanoxin), a medication used to regulate heart function.

* Clinical reports suggest that psyllium or other soluble fibers may lower lithium levels in the blood, reducing the effectiveness of this medication.

* In one clinical study, the fiber supplement guar gum reduced blood levels of penicillin.

Cellulose can clearly be a problem, especially when it’s ratio is too high as compared to the desiccated thyroid. So what can you do?

If you are using a compounded medication, strongly request powdered acidophiles, also spelled acidophilus, as your filler.  One gal states her compounding pharmacy uses powdered Ginger (but beware of too much Ginger if you have Mitral Valve Prolapse. It can cause palps if you take too much–my experience).  See what other fillers your compounder can offer.

Another possibility is Cellulase, an enzyme which helps the splitting and breakdown of cellulose, and which was proposed to me by Naturopathic student Stephanie Buist. Google “cellulase” and find supplements that contain it.  If it looks promising to you, I’ll be curious to read your experience with swallowing a cellulase supplement, then swallowing your problematic desiccated thyroid.

And leaning towards Erfa’s Thyroid can be a plus.

Have other ideas or comments about Cellulose in our desiccated thyroid? Use the COMMENT function below and let’s talk!

(This post garnered a lot of attention, up to FIFTY comments just a few hours after it went up. People are very interested in sharing their experiences in coping with the shortages! See below and add your own.)

This year will go down in history as shockingly miserable for enlightened thyroid patients on natural desiccated thyroid.

First came a reformulation in the most popular brand–Armour by Forest Labs. Patients worldwide in groups and forums reported a serious return of their hypothyroid symptoms on this product. A huge disappointment.

Second came the production shutdown of the two generic makers of desiccated thyroid: Time Caps Labs and Major Pharmaceuticals. It’s the first step in the FDA’s compliance plan to corral all grandfathered-in drugs (drugs already in existence when the the FDA was created in 1938) and make them each prove the efficacy and safety of their medication via very expensive clinical trials.  i.e. over 110 years of safe and effective use of desiccated thyroid is not enough for the FDA?? We are still waiting to see the outcome of that plan with RLC  and Forest Labs.–the two who were actually in existence before 1938.

Third came demand being greater than supply and shortages. Because of informative patient websites like Stop the Thyroid Madness,  Sheila’s TPA-UK, Lyn’s ThyroidUK, Stephanie’s Natural Thyroid Choices, some areas of about.com (and other good websites I don’t mean to miss here), plus many fine patient forums and groups,  patients found out why they had continuing symptoms on T4 thyroxine, and demand for natural desiccated thyroid grew exponentially.

STTM then created a list of options for all thyroid patients until the shortages resolved themselves, and also created CDT (Coalition for Desiccated Thyroid) where patients could discuss alternatives in a supportive and factual atmosphere.

And we’ve seen some interesting experiences and comments:

The new Armour: One grain tabs started to appear on some pharmacy shelves the past month.  Other pharmacies have still been waiting.  Many patients appear to have switched to other alternatives, though. One gal still on it feels she is finding success by adding T3 to the amount of new Armour she is on.  Time will tell if patients can ever find success with the newly formulated Armour, and most feel it’s a huge loss.

Naturethroid and Westhroid: Patients reporting on their switch to either of RLC Lab’s two identical products report doing well, having to raise it slightly or lower it slightly, or just not liking them at all. Others have had a hard time finding it on their pharmacy shelves, but have been seeing some appear in the last few weeks.

Erfa’s Thyroid from Canada: When it became clear that the FDA was allowing this excellent product to be shipped to patients, many switched and had their prescriptions faxed to a Canadian pharmacy. Prices at many of those pharmacy websites were doubled after prescriptions started to come in from the US. Most patient who stuck with it seem to love it, reporting you can do it sublingually, as well. A few haven’t been impressed, but were finding their former success by raising it.

Compounded desiccated thyroid: In spite of being a more expensive option, some patients found success with this. Others learned they preferred the filler to be Acidophiles.  If not the latter, Microcrystalline Cellulose was preferred over Methyl Cellulose–the latter which appeared to lessen the effectiveness of the compounded thyroid.

Synthetic T4 and Synthetic T3: some patients switched back to the synthetic combination, but many report that it hasn’t been as effective as desiccated thyroid was.

Other options: Patients moved to OTC products like Nutri-Meds, etc, which can be much weaker. Others sought desiccated thyroid from other countries and have found success.

So I’d like to hear from all of you.   Did you go back to synthetic T4?  What desiccated thyroid did you switch to? What worked and why? What didn’t work for you and why?  What product do you hope to switch to once you run out of your current meds?

Last May, a very interesting article appeared in the May 2009 issue of the Journal of Clinical Endocrinology and Metabolism, titled For Some, L-Thyroxine Replacement Might Not Be Enough: A Genetic Rationale and presented by Endocrinologists in Bristol in the UK. It’s accompanied with an editorial by Endocrinologists Brian W. Kim and Antonio C. Bianco.

This is the same article referred to by Endocrinologist Dr. Gary Pepper on the last Thyroid Patient Community Call on Talkshoe.

Basically, the article states that a genetic variation in the enzyme that converts T4 to T3, deiodinase D2 (also called Type 2 Deiodinase, or 5′-Deiodinase), may be responsible for why so many thyroid patients don’t do well on Synthroid, Levoxyl, levothyroxine, etc, and in turn, do so much better on natural desiccated thyroid like Naturethroid, Erfa’s Thyroid, or the combined synthetic T4 and synthetic T3 (Cytomel).

In other words, where some may have a strongly functioning deiodinase D2 enzyme which converts T4 to the active T3 well, others may have a modified deiodinase D2 enzyme, causing less optimal conversion.

In the Editorial, the two Endos Kim and Bianco explain the reality of “polymorphism”–a condition in nature in which changes or variations occur, and in one patient from another, a change in the DNA.  As related to conversion of T4 to T3,  some thyroid patients have a less effective deiodinase D2 enzyme in the conversion of T4 to T3.  Specifically, there is a common variant of the gene, threonine (Thr) 92 alanine (Ala), and it results in decreased D2 enzymatic activity.

The study proposes that this alteration from polymorphism occurs in 16% of those studied, and concludes that the majority don’t have this problem, and thus, “most do fine on T4-only medications”. But 16% do have this problem and need the combined therapy of T4 with T3.

Bristol was also mentioning this reality in 2004 here, even if they thought it was as low as 5%.

As Dr. Pepper hinted, this study could do wonders to open the eyes of Endocrinologists about the use of desiccated thyroid, or at the very least, about combined hypothyroid treatment with synthetic T3 added to synthetic T4.  And I’m glad for that when so many patients have found Endocrinologists to be narrow-mindedly stuck on Synthroid or other T4-only thyroxine products.

Of course, informed thyroid patients know this is only a baby step in the right direction, even if a good one! So we’ll rejoice for this study, and watch for more progress from the medical community and Endocrinology in general. For example, saying that “most do fine on T4″ simply because they have may a non-variation might be proven wrong as physicians take the time to really look at those “fine” patients, especially as they age and symptoms of an inferior treatment do pop up. And though the combination of synthetic T3 with synthetic T4 definitely gives better results, thyroid patients who then moved to desiccated thyroid with it’s T4, T3, T2, T1 and calcitonin report even better results and clinical presentation!  We’ve also learned that the TSH lab test absolutely sucks when it comes to diagnosis and treatment.  Read TSH Why It’s Useless, or see even more detail in Chapter Four of the STTM book, titled Thyroid Stimulating Hooey.

And finally: do thyroid patients really believe that problems with T4-only treatment is simply due to a genetic abnormality or variation? Maybe. But isn’t it funny that a healthy human thyroid does NOT depend solely on conversion, but also gives direct T3. hmmmmmm

P.S.  Patients also know that the use of the supplement Selenium helps with conversion, by the way, but has never stopped our first-hand knowledge that desiccated thyroid rocks!

I once cracked open an egg to find it had TWO shells.  And that oddity is equivalent to finding an Endocrinologist who supports the use of natural desiccated thyroid. 

Voila!! ~~ you can listen and talk to an Endo who does just that on this Thursday evening’s popular THYROID PATIENT COMMUNITY CALL on TalkShoe.

His name is Dr. Gary Pepper, Board Certified by the American Boards of Internal Medicine, and Endocrinology and Metabolism and editor-in-chief of metabolism.com.  Besides serving many years in distinguished leadership positions, he was selected as one of the top 100 physicians in New York City by New York Magazine and is also a featured expert with CNBC and ivillage on topics of diabetes and endocrinology. He states:  Almost daily I reread the words of Sir William Osler: “It’s often more important to know what sort of person this disease has than to know what disease the person has.”

i.e. this is one of a rare but growing breed of doctors who supports what we as thyroid patients already know–that desiccated thyroid is a five-star hypothyroid treatment and T4-only is about as effective as a doughnut diet for most. And lo and behold,  Dr. Pepper is an Endocrinologist! Of course, I can give no guarantees how he is as a doctor in his own office, but I do appreciate his understanding that T4-only treatment may not be the best way to treat hypo.

Join us this Thursday evening, 6 pm Pacific, 7 pm Mountain, 8 pm Central and 9 pm Eastern by clicking on the first link above titled Thyroid Patient Community Call.  When on that page, you’ll also see the exact day and time left before the call. You’ll be able to listen to the call right on your computer, or you can dial in and listen on your phone. There is also an option to talk one-on-one live with Dr. Pepper and Janie.

And remember: neither I or Dr. Pepper can offer personal medical advice or provide individual specific counseling. Those are between you and your personal physician.

***P.S.  PharmaTimes this month reported that this quarter’s sales of  Synthroid (levothyroxine) were up 3.7% to $134 million by Abbott Labs. Sad for most of those patients. If you know of someone who has been put on a T4 med, send them here: www.stopthethyroidmadness.com/t4-only-meds-dont-work or to the audio page here: www.stopthethyroidmadness.com/audio-shorts (third one down).

Sometimes there is a silver lining with the storm cloud of backordered US desiccated thyroid.

Erfa, the makers of the Canadian version of natural desiccated thyroid, simply called “Thyroid”, has recently announced that the FDA is not requiring the extensive FDA Form 1572 from US citizens and their doctors when they fill their prescriptions from Erfa directly. i.e. it’s now a lot easier to get your prescription filled directly from them.

http://www.erfa-sa.com/thyroid_usa.htm

And those who have started to use Erfa’s Thyroid report being quite pleased. A cherry on top is that Thyroid has that old sweet taste we used to all like with the old Armour, and it can be done sublingually as well! You can see the ingredients here.

Also, I am continuing to get emails from patients that both Armour and Naturethroid is starting to appear on pharmacy shelves, even if in small quantities.  I’m personally not too excited about Armour reappearing if Forest continues to make the reformulated version. Just too many patients reporting a return of hypo symptoms, even when they raise it, plus new symptoms of undertreatment and/or challenged adrenals thanks to the reformulated version. Sad. Oh how we will all miss the old Armour.

In the meantime, here are options for thyroid treatment we all have until we see a good return of desiccated thyroid, including Naturethroid and Westhroid. They are all far, far better than being on T4 alone like Synthroid, Levoxyl, levothyroxine, et al. You’ll also note compounded thyroid, which can be a good option, and you can read about on a recent blog post.  Australians happily use compounded in their own country. Any option you and your doctor choose may mean a readjustment by your body, by the way.
