Synthroid Versus Levothyroxin

After reading the post about the name brand synthroid not being positive that it is gluten free, I spoke to my doctor about trying the generic version. Of course, I got the generic that wasn't listed on glutenfreedrugs.com. I did e-mail Mylan and got a phone call back saying that they don't put gluten in any of their medications. They said that the use corn and rice for the fillers. My doctor did tell me when some of his patients changed to the generic they needed to take an extra pill a week. I do absorb medication in strange ways, so we will see.

I too am on Synthroid. Not everyone can take the generic Levothyroxine and have to take name brand. The name brand Synthroid from Abbott laboratories is gluten free. Hope this helps.

If you look on glutenfreedrugs.com, Abbott can no longer guarantee that all strengths of synthroid are gluten free. I did call them and was told they survey their suppliers and the suppliers say their isn't gluten, yet Abbott will not say yes there is gluten or no there is not. All I know since the last time I filled my synthroid, I feel like I am getting glutened from somewhere. At first I thought that it was the holidays, but it is still going on. Others on this site have called Abbott also. I know that Abbott seems to be doing the CYA, but I just feel I need to be told yes or no, not figure it out for yourself.

Thanks for the info.

Did I miss something? You have one company (Abbott) that says their suppliers say there is no gluten but they won't make a guarantee. You have another company (Mylan) that says they don't put gluten in their generic product.

We all have to make our choices on these but I don't see either of these are any more likely or less likely to be an issue. If anything, the fact that Abbott routinely surveys their suppliers instead of just saying "WE don't add any" makes me slightly more trusting of them.

I take the generic Synthriod, Mylan's Levothyroxin, and was started on samples of the name brand, I've noticed no difference between the two, personally. I know everyone's different, and some have issues, but as long as you're feeling well, stay with the same dose. Likewise, if you start slowing down again, have your PCP up your dose, or draw bloods for comparison. FYI- I'm not the celiac, DH is, so if the Mylan's brand is glutened, I wouldn't know.

I take Levothyroxine. Not sure what brand or whatever. But I've never had a problem with it.

I had my thyroid removed in February 2009, and I have just had a personal experience with using Synthroid. After taking the 112 mcg dosage for 2 weeks, I started having progressively worsening intestinal cramping. At first, I thought it was a virus, but since it lasted much longer and I had no other virus-type symptoms, I narrowed the problem down to being the last thing I changed in my diet---that is, when I began taking Synthroid PINK-colored 112 tablets! My husband and I did some research and found out that these 112 mcg tablets contain Red Dye No. 27 Lake, which is not gluten-free. This is what the manufacturer uses to color their tablets PINK. Although we have no chemical proof of our findings, the intestinal cramping stopped immediately when I stopped using the Synthroid brand. I switched to using Levoxyl's 112 mcg pill, which Monarch industries guarantees IS gluten-free. My husband spoke directly to an Abbott representative, and they STILL WILL NOT guarantee that their Synthroid brand of 112 mcg tablets is gluten-free. A couple of days later, an Abbott representative called my husband back and asked if he would be willing to give them details of my adverse reaction to using their Synthroid product so that they would have an official report for the company. Perhaps this is a requirement of the FDA whenever someone has a reaction. My advice for any Celiac with a very sensitive and reactive colon is to NOT use Synthroid brand of PINK 112 mcg tablets. (Note: Other dosages they manufacturer do not contain any red dye so they might be okay.) Hope this information helps others.

Good note about the dye :(

I take the yellow 100mcg Synthroid tablets. I started with generic levothyroxine, but I finally saw an endocrinologist and he wanted me to switch to the name brand (to ensure a more accurate dose from batch to batch). Personally, I haven't noticed much of a difference... I wouldn't hesitate to go back on the generic if I couldn't afford the name brand.

I have taken both. I have taken the generic far more and longer than the brand name. I don't have any problems with it either. I only have to pay $10.00 for a three month supply if I get the generic. I have not tried to ask for the brand name one. I suspect the ins. would not pay as well. I had an endocrinologist once tell me the same thing about switching to synthroid to ensure more consistency between batches because most of his patients were on that. I was on the generic at the time and he said well then it should not matter as long as you are taking the same brand of generic the dose should be consistent from batch to batch.

Wow.

I take Levoxyl 137 mcg - and I still have my thyroid!

I spent several years asking to get my thyroid checked because I was rashy, exhausted and gaining weight regardless. NOBODY would run any kind of test - they (several doctors, OB/GYN, GP) just told me I had "elbow disease" - which is a euphemism for overeating. If anything, I've always eaten about half what other people eat and most people comment on the small amounts I eat. So, I finally went to one of those "mall health fairs" and spent $35.00 to get a blood test, which showed, lo and behold! My TSH was roughly 3.5. I then found an endo, who immediately said, basically, "Of course you need to be on meds, and we need to get a sonogram," etc., which made me feel better - until the jerk decided the other reason why I felt bad was because I was "depressed" and gave me samples and a 'scrip for Effexor. Which I refused to take until I did some research and then I REALLY refused to take it. C'mon - something that usually requires liquid Prozac to wean you off of it? NO THANKS!

BUT, I've always been on Mylan - when the company that makes it is in West Virginia, and you LIVE in West Virginia, that's what you get :)

I've been gluten free for over a year and suddenly I have been so ill for almost two weeks. I know I am not eating anything with gluten. The only thing I have done is started a new thyroid prescription (levothyroxine/synthroid). Upon closer inspection I realize that I am taking Abbott's name brand pills now rather than my usual generic. I am stopping the new script immediately and ordering more medication...back to the generic!

      @Jane02, I hear you about the kale and collard greens.  I don't do dairy and must eat green leafies, too, to get sufficient calcium.  I must be very careful because some calcium supplements are made from ground up crustacean shells.  When I was deficient in Vitamin D, I took high doses of Vitamin D to correct the deficiency quickly.  This is safe and nontoxic.  Vitamin D level should be above 70 nmol/L.  Lifeguards and indigenous Pacific Islanders typically have levels between 80-100 nmol/L.   Levels lower than this are based on amount needed to prevent disease like rickets and osteomalacia. We need more thiamine when we're physically ill, emotionally and mentally stressed, and if we exercise like an athlete or laborer.  We need more thiamine if we eat a diet high in simple carbohydrates.  For every 500 kcal of carbohydrates, we need 500-1000 mg more of thiamine to process the carbs into energy.  If there's insufficient thiamine the carbs get stored as fat.  Again, recommended levels set for thiamine are based on minimum amounts needed to prevent disease.  This is often not adequate for optimum health, nor sufficient for people with absorption problems such as Celiac disease.  Gluten free processed foods are not enriched with vitamins like their gluten containing counterparts.  Adding a B Complex and additional thiamine improves health for Celiacs.  Thiamine is safe and nontoxic even in high doses.  Thiamine helps the mitochondria in cells to function.  Thiamine interacts with each of the other B vitamins.  They are all water soluble and easily excreted if not needed. Interesting Reading: Clinical trial: B vitamins improve health in patients with coeliac disease living on a gluten-free diet https://pubmed.ncbi.nlm.nih.gov/19154566/ Safety and effectiveness of vitamin D mega-dose: A systematic review https://pubmed.ncbi.nlm.nih.gov/34857184/ High dose dietary vitamin D allocates surplus calories to muscle and growth instead of fat via modulation of myostatin and leptin signaling https://pubmed.ncbi.nlm.nih.gov/38766160/ Safety of High-Dose Vitamin D Supplementation: Secondary Analysis of a Randomized Controlled Trial https://pubmed.ncbi.nlm.nih.gov/31746327/ Vitamins and Celiac Disease: Beyond Vitamin D https://pmc.ncbi.nlm.nih.gov/articles/PMC11857425/ Investigating the therapeutic potential of tryptophan and vitamin A in modulating immune responses in celiac disease: an experimental study https://pubmed.ncbi.nlm.nih.gov/40178602/ Investigating the Impact of Vitamin A and Amino Acids on Immune Responses in Celiac Disease Patients https://pmc.ncbi.nlm.nih.gov/articles/PMC10814138/

      Thank you so much @knitty kitty for this insightful information! I would have never considered fractionated coconut oil to be a potential source of GI upset. I will consider all the info you shared. Very interesting about the Thiamine deficiency.  I've tracked daily averages of my intake in a nutrition software. The only nutrient I can't consistently meet from my diet is vitamin D. Calcium is a hit and miss as I rely on vegetables, dark leafy greens as a major source, for my calcium intake. I'm able to meet it when I either eat or juice a bundle of kale or collard greens daily haha. My thiamine intake is roughly 120% of my needs, although I do recognize that I may not be absorbing all of these nutrients consistently with intermittent unintentional exposures to gluten.  My vitamin A intake is roughly 900% (~6400 mcg/d) of my needs as I eat a lot of sweet potato, although since it's plant-derived vitamin A (beta-carotene) apparently it's not likely to cause toxicity.  Thanks again!

      Hello, @Jane02,  I take Naturewise D 3.  It contains olive oil.   Some Vitamin D supplements, like D Drops, are made with fractionated coconut oil which can cause digestive upsets.  Fractionated coconut oil is not the same as coconut oil used for cooking.  Fractionated coconut oil has been treated for longer shelf life, so it won't go bad in the jar, and thus may be irritating to the digestive system. I avoid supplements made with soy because many people with Celiac Disease also react to soy.  Mixed tocopherols, an ingredient in Thornes Vitamin D, may be sourced from soy oil.  Kirkland's has soy on its ingredient list. I avoid things that might contain or be exposed to crustaceans, like Metagenics says on its label.  I have a crustacean/shellfish/fish allergy.  I like Life Extension Bioactive Complete B Complex.  I take additional Thiamine B 1 in the form Benfotiamine which helps the intestines heal, Life Extension MegaBenfotiamine. Thiamine is needed to activate Vitamin D.   Low thiamine can make one feel like they are getting glutened after a meal containing lots of simple carbohydrates like white rice, or processed gluten free foods like cookies and pasta.   It's rare to have a single vitamin deficiency.  The water soluble B Complex vitamins should be supplemented together with additional Thiamine in the form Benfotiamine and Thiamine TTFD (tetrahydrofurfuryl disulfide) to correct subclinical deficiencies that don't show up on blood tests.  These are subclinical deficiencies within organs and tissues.  Blood is a transportation system.  The body will deplete tissues and organs in order to keep a supply of thiamine in the bloodstream going to the brain and heart.   If you're low in Vitamin D, you may well be low in other fat soluble vitamins like Vitamin A and Vitamin K. Have you seen a dietician?

      I do not know this, but since they are labelled gluten-free, and are not really a product that could easily be contaminated when making them (there would be not flour in the air of such a facility, for example), I don't really see contamination as something to be concerned about for this type of product.
