What's the deal with Synthroid? I'm on .025 mg and have just read it may contain gluten? Does it contain dairy? I don't tolerate dairy or gluten and am concerned. Are any thyroid meds gluten and dairy free?

Synthetic T4 is identical to that produced in the human thyroid gland. Levothyroxine (T4) sodium has an empirical formula of C15H10I4N NaO4• H2O, molecular weight of 798.86 g/mol (anhydrous), and structural formula as shown:

Inactive Ingredients

Acacia, confectioner's sugar (contains corn starch), lactose monohydrate, magnesium stearate, povidone, and talc. The following are the color additives by tablet strength:

*Note – FD&C Yellow No. 6 is orange in color.

My pharmacists will not state my synthroid is gluten free because of possible cross contamination issues.

I use name brand synthroid with no problems ,I can not use the generic alternative

, but I am not super sensitive to gluten. I am how ever super, SUPER sensitive to soy ( but that is another topic)

Another thing to consider are you having issues with corn??

Can hashimoto's resolve if these intolerances are removed?

. I am also going to eliminate coffee, as I read it has a similar structure in protein to gluten.

Coffee will not gluten you. If you are newly diagnosed it may be too much for your stomach but that is not a gluten issue. Coffee is safe.

Update on rash/synthroid:

I took out coffee, and most of the gas/bloating disappeared, but it reappeared heavily when I had Claritin D. Today, the rash on the back of my legs flared for the third time, with no suspicious foods/allergy meds present. I also got the same rash on my wrists, forearm and upper thighs in addition to the back of my knees. It burned so badly, I called the endocrinologist to see if it was a reaction to synthroid apart from gluten issues.

He said, "Oh, you're on synthroid? That has gluten in it. We always do Tirosint for our gluten patients." Abbott told me they don't test for gluten, but the people who make the ingredients say no gluten ingredients are used, but they can't say it's gluten-free.Anyway, back to the endo. You'd think they would have thought of this before. Anyway, they will give me Tirosint starting Weds. morning, so one more day of synthroid. But I'm heading to the dermatologist Weds. a.m. to have a biopsy done of the rash to see if I have a true celiac issue- DH.

I'm hoping this new med resolves the indigestion. I'm tired of it and working so hard to be gluten-free 100%!!!

Thanks to all who helped with this.

Synthorid is gluten free. You should consider it a myth that any thyroid medication contains gluten until proven otherwise. About 80% of my endo's patients are celiac or gluten sensitive and he's never once mentioned that Synthorid contains gluten and has prescribed it to me when Armour isn't available.

Many pharmacutial companies will not guarantee a medication is gluten free but Synthroid does not contain ANY gluten ingredients. There are many, many people on this board taking Synthoid and generic equivilents without issues. Many medications have additives (like blueanj mentioned here) and I am sensitive to dyes - that could be your issue or it could be the corn starch as you said.

If you continue to have issues you can try a natural version like Armour or have it made for you at a compounding pharmacy (I've used this one in the past when there was an Armour shortage - Open Original Shared Link)

BTW - This site is invaluable when researching drugs. Bookmark it because it's hard to find: Open Original Shared Link You can find the prescribing sheets and active and inactive ingredients for the name brand and generic equivilent (even by manufacturer) - click on theraputic equivilent on the page for the name brand to see a list of all of the manufacturers who make generics.

Good luck! Things will get better for you. It's always difficult in the beginning to figure out exactly what is causing things and as you heal things will bother you less. :)

      Help I’m cross contaminating myself,

      By knitty kitty · Posted

      I followed the Autoimmune Protocol Diet which is really strict for a while, but later other foods can be added back into your diet.  Following the AIP diet strictly allows you digestive system to heal and the inflammation to calm down.  Sort of like feeding a sick baby easy to digest food instead of spicy pizza.   It's important to get the inflammation down because chronic inflammation leads to other health problems.  Histamine is released as part of the autoimmune response to gluten.  High histamine levels make you feel bad and can cause breathing problems (worsening asthma), cardiovascular problems (tachycardia), and other autoimmune diseases (Hashimoto's thyroiditis, diabetes) and even mental health problems. Following the low histamine version of the AIP diet allows the body to clear the histamine from our bodies.  Some foods are high in histamine.  Avoiding these makes it easier for our bodies to clear the histamine released after a gluten exposure.   Vitamin D helps regulate the immune system and calm it down.  Vitamin D is frequently low in Celiacs.  The B Complex vitamins and Vitamin C are needed to clear histamine.   Supplementing with essential vitamins and minerals boosts your intestines' ability to absorb them while healing.   Keep in mind that gluten-free facsimile foods, like gluten-free bread, are not enriched with added vitamins like their gluten containing counterparts are.   They are empty calories, no nutritional value, which use up your B vitamins in order to turn the calories into fuel for the body to function.   Talk to your doctor or nutritionist about supplementing while healing.  Take a good B Complex and extra Thiamine in the form Benfotiamine (shown to promote gut health).  Most B Complex vitamins contain thiamine mononitrate which the body cannot utilize.  Meats and liver are good sources of B vitamins.   Dr. Sarah Ballantyne wrote the book, the Paleo Approach.  She's a Celiac herself.  Her book explains a lot.   I'm so glad you're feeling better and finding your balance!

      So I should not eat my gluten free bread?  I will try the vitamins.  Thank you all so very much for your ideas and understanding.  I'm feeling better today and have gathered back my composure!

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      By knitty kitty · Posted

      Some people prefer eating gluten before bed, then sleeping through the worst symptoms at night.  You might want to try that and see if that makes any difference.   Several slices of toast for breakfast sounds okay.  Just try to work up to the Ten grams of gluten.  Cookies might only have a half of a gram of gluten.  The weight of the whole cookie is not the same as the amount of gluten in it.  So do try to eat bread things with big bubbles, like cinnamon rolls.   Yeah, I'm familiar with the "death warmed over" feeling.  I hope you get the genetic test results quickly.  I despise how we have to make ourselves sick to get a diagnosis.  Hang in there, sweetie, the tribe is supporting you.

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      By Xravith · Posted

      @knitty kitty  Thank you very much for the advice. I did the exam this morning, my doctor actually suggested me to take something called "Celiac duo test" in which I first do the genetic test and if it's positive, then I'll have to do the antigen blood test. I have to attend 1 month until my results are ready, so I have some weeks to increase the amount of gluten I eat daily. It will be hard because my health is not the best right now, but I also did a blood test to cheek my nutritional deficiencies. The results will arrive on Tuesday, so I can ask my doctor what should I do to control my symptoms and blood levels during this month. For now I'm resting and paying attention to what I eat— at least I don’t look like a vampire who just woke up, like I did yesterday. I'm still scared because is the first time I've felt this sick, but this is the right moment to turn things around for the better.  I realized that if I eat gluten at lunch I cannot finish the day properly, I become severely tired and sometimes my stomach hurts a lot - let's not talk about the bloating that starts later. Do you think is it ok to eat gluten just in the morning, like some cookies and slices of bread for breakfast?
