Thyroid Overview

The thyroid, or thyroid gland, is an endocrine gland in vertebrates. In humans it is in the neck and consists of two connected lobes. The lower two thirds of the lobes are connected by a thin band of tissue called the thyroid isthmus. The thyroid is located at the front of the neck, below the Adam's apple. Microscopically, the functional unit of the thyroid gland is the spherical thyroid follicle, lined with follicular cells (thyrocytes), and occasional parafollicular cells that surround a lu...

Tirosint and weight gain

I switched from Synthroid to Tirosint. I have gained 8 lbs, constipated, hair loss and HBP. Can anyone explain this?

Stopping Levothyroxine

I have been taking Levothyroxine .88mg for the past two years. I just left town on a three week vacation and realized I left this prescription at home. Should I be concerned? ## If you suddenly stop taking Levothyroxine, your body can go through withdrawal. "Levothyroxine withdrawal may cause hypothyroidism, or underactive thyroid. Hypothyroidism causes weight gain, fatigue, depression and sensitivity to cold because your body does not have enough thyroid hormone so your body processes slow down. Patients with thyroid cancer may suffer acute hypothyroidism because of levothyroxine withdrawal." Referenced from: Since you've been taking this medication for so long, I would consider contacting your doctor about this if you have be...

Is Amneal Levothyroxine 100 mcg Gluten-free?

Is the Amneal brand of Levothyroxine gluten free? I can't seem to find definitive wording that it is. ## Are you referring to the yellow pills inscribed JSP 516? If so, the inactive ingredients listed for Amneal Levothyroxine 100 mcg (NDC 69238-1834) are: - Silicon Dioxide - Lactose, Unspecified Form - Magnesium Stearate - Cellulose, Microcrystalline - Starch, Corn - Acacia - Sodium Starch Glycolate Type a Potato - D&C Yellow No. 10 - FD&C Yellow No. 6 - Aluminum Oxide Please correct me if I'm wrong, but those don't appear to be gluten-based ingredients. The question would then be whether there is a risk of cross-contamination on the equipment they use in manufacturing the pills. Ref: DailyMed ## Yes, that is the tablet I'm referring to. And your answer is helpf...

Thyroid hormone, T3 (liothyronine) without Talc

Does anybody know if there is a liothyronine without Talc in it as an inactive ingredient? I have allergic reactions or side effects of Talc as a filler in medicine, causing fever, dehydration, choking (breathing problem). So I take medicine without it. Synthroid has it in it so I take generic Levo in the U.S. (it seems that all generic does not contain talc as I tried my manufacturer's levo) Cytome (T3) has Talc in it too so I asked my doctor to prescribe generic T3, but unfortunately my generic lionthyronine from Rite Aid has talc in it. ## The best thing to do is to inform your pharmacist of your allergy, to ensure that it's noted in your file, and they can avoid providing you with medications that contain it, in the future. While some companies do have their inactive ingredi...

Synthroid and Levothyroxine tablets taste just like SUGAR!

I took levothyroxine tablets for over 2 years then stopped. Why did I stop? Because they did absolutely nothing for me -- I kept gaining weight and continued to have all the same symptoms I had prior to taking them. BUT, the most important reason I stopped taking them was because I chewed a tablet (out of mere curiosity) and it tasted just like SUGAR! Oh so sweet. why do they make a tablet taste like sugar when the instructions are to swallow it whole and NOT suck or chew it? (because they don't want you to discover it tastes like sugar). I believe that Levothyroxine and Synthroid (& most likely all other medication like these) are just SUGAR and that we are all being greatly DECEIVED. I recently went to my GP and she urged me to go back on Levothyroxine for my underac...

Levothyroxine Menopause/Weight Gain?

I had two radio-iodine treatments to kill my thyroid, which was extremely over active, approx. 6 yrs ago. I have been on Levthyroxine for about 5-1/2 yrs now and do not experience the things a lot of you are. No hair loss (I have very thick hair), no dizziness, panic attacks, etc. HOWEVER I am going through menopause now also (at 53) and can't lose weight, the insomnia is rather bad along with the night sweats. Could it be from menopause? I check my levels every 6 months with my Dr. as I recommend everyone to do. I'm going to ask him about Synthroid next time I'm in. He will not prescribe a higher dose than what I have now (112 mg) as he doesn't want the Levothyroxine to affect my joints/bones in the long run and my TSH levels he keeps on the higher side already. The wei...

How long does Tirosint take to work?

Been on Synthroid for years (1990's) never been able to get any good results, felt like I was being poisoned every time I took it, my symptoms were horrible. Recently got in to see endocrinologist that prescribed tirosint along with cytomel. 8th day now and a lot of the symptoms I was having on Synthroid are gone, but was wondering how long before I could see results from tirosint. Would love some feedback ## There is really no way to say for sure, generally it takes about 4 to 5 weeks for a medication to reach its full level of efficacy in the body, but it can vary, since we are all different. Ref: Tirosint Information Cytomel Information The FDA lists the side effect you may experience as possibly including: nausea, dizziness, appetite changes, heat sensitivity, excessive sweating...

Synthroid and yellow tongue

My tongue is always yellow. It's not my oral hygiene. I have been on Synthroid for years. Could it be the cause? ## Hello, Donia! How are you? Is the only medication you take regularly? I didn't find anything specifically listed about Synthroid/Levothyroxine causing this, but there are so many things that can, including foods, beverages, and oral care items that it's hard to be sure. Ref: Medline Plus Synthroid Is there anything that you eat, or drink every day that might be causing it? Have you spoken to your doctor, or dentist about it? ## I have same problem, I want to stop my medicine, it has been 5 days I am not taking, instead I am taking 2 drops of Lugol’s Idoine in the mornings.

Cytomel out of stock 2022

Anyone know something about why Pfizer has made this unavailable to pharmacies? ## I, too, would love to know if any pharmacy is stocking Cytomel.

Changing Levothyroxine manufacturers every 2 years

I've been taking synthroid/levothyroxine for over 35 years. Since Medicare Part D I have changed pharmacy 3 times due to costs. Although my TSH reads normal I have more hypo symptoms. Most worrisome is a change in LDL. I always had perfect heart ratio. Nails and skin are very brittle/dry, some hair loss, breast enlargement with weight gain (walk 3 miles/day), and GERD. All related to age? These issues are increasing over time with keeping same dose of Levothyroxine. Any suggestions if I should attempt taking Synthroid and stay with one manufacturer? But then I would be paying out of pocket or get a more expensive RX plan? Or take my chances on new plan thyroid med called EUthyrox? Anyone's experience with this issue would be appreciated. ## Has your doctor done any testing, outs...
