Common Questions and Answers about Armour thyroid to levothyroxine conversion

Avatar f tn 100mcg of levothyroxine is about 60mg of armour -- you need to work with a doctor to make sure the conversion works out for you and that labs are appropriate.
640719 tn?1277140030 This means that each mcg of T3 is equal to 4 mcg of T4. Since Armour Thyroid contains 39 mcg of T4 and 9 mcg of T3, if you convert the T3 to equivalent T4 (multiply by 4), then 39 plus (9 times 4) equals only 75, not the 100 shown in the table. This suggests that the conversion of 100 mcg of T4 equals 60 mg of Armour is wrong. By the above calculation the 60 mg of Armour would only be equal to 75 mcg of T4.
Avatar m tn I think nobody should try this medication. My thyroid was attenuated by radioactive iodine. dr.gave me lavothyroxin then change to armour thyroid. Since then I have severe pain on my hips and lower back. He tested my TSH T3 AND T4 --normal then he tried bactireal tests--normal. ultimately he swithed me to cytomel and levthyroxin. My pain reduced to half but it is not going away. Now Dr. himself is puzzed . I have still have half pain and cramps.
314892 tn?1264623903 It looks like there is no direct conversion. It would be interesting to know. If someone has NO thyroid function, they would need the 100 nmol T4 and 5 nmol T3 per day. So I think that would be higher than a dose of 100 mcg/day. I suppose that is why getting the right dose is part guessing game.
Avatar n tn I would like to take armour hormone and not levothyroxine what is the dose I would take of armour if i'm taking 125 microgram of levothyroxine
178107 tn?1315947630 They think all you need is medicine with T4 only in it like Levothyroxine when I think a lot of people need both to get feeling back to normal and to have energy again and be able to lose weight. I also have seen that the levothyroxine has a list of side effects with it. The armour has no side effects as long as it is dosed correctly. I hope I was able to help. Good Luck.
Avatar f tn It occurs to me that they say Synthoid covers T4, but I am wondering if it does. People on Armour thyroid seem to have more energy. My sister was dx with Hashimotos about a year ago, they put her on Synthroid and she didn't like it. So he put her on Armour and she has lots of energy. I went to 4 Endocrinologist and NOT ONE would allow me to go on Armour! They say it's not pure, but people took freeze dried thyroid for 100 years and did fine on it.
Avatar f tn Hi I was wondering if anyone was switched to levothyroxine because of the shortage and had sucess with the transition. I was switched to levothyroxine 150 from being on Armour Thyroid 105 for about 2 years and had hyper symptoms and was was switched to levothyroxine 125 and still had hyper symptoms and labs. So the doctor decreased me to 100 and after 3 weeks was very tired, depressed, anxious and weak.
Avatar n tn If you live in the UK, how did you pursuade your GP to prescribe Armour for your thyroid problem? I have begged my doctor in the past to prescribe Armour for me but he said they do not use it in the UK. It's frustrating, because I feel that Levothyroxine does not suit me. I have been taking 100mcg for 15 years and it hasn't really eased my symptoms.
Avatar f tn I meant to add the conversion to 1 grain of Armour (60 mg) is 50 mcg. I've read different conversion dosages online but my endo prescribed 1 grain (60mg) a day for 50mcg of eutroxsig (generic version of Oroxine). I wasn't absorbing Armour so I switched back to Eutroxsig.
222011 tn?1265472048 I started having terrible heartburn/acid reflux problems. To get my T3 levels up the doctor changed my meds to Armour thyroid. At the same time she doubled my daily dose of Prilosec. In two days, the problems went away. I was curious as to which fixed those problems, so I went back to my once daily dose of Prilosec. Still had no problems. My conclusion was that the hypothyroidism was causing the acid reflux type problems, and the T3 gave me quick relief.
Avatar f tn Hello! I'm hoping someone can help me :) After being on a cytomel (10 mcg split throughout the day) plus armour 90 mcg or 1.5 grains my FT4 had tanked to the bottom of the range and even bit below while FT3 was above range. I had been on this combo for over two years never feeling great. In fact I had a very difficult time accepting the armour from the very beginning so we moved super slowly. I tended to get bloating and swelling and we titrated up slowly as a result.
Avatar f tn When the Armour shortage happened, I had to switch to Levothyroxine. I take 100 mcg/day to replace the 60mg of Armour. Since the switch in Dec. 09, I have gained nearly 30 lbs. and my heart is racing, fingers, face and abdomen swelling, anxious, losing hair, fatigued and no energy. I feel like I am dying. My Dr. ran more thyroid tests this week which came back as follows: TSH- 0.85 Range-0.35-4.94 UIU/ML Free T4- 1.37 Range-0.8-1.
Avatar f tn In addition to the problem with Armour mentioned by LM, the 60 mg Armour is not enough to substitute for 137 of Synthroid. According to readily available conversion charts, 80 mg would be the right amount. Personally, I would not even consider changing back to Synthroid at this time, and risking further hypo problems during the switch. I would take the additional Armour, or better yet, make a switch to Nature-throid, which is basically the equivalent of Armour, without its recent problems.
Avatar f tn s disease 10 years ago and have been on levothyroxine since. Does synthetic T4 convert to T3? I thought that T4 to T3 conversions occurred in the thyroid gland...so without one, where does this conversion take place? Desperately need advice as I've been miserable when my TSH is in the "normal range" and have resorted to self-treatment.
Avatar n tn Your problem is not the medication you are taking. Your problem is your thyroid. Changing medication is not going to change how your thyroid is acting. In order to have a discussion of what your condition is and what medication would suit you best, certain terms must be defined. You said your T4 and T3 results have never been really low, at worst just slightly below normal range. Slightly below normal range is actually terrible. You can be within normal ranges and still be low on hormones.
738890 tn?1232214279 I responded to synthetic levothyroxine initially and this came down to 5 but then relapsed and shot back to 12 with all accompanying symptoms of pre-diagnosis. They kept increasing the dose but to no avail. When taking synthetic levothyroxine, 15 minutes later, I feel sick and as if my body is trying to fight a poison, almost like fever or food poisoning, that's the closest I can approximate the feeling. So I stopped taking the synthetic levothyroxine.
Avatar f tn It is a synthetic conversion with your thyroid medication and your body may be pushing hard to convert the T4 into the T3 Have your considered trying Armour as a natural hormone replacement for thyroid? You may benefit greatly from the T1 T2 T3 and T4 already built in.
Avatar f tn After pratically begging my Doctor to switch from Levothyroxin to Armour, he finally wrote a script for it. I'm saying up front that I was taking 125mcg of Levothyroxin an i'm miserable. My dad takes Armour and he said he would never go back to synthethic. My dad has absoutely no Thyroid and is currently on 2 grains of Armour.
Avatar f tn But since T4 gets converted to T3, it’s not necessary to need to take both. Especially since, along with the thyroid, other organs of the body, like the liver, are contributing to that conversion. It only becomes necessary to need both when there is a conversion problem. Through blood work a dr can configure if the conversion is taking place. If there were a problem a dr would then prescribe an adjunct T3 med like the brand Cytomel. Rachel4: I agree.
Avatar f tn I have been thinking about switching from levothyroxine to a desiccated thyroid. Have been on 75 levothyroxine for about a year, and still having symptoms even though my Free T4 is ok, wondering if Free T3 could use a boost. I have Hashi's, if that makes any difference. I have heard that lots of people feel better after switching, but also that lots have had problems with the new Armour.
Avatar m tn Just being "in range" with vitamin B-12 and vitamin D are not good enough. I have to keep my B-12 at/near the top of its range in order to keep symptoms of deficiency at bay - that means my level has to be close to be around 1000-1100. Optimal vitamin D is 60-80...
1646889 tn?1301481228 Also meant to ask what were the dosages for the Levothyroxine and the Armour that you were switched to. The reason I ask is that doctors frequently use the wrong conversion factor of 1 grain of Armour for every 100 mcg of the T3 med. According to a couple of scientific studies and also the AACE/ATA Guidelines, they recommend that T3 is 3 times as potent as T4.
Avatar f tn I really expect that based on your success with the NutriThyroid, you may not be adequately converting the T4 to T3 and that you will need to go to a T4/T3 combo type of thyroid med such as Armour Thyroid, or Nature Throid. I suggest these rather than the OTC thyroid supplements, just because of the reputation for greater consistency and quality. You need to be sure that you are getting a consistent dose of your thyroid meds.
