640719 tn?1277140030 pdf If you look at the table you will note that 100 mcg of synthetic T4 is supposed to be the equivalent of one grain (60 mg) of Armour Thyroid. Then you look further and it shows 100 mcg of T4 to be equivalent to 25 mcg of T3. 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.
Avatar n tn you can google it conversion armour thyroid or look online there is a thread with some conversion charts on it.
727481 tn?1231203771 The conversion of T4 to an NDT med like Armour or Nature-Throid depends on an assumption of the activity of T3 to T4. Assumptions are that T3 is somewhere between 4 to 8 times as active as T4. Therefore, the conversion factors usually are one grain of NDT med is equivalent to somewhere between 75 and 100 mcg of T4. So your doctor gave you too much Armour. One grain would have been closer to your T4 dose.
Avatar f tn 1 grain armour (60mgs) = 100mcg levo, 1 1/2 grain armour (90mgs) = 150mcg levo, 2 grains armour (120mgs) = 200 mcg levo. These are approx, but you will probably end up on more armour than the conversion shows. Now.......you shouldn't start out too high of dosage either. That T3 will hit your system hard if you take too much to start. Usual start dosage is 60mgs. At top right hand area of this page you will find where it says health pages, go there, then find the armour information.
519035 tn?1348275773 According to the conversion chart, 1 grain (60 mg) is equal to 100 mcg snythroid, and 90 mg Armour is equal to 150 mcg levo. According to the manufacturer, there is 38 mcg of T4 and 9 mcg T3 in each grain. So if you work it out that way, 90 mg has only 57 mcg of T4 and 13.5 mcg T3. That said, this is a very old thread and the previous posters have not been active on the forum for a very long time, so it's unlikely that you will get a response from them.
Avatar m tn Well I've been on Armour Thyroid 1 grain split morning and early afternoon. Was on syntroid 125 mcg. My symptoms has seem to have gotten worse. Extreme nerve pain throughout my body with nerviness and shakes. Lack of appetite, bad headaches, tightness in the throat with a cough. This is the worst I've felt in along time and not sure what's causing the problem. Wasn't feeling good on the Synthroid either but these symptoms weren't as bad since I've switched to the Armour.
Avatar n tn How much does 90mg or 1 1/2 grain of Armour translate to how much of T3 or T4. The doctor decided to switch me to Armour for a month to see if my symptoms alleviate more. I been on on 75 synthroid and 15 cytomel ( split into twice a day) . Not sure if 1 1/2 grain is enough or too much.
3241062 tn?1346895870 I was wondering if anyone has a link to a conversion table for the Erfa Thyroid. I was on 75mcg of Synthroid and my gp started me on 30mg of Thyroid. I tried to tell him that it didn't match my T4 dosage but he wants to wait for the blood work,arrgh. I was feeling great on the 30mg for about a week-what a tease,lol. Now I'm back to where I was before.
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.
Avatar n tn Now in coverting to armour, should I take 1/2 grain or 3/4 grain? Also, how long will it take for levoxyl to be gone from my body and the armour to kick in by itself. I am sort of afraid to go through the hypo he// I've expereienced for 2 years now. Any ideas out there?
Avatar n tn In addition the Armour dosage of 45 mg is a significant reduction from the 88 mcg of Tirosint. Most doctors use the standard conversion tables showing that one grain of desiccated thyroid med like Armour is equivalent to 100 mcg of T4. That is incorrect. The ATA/AACE Guidelines for Hypothyroidism recognizes scientific studies that concluded that T3 was about 3 times as potent as T4. One grain of Armour (60) mg contains 39 mcg of T4 and 9 mcg of T3.
Avatar f tn It took 1 grain more of the Naturethroid (3 grains = 195mg) (1 grain at 4 hour intervals 3 times per day) to get the same results symptom wise and blood wise as the old good Armour (2 grains=120mg). ( 1 grain taken twice per day at 5 hour intervals). My daughter was born without a thyroid gland and weighs 120 lbs. 1 year ago at 100 lbs. she was on 100 mcg of Synthroid but was always too low on her t3 level on this medication (conversion issue).
Avatar n tn That's roughly an equivalent dose, "equivalent" meaning a recommended starting dose when switching to Armour. Armour can behave quite differently, so there's some experimentation involved at first. Most people split any meds with T3 in them into two half doses. Typically, half is taken first thing in the morning, and the other half around noon or early afternoon (not too late or sleep could be affected). You can also play with what balance works best for you, i.e.
Avatar f tn In fact, when people take Armour their RT3 will usually be lower and their FT3 much higher most of the day. So I just give such patients Armour thyroid until/unless Armour does not seem to be effective at strong doses and they seem to still overconvert T4 to RT3. Again, one has to then reconsider whether their body may be right and they cannot tolerate strong thyroid effects for some other reason.
Avatar n tn One doctor in this practice insisted in November that 1 grain of Armour was equivalent to this regime, even when I showed her the 38 t4/9 t3 per grain and that 2 1/2 grain was equivalent. 11 years ago I was on half of what I am on now, and was on 1 grain. Today, the other endo in this practice did not argue the correct conversion, directly. But she lost her mind over my suppressed TSH and refused to prescribe the current dosage of anything, synthetics or NDT.
Avatar m tn When it comes to conversion factors, it seems that the one used most often is one grain of Armour for each 100 mcg of T4. It all depends on what the assumption is for the effect of T3, compared to T4. There s another conversion factor I have seen that used 75 mcg of t4 for each grain of Armour. In either case, your 1 1/2 grains of Armour is slightly higher than just a straight substitution. So, it appears your doctor also increased your dosage.
Avatar m tn Have thought about adding back in the 50 mcg of Synthroid with the quarter grain of Armour. Has anyone tried this? I can also go back to Synthroid alone but there was so much hype on Armour I figured I should try it.
393685 tn?1425812522 Doing so much better. Labs are in 1 week. She is on 1 grain more of the Naturethroid then the Armour. (Conversion chart seems too modest). Problem is, now it is also hard to find. Armour "stepped in it "with the FDA and production has been halted. Who knows when and if it will be available in the future. Naturethroid and Westroid are both made by the same company and they are under a severe supply and demand crisis.They say they will be sending it to the pharmacies by mid November.
Avatar n tn I have taken taken thyroid medication for 25 years and have been on 1.75 grains of Armour thyroid for a number of years. Recently it's effectiveness for me declined. According to my Allergist and lab results (a high Antithyroglobulin Ab and my nutritionist, but negative Thyroid Peroxidase Ab; TSH 0.9), I could be producing antibodies to the natural thyroid so he suggested a switch to Synthroid and Cytomel. At the time I was also showing some signs of too much thyroid medication.
Avatar f tn I am at a loss as to why the doctor would switch you from Armour Thyroid to Synthroid. Using the appropriate conversion factor, your Armour dose was equivalent to 132 mcg of T4. Each grain of Armour contains 39 mcg of T4 and 9 mcg of T3. Multiply the 9 by 3 and add 39, which means that one grain of Armour is equal to 66 mcg of T4. So the 150 mcg of T4 is a slight increase, but may not do much at all if your body is not adequately converting T4 to T3.
Avatar f tn I have been on Levoxyl for several years since they quit making Armour thyroid. After several doasage changes I seem to level out. My throid blood tests always are on the low side. When I found out they were making Armour again I asked to be switched to it. This Dr. Prefers to go natural route as well. She switched me from 100mg levoxyl to 60 mg of Armour. Ifelt terrible after a few weeks so they raised it 1/4 grain. So I was due for 2 month blood work.
Avatar n tn 7-1.48) I started on Armour Thyroid at 1/4 grain -and increased to 1/2 grain(30mg.) During that time my lab results were: TSH 1.47 FT4 .89 TSH 1.08 FT4 .86 TSH .65 FT4 1.01 (this is when i felt best) but then after a few more months on 30mg TSH 1.07 Ft4 .9 and my dr increased me to 60mg Armour (but this is the new armour) my results: TSH .05 FT4 .86 and my hypo symptoms are back??? I have called my dr.
Avatar f tn Should I be on a lower dose of Armour? I found a conversion chart that says if I was on 100mcg of Synthroid, I should be on 1 grain or 65mg of Armour. If that is correct, than I am taking DOUBLE what I should be! I got freaked out and haven't taken my Armour for 2 days & now waiting to hear back from my Dr about the dose. I would appreciate any input anyone can give me on the dosage of Armour. Thank you!
1019013 tn?1252002096 Save yourself possible hypo. grief : I recommend Nature-thyroid NOT Armour if you choose to use a desicated "natural" hormone. New Armour formula failed us recently. Switched 1 month ago to Naturthroid. Doing much better symptomatically. Waiting for lab results 9/20. Was on Synthroid (t4 only) for many years. Not converting enough to t3 (ACTIVE HORMONE). Always check your free t3 levels! If too low, but t4 is high normal, then t3 will be needed along with the t4.
