Cytomel equivalent to synthroid

Common Questions and Answers about Cytomel equivalent to synthroid

cytomel

Avatar n tn Personally I would not make the switch now. I think you should be re-tested when you have been on the Synthroid /Cytomel long enough to stabilize and reach full levels in your blood. Since T3 reacts very fast, but the T4 is slower, I need to know how when you started on this most recent dosage of Synthroid. At any rate, whenever it has been long enough, you should go back for testing for free T3 and free T4, along with TSH, before even considering the switch.
Avatar n tn You have to have the proper ratio of both or you will still remain and feel ill. So, you need T4 and T3 meds both. I switched from armour to synthroid and cytomel. And then had to do teh labs every 6 weeks to make sure I was on correct dosage. Cytomel is very potent. I was on 120mgs of armour. I am now up to 100 mcg synthroid and 15 mcg cytomel.
Avatar f tn Cytomel 10mcg is the equivalent of adding 40mcg of synthroid. The addition of thyroid hormone usually decreases TSH. Metformin can be taken with thyroid meds, but would take the thyroid meds at least 30 minutes before a meal, and metformin after a meal.
Avatar m tn If you reduce the T4 med to say 110, then 5 mcg of T3 is equivalent to 15 mcg of T3, so the total effect would be equivalent to 125 mcg of T4 again. So that is why I said you might need to add another 5 mcg of T3, which would give you 110 plus (3 times 10 mcg of T3) which is equivalent to 140 mcg of T4. So that would give you an increase that you seemed to need, since you were having symptoms at 125.
Avatar n tn I, personally, would give it a couple more weeks, at least, before adding any more Cytomel (stay at 12.5 mcg total) It is fast-acting, but even if it does bring your FT3 up rather quickly, you are going to continue having symptoms for a while until your body heals. Are you still taking 75 mcg Synthroid, split. or are you just taking 37.5, altogether?
535882 tn?1396576685 Since you are on Synthroid now, you may want to suggest adding .5 or .10 mcgs of Cytomel first - just to see.
734073 tn?1278896325 That's a LOT of Cytomel. 50 mcg of Cytomel is roughly equivalent to 200 mcg Synthroid. You're right, the reduction in Synthroid is not enough to compensate for the Cytomel addition. I'd certainly start out lower and split the dose. Most people we hear from taking it split their dose...of course there are always individual differences and you have to experiment with what works best for you. A one-to-three ratio of T3 to T4 is also skewed.
Avatar f tn 5mcg (150 mcg equivalent of Synthroid) for a month and then taken off of it to prepare for RAI ablation. After my RAI I was still start on 137 mcg Synthroid. On that dose of Cytomel I was pretty miserable just about every day...I had headaches, anxiety, etc. Hopefully, this starting dose of Synthroid will make me feel ok. I heard it can take up to a year or more (YIKES!) to find the correct dosage. So I don't have any experience with Armour, but I did find this website: http://www.
Avatar n tn He reluctantly agreed to give it a try. He has prescribed lowering my Synthroid to 100 and adding Cytomel 5 b.i.d. for a total dose of 10. I think that seems a little high? My labs are: TSH 1.68. FT4 1.06. Total T4 9.7. Total T3 0.88. Total T3 uptake 37%. I do not know if Cytomel will help or not, but I am willing to try it versus living with the symptoms forever and ever....If not, I guess it is a life of "happy" Synthroid and symptoms!
Avatar f tn T3 is about three times as potent as T4, so your current dose of 88 mcg of Synthroid and 20 mcg of T3 is equivalent to 148 mcg of T4 (88 + 3 times 20 = 148). So with that dose increase you are feeling better; however, it increased your T4 from about 68 to 88, which is the wrong direction when having high RT3. To switch to NatureThroid plus T3, I think the best dose would be 1 1/2 grains of NatureThroid plus 10 mcg of T3. This would give you 58.
Avatar n tn I am on thyrolar-3 and an additional 12.5mcg of cytomel. this is the equivalent of 350mcg of synthroid. when I was on the equivalent of 300mcg synthroid (take thyrolar 3 whihch is 150mcg T$ and 37,5mcgT3) my TSH was still 4.0. however my free T4 was normal, I think there is something else at play here....wilsons syndrome (reverse T3 production) or an adrenal problem. thoughts?
Avatar n tn Hi, I had thyroid cancer 6 years ago and got my thyroid removed and did a session of RAI. I have been on Synthroid ever since and added cytomel about two years. Due to the cancer they always keep my TSH around .5 or lower. I was still suffering with some symptoms and decided to try out the Amour Thyroid. My doctor switched me about 7 weeks ago to 60 mg once a day. I just got my blood work back and my TSH jumped from .5 to 26.57.
Avatar f tn The amount of cytomel is fairly high (total of 40mcg/day -- roughly the equivalent of 160mcg of synthroid, which in addition to the 125mcg 1/2 tab is 222.5mcg of T4/day -- more than what most people need). Going through menopause may be more of the problem than a thyroid imbalance but change in estrogen status may alter thyroid requirements. Would consider consultation with an endocrinologist to sort out the best options.
Avatar m tn Just a couple of thoughts. If, as I suspect, you dropped the Synthroid/Cytomel and switched to Armour at the same time, then you basically increased your T3 dosage, which probably gave you a boost for a while until your T4 levels normalize to the new amount of T4 from the Armour. Once this takes place over 4-5 weeks, then I think you might feel like you are dropping back into your prior level of symptoms.
Avatar f tn The 88 mcg of Synthroid plus 15 mcg of Cytomel is equivalent to 133 ,cg pf T4. Since T3 is 3 times as potent as T4 it is calculated as follows: 88 plus (3 times 15) equals 133. Since a grain of Armour contains 39 mcg of T4 and 9 mcg of T3, that is equal to 66 mcg of T4. So 2 grains of Armour is equivalent to only 132 mcg of T4. Overall you went from 88+ 15 to 78 plus 18, so no noticeable effect would be expected from the change.
Avatar n tn This week I was able to see a endocrinologist and he repeated my labs. Now my TSH is 1.9, he decided to change my synthroid to 100 much and added Cytomel 5mcg twice a day. I’m not familiar with Cytomel, will the addition of this medicine compensate reducing my synthroid? Will it help with my Simptoms? Thank you!
793305 tn?1493925518 Considering how potent Cytomel is compared to Synthroid (4X), your endo is really adjusting your dose in wild swings. 25 mcg of Cytomel is roughly equivalent to 100 mcg of Synthroid. So, she's putting you on 1.5 times the amount of thyroid meds for 10 days, then taking you off. And that's supposed to ease drug transitions? That's the first time I've ever heard that rationale...makes absolutely no sense to me...sounds like a prescription for misery.
Avatar n tn t answer your specific question about the conversion to synthroid/cytomel, but I have to ask - about a generic for cytomel? According to both my endo and pharmacist, there is no generic for cytomel......
Avatar f tn s fairly rare for somone to be on Cytomel only. Usually a small dose of Cytomel is added to the Synthroid, which may have to be reduced to accomodate the Cytomel. Cytomel (T3) is very fast-acting, so it has to be taken several times throughout the day if taken by itself. This leads to intra-day ups and downs in hormone levels. Do you have the results of your latest lab tests (FT3, FT4 and TSH) and their reference ranges?
1019013 tn?1252002096 It is possible to do T4/T3 comination with levothyroxine (synthroid) and cytomel -- this may help. The 1 grain of Nature-thyroid is the equivalent of 100mcg roughly of synthroid -- that's why your TSH went up. In this case we would consider (assuming 150mcg is keeping TSH in the 0.5-2.5 target range) using 112mcg of synthroid and 5mcg twice daily of cytomel. About 15-20% of patients respond to this (less fatigue and brain fog).
Avatar n tn Thanks again, g. I am looking into a move out of here, and heading north. I have had enough of this heat, as it gets worse for me, each year. lol. I have only been on the 88 mcg 1 1/2 weeks from the 112 reduction. I think you are correct, about the synthroid. I may skip a day in this dose and In a few days, I will add the additional 2.5 to total the full 5 mg of Cytomel. I am a long way from the 10 mg he originally ordered.
Avatar n tn Then backing with blood work and listening to the patient the doctor could prescribe adding a T3 Cytomel to your Synthroid to see if you feel better. But usually not stop Synthroid entirely. I found my doctor frowned on Cytomel for some reason when I was still on Synthroid so he made the decision along with my inquiry to try a T4/T3 combo medication Armour. That has definately made a huge difference for me in relieving my symptoms of hypothyroidsim. HUGE!!
1094370 tn?1317134825 They changed me to synthroid bec the blood test didtn show the overmedicated so they thought it was a reaction to meds hence l 4 weeks later on synthroid equivalent dosage showed overmedicated---2 weeks test looked fine BUTMY body said something is way off.
Avatar n tn I recently switched from Synthroid to Armour and would like to know if I am taking enough Armour. I have been on 0.175 Synthroid for 13 years. My doctor recently switched me down to 0.15 because my TSH was 0.05. I had very bad headaches on this dose. Felt dizzy, like I was going to pass out all the time. I requested my doctor put me on Armour so he said that we could try it. He wanted me to be equivalent to 0.175 again so he put me on 2 grains a day. Can you tell me if this is accurate.
Avatar n tn Hi quick question due to my symptoms my endocrinologist decides to put me on Cytomel along with my synthroid. 3 months ago these were my results. T3 feee was 3.0. Standard range for my lab is 2.0-4.4. My TSH was 1.09. Standard.450-4.5. Free T4 was 1.57 standard.82-1.77. These were my results before adding the cytomel. Today these are my results. T3 2.4, TSH 1.38 and Free T4 .99. I want to know if I’m moving in the right direction?
Avatar n tn 100 levo plus 25 Cytomel is roughly equivalent to 60 mg Armour. Did you go from 50 to 100 levo in one jump? And did you add the Cytomel at the same time? It looks to me like you are taking too much T3 relative to the T4 you are taking. Your FT4 has dropped slightly, but your FT3 has risen significantly. You don't appear to have any issues with conversion. Did the Cytomel help your fatigue? My recommendation (not a doctor, just a fellow patient) would be to do one of two things.
