Common Questions and Answers about Synthroid dosage mcg
synthroid
Great thankss alot.. I'l check it today.
Yes I was at 25 and went up to 25. You mentioned dosage is done in 12 to 25 mcg increments. That make sense, thanks.
1 mcg of Synthroid and that he was going to change my dosage to 0.75 mcg. If my TSH level is already low, wouldn't lowering my dosage of Synthroid make this level even lower? Are palpitations a symptom of low TSH? I am due to have a repeat TSH in 2 months at which time I will ask the M.D. to add a T3 and T4 (these have not been drawn for some time).....
I was on 88 mcg with a TSH of 5.8. I was increased to 100 mcg. I have been on 100 for 3 weeks. I went ahead and tested my TSH after only 3 weeks because I wasn't feeling great. I did not test Free's. The TSH is now 3.44. My symptoms are anxiety, constipation, interrupted sleep, etc. Do you think it is too early to see if I might need a little more, or would waiting 3 more weeks really make a difference in TSH. Thank you in advance. I also take iron for low ferritin.
I would like to know who out there has been on my same dosage w/Synthroid and what dosage are you on w/ Armour? I know everone is different. The only symptom I have that is different, is I have a deep hunger in my stomach that wakes me up at night and is almost painful (painfully hungry). I am still tired.
1.7 mcg/kg/day is a guideline for initial dosing when first starting on levo. Once on meds, dosage has to be used to manipulate FT3 and FT4 levels to achieve elimination of symptoms. Many doctors do not realize that their patients will not be symptom-free just because their FT3 and FT4 are "in range". Many of us feel best when FT4 is about midrange and FT3 is in the upper half to upper third of its range.
I am curious if there is some formula for syntroud dosage. I was on 88 mcg and my tsh has gone up from 4 to 17. He is raising my dosage from 88 to 125 and will retest later. He said it's better to raise it slowly if that's not enough. Is there any way to know how much I will need? I have hashimotos and my tsh started at 6 went to 3 with synthesis then up to 40 then back down to 4 with more synth road and now up to 17. Please don't ask for t3 or 4 I don't know it .
Hello. I was wondering if I could get an opinion. I was on 112 mg of Synthroid. My results were as follows:
TSH .87 (.67 - 4.5)
Free T4 1.2 (.67 - 1.76)
I was feeling a little bit hyper on this dosage. I was nervous, not sleeping , etc. I think that I seem to do better when my TSH is a little higher. I already had 100 mg of Synthroid, so I started taking the 100's, with the knowledge of my doctor, but by day 3, I was crying, emotional, and not feeling good at all.
I had my thyroid removed on october 24th and have been on synthroid 75 mcg since. i have been having cramps in my calves like charlie horse pain for the past week . Does this mean that i may need a higher dose of synthroid. I just went and had my first lab work done since my surgery this past week. I have noticed that I have gained some weight since the surgery.
My mail order pharmacy sent me 0.75mg of levothyroxine instead of the 0.75mcg which is the correct dosage, I have taken almost the entire bottle, I need a refill this how I noticed the dosage was wrong. Is there a big difference between mcg and mg? Could this be harmful?
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.
Started taking 1/4 pill for 4 days (ie 25 mcg) , 1/2 pill (50 mcg) for 2 days and 100 mcg for 4 days. I started taking lower dosage because I have some allergies to meds and I always start out low to make sure I am not allergic. After 4 days of 100 mcg I woke up early around 4:30am to go to restroom and I was so dizzy I fell. Did not fall hard or hit my head. I felt dizzy all day yesterday. I did not take synthroid thinking that was only thing I changed.
Call him back, and talk directly to him, esp if you didn't before. Alot of times the "nurses" that you talk to are not real nurses. They are medical assistants and some have had no formal training. Yes 125 mcgs is lower dose than 150 mcg.
One grain (60mg) of Armour contains 38 mcg of T4 and 9 mcg of T3. So your current dosage totals approx. 76 mcg of T4 and 18 mcg of T3. If the doctor is trying to increase your FT3 level by switching you to Synthroid and Cytomel, why is your new dosage lower in T3, but with a big increase in T4. If you are already not adequately converting T4 to T3, resulting in FT3 lower than wanted, then I don't see how this helps at all.
My wife was diagnised as hypothyroid several years ago, although she had no antibodies. She started taking 75 MCG of Synthroid, and has been taking it ever since. Despite irregular periods, she was able to get pregnant and he had a healthy baby (she continued the synthroid thruogh pregnancy and her levels were normal).
However, 14 months after the baby was born she is exhibiting many sympoms of HYPERthyroidism -- sleeplessness, weight loss, and significant anxiety.
I am really having a terrible time adjusting to the change - it has been about 12 days - I was on 50 mcg (low dose) and upped it to 75 mcg four days ago. How long, in those of you with a lot of knowledge, does it take for the body to adjust. I know that I now don't have the T3 from the Armour - but when do you think I would notice how I am going to end up feeling on a certain dosage? Since med upped to 75 mcg I feel only a tiny bit better - and that is still not very good at all.
So I finally got diagnosed with Hypothyroidism and just picked up my prescription of Synthroid, the problem is, it's 100mcg and the doctor said she would start me out on a low dose. I was under the impression it would be in the 25-50 mcg range. My question is, is it too high of a dose? If it is how do I know? Do I break it in half? Agh, the confusion!
I guess the best answer to your question would be "It depends". It depends on the severity of the hypothyroidism, the initial blood levels of the biologically active thyroid hormones (Free T3 and Free T4), the dosage of Synthroid, and the response of the specific patient to the Synthroid.
If you will post your thyroid test results and their reference ranges, your symptoms of being hypothyroid, and your dosage of Synthroid, perhaps a member can narrow it down a bit.
It is my opinion that you are not getting quite enough synthroid. First, synthroid doses are more typically 100 to 125 mcg. Second, if "anxiety" is really elevated irregular heart beat or atrial fibrillation - that can be caused by hyothyroidism. Certainly fatigue can be due to hypothyroidism. Third, your TSH of 3.8 is a little high in June indicates that your body is asking for more. At best, you are getting the absolute bare minimum amount of synthroid.
