Synthroid dosage levels
Common Questions and Answers about Synthroid dosage levels
synthroid
I hate to say it, but 2 weeks is not enough time to allow the body to get the Synthroid levels correct.
TSH levels for women can change monthly, and in fact, even daily. If you had a blood test done at say, 9am and another one two weeks later at 3pm then the TSH will be totally different. It always best to get tested at around the same time each time. This then gives a better reading. TSH rises during the day.
I know it is a pain, but honestly wait a few more weeks then get tested again.
1 Synthroid, with annual thyroid blood tests. When my TSH levels drop or rise above the normal range, the doctor adjusts my Synthroid dosage. I also have uncomfortable symptoms when I am not in the normal TSH range.
Recently the doctor changed my Prempro dosage from .45/1.5 mg per day to double that amount. Do you think the change in Prempro could change my thyroid levels?
Should I request new thyroid blood tests or wait for my annual testing which comes up in 6 months?
I was prescribed 50mg Synthroid to take daily because of thyroid levels. I took a blood test a month after starting the medication to see the difference. I always felt tired and my weight keeps increasing despite being careful with what I eat and doing exercise several times a week.
I felt a little better but I received the test results today and my doctor explained I had to see an endocrine (sp?) specialist to review my situation. He said the medication I was taking was not enough.
I am very good about taking my meds and get my blood taken periodically to check TSH levels. I have been on .88 of synthroid now for the last 10 months. I recently went to my gyno and he took some blood to check my tsh because I was there. I usually go to another doctor but I let him take the blood. My results came back with a tsh of .12. They wanted to raise my synthroid to .1 . Shouldn't they want to lower the dosage? Thanks for listening.
Hello. I was wondering if I could get your opinion. I was on 112 mg of Synthroid. My results were as follows:
TSH .87 (.67-4.5)
Free T4 1.17
I feel a little hyper. I suspect that I do better with my TSH a little higher. Would the next step be to drop down to 100 mg of Synthroid? Thank you for your opinion.
I have been on Synthroid 0.1mcg for the past 16 years. I have TSH levels drawn every 4-6 months which have always been on the low-normal side with no change in my medication. The last TSH drawn was 0.333 in September. I have been experiencing about 4 days of PAC's/PVC's quite constant, and am wondering if this is due to the low TSH level? I called my PCP who told me to stop the 0.1 mcg of Synthroid and that he was going to change my dosage to 0.75 mcg.
I had the exact same problem of severe toe/foot/lower leg cramps that sometimes scared me. These started a couple of years after I started Synthroid. (The Synthroid saved me.) But my doctor should have told me what two of my friends told me who take Sythroid--that I needed to take Magnesium. Within a week or two the cramps were all gone, and my fatigue level was better. I'm SO THANKFUL! (I always take the Mag.
Hello. I was wondering if I could get some advice on my current dose of Synthroid. 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.
Your hypothalamus, which is located near your brain, is the organ responsible for stasis (keeping things constant in the body), so it regulates things like body temperature and thyroid hormone levels. Your hypothalamus checks your thyroid levels and sends a message to your pituitary if they're too low. The pituitary, in turn, produces TSH, which is its messenger to the thyroid. So, any disturbance in the hypothalamus or pituitary can also affect TSH.
My first TSH reading post-thyroidectomy was 27. We are increasing my dosage from 125 to 175. I have gained 10 pounds since surgery and radio-iodine treatment. Does increased dosage help with weight loss?
I spent the night in the ER about 4 weeks ago after having chest pains and was told that my TSH level was at 63. They gave me IV synthroid and told to take my prescribed dosage. I followed up with my GP and was told to increase my dosage of synthroid to 150 mg until they got my blood work back. The next day my GP told me to take 150 mg 6 days a week and 300 mg on the 7th. After 3.5 weeks (while at the gym) I started to have chest discomfort.
What are the reference ranges for the FT3 and FT4? These vary from lab to lab, so must come from your own report.
I'm not sure why your doctor would tell you to go completely off the synthroid; would probably have been better to adjust your dosage instead. You have to be consistent in taking the med or you will never know what's working or what isn't.
Could I get some help with my results and dosage of Synthroid? (I had Graves in 1993 and missed to check my blood months ago so I went into the hypo zone with TSH =52 in May). here my current situation:
8/4/2010 - TSH = 4.62 (I was recommended .125 Synthroid)
8/30/2010 TSH = 0.33 (moved to .112 mg Synthroid)
9/14/2010 TSH = 0.358 (moved to .100 mg Synthroid)
Does it seem ok to you to land me in the right range?
I had a total thyroidectomy in sept 09 for thyroid cancer, followed by RAI in november. My levels haven't been normal since. My TSH is 0.03 my thyrogloulin is 0.2. I am on 175 of synthroid. I just had my scan of neck and somethng showed up on right side? Not sure what yet, going to talk to doctor on monday. Any thoughts??
t had her thyroid
As you know D3 levels are low. But also so are th B-12 levels. Many countries the B-12 low end of the reference range do not even start until 500. And many people do not feel well until their B-12 is towards the upper end of the range. Certainly above 700 if not above 900. So it may make sense to also start to supplement with sublingual B-12.
Your thyroid tests and symptoms are consistent with Hypo. So starting on thyroid meds seems like a good thing to have done.
I was put on 150 mcg of Synthroid for over a year and recently received a call from my doctor saying my levels were low and prescribed me 125 mcg of Synthroid. I don't understand why he did that. Isn't 150 mcg a higher dosage than 125 mcg?
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.
There is more we need to discuss, but before gong further, please tell us your daily dosage of Synthroid. Also, please tell us about symptoms you are having. Also, if any other thyroid related tests besides, TSH, please post those, along with reference ranges. Also, if tested for Vitamin D, B12 and ferritin, please post those as well. If not tested for those three, then you should also make sue the doctor tests those at next opportunity.
My total thyroid was removed because of Cancer. I have gone through Radiation Abliation and am cancer free. I am on Synthroid .50 five days a week & .75 for two days. My dosage has been changed several times. I would like to know what would be the correct dosage if I change to Nature-Throid? The conversion chart is confusing? I am having problems getting my levels correct. Will Nature-Throid work to suppress recurrence of cancer and work better to level the TSH, T3, & T4?
