Is synthroid for hypo or hyperthyroid

Common Questions and Answers about Is synthroid for hypo or hyperthyroid

synthroid

Avatar_m_tn Is it standard procedure to use Synthroid on normal TSH, + or - hyper/hypo levels. What is considered normal ranges for prescribing synthroid for an enlarged thyroid.
Avatar_n_tn It depends on the cause. If it is Graves, then the other option is anti-thyroid drugs. If toxic nodule(s) then usually I-131 or surgery are best options. If it is thyroiditis there is no treatment other than controlling the symtpoms as this resolves on its own in 4-8 weeks usually.
Avatar_n_tn i am 44 yr old female 174 lbs. on tapazole 5 mg for 2 yrs now.I had goiter & have 3 nodgles.My TSH on tapazole has stayed center of normal range.My old endo. said I could stay on tapazole 2 yrs then I would need radiation or surgery, is that true?My TSH 2 ys ago was .04 & .12.Also in 1999 I had hypo & took synthroid for a yr. I had many health problems so is there a chance my health could be related?I have temperture problems,hormone symptoms,neurologic,vision,digestive.
Avatar_n_tn Four years later, I was diagnosed with Hashimoto's and tested positive for antibodies. Went on Synthroid and had my dosage increased over the years from 75mcg up to 137mcg in October 2007. Shortly after my dosage increase in in Oct - around Halloween, I began experiencing sinus tachycardia, high blood pressure, anxiety, restlessness, racing thoughts, etc. All the symptoms of hyperthyroidism.
Avatar_f_tn If your diagnosis ist Struma nodosa toxica or Adenoma toxicum glandulae thyreoideae or it is Imunohyperthyreosis which can not be regulated with thyreostatics (lasting more than 1 year despit thyreostatic therapy or after withdrawel thyreostatic th) ,than is a better choice radioiodine therapy
Avatar_f_tn 01 .Also my 4-24 hrs uptake scan report shows for 6.3 hrs -uptake is 37.9% and for 24.1 hrs it is 75.8% what does it mean.
Avatar_f_tn Good news, was great, it was not cancerous, BUT when he left a message, he told me to just take my Synthroid 50mcg. With really no diagnosis if this is hyper or hypo, I decided to pull up my records (which you can do at this one hospital facility. But hey, why not, it's my own information) and the radiologist says at the end of his results that I have Hyperthyroid which he suggest Grave Disease. I tried to call my dr and ask lots of questions, but their office was close early.
Avatar_f_tn Hypo for 15 years started at 50 synthroid then 100 synthroid 5 years ago. No to Hash's. They just found out I was Hyper 5 weeks ago thru routine yearly check. Just wondering when TSH would start to go back to normal levels. Heart doc will not do cardioversion til levels of TSH and FT4 are normal. FT4 is getting there but TSH hasn't moved in 5 weeks.
Avatar_m_tn Yes, it's normal for doctors to prescribe anti-depressants when one is, either, hyper or hypo, because depression is one of those symptoms that applies to both and many doctors prefer to prescribe anti-depressants over thyroid hormones. Is this a normal reaction when stopping Synthroid? There is no "normal" reaction to stopping Synthroid, because most people don't stop it or if they do, they're changing to a different replacement thyroid med.
Avatar_n_tn My husband has been taking Synthroid for five years now due to an underactive thyroid. He has always looked more like an overactive thyroid patient in that he is very thin 6'.0" @ 160 lbs. He does have prominent eyes and has been asked by many doctors if ever diagnosed with hyperthyroidism. He has been experiencing symptoms that we now see are consistant with hyperthyroidism for a couple of months. He had his level checked today and the T4 was 17, normal was said to be 6.1 - 12.2.
Avatar_m_tn Get your labs from Jan 14 in your possession and post them. Something is just not jiving. Synthroid increases thyroid function so if hyperthyroid - you will stay hyperthyroid on it.
Avatar_n_tn Prior to your surgery, you were likely Hyperthyroid,(Overactive) once it is removed you become Hypothyroid (Underactive) now you are experiencing hypo symptoms, most Md's start you off on thyroid meds, and then six weeks later re-test to make adjustments in medication, thyroid hormone therapy takes a little while to get into your system. Have you discussed these symptoms with your MD?
Avatar_n_tn The T3 is tough to follow -- it will peak about 2-3 hours after the dose of armour or cytomel -- in other words, interpretation depends entirely upon knowing dose timing. The hair symptoms may take months to resolve even if you find the right combo/dose immediately. I prefer cytomel/synthroid combo b/c I can control the T4/T3 much better than with armour.
Avatar_f_tn The only way I'd be able to tell if my thyroid could have recovered (face it it's not going to now) was to go completely off the synthroid for a few months. However - the rapid weight gain aspect of the whole thing is so dreadful I couldn't do it. I'm sorry Trish that this happened to you. I actually enjoyed being hyper but hypo.........no, who needs help being MORE tired and gaining MORE weight.
Avatar_n_tn Should I reduce the dose of Synthroid from 0.5 to 0.25 not to become hyperthyroid? What is the risk of becoming hyperthyroid at this stage? Thank you very much.
Avatar_n_tn Is it normal to experience hyperthyroid-like symptoms upon an increase of Synthroid, which then disappear? And then feel hypo again as it "wears off"? I was officially dx'd as hypo in the winter (after having had Graves some 20 years ago, and then hypo symptoms for years but told the labs were normal).
1440512_tn?1294475233 Im sorry. I must have mistyped. i'm not experiencing a weight gain but a severe weight loss. I've lost 100lbs so far. I lost 12 just last week. The dr won't even entertain retesting. I had to quit taking the synthroid because it was making me lose faster. I know I'm dehydrated because my lips and mouth are very dry and you can pinch the skin on top of my hand and it stays. For some reason I've cut my fluid intake in half. This naseau thing started 3 weeks ago and I can't seem to tolerate it.
Avatar_n_tn Some of the symptoms can be the same for either hyper or hypo, I believe. My TSH is only 0.02 at present, but my FT levels are about mid range......so we don't mess with the dosage.
Avatar_n_tn I was diagnosed with Graves at 24. Had RAI by the age of 26 and have been taking Synthroid sice I was 28. My TSH is .044 and I know that is low. It has been there a few years because this is usually where I feel good. I was higher for a few years and still battled with weight and other Hypo issues. I am very healthy. I eat well and work out several times a week. Over the past year I have been dealing with some issues that I thought were maybe related to menopause.
Avatar_n_tn 112 IS THE LOWEST I HAVE EVER TAKEN IN 8 YEARS FOR HYPO. MY QUESTION IS CAN ALL THESE SYMPTOMS BE RELATED TO MY TSH LEVEL BEING A LITTLE LOW AND IF I GOTO .100 DOSAGE IS THAT SMALL OF A DECREASE ENOUGH TO SEE A DIFFERENCE IN SYPTOMS? CAN SYMPTOMS APPEAR AND DISAPPEAR FROM SUCH SMALL DOSAGE CHANGES?
Avatar_f_tn My guess, until we can see some labs, is that your doctor isn't giving you enough Synthroid, thus your hypo symptoms of swelling in the extremities, itchiness (from dry skin?) and intolerance to cold. Other of the more common symptoms of hypo include hair loss, weight gain, constipation, depression and fatigue or sleepiness (despite adequate or excessive sleep). It would be interesting to see your test results for FREE T3 (FT3), FREE T4 (FT4) and TSH.
Avatar_f_tn Has anyone taken too much Synthroid? Too much that it made you hyperthyroid? What symptoms did you have and for how long?
Avatar_f_tn So my question is have I just been on too high of a dose or is there a way I could have both hypo and and hyper thyroid? I have read a little on postpartum thyroiditis but not sure if I could still have that... my baby is 6 montns old. If anyone could shed some light here I would appreciate it!
Avatar_n_tn I saw the endo for initial eval with all the symptoms wt loss, heart palpatations, heat intolerance, anxiety/depression (is bad), tremors, brain fog, focus problems. It is getting harder for me to function on a daily basis. I want to start treatment quickly b/c I know there is no quick result. He explained all 3 options but of course favors RAI. He made my next appt in May 06. So I guess I just decide and tell him over the phone. His asst. asked if I had decided on treatment.
Avatar_n_tn You should take it. It will only be for a short time. Can it make you hypo? Yes, just like Synthroid can make you hyper. You will need to monitored so the dosage does not drive you hypo. You are going to have periods of hypo and periods of hyper, both from your gland being unhealthy, and also from medications being wrong. It is unavoidable. The goal should be to make those swings as few and as small as possible. Right now you are severely hyper.
Avatar_n_tn This is down from my results in October 2008 of .4. How concerned should I be about this? Is there any real risk to me or my child. What is it I should be making sure that my doctor is doing or looking at? Are there any specific questions I should be asking? Thank you very much.
Avatar_m_tn A surgeon will put you on anti-thyroid meds to get your thyroid normal before surgery (opposite to what's required for RAI - where the uptake is hopefully only going to be taken by the nodule - so they want the nodule 'hungry' for the iodine and the rest of the glad suppressed. The wait and see, if the nodule is small, and the labs look pretty normal, means that the rest of the thyroid is probably not suppressed yet (the nodule takes over producing the hormone).
889468_tn?1241571223 Since RAI and TT, I have no problems at all of fast heart rate, tachycardia, bradycardia and for the first time in nearly 50 years, I have no problems with irregular heartrate and doing great on T4 med. In regards to T3, it is ok for some but not for all....just as Armour is the same. Chel The fast heart rate can be caused by excessive T3. That is the reason I had Thyroid Storm. I am great on T4 and converting very well.
Avatar_n_tn Do you mean serum T3 or serum T4? There is no serum t34. And is that result of 10, free or total? What's the reference range for it? Reference ranges vary lab to lab and have to come from your own report.
Avatar_f_tn Thanks for your responses. I started with hypo symptoms and a TSH of 5.05 and was given 50 mcg of Synthroid in May 2011. I continued to have fatigue, brain fog, weight gain etc... Then my next blood test, 8 weeks later, revealed my TSH only dropped to a 4.65 so the doctor decided to increase dosage up to 75 mcg due to my symptoms. Then, two weeks later she increased my dosage again to 88 mcg. In addition, I also decided to go gluten and grain free.
