Too Low Of A Dose Of Synthroid
How long after getting proper dose of synthroid (thyroxine) should I begin to feel less symptomatic? last tsh was 23.
Usually on the order: Of two to three weeks. But I should warn you there are some patients that some neuromuscular and psychiatric symptoms can take months to resolve. It's also possible that some symptoms thought to be related to hypothroidism like fatigue or weight, may in fact be related to other factors/issues, even when the hypothyroidism is corrected. ...Read more

Is it possible to stop taking thyroxine if starded at low dose and fof no more than 40 days ? Tsh was 3.2 when starting
OK: Should be no problem. Your thyroid function was actually normal when you started it. You do not need thyroid supplement. ...Read more
Can you stop taking Synthroid (thyroxine) after (5-6)years of taking it? Borderline -low TSH is why it was prescribed. Dose .050mcg.
Synthroid (thyroxine): You must mean a borderline high TSH for an underactive thyroid. Anyhow, the thyroid does not revert back to its normal level on its own, it ages with us and needs frequent monitoring, i would suggest not to stop it, but this is something you need to discuss with your doctor who knows you best. ...Read more
Tsh has gone to .007 to .02 now .07 still very low! my Synthroid (thyroxine) 88 my lowest dose ever. Is this showing another problem? Pituitary?
Appropriate: Your TSH level should go higher (as it has) as your dose of thyroid hormone is lowered. Tsh, a pituitary hormone which regulates thyroid output, moves inversely with the level of thyroid hormone. You latest level indicates your current dose of medicine is still higher than you need. You may need a very small dose. It's even possible that, at least for a while, you may need none at all. ...Read more
Yes: No problem with this combination.Get a more detailed answer ›
TSH was 4.54. Repeated 4 months later and now is 5.01 (lab range 0.45-4.50). Any concern? Dr wants to do low dose synthroid. Only symptoms fatigue
Numbers are numbers: Lab result numbers are just numbers, so one needs to see the whole picture. A TSH above 4 can mean a person's thyroid gland is having trouble producing enough thyroid hormone. Some patients have symptoms of low thyroid hormones (hypothyroidism) with TSH values in the 3's and 4's... and need to take Synthroid medication. That is why a doctor's evaluation and care is helpful and necessary. ...Read more
Does normal (1.01) "thyroxine (t4) free, direct, s, " normal (0.931) "tsh, " and low (67) "triiodothyronine (t3)" = Synthroid dose good? Or go up/down?
Ws hypothyroid with TSH 4.57 and ft4 1.2.With Synthroid (thyroxine) adjustments,nw my TSH is low=0.03 and fT4=2.3.Reduced Synthroid (thyroxine) dose nw.Can I try to conceive?
normal Total T4, T3 (liothyronine) Uptake, FTI, Ultrasensitive TSH
LOW Total T3 (liothyronine) (63.55 ng/dl)
Synthroid dose needs to increase?
It's OK: Hi. Your TSH is "normal", but I'd shoot for a value on therapy generally around the 1.0-1.5 range. The total T4, T3 (liothyronine) resin uptake, and FTI are prehistoric tests no one in the thyroid field has used for years. Your body regulates conversion of T4 to T3 (liothyronine), so your T3 (liothyronine) should be just what the body ordered. Your T3 (liothyronine) is close to the normal range; if you repeat it it's likely to be within normal range. ...Read more
Im 36y/o, ttc>9mos. Tsh =0.9 three yrs ago, now its 2.5. Should i be on a low dose Synthroid (thyroxine) to improve fertility? Been having hair loss & cold intol
TSH 2.5 is normal: A TSH of 2.5 indicates normal thyroid status, assuming that the pituitary is working normally. An evaluation to check this assumption out might be worthwhile at this point. ...Read more
Hair loss for 18 months in crown area, first due to stress, then perhaps due to very low TSH as a result of Thyroxine dose increase. Iron levels fine. Hair is now finer / softer and continues to shed - will my hair ever go back to how it was ?
Wrong assumptions: Iron level not relevant. "Stress" probably not a factor. Very low TSH because of overdosed thyroid probably not part of it. Thin hair on top is very common as women get older. Other meds? Birth control? Menstrual history? Pregnancies? Weight change? When you see a dermatologist be prepared to detail these items. You might be helped by spironolactone or dutasteride. ...Read more
Is it possible that even though a dose of synthroid worked for me for a while that it now needs to be increased ? I've noticed symptoms coming back
Yes: The function of the thyroid gland is not stagnant and can change over time. If you have a return of more symptoms - please advise your medical provider. Take care. ...Read more
Very possible: See your physician for blood wk ; exam. ...Read more

No. You should be ok. Side effects of too much thyroid include: rapid heartrate, chest pain, fatigue, sweating. It should be temporary.
You really need to make sure that you don't do this again. I suggest using a 7 day pill box to help remind you whether you took the medicine already or not. Best wishes. ...Read more

My dr priscribed me 37.5mcg thyroxine dose.i don't want cut 75mcgpill so can i take 75mcg pill every second day for same result?
Yes: Thyroid hormone has a very long "half-life". It will make no difference taking 75 mcg very other day vs 1/2 pill every day. However, a dose of 37.5 mcg daily is a very small dose for someone in your age group. If 75 mcg was too high a dose, you could be on 50 mcg as the next step down. ...Read more

However, you could take 1/2 of a 75 mcg if you like, or take 75 mcg every other day. The result would be the same. I don't know about the availability is in the uk. ...Read more
TSH=0.04(0.4-4.5mIU/L)FreeT4=1.5(0.8-1.8ng/dL)FreeT3=2.5(2.3-4.2pg/mL). Have Hashimotos disease, on 112mcg Synthroid. why is tsh so low FT3/FT4 normal?
All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, just one parameter, in this case TSH, slightly out of whack is not a cause for alarm. You may watch and wait. If your clinical situation changes it may warrant repeating the tests.
Wish you good health! ...Read more
