Is Levothyroxine T3 Or T4
I have hypothyroidism but im tired all the time and im cold alot what can I do I have normal blood levels and take levothyroxine for it T3 (liothyronine) T4 TSH ok?
Tired and cold:
It is most likely you have not been given enough thyroid medication.
If you are sure that your thyroid blood levels are OK - (how long since they were last measured?) - please see your doctor to work out why you are tired and cold.
Thyroid labs should be measured every 3-6 months. ...Read more
I've been on levothyroxine for three weeks and almost feel like my symptoms are worse. Both my t4 and my t3 (liothyronine) are low, the most bothersome symptoms ach?
Dosage adjustment: Usually, most cases of hypothyroidism are treated with increasing doses of l-thyroxin until all levels of T3 (liothyronine). T4 and TSH are normalized. This is determined by routine blood testing including checking for anti- thyroid antibodies to rule out autoimmune (Hashimoto's) thyroiditis. ...Read more
What is the question: Hi. Your thyroid function is normal on your dose of l-thyroxine (assuming you're equilibrated on your dose). What did you want to ask about? Good luck! ...Read more
I (27 years old) have a tsh=4.87, t3=1.2, t4=6.9, I wanted to know whether I should take levothyroxine or not, and if yes how much a day?
Mild hypothyroidism: Your TSH is very mildly elevated, other thyroid levels are normal. Treatment depends on symptoms. If you have gained weight, excessive fatigue, constipation, etc., treatment with thyroid hormone (25 to 50 mcg daily) may help. If you have no symptoms, it is worth waiting, and repeating the level in a few months to see if it is better or worse. ...Read moreSee 1 more doctor answer
So a TSH of 5.5 with T3 (liothyronine) of 2.8 & T4 of 0.98 (was told T3 (liothyronine) & T4 r ok) is it right to take 50mcg of levothyroxine? I also take asgwaghanda for hotflash
If you have a normal TSH and T4 levels but your T3 (liothyronine) is low do you need to increase levothyroxine?
Depends: The T3 (liothyronine) may be low before you take your medication and isn't necessarily abnormal. If you still have symptoms and the TSH is not in the low part of the normal range then adding more levothyroxine is probably the right thing to do. Some people do not convert enough of the T4 to T3 (liothyronine) and they need to take some T3 (liothyronine) in addition to T4 or take a natural thyroid med like Armour Thyroid or nature-throid. ...Read more
I'm taking 200mg of levothyroxine, my tsh is 0.1 and t3 (liothyronine) and t4 are normal. It's subclinical hiperthyrodism?
Was told to stop taking levothyroxine for 6 weeks, now blood work reads t3/2.8 t4/0.98 and tsh/5.5. Today I got call to start right away 50mcg again.
Your TSH is high:
Your TSH, thyroid stimulating hormone, is high, which means that you have an under active thyroid gland. TSH levels are the most sensitive in diagnosing low thyroid. TSH is produced in a gland in the brain called the pituitary and its level increases in response to low thyroid hormone levels in the bloodstream.
I hope this answers your question. ...Read more
Can levothyroxine 50 mg shrink multiple nodules? It brought TSH down to 0.7 uUI/ml, T3 (liothyronine) to 3.57 pmol/L, but T4=20, 3 pmol/L which is normal high range.
Was on levothyroxine 200 mcg daily for years. Recently tsh came back as 26. t3 (liothyronine) and t4 normal. Now 250 daily how long before normal tsh as due surgery?
My TSH is 0.741 uIU/ml, My T3 (liothyronine) is 1.33 ng/ml, My T4 is7.61 ug/dl. My doc prescribed me Levothyroxine 100mcg?
Each clinical laboratory has a different reference range for thyroid (and other) labs so you need to find out if the labs are normal, or above or below the range.
In my clinic your data would not warrant Levothyroxine but you need more confirmation from your doctor.
Too much of a good thing is not good for you. ...Read more
Total thyroidectomy 4 mo ago. High TSH & t4, low t3 (liothyronine). Feeling very hypo. Increases in levothyroxine not helping symptoms. Sliding downhill fast! Help!
Something does not sound right.
A high TSH with a high T4 is very uncommon.
It is possible, but unlikely that your pituitary gland is producing too much TSH.
You need to see your thyroid surgeon or your regular doctor as soon as possible. ...Read more
Hi, t3 (liothyronine) uptake: 32, t4 free 1.35, t4 11.8, FTI 3.8, TSH 2.050, im taking. 50 mcg levothyroxine. How's my thyroid, gain 40 pounds last few years?
Not your thyroid: I can't say if you needed to be started on T4 without seeing your test results before treatment but your current tests show normal thyroid levels on your current dose. It is rare for an underactive thyroid to case weight gain and when it does, the thyroid is severely underactive and weight gain is no more than 5-10 lb. So your 40 lb weight gain is likely due to lifestyle not hormonal issues ...Read more
I'm on Levothyroxine and Cytomel (liothyronine) for T3 and T4 and my blood work came back TSH w/Reflex to FT4 is 0.01 L and T4, FREE is 0.6 L. What does this mean?
Several things: Hi. Without seeing your thyroid function over time, I'd say the fact that you have a goiter & 2 cm nodule (same thing, or different?) AND taking T4 AND T3 (liothyronine), (liothyronine) you may be over-treated with T3 (liothyronine) so that your TSH is suppressed and that causes low free T4, which is not made up for by the levothyroxine you're taking. I suggest you talk with your doctor, who won't have to guess like we do! Good luck! ...Read moreSee 1 more doctor answer
My doctor says my T3 (liothyronine) and T4 levels are okay but the TSH levels are still off, what are the causes? I am taking. 088 levothyroxine daily (from. 150 to. 112 to current dose) 10 + years ago had a radio-active iodine procedure.
This: This means you need an adjustment in your dose of levothyroxine. If your TSH is up still, you need an increase your T4 dose. Your pituitary gland that makes the TSH is not getting enough T4 and T3 (liothyronine) to be happy even if those are in the "normal" range. ...Read moreSee 1 more doctor answer
I, m pregnant in the 15 week. I use levothyroxine. In week 13 my thyroid test was T3=170.7 T4=15.14 TSH=0.96 To What extent is different with 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, your test results are normal. T4 is normally higher in pregnancy. See this site for more info.

Hello I am 52y/o I have hashimoto thyroiditis I take 100mcg levothyroxine for 4 days and 50mcg for 3days of week. Tsh=0.1 T3 (liothyronine) =110 t4=10 is that ok?
Recommendation: Not knowing how you feel or your current symptoms, from the labs above, you are mildly hyperthyroid. Currently you are taking approximately 78 mcg/day of levothyroxine (550 mcg/7 days). A reasonable change would be to just take 75 mcg/day. This way, you don't have to take two different doses or cut the pills. This is again based solely on labs. Your doc who knows you best should evaluate you. ...Read more
