Question: Do I need Thyroid Medication ??
|ritu74 - Sun Oct 14, 2007 8:54 am|
Hello, I am 33 years old female.
I was recently diagnosed for Thyroid on 20th july 07 and put on medication Levoxyl 0.05 mg once daily on empty stomach.
When this medication was prescribed my test report was as follows :
ON 20th July 07
Test Result REference Range
T-4, Free : 1.0 (0.8 - 1.8ng/dL)
TSH W/REFLEX To FT4 5.76 (>20 yrs : 0.40 -5.50 mIU/L)
After these results Levoxyl 0.05 mg once a day was prescribed .
ON 12th Sept 07 the test results wereTest Result REference Range
T-4, Free : 1.8 (0.8 - 1.8ng/dL)
TSH ,3rd Generation 0.02 (>20 yrs : 0.40 - 4.50 mIU/L)
After these results Levoxyl was reduced to half from 0.05 mg to 0.025 mg daily.
With this medication my periods have not stopped. I am having them regularily since 24th August.
They just stopped for a few days .
I was wondering whether the thyroid medication was really needed as prescribed as the results didn't seem so out of range.

TSH (thyroid stimulating hormone) is the most sensitive measure of the bodies balance of thyroid hormone. If TSH is high the body needs more. If it's low the body has too much. In your case, your initial free T4 was normal and the TSH was only very slightly elevated. This would indicate a condition called subclinical hypothyroidism. Many endocrinologists now are recommending treatment of this condition with thyroid hormone because they've found that people feel better even though they didn't really feel bad before.
Your TSH was so close to normal I would likely have simply repeated the tests in a few weeks to see if it was normal. However, starting medications is also reasonable.
Reducing your dose after the second set of tests was appropriate. At that point you were clearly getting too much thyroid hormone as your TSH was low. You should have your levels checked again in 2-4 weeks on this dose to see if this one is correct.
You may want to talk with your doctor about stopping the medicine to see if your levels stay normal. However, do not stop the medicine on your own. This should only be done in consultation with your doctor.

Thanks doctor for such a prompt reply. I will definitely get the test done soon. Another related problem was my mensus. Do you feel it is because of the thyoid hormones changing so much.
Also, I was planning for pregnancy during this period. It has become very difficult to plan as the cycle is no not regular at all.
What could be done about it ? Thanks a lot.
