What Is The Ideal Dosage For Thyronorm Taken For Thyroid?

Posted on Thu, 14 Apr 2016

Question: I had Papillary CA - and hence went through surgery. Later had a radio iodine treatment also. Now taking thyroid medicine (Thyronorm 150 mcg). I was taking 1 tablet each till one month back. Based on doctor suggestion, carried a TSH test; and found value as 0.1 u; instead of normal of 0.4 u + required. Hence, doctor suggested to take 1 tablet daily for all days escept Sunday; and take 2 tablet for Sunday. Is this correct dosage? I am feeling some hair loss and weight loss now; am not sure whether I am having any Hyper or Hype thyroid issue.

Brief Answer:
In papillary carcinoma thyroid we keep the TSH lower than normal

Detailed Answer:
Hi,

Welcome to HCM. I have gone through your questions and understand your concerns.

After thyroid surgery, you are hypothyroid. In papillary carcinoma thyroid we give higher dose of thyroxine ( Thyronorm) to keep the TSH low so that you won't have a recurrence of cancer.

The TSH value is kept below 0.1 in high risk papillary carcinoma, below 0.5 in intermediate risk and below 2 in low risk carcinoma. Probably you are having high risk papillary carcinoma and your doctor has increased the dose of thyroxine to bring the TSH below 0.1.

The priority in papillary carcinoma is given for prevention of recurrence. Hair loss may not be related to thyroid illness.

Hope I have answered your questions. If you have any further questions, I will be pleased to help you.

Regards
Dr Ajish TP
