Hello doctor,

My 24 years old daughter born without a thyroid and treated with Synthroid since birth has a TSH level of 23.980 uIU/mL and T4 Free of 1.57 mg/dl on the current dose of Synthroid 150 mcg. Her weight is 150 lbs and height 5' 4". Her endocrinologist increased her dose to 300 mcg, thinking her dose had been 250 mcg (incorrect). What is the correct dose to return to normal thyroid levels for this condition at her age and weight?

Hello,

Welcome to icliniq.com.

It is better to increase the dose by 25 mcg, i.e. 175 mcg if she was using 150 mcg till date escalating the dose or thyroid medication will be like 25 to 50 mcg at a time. Not double the dose causes severe sickness. As you mentioned, she was Synthroid (Levothyroxine). It is better to continue the medication to maintain a normal thyroid level for a long time. After using this medication 175 mcg, it is better to repeat the thyroid profile after six weeks to check for that thyroid level.
