Do you increase levothyroxine if TSH is high?

If the TSH is not at the desired goal, the levothyroxine dose can be adjusted up or down. TSH values that are slightly out of range may be corrected by a single dose increment or decrement, such as increasing from 100 to 112 μg or decreasing from 175 to 150 μg.

What are the symptoms of too much levothyroxine?

How much Levothyroxine should I take to maintain normal TSH?

Those taking more than 125 mcg of L-T 4 per day were much less likely to maintain normal TSH levels over time than those taking less than 125 mcg per day. At 1 year, 91% of the patients taking daily doses of 125 mcg or less continued to have a normal TSH, while only 73% of patients taking more than 125 mcg per day had normal TSH.

How to calculate levothyroxine dose for desiccated thyroid?

To attain this theoretical ratio, I would need to add 10% of 88 mcg, or 8.8 mcg of T3. A dose of 1 grain of desiccated thyroid + 50 mcg levothyroxine equals 88 mcg T4 + 9 mcg T3, which is what I’m currently taking.

How to know if your levothyroxine dose is too high?

Any change in dose should be gradual, or signs of overmedication (like high blood pressure) could appear. Deep sleep and waking rested is a sign that your dose may be optimal. Poor sleep with constant waking could mean either your T3 dose is too high or your T4 dose is too low. Or your sex hormones may be too low.

Is it normal to take 125 MCG of L-T 4 per day?

The study found that the only risk factor for having an abnormal TSH level was the dose of L-T 4 that a patient was taking. Those taking more than 125 mcg of L-T 4 per day were much less likely to maintain normal TSH levels over time than those taking less than 125 mcg per day.
