Levothyroxine Dosage

Can someone please explain what the difference is between taking 100mg of levothyroxine 7 days a week versus taking 112mg of levothyroxine 4 1/2 days a week? I was originally taking 110 mg everyday and then my endo increased it to 112 mg everyday. After lab work showed my TSH level was now under the normal range my endo told me to take 112 mg 4 1/2 days a week (M, T, F, Sat and 1/2 on Sun). Is there a reason for not taking it two days in a row? Although the mg are higher the weekly total has actually decreased. So what is the reasoning behind the way endo's have to take this medication?

Hello, Erika! How are you?

Your doctor is trying to keep your levels in the normal range, without going too high or too low. It's been found that dosing this way can work better, in some people, than taking doses every day.

This medication so listed by the FDA as being used to treat thyroid disorders and typical side effects may possibly include nausea, dizziness, weight changes and hair loss.

Is there anything else I can help with?
