How much time do a steady dose of T4 need to reach full effect on symptoms? It is stated 6 weeks, but I read posts here that for some people 2-3 weeks are enough to see final result after dose change. Given Levo's half-life period of 7 days, most of T4 - roughly 80% - will be accumulated in 3 weeks. So is it really needed to wait full 6 weeks?
And if patient feels great after 3 weeks on a steady dose, could this dose be too big for him after 6 weeks, because of the cumulative effect?
I've read Dr. Blanchard's book where he describes using the jump-start to speed up the accumulation of Levo in blood and to see final result quicker. To do this a patient should increase his dose of T4 by 50 - 100% for several days and then bring the dose back to slightly higher dose than before. Dr. Blanchard said that results of the slight increase will be seen in 2-3 weeks. Has somebody tried this method? Does it seem logical?
