    If my lithium dosage is decreased from 900mg to 600mg, how long before my blood levels will reflect that decrease? Also, what is a theraputic level?

    According to one doctor on the internet Lithium has a half life of 24 hours. He stated it takes about 5 half-lives for a drug to completely your system so it will take about 5 days to get to 600 mg. By the second day it should be at 750, then 675, 637, 618 etc. - so it gets down pretty quickly. 


    Your doctor would have to determine what a good therapeutic level is...good luck!
