It depends on the person and lithium draw to see if your at toxic levels. That's what I've been told. I take 600mg and mule el is 75 if I go to 900mg it puts me over 100 lithium draw which Drs say is to high for me.
I take 450mg at night, which is pretty low. There isn't really a set dosage. It all depends on your response. It also depends on your lithium levels, which your doctor can check for you with a simple blood test.
I'm on 900mg daily. I take 300mg 3 times daily. I've been in the icu twice for toxicity because I seem to have this special super power of dehydrating very easily. I recently moved up to 1200mg daily, but that ended up being way to high for me and making me toxic again. Do now I'm back down to 900mg daily.
I take 1800mg daily …900mg for breakfast and 900mg @ night . I follow up with blood work all the time and seem to always be too low. I always have problems with dosing because my tolerance is always so high. Docs are amazed because my tolerance…wondering why I can 'take' it .
I'm on 900 Lithium and 2000 Depakote. My pdoc told me 900 on Lithium is what they start you at and then check your blood levels. I was good, so that's where they kept me. I don't sleep well, but I think it's because I get up and pee 5-6 times a night lol. Lithium side affect. I've been on it for over a year and it is absolutely necessary for me to function.
