The common lithium doses currently given daily for bipolar disorder (1200 mg) may be too high and in long-term prescription causing renal tube damage, hypothyroidism, cardiac disturbance, and the common lithium carbonate side effects. If low doses from 150 mg to 300 mg have a good stabilizing patient response, it is prudent to avoid high, chronic, doses. From personal anecdotal test- so far so good; Has anyone been advised on this by their physician?
