QUESTION:
Dear Dr. Heller,
I am concerned about my friend who is depressed and would like to know if a full bottle of Lithium could kill her (approximately 300mg a night with a bottle that has a month's supply) of the drug .
ANSWER:
Yes, lithium overdose can be fatal. The toxic range is not much higher than the therapeutic range. An overdose requires aggressive treatment to save the individual's life.
