Hello Ron,
Lithlium carbonate should not be given to a pregnant woman
mainly in the first trimester if we can avoid it and the same goes for
many chemicals, even aspirin.
BUT, let us not forget that the usual dosage used to treat patients with
bipolar disease varies as follows:
150 to 600 mgs three to for times per day, maximum amount being
2400 mg per day.
This is a hell of a lot more than what may be picked up from a fired glaz=
e
containing lithium.
Later,
