Hi there, thanks for asking. lithium
could cause sick sinus syndrome
which causes low heart beat. The people who find this issue will find light headedness as you mentioned. Lyrica
can be used with lithium. You can also use lotrel
with it, the only anti hypertensive medications which should be used with caution in case somebody is taking lithium are diuretics. Loratab is better not to be taken regularly and other ways to control the pain are used. However it does not cause any problem with lithium. I wish you a good health.
