Lithium carbonate (Eskalith, Lithane, and Lithobid) is effective in
balancing mood in people with
bipolar disorder. How it works is not completely
understood. It may affect certain brain chemicals (neurotransmitters) that cause mood changes.
Common side effects of lithium carbonate include:
- Nausea, loss of appetite, feeling of fullness or
swollen stomach, and/or stomach upset.
- Dry mouth, increased thirst,
and increased urination.
- Headache, slight memory loss, or
confusion.
- Sensitivity to cold.
- Tiredness and
sleepiness.
- Weight gain.
- Slight hand tremor.
Lithium carbonate is a salt and acts like other salts (such as
sodium) in the body. Any change in the balance between body salts and liquids
(mostly water) in the body can change the amount of lithium carbonate in the
blood. Lithium carbonate blood levels need to be kept within a safe range. High
levels can cause serious side effects, even death; low levels can cause
symptoms of mania or depression. You will need to learn how to keep your
lithium carbonate blood levels at a safe and effective level and to recognize
the signs of
high lithium carbonate, which include drowsiness,
muscle twitching, and diarrhea.
It is very important to have your blood tested regularly (from every
week to every 6 or 12 months) to check lithium carbonate blood levels.
You also need to be aware of the following.
- Because lithium carbonate may make you tired and
less alert, avoid driving a car or using other dangerous machinery until you
know how lithium affects you.
- Lithium carbonate increases your risk
of having a baby with certain types of birth defects. Talk to your doctor
before trying to become pregnant.
- Breast-feeding while on lithium
carbonate is usually not recommended since high levels of the medication have
been found in breast milk. Talk to your doctor if you want to breast-feed while
on lithium.
- Do not drink alcohol if you are taking lithium
carbonate. Lithium can hide the signs of alcohol intoxication; your blood
alcohol levels could become dangerously high if you drink while taking this
medication.
- Always seek medical treatment if you notice signs of
too much lithium in the blood.
- Always tell each health professional
who treats you that you are taking lithium carbonate. Taking certain
medications can interfere with the amount of lithium in your blood. Some
medications can cause your lithium blood level to get too high and other
medications can cause it to get too low.
