Indications
Lithmax is an oral medication used to treat manic episodes of bipolar disorder. It contains Lithium Carbonate which controls the symptoms of bipolar disorder by regulating neurotransmitters, which are responsible for transmitting signals between nerve cells.
Lithmax increases the availability of a neurotransmitter called serotonin and decreases the activity of another neurotransmitter called dopamine, which is associated with manic episodes. By doing so, Lithmax can help stabilize a person's mood and reduce the symptoms of mania.
Use and Dosage
Lithium Carbonate ER comes in the form of 300 mg extended-release tablet to take once or twice daily with food or as directed by your healthcare provider. The tablet should be swallowed whole and not chewed, crushed, or broken. Drink plenty of fluids and maintain a balanced diet while taking the tablet. Also, keep all medical and laboratory appointments while taking the tablet. Note that the tablets should not be taken by people who are severely debilitated or severely dehydrated or are taking diuretics (water pills).
Lithium Carbonate ER should be taken exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
