Description
Lithium is used to treat mania that is part of bipolar disorder (manic-depressive illness). It is also used on a daily basis to reduce the frequency and severity of manic episodes. Manic-depressive patients experience severe mood changes, ranging from an excited or manic state (eg, unusual anger or irritability or a false sense of well-being) to depression or sadness.
It is not known how lithium works to stabilize a person's mood. However, it does act on the central nervous system. It helps you to have more control over your emotions and helps you cope better with the problems of living.
It is important that you and your family understand all the effects of this medicine. These effects depend on your individual condition and response and the amount of lithium you use. You must also know when to contact your doctor if there are problems with using the medicine.
This medicine is available only with your doctor's prescription.
