Benzodiazepines rapidly help control certain manic symptoms -- such as restlessness, agitation, or insomnia -- in bipolar disorder until mood-stabilizing drugs can take effect. They are usually taken for a brief time, up to two weeks or so, with other mood-stabilizing drugs.
Cyclothymia -- or cyclothymic disorder -- is a relatively mild mood disorder. In cyclothymic disorder, moods swing between short periods of mild depression and hypomania, an elevated mood. The low and high mood swings never reach the severity of major depression or full mania. People with cyclothymic disorder have milder symptoms than occur in full-blown bipolar disorder.
Benzodiazepines can be habit-forming and addictive. It is also dangerous to combine them with alcohol or certain other medications.
If you have been taking the benzodiazepines in high doses or for a long time, you may suffer withdrawal symptoms if you stop the drug suddenly. Talk with your doctor about whether you still need the medication and, if not, how to taper off the drug.
