Using Medication to Prevent a Bipolar Relapse

Mood stabilizers, especially lithium and divalproex, are the cornerstones of prevention or long-term maintenance treatment. About 1 in 3 people with bipolar disorder will remain completely free of symptoms just by taking mood stabilizing medication for life. Most other people experience a great reduction in the frequency and severity of episodes during maintenance treatment.

It is important not to become overly discouraged when episodes do occur and to recognize that the success of treatment can only be evaluated over the long term, by looking at the frequency and severity of episodes. Be sure to report changes in mood to your doctor immediately, because adjustments in your medicine at the first warning signs can often restore normal mood and head off a full-blown episode. Medication adjustments should be viewed as a routine part of treatment (just as insulin doses are changed from time to time in diabetes). Most patients with bipolar disorder do best on a combination or “cocktail” of medications. Often the best response is achieved with 1 or more mood stabilizers, supplemented from time to time with an antidepressant or possibly an antipsychotic medication.

Continuing to take medication correctly and as prescribed (which is called adherence) on a long-term basis is difficult whether you are being treated for a medical condition (such as high blood pressure or diabetes) or for bipolar disorder. Individuals with bipolar disorder are often tempted to stop taking their medication during maintenance treatment for several reasons. They may feel free of symptoms and think they don’t need medication any more. They may find the side effects too hard to deal with. Or they may miss the mild euphoria they experience during hypomanic episodes. However, research clearly indicates that stopping maintenance medication almost always results in relapse, usually in weeks to months after stopping. In the case of lithium discontinuation, the rate of suicide rises precipitously after discontinuation. There is some evidence that stopping lithium in an abrupt fashion (rather than slowly tapering off) carries a much greater risk of relapse. Therefore, if you must discontinue  medication, it should be done gradually under the close medical supervision of your doctor.

If someone has had only a single episode of mania, consideration may be given to tapering the medication after about a year. However, if the single episode occurs in someone with a strong family history of bipolar disorder or is particularly severe, longer-term maintenance treatment should be considered. If someone has had two or more manic or depressive episodes, experts strongly recommend taking preventive medication indefinitely. The only times to consider stopping a preventive medication that is working well is if a medical condition or severe side effect prevents its safe use, or when a woman is trying to become pregnant. Even these situations may not be absolute reasons to stop, and substitute medications can often be found. You should discuss each of these situations carefully with your doctor.
