What Medications Are Used to Treat Bipolar Disorder?

In most cases of bipolar disorder, medication is used to help keep someone stable. Medications that are prescribed may be used to treat psychosis, depression, hypomania, or mania present in someone who has bipolar disorder. 

While lithium was once the only medication used for bipolar disorder, many medications are now used to manage the illness. These medications fall under the following categories: anticonvulsants, antidepressants, antipsychotics, and benzodiazepines.

Keep reading to learn more about some of the most common medications used to treat bipolar disorder as well as some other non-pharmacological treatments.

Bipolar Disorder Treatments

Typically, treatment for bipolar disorder includes medication in addition to psychotherapy. Sometimes more than one medication may be recommended to manage symptoms.

For example, a benzodiazepine may be added to a mood stabilizer to treat symptoms of anxiety or sleep disturbances that may occur in bipolar disorder.

Psychotherapy to Treat Bipolar Disorder

Psychotherapy is often used in conjunction with medication to help people with bipolar disorder manage their condition long-term and prevent new episodes. Some modalities that are commonly used in people with bipolar disorder include:

• Psychoeducation (individual or group)
• Cognitive-behavioral therapy
• Family-focused therapy
• Interpersonal and social rhythm therapy
• Group mindfulness-based cognitive therapy
• Integrated group therapy
• Dialectical behavioral therapy

Other treatments may include dark therapy, electroconvulsive therapy, and transcranial magnetic stimulation. Ketamine is a promising treatment option for bipolar disorder. However, it is not FDA-approved for the treatment of bipolar disorder, and more research is needed.

Medications to Treat Bipolar Disorder

Lithium continues to be one of the mainstays of bipolar disorder treatment. However, other options include anticonvulsants, antidepressants, antipsychotics, or benzodiazepines.

Here's what you need to know about these types of medications.

Lithium

Lithium is a naturally occurring mineral. It was not until 1949 that an Australian psychiatrist named John Cade discovered that it was found to help treat manic episodes. However, it was not until 1970 that the U.S. Food and Drug Administration (FDA) approved lithium as a medication to treat bipolar disorder.

• Lithium is thought to act as a mood stabilizer,which reduces mood swings.
• It may also help with decreasing suicide risk.
• It has been studied to be particularly helpful in elderly people dealing with mania.
• It may even help treat unipolar depression (depression without mania).

Anticonvulsant Bipolar Medications

Anticonvulsant medications, also known as antiepileptics, are usually designed to treat seizures associated with epilepsy. However, these medications can also be used to treat bipolar disorder.

The reason that these medications are effective in bipolar disorder is not completely clear:

• One theory suggests that anticonvulsant medications make nerve cells in the brain less excitable, thus leading to a lower likelihood of mania or depression.
• Another theory proposes that they raise the levels of the neurotransmitter GABA,which calms the brain.
• They may also modulate glutamate. Glutamate is an excitatory neurotransmitter, meaning it causes other neurons to fire. Elevated levels of glutamate are often found when someone is experiencing mania.

However, not all anticonvulsants help the same symptoms. For example, Depakote (divalproex sodium) and Tegretol (carbamazepine) tend to work particularly well on mania; Lamictal (lamotrigine) is particularly successful in targeting depression.

Other common anticonvulsants sometimes used for bipolar disorder include:

• Neurontin (gabapentin)
• Topamax (topiramate)
• Gabitril (tiagabine)
• Trileptil (oxcarbazepine)

Antidepressant Bipolar Medications

Prescribing antidepressants for bipolar disorder can be controversial. Some believe they are helpful, while others think they may worsen it, triggering mania and increasing mood cycling.

And some antidepressant classes, such as tricyclics or serotonin-norepinephrine reuptake inhibitors (SNRIs), may cause a higher “switch” rate (from depression to mania) than selective serotonin reuptake inhibitors (SSRIs) and bupropion.

SSRIs include:

• Celexa (citalopram)
• Lexapro (escitalopram)
• Prozac (fluoxetine)
• Luvox (fluvoxamine)
• Paxil (paroxetine)
• Zoloft (sertraline)
• Viibryd (vilazodone)
• Trintellix (vortioxetine)

Antipsychotic Bipolar Medications

Antipsychotic medications are often prescribed for those with bipolar disorder, especially Bipolar I, where delusions and hallucinations are present. Antipsychotic medications can help manage psychotic symptoms associated with bipolar illness, and the newer "atypical" antipsychotics have mood-stabilizing properties.

These medicines come in two classes: newer ones called "atypical" antipsychotics, and older ones called "typical" antipsychotics. Generally, the atypical antipsychotics have a different side effect profile than the older antipsychotics.

However, older antipsychotics are often associated with extrapyramidal symptoms, otherwise known as movement-related side effects, such as acute dystonic reactions, parkinsonism, akinesia, and akathisia. They also have a greater risk of tardive dyskinesia and neuroleptic malignant syndrome.

However, the atypical antipsychotics aren’t perfect either. These agents may carry a higher risk of metabolic side effects such as weight gain and type 2 diabetes.

Seroquel (quetiapine), Latuda (lurasidone), Vraylar (cariprazine), and Zyprexa (olanzapine) are the atypical antipsychotics that have an indication for depression in bipolar disorder.

Benzodiazepines for Bipolar Disorder

Benzodiazepines, anti-anxiety medications, are sometimes prescribed for people with bipolar disorder to treat agitation, anxiety, and sleep disturbances associated with acute mania or bipolar depression.

There is some risk of dependence and abuse with these medications, so they tend to be used for the short-term management of the disorder.

Your doctor can help you safely make any changes to your medication routine, including gradually tapering your dose or switching to a different medication.

Takeaways

Bipolar disorder is generally treated with medications that help stabilize mood and prevent a relapse of symptoms. Lithium has long been the mainstay, but other medications are also effective. In some cases, your doctor may prescribe more than one type of medication to help manage your condition. They may also recommend psychotherapy.

No matter what type of medication your doctor recommends, be sure the adhere to their treatment guidelines. Take your medication as prescribed and let your doctor know about any other medications, supplements, or substances you are currently taking to avoid risky drug interactions.
