If you or someone you love has been diagnosed with bipolar disorder, or has experienced intense mood swings that disrupt daily life, you’ve likely heard the term “mood stabilizers” come up in conversations with a doctor. But what exactly are mood stabilizers, how do they work, and who actually needs them?
This guide breaks down everything you need to know about mood stabilizers — from how they work in the brain, to a full mood stabilizer medications list, to a closer look at lithium for bipolar disorder, one of the oldest and most studied treatments in psychiatry. Whether you’re newly diagnosed, supporting a family member, or simply researching treatment options, this article will help you understand where mood stabilizers fit into modern mental health care.
What Are Mood Stabilizers?
Mood stabilizers are a class of psychiatric medications used to even out extreme shifts in mood — most commonly the manic highs and depressive lows associated with bipolar disorder. Unlike antidepressants, which primarily target low mood, mood stabilizers are designed to prevent both ends of the mood spectrum from spiraling out of control.
The term “mood stabilizers” doesn’t refer to a single chemical class the way SSRIs or benzodiazepines do. Instead, it’s a functional category that includes several different types of medications — lithium, certain anticonvulsants, and some atypical antipsychotics — that share a common goal: keeping mood within a manageable, stable range.
For many people living with bipolar disorder, mood stabilizers are the foundation of long-term treatment, often used alongside therapy, lifestyle adjustments, and regular psychiatric follow-up.
How Do Mood Stabilizers Work?
The exact mechanisms behind mood stabilizers vary depending on the specific medication, but in general, they work by calming overactive neural pathways in the brain that are believed to drive manic episodes, while also providing enough support to prevent depressive episodes.
Some mood stabilizers, like lithium, appear to influence neurotransmitter signaling and intracellular pathways involved in mood regulation, though researchers still don’t fully understand every detail of how it works. Others, like anticonvulsant mood stabilizers, were originally developed to treat seizure disorders and were later found to have a calming, mood-leveling effect on the brain — which is why they crossed over into psychiatric use.
Because mood stabilizers work in different ways, your psychiatrist may need to try more than one before finding the medication (or combination of medications) that works best for your specific symptoms.
Who Needs Mood Stabilizers?
Mood stabilizers are most commonly prescribed for:
- Bipolar I disorder — characterized by full manic episodes, often with depressive episodes as well
- Bipolar II disorder — characterized by hypomanic episodes and more prominent depressive episodes
- Cyclothymic disorder — a milder but chronic pattern of mood swings
- Schizoaffective disorder — in some cases, when mood symptoms are a major component
- Severe mood instability — in certain cases where other diagnoses involve significant mood dysregulation
It’s worth noting that mood stabilizers are generally not the first choice for standard (unipolar) depression or anxiety disorders. In fact, giving an antidepressant alone to someone with undiagnosed bipolar disorder can sometimes trigger a manic episode — which is one reason an accurate diagnosis from a psychiatrist is so important before starting any medication plan involving mood stabilizers.
Mood Stabilizer Medications List
One of the most common questions patients ask is simply: what are my options? Below is a general mood stabilizer medications list, organized by category. This list is for educational purposes only — your psychiatrist will determine which option, if any, is appropriate for your specific diagnosis and health history.
Lithium
Lithium carbonate is the original mood stabilizer and remains one of the most effective treatments for bipolar disorder, particularly for reducing manic episodes and lowering the risk of suicide in people with bipolar disorder.
Anticonvulsant Mood Stabilizers
Several medications originally developed to treat epilepsy are also widely used as mood stabilizers, including:
- Valproate (Depakote)
- Lamotrigine (Lamictal)
- Carbamazepine (Tegretol)
- Oxcarbazepine (Trileptal), used off-label in some cases
Each of these has a different side effect profile and is used for different phases of bipolar disorder. Lamotrigine, for example, is often favored for preventing depressive episodes, while valproate is more commonly used for acute mania.
Atypical Antipsychotics Used as Mood Stabilizers
Certain atypical (second-generation) antipsychotics are also used as mood stabilizers, either alone or in combination with lithium or an anticonvulsant, including:
- Quetiapine (Seroquel)
- Olanzapine (Zyprexa)
- Aripiprazole (Abilify)
- Risperidone (Risperdal)
- Lurasidone (Latuda)
These medications can be especially helpful for managing acute manic or mixed episodes, and several are also FDA-approved for bipolar depression.
This mood stabilizer medications list isn’t exhaustive, and new formulations are approved periodically. The right choice depends on your symptom pattern (manic-dominant vs. depressive-dominant), medical history, other medications you’re taking, and how your body responds to treatment over time.
Lithium for Bipolar Disorder
Because lithium for bipolar disorder has been used in psychiatry for decades, it’s worth a closer look. Lithium remains one of the most well-studied mood stabilizers available, with strong evidence supporting its ability to reduce manic episodes, decrease the frequency of mood episodes overall, and lower the risk of suicide — a benefit that sets it apart from many other psychiatric medications.
That said, lithium for bipolar disorder requires careful monitoring. Because lithium has a relatively narrow therapeutic window (meaning the difference between an effective dose and a potentially toxic one is small), patients taking it need regular blood tests to monitor lithium levels, as well as periodic checks of kidney and thyroid function, since lithium can affect both over time.
Common side effects of lithium can include increased thirst, frequent urination, hand tremor, weight gain, and mild cognitive fogginess, though many patients tolerate it well once the right dose is established. Despite the need for monitoring, many psychiatrists still consider lithium for bipolar disorder one of the gold-standard treatments, particularly for classic bipolar I disorder with distinct manic episodes.
Mood Stabilizers vs. Antidepressants
A common point of confusion is the difference between mood stabilizers and antidepressants. While both are used to treat mood-related conditions, they serve different purposes:
- Antidepressants primarily target depressive symptoms by adjusting neurotransmitters like serotonin, norepinephrine, or dopamine.
- Mood stabilizers target the full range of mood instability, including manic, hypomanic, and depressive episodes, with the goal of keeping mood within a stable range over time.
For someone with bipolar disorder, taking an antidepressant without a mood stabilizer can sometimes destabilize mood further or trigger mania. This is why an accurate diagnosis matters so much — treatment that works well for unipolar depression isn’t always appropriate for bipolar disorder, and vice versa.
Side Effects and Monitoring
Because mood stabilizers vary so widely in their mechanisms, their side effects vary too. Some general patterns to be aware of:
- Lithium requires regular blood level monitoring and periodic kidney/thyroid testing.
- Anticonvulsant mood stabilizers like valproate may require liver function monitoring and carry specific risks during pregnancy.
- Antipsychotic mood stabilizers can carry a risk of weight gain, metabolic changes, and (rarely) movement-related side effects, so metabolic monitoring is often recommended.
This is part of why mood stabilizers are typically managed closely by a psychiatrist rather than adjusted independently — ongoing monitoring helps catch side effects early and ensures the medication is working as intended.
How Long Do You Need to Take Mood Stabilizers?
For many people with bipolar disorder, mood stabilizers are a long-term, often lifelong, part of treatment. Bipolar disorder is a chronic condition, and stopping mood stabilizers — even after a long period of stability — carries a significant risk of relapse. Research has consistently shown that maintenance treatment with mood stabilizers substantially reduces the risk of future manic and depressive episodes compared to stopping medication after symptoms improve.
That doesn’t mean the dose or combination of mood stabilizers stays the same forever. Over time, your psychiatrist may adjust your treatment plan based on how your symptoms evolve, side effects you experience, or major life changes like pregnancy planning. Any changes to a mood stabilizer regimen should always be made gradually and under medical supervision, since stopping these medications abruptly can increase the risk of a mood episode.
Finding the Right Mood Stabilizer With a Psychiatrist
Because there’s no single mood stabilizer that works best for everyone, finding the right medication often takes some trial and adjustment. A psychiatrist will typically consider:
- Whether your symptoms are manic-dominant or depressive-dominant
- Your personal and family medical history
- Other medications you’re currently taking
- Your tolerance for specific side effects
- Lifestyle factors like pregnancy planning, kidney or liver health, and monitoring access
This is where working with an experienced, board-certified psychiatrist makes a meaningful difference.

Frequently Asked Questions About Mood Stabilizers
What is the most commonly prescribed mood stabilizer?
Lithium remains one of the most widely used and well-studied mood stabilizers, particularly for bipolar disorder. Other medications, including lamotrigine, valproate, and certain atypical antipsychotics, may also be prescribed depending on the patient’s symptoms and treatment needs.
Can mood stabilizers be used for conditions other than bipolar disorder?
Yes. Some mood stabilizers may be prescribed off-label for conditions such as borderline personality disorder, schizoaffective disorder, or severe mood dysregulation. The choice of medication depends on an individual’s symptoms, medical history, and psychiatric evaluation.
Is lithium for bipolar disorder still used today?
Absolutely. Lithium remains an important treatment option for bipolar disorder because of its strong evidence base in managing mood episodes and reducing suicide risk. However, it requires regular blood tests to monitor lithium levels, kidney function, and thyroid function.
Do mood stabilizers cause weight gain?
Some mood stabilizers, particularly valproate and certain atypical antipsychotics, may cause weight gain. Lamotrigine is generally considered more weight-neutral. A psychiatrist can help select a medication based on treatment goals, potential side effects, and overall health.
How is the right mood stabilizer chosen?
A psychiatrist considers the patient’s symptoms, diagnosis, medical history, other medications, and previous treatment responses. The medication and dosage may be adjusted over time to achieve the best possible balance between symptom control and side effects.
How long does it take for mood stabilizers to work?
The time required depends on the medication and the condition being treated. Some medications may begin improving symptoms within days or weeks, while others require several weeks or longer to show their full benefits. Patients should follow their prescribed treatment plan and consult their psychiatrist if symptoms persist.
Are mood stabilizers safe for long-term use?
Many mood stabilizers can be used safely over the long term when prescribed and monitored by a qualified healthcare professional. Depending on the medication, regular blood tests and monitoring of kidney function, liver function, thyroid function, or weight may be necessary.
Can you stop taking mood stabilizers once you feel better?
No. You should not stop taking mood stabilizers or change your dosage without consulting your psychiatrist, even if you feel better. Stopping suddenly may trigger a relapse or withdrawal-related problems. If discontinuation is appropriate, your doctor can develop a gradual and supervised plan.
