Quick answer
Bipolar II disorder is a pattern of depressive episodes and hypomanic episodes: stretches of unusually high energy that are less severe than full mania. Hypomania can feel good or productive, so it often goes unnoticed, and many people seek help only for depression. Bipolar II is treatable, and getting the diagnosis right matters, because the medication approach is different from depression alone.
Key takeaways
- Bipolar II involves hypomania, a milder high than mania, along with periods of depression.
- It's often first diagnosed as depression, because hypomania can feel like a good stretch.
- Antidepressants aren't used on their own in bipolar disorder, so an accurate diagnosis changes the plan.
- Two medications, quetiapine and lumateperone, are FDA-approved for depressive episodes in bipolar II.
What bipolar II looks like
Bipolar II disorder is a pattern of depressive episodes and hypomania: A milder form of mania: a stretch of unusually high energy, less need for sleep and racing ideas, without the severe disruption of full mania. episodes. Hypomania is like mania but less severe, and it doesn't get in the way of daily life as much. Many people with bipolar II spend long stretches in a low-grade depression, and depression is often what brings them in.
During a hypomanic period
- Much more energy and activity than usual
- Needing less sleep, without feeling tired
- Racing thoughts, or talking more and faster
- Feeling unusually confident or driven
- Taking on lots of things at once
During a depressive period
- Feeling down, empty or hopeless
- Losing interest in almost everything
- Trouble concentrating or making decisions
- Sleeping much more, or much less
- Feeling slowed down, or restless
- Thoughts of death or suicide
These signs are a general guide, not a checklist for diagnosis.
Hypomania can feel very good and productive. You may not feel that anything is wrong, though family and friends may notice the change. A depressive period may follow. Read more: Hypomania: when feeling great is actually a symptom.
If depression ever brings thoughts of suicide, please reach out. If you're in crisis or thinking about harming yourself, call or text 988 (Suicide & Crisis Lifeline), any time, day or night. In an emergency, call 911 or go to the nearest emergency room.
How it's evaluated
Bipolar II can go undiagnosed for years. People often seek help only for depression, and the hypomanic periods go unnoticed. During a low period, bipolar depression can look just like depression, so the clue is in your history. A careful evaluation looks at:
- Any past stretches of unusually high energy, less need for sleep or racing ideas, even if they felt good
- How your moods have shifted over months and years
- Family history of bipolar disorder or other mood conditions
- How you've responded to antidepressants in the past, including any high period after starting one
- Health conditions, such as thyroid disease, and medications or substances that can affect mood
- Conditions that often come along, such as anxiety, ADHD, or alcohol or drug use
With your OK, someone who knows you well can help us see patterns you might not notice yourself. This is part of a comprehensive psychiatric evaluation. Your first evaluation is up to 90 minutes in length. Some people need more time, some less, and we take the time you need. Follow-up visits are typically 20 to 30 minutes, and extended follow-ups are available. If you're wondering about your own pattern, our guide for when your moods swing up and down can help you prepare.
How we help
Getting the diagnosis right changes the plan. Antidepressants aren't used on their own in bipolar disorder, because they can trigger a high or rapid cycling, meaning more frequent mood episodes. Bipolar depression is often treated with a mood stabilizer: A medication that helps prevent mood episodes or make them less severe. or an atypical antipsychotic. If an antidepressant is added, it's alongside one of these.
Some people need to try more than one medication before finding what works. We weigh your past responses, side effects, any lab monitoring, other health conditions, pregnancy plans and your own preferences, and we explain each choice so you understand it.
Visits also include practical work: keeping a mood chart, protecting a regular sleep routine, pacing your energy during good stretches, and spotting early warning signs. Some therapies help alongside medication, such as interpersonal and social rhythm therapy, and cognitive behavioral therapy for sleep problems. We don't offer standalone weekly therapy, but we're happy to help you find a therapist and, with your permission, we'll coordinate with them.
Bipolar disorder usually needs long-term treatment. Regular follow-ups help catch changes early and adjust carefully. Please don't stop a medication on your own; some can cause withdrawal symptoms or a return of symptoms if stopped suddenly.

Medication quick facts
Medications for bipolar II
Two medications are FDA-approved for depressive episodes in bipolar II: quetiapine (Seroquel), approved for depressive episodes in bipolar disorder based on studies that included bipolar I and II, and lumateperone (Caplyta), approved for depression in bipolar I or II, alone or with lithium or valproate. Mood stabilizers and other atypical antipsychotics are also used in bipolar disorder. Your provider will talk with you about which options fit you.

Also commonly used (off-label)
Not FDA-approved for this condition
For bipolar II depression, only quetiapine (Seroquel, Seroquel XR) and lumateperone (Caplyta) are FDA-approved, and no medication is specifically FDA-approved to prevent bipolar II episodes. These are a few of several options used off-label, meaning a medication approved for something else is used because research supports it. Your provider will talk with you about what fits you.

Frequently asked questions
I was diagnosed with depression. Could it be bipolar II?
Sometimes. People with bipolar II often seek help only for depression, and hypomania can go unnoticed. A careful evaluation looks at your full history, including any high periods.
How is hypomania different from just a good mood?
Everyone has good days. Hypomania is a distinct stretch, usually lasting days or longer, of unusually high energy, less need for sleep and racing ideas. It's a clear change from your usual self, and others often notice it.
I take an antidepressant. Should I stop it?
Please don't stop a medication on your own; some can cause withdrawal symptoms or a return of symptoms if stopped suddenly. If bipolar II is a possibility, your provider will review your medications with you and explain any changes.
Can you treat bipolar II by video?
Yes, when outpatient care is safe for you. Most visits are by secure video, anywhere in New Jersey. Our office is in Mount Laurel, NJ, and in-person visits there are limited and by appointment only; ask our office.
Do I need therapy too?
Some types of therapy help alongside medication. Our visits include practical work on sleep, routines and warning signs. We don't offer standalone weekly therapy, but we're happy to help you find a therapist and, with your permission, we'll coordinate with them.
Is a psychiatric nurse practitioner the same as a psychiatrist?
Both diagnose psychiatric conditions and prescribe psychiatric medication. Ours are board-certified psychiatric nurse practitioners (PMHNP-BC), focused on careful evaluation and medication management.

2Why is bipolar II often missed?
People often seek help only for depression, and hypomania goes unnoticed.
3Which two medications are FDA-approved for depressive episodes in bipolar II?
Quetiapine (Seroquel) and lumateperone (Caplyta) are FDA-approved for bipolar II depression.
Myth or fact? Bipolar II disorder
Choose an answer for each to see the explanation. Nothing is saved.
1Bipolar II is just a milder version of bipolar I.
Myth. Its highs are less severe, but many people with bipolar II spend long stretches in depression.
2Feeling great, full of energy and needing little sleep can be a symptom.
Fact. That can be hypomania. It often feels good at the time, which is why it's easy to miss.
3Antidepressants alone are the usual treatment for bipolar II depression.
Myth. Antidepressants aren't used on their own in bipolar disorder, because they can trigger a high or rapid cycling.
