If you live with bipolar disorder and you’re pregnant, or planning to conceive, you may have heard confusing or frightening things. Some people are told to stop all medication. Others are told the risks are minor and to relax. Neither message is quite right.
Here is the reassuring truth first: many people with bipolar disorder have healthy pregnancies and healthy babies. The pregnancy and the first year after birth do carry real risks, though. Those risks are best managed with early planning, a coordinated care team, and an honest conversation about medication.
This guide covers the evidence, the risks (including postpartum psychosis, which deserves far more attention than it gets), and the practical tools that make a difference.
Can You Have a Healthy Pregnancy with Bipolar Disorder?
Yes. Bipolar disorder affects roughly 1% to 2% of people, and many of them are of childbearing age. Pregnancy doesn’t cause bipolar disorder, and it doesn’t make you a “risky” parent. What matters is how well your mood is supported before, during, and after pregnancy.
Two Factors That Shape Almost Every Decision
When bipolar disorder and pregnancy overlap, two periods deserve particular attention: pregnancy itself and the weeks following birth.
1. Pregnancy Does Not Protect Against Relapse
For years, there was an assumption that pregnancy might shield women from mood episodes. It does not. Relapse can occur during pregnancy, particularly when medication is stopped or changed without appropriate medical guidance.
2. The Postpartum Period Carries the Highest Risk
The weeks following birth can bring the greatest risk of relapse, including depressive episodes, mania, and, in some cases, psychosis. This makes the postpartum period an important part of pregnancy planning, not something to consider only after delivery.
The Key Principle: Balance the Risks
Good care is not about automatically choosing medication or avoiding it altogether. It means weighing the risks of untreated bipolar disorder against the potential risks of treatment, then making that decision collaboratively with a healthcare professional.
Ideally, this conversation begins before conception, giving the person and their care team time to consider medication, relapse prevention, pregnancy, delivery, and postpartum support.
Bipolar Disorder Pregnancy Risks: What Does the Evidence Say?
Pregnancy can bring important considerations for people living with bipolar disorder, from the risk of mood episode recurrence to decisions around medication and ongoing support. Understanding these risks can help shape a safer, more informed care plan throughout pregnancy and after birth.
Risks During Pregnancy
Research links untreated or poorly controlled bipolar disorder in pregnancy with a higher chance of preterm birth, low birth weight and pregnancy complications. Some of this risk comes from factors around the illness (poor sleep, missed antenatal care, smoking, substance use, stress) rather than the diagnosis itself. That’s encouraging, because many of these factors can be supported.
Relapse itself is the biggest concern. In a well-known study (Viguera and colleagues, 2007), around 70% of women who stopped mood stabilisers around conception experienced a recurrence during pregnancy, compared with about 20% of those who continued.
Recurrences were more often depressive, and they happened quickly. Stopping abruptly carries a particularly high risk. An untreated mood episode isn’t only distressing for you. Severe depression or mania can affect sleep, nutrition, decision-making, attendance at appointments, and, in the worst cases, safety.
Risks After Birth
A large meta-analysis (Wesseloo and colleagues, 2016) found that about 37% of women with bipolar disorder had a postpartum mood episode. The rate was around 66 percent without preventive medication and about 23% with it. Prevention works.
Postpartum Psychosis: A Psychiatric Emergency
Postpartum psychosis is rare in the general population (about 1 to 2 in 1,000 births), but for someone with bipolar disorder the risk is much higher, around 1 in 5 in some studies. It rises further, in some studies, to around half, if you’ve had a previous postpartum psychosis or a close family member has.
It usually comes on suddenly, often within the first days to two weeks after birth, though it can appear up to several weeks later.
Warning Signs
- Feeling unusually “high”, euphoric or overly energetic, or moods that swing rapidly
- Not sleeping, and not feeling tired, even when the baby sleeps
- Confusion, disorientation or seeming “not themselves”
- Racing thoughts, or speech that is fast or hard to follow
- Paranoia or suspicion, such as believing people are plotting or the baby is in danger or “special”
- Hearing or seeing things others don’t
- Unusual agitation, restlessness or irritability
What To Do
Postpartum psychosis is a medical emergency. It is treatable, and most women recover fully with prompt care, but it can escalate quickly.
- Call 000 or go to the nearest emergency department immediately.
- Don’t wait for a scheduled appointment, and don’t wait to see if she sleeps it off.
- Don’t leave the mother alone with the baby until she has been assessed.
- Tell the team she has bipolar disorder and recently gave birth.
If you’re in crisis or worried about safety, you can also call Lifeline on 13 11 14. For perinatal-specific support, PANDA’s National Perinatal Mental Health Helpline is 1300 726 306.
Admission to a mother-baby unit (where available) lets mother and baby stay together during treatment.
Ask your care team early about which units are accessible from where you live. Bipolar postnatal depression, baby blues and relapse: telling them apart
Baby Blues | Postnatal Depression | Bipolar Relapse / Postpartum Psychosis | |
When | Days 3 to 10 | Any time in first year | Often first days to weeks |
Duration | Resolves within ~2 weeks | Persists beyond 2 weeks | Persists, may escalate fast |
Signs | Tearful, overwhelmed, sensitive | Low mood, exhaustion, guilt, withdrawal | Elevated or very low mood, no sleep, confusion, paranoia, hallucinations |
Action | Rest, support | See GP or perinatal clinician | Urgent assessment; 000 if psychotic |
A note on bipolar disorder and postnatal depression: they can look identical. In someone with bipolar disorder, depression treated with an antidepressant alone can sometimes trigger a “switch” into mania. If you have bipolar disorder and feel low after birth, tell your clinician about your diagnosis so the right treatment is chosen.
Bipolar Medication During Pregnancy: The Honest Picture
Here is the hardest conversation. BD medication isn’t risk-free, and stopping medication isn’t risk-free either. The aim is the safest overall plan, not zero exposure.
Some Principles:
- Never stop suddenly. Abrupt discontinuation sharply raises relapse risk.
- Plan before conception if you can. Some medications carry higher risks in the first trimester, often before pregnancy is confirmed.
- Use the lowest effective dose of the most suitable medication, with regular monitoring. Choose with a specialist. A perinatal psychiatrist can tailor the plan to your history.
Medication Safety at a Glance
This is a simplified overview, and individual circumstances can vary significantly. Medication decisions during pregnancy or breastfeeding should always be discussed with your prescribing doctor.
For personalised, pregnancy and breastfeeding-specific guidance, confirm your medicines and treatment plan with your prescriber and a mental health professional services provider such as ExpertMinds.
Mood Stabilisers in Pregnancy: What about Antidepressants?
Antidepressants are sometimes used for bipolar depression, but generally alongside a mood stabiliser, because on their own they can provoke mania. Any decision should be made by a psychiatrist familiar with your history.
Bipolar and breastfeeding
Breastfeeding is possible for many women with bipolar disorder, but it needs a plan. Two things are worth balancing:
- Sleep
Protecting sleep is one of the strongest defences against relapse. If breastfeeding through the night threatens your sleep, expressing or using formula for one night feed is a valid, evidence-informed choice.
- Medication
Some medications are compatible with breastfeeding; others need infant monitoring or a different approach.
There’s no single “right” answer. A parent who is well and rested, and a baby who is fed, matter most. Guilt has no place in this decision.
Non-Medication Options: It's not "medication or nothing"
Medication isn’t the only way to deal with BD. These approaches can support treatment or, in some situations, be part of it:
- Sleep protection. This is the most powerful non-drug strategy. Aim for a protected block of roughly 5 to 6 hours of sleep where possible, supported by a partner or family member doing a night feed.
- Electroconvulsive therapy (ECT). ECT is often misunderstood but is considered a safe and effective option in pregnancy for severe depression, mania, psychosis or catatonia, particularly when medication isn’t suitable or the situation is urgent. It’s delivered with anaesthetic and obstetric precautions.
- Bright light therapy. There is some evidence for bipolar depression, but it should be supervised, since inappropriate use can trigger mania.
- Psychological therapy. Psychoeducation, CBT and interpersonal and social rhythm therapy (which focuses on stabilising daily routines and sleep) have evidence in bipolar disorder.
- Omega-3 fatty acids. The evidence for treating bipolar disorder is mixed and modest. Omega-3s may be part of a healthy pregnancy diet, but they aren’t a replacement for mood stabilisers.
- Routine, nutrition, gentle movement and limiting alcohol and other substances. These are simple but genuinely protective.
Bipolar Disorder Pregnancy Planning: A Preconception Checklist
Planning ideally starts 3 to 6 months or more before trying to conceive, though it is never too late to plan at whatever stage you’re at.
- Confirm your diagnosis and history. Review previous episodes, triggers and what has worked.
- Book a preconception review. See your GP and, ideally, a perinatal psychiatrist.
- Review all medications. Don’t stop anything on your own. Ask about alternatives, dose changes and monitoring.
- Discuss contraception until the plan is ready. Roughly half of Australian pregnancies are unplanned, so this matters, especially with valproate or carbamazepine.
- Note that lamotrigine levels can drop with oestrogen-containing contraception, and carbamazepine can reduce hormonal contraceptive effectiveness.
- Take folic acid. Your doctor will advise on the dose. Some medications call for a higher dose.
- Build your care team. GP, obstetrician or midwife, perinatal psychiatrist, psychologist and, later, a paediatrician and lactation consultant.
- Talk with your partner or support people. Share warning signs and agree on a plan.
- Prioritise sleep, routine and alcohol reduction.
- Contact a medication information service such as Mothersafe for up-to-date advice.
- Start your Mental Health Birth Plan.
The Mental Health Birth Plan (Advance Choice Document)
Most people have heard of a birth plan. Far fewer have a mental health birth plan, which is sometimes called an advance choice document or advance statement. It’s a practical, underused tool, written while you’re well, that guides your care if you become unwell.
It Includes:
- Your early warning signs, in your words and in the words of people close to you
- Who to call first, and who has your permission to speak to your care team
- Medication preferences, including what has worked, what hasn’t and what you’d like to avoid
- Sleep and feeding plans, such as who covers night feeds and when
- Preferences for hospital care, including a mother-baby unit if you need admission
- Who will care for your baby if you’re admitted, and how contact will be maintained
- Breastfeeding preferences and how they might change if medication is needed
- Practical needs, like pets, older children, work and finances
The name and legal status of these documents vary between Australian states and territories (for example, advance statements in Victoria and advance care directives elsewhere).
Ask your psychiatrist, midwife or mental health service what applies where you live. Even a simple, well-shared document adds real value: it tells your team what you want, when you may find it hard to say.
For Partners and Family: How You Can Help
Your role matters more than you may realise. A short action list:
1. Learn the early warning signs. Watch for changes in sleep, energy, speech, mood and behaviour. Reduced need for sleep without tiredness is one of the earliest and most important flags.
2. Protect sleep. Give a regular night feed (with expressed milk or formula, as suits the plan) so she can have a protected block of sleep.
3. Come to appointments. Attend antenatal and psychiatric visits where she’s comfortable with it. Help remember plans and questions.
4. Know the emergency plan. Keep the crisis contacts and the birth plan somewhere easy to find. If you see signs of psychosis, call 000. Don’t wait.
5. Share the load. Take on meals, washing and visitors so she can rest.
6. Look after yourself too. Supporting someone through this is demanding. PANDA also supports partners.

FAQs
What does pregnancy look like when you have bipolar disorder?
It may require closer planning and monitoring, including reviewing treatment, watching for mood changes and preparing for the postpartum period.
Is lithium safe during pregnancy?
It carries a small, dose-related increase in the risk of heart defects, but it also protects strongly against relapse. Many people continue it with extra monitoring. It’s an individual decision made with a specialist.
What is the risk of bipolar relapse after birth?
It’s high without prevention (roughly two-thirds in one meta-analysis) and much lower with preventive treatment (roughly one in four).
What are the signs of bipolar relapse postpartum?
Little need for sleep, racing thoughts, unusual energy or irritability, persistent low mood, confusion, paranoia, or hallucinations. Psychosis needs emergency care.
Is bipolar disorder passed to my baby?
Genetics play a role, but most children of a parent with bipolar disorder don’t develop it. A supportive, stable home matters.
Conclusion
Pregnancy with bipolar disorder can involve complex decisions, but having the right support in place can make the process more structured and manageable. Planning ahead with your GP, psychiatrist and perinatal care team can help you understand the potential risks, discuss treatment options and prepare for the postpartum period, when the risk of mood episodes can increase.
