How to manage bipolar disorder if planning a pregnancy?

Question

Hi doctor,

My 29-year-old daughter has been struggling with bipolar depression for three years, and we cannot seem to find the right medication combination. She was diagnosed after a manic episode and did not sleep for five days straight. The Lithium helps with mania, but makes her feel like a zombie, and she gained 30 pounds. When she tried to lower the dose, she ended up in deep depression for two months and could not get out of bed. Her lithium level is 0.8, which the doctor says is therapeutic, but she hates the side effects. She tried Lamictal but developed a rash, so I had to stop immediately. The depressive episodes of bipolar disorder are worse than the manic ones because she becomes suicidal and has been hospitalized twice. She is also dealing with irregular periods and thinks the mood stabilizers are affecting her hormones. She wants to have kids someday, but is worried about taking these medications during pregnancy. Are there safer options for treating bipolar depression in women who want to get pregnant? Also, she is concerned because her biological father had bipolar disorder and committed suicide when she was 10.

Thanks.

Hi,

Welcome to icliniq.com.

I can understand your concern.

Managing bipolar depression can be challenging, especially when effective medicines cause difficult side effects. Lithium is one of the most reliable options for preventing mania and reducing suicide risk, but it can cause weight gain, fatigue, and hormonal changes in some people. Lamotrigine is often used for bipolar depression, but since your daughter had a rash, it is no longer suitable.

Other medicines specifically approved for bipolar depression include Lurasidone, Quetiapine, and Cariprazine. These can be used alone or with Lithium and often have a different side-effect profile, sometimes with less weight gain and sedation. They can be considered under close psychiatric supervision.

When it comes to pregnancy, treatment choices require careful planning. Lithium, some antipsychotics, and other mood stabilizers carry varying risks during pregnancy, so decisions are based on balancing those risks with the risks of untreated bipolar disorder. In some cases, certain antipsychotics (such as Lurasidone or Olanzapine) may be considered safer, but this must be individualized and discussed with both her psychiatrist and an obstetrician experienced in high-risk pregnancies. Non-medication approaches, like regular sleep schedules, structured daily routines, therapy (including interpersonal and social rhythm therapy), and strong early-warning systems for mood changes are also important in long-term stability and can help minimize medication doses.

Given her history and family risk, it is important that she has regular follow-up and a crisis plan in place. Planning for pregnancy should ideally involve a preconception consultation so medication changes can be made gradually and safely.

I hope this information will help you.

Thanks.
