From the Guidelines
The best management for adults with ADHD and stable bipolar disorder is a combination of stimulant medication and mood stabilizers, with bupropion as an alternative when stimulants are contraindicated. For most patients, methylphenidate (starting at 10mg daily and titrating up to 40-60mg daily) or amphetamine salts (starting at 5mg daily and titrating up to 20-30mg daily) are effective first-line treatments, but must be used alongside the patient's existing mood stabilizer regimen 1. Close monitoring for mood destabilization is essential during the first 4-8 weeks of treatment, with appointments every 1-2 weeks initially. If the patient shows signs of mania or hypomania, the stimulant should be immediately discontinued. For patients with a history of substance abuse or severe manic episodes, non-stimulant options like bupropion (150mg daily, increasing to 300mg daily after one week) are safer. Atomoxetine can also be considered but carries a higher risk of inducing mania. Psychotherapy, particularly cognitive-behavioral therapy focused on executive functioning and emotional regulation, should complement medication. This combined approach works because stimulants address dopamine dysregulation in ADHD while mood stabilizers prevent the potential mood-elevating effects of stimulants from triggering manic episodes. Regular sleep schedules, stress management techniques, and organizational strategies further optimize outcomes. Key considerations include:
- Careful assessment of the patient's history and current symptoms to determine the best treatment approach
- Close monitoring for potential side effects and mood destabilization
- Collaboration with a specialist if necessary, particularly for patients with complex histories or severe symptoms
- Emphasis on psychotherapy and lifestyle modifications to support overall well-being and symptom management. It's worth noting that the provided study 1 focuses on ADHD in pregnancy and the postpartum period, which is not directly relevant to the management of ADHD in adults with stable bipolar disorder. However, the study 1 provides more general guidance on the management of ADHD and other mental health conditions, which can be applied to this patient population.
From the FDA Drug Label
The effectiveness of atomoxetine in the treatment of ADHD was established in 2 randomized, double-blind, placebo-controlled clinical studies of adult patients, age 18 and older, who met DSM-IV criteria for ADHD.
In 2 identical, 10-week, randomized, double-blind, placebo-controlled acute treatment studies (Study 5, N=280; Study 6, N=256), patients received either atomoxetine or placebo. Atomoxetine was administered as a divided dose in the early morning and late afternoon/early evening and titrated according to clinical response in a range of 60 to 120 mg/day
The best management for Attention Deficit Hyperactivity Disorder (ADHD) in adults with stable Bipolar Disorder is not directly addressed in the provided drug label. However, based on the available information, atomoxetine has been shown to be effective in the treatment of ADHD in adults.
- The medication was administered as a divided dose in the early morning and late afternoon/early evening and titrated according to clinical response in a range of 60 to 120 mg/day.
- The mean final dose of atomoxetine for both studies was approximately 95 mg/day.
- ADHD symptoms were statistically significantly improved on atomoxetine, as measured on the ADHD Symptom score from the CAARS scale 2. However, it is crucial to note that the management of ADHD in adults with stable Bipolar Disorder should be approached with caution, and the decision to use atomoxetine or any other medication should be made under the guidance of a qualified healthcare professional, considering the individual patient's specific needs and circumstances.
From the Research
Management of ADHD in Adults with Stable Bipolar Disorder
The management of Attention Deficit Hyperactivity Disorder (ADHD) in adults with stable Bipolar Disorder (BD) is complex and requires careful consideration of the potential interactions between the two conditions.
- The use of stimulants and atomoxetine (ATX) are effective treatments for ADHD, but their use in adults with comorbid BD has not been extensively studied and may be problematic 3.
- A hierarchical approach is desirable, with mood stabilization preceding the treatment of ADHD symptoms 3, 4.
- ATX may be effective in the treatment of ADHD symptoms in BD patients, with a modestly increased risk of (hypo)manic switches and destabilization of the mood disorder when utilized in association with mood stabilizers 3, 5.
- Stimulants are the most effective medications for ADHD, but their use may be contraindicated in the presence of a comorbid drug abuse or in patients that simulate or exaggerate ADHD symptoms in order to obtain stimulants for diversion or abuse 3.
- Cognitive-behavioral therapy (CBT) may be a useful adjunct to medication in the treatment of ADHD in adults with stable BD, particularly for those with residual symptoms despite medication treatment 6.
Considerations for Treatment
When treating adults with ADHD and comorbid BD, it is essential to:
- Accurately diagnose ADHD, BD, and other comorbid conditions to ensure correct targeting of treatments and improvements in patient outcomes 4.
- Monitor patients closely for (hypo)manic symptoms, particularly when using ATX or stimulants 5.
- Consider the potential for substance abuse and diversion when prescribing stimulants 3.
- Use a staged treatment approach, with mood stabilization preceding the treatment of ADHD symptoms 4.
