Yes, olanzapine is compatible with the treatment of ADHD. However, it is important to take precautions when treating ADHD, especially with stimulants or medications that can increase impulsivity. A thorough medical evaluation of the individual's condition will be necessary before making any changes, with close follow-ups afterwards. Starting this type of treatment during perimenopause should not be a problem. If you have any other questions, feel free to ask.
