Hello!
Thank you for asking on HCM!
I carefully read your question and would explain that this is a complex disorder and its therapy is complex too.
Regarding
lorazepam, it can help regulate sleep and also
anxiety during the day. But it should be used for a short time, in the beginning of therapy, because it can cause addiction and tolerance.
As this disorder is characterized by episodes of
depression and
mania, it is necessary to take antidepressants coupled with anti-psychotic drugs.
From the other hand, anti-epileptic drugs (
valproic acid, carbamazepines) can be used in addition to help maintain a humor stability.
That is why he is taking a lot of drugs: because they act in relieving different symptoms of his medical condition.
Hope to have clarified some of your uncertainties!
Kind regards, Dr. Aida
