Patient discussion about clonazepam

Q. Can clonazepam cause personality changes?

A. Yes, clonazepam can cause personality changes, however it is not one of its most common side effects. More common side effects are drowsiness, irritability and aggression and impaired motor function (coordination, balance) and with higher doses it can cause slight amnesia.

Q. my dad is bipolar II and he was on lithium and clonazepam which had put his mania under control.. hi all…… my dad is bipolar II and he was on lithium and clonazepam which had put his mania under control, but he sleeps a lot, as he finds his sleep refreshing him; which is due to medicine. On stopping the medicines his insomnia like condition starts and so now he takes his doses in excess to sleep…..we were told not to stop on these medicines……is it all right?

A. Over dose of lithium would have serious side effects and especially when the condition demands to have them life long. And if your dad is sleeping a lot, which might be due the intake of clonezepam, which does actually treats insomnia but lithium is used to control his mania. So I feel he can increase on dose of clonezepam, but that too, when his doctor agrees
