My son is diagnosed with Bipolar 1 disorder and he also has serious anxiety problem. He has been prescribed to Ativan (take as needed) to treat his anxiety problem for a long time. Recently, his doctor changed his medication regime to Lithium (1500mgs/day) + Latuda (120mg/day) to treat his bipolar symptoms with good results. However, when my son took Ativan as needed from time to time, he could sleep 14 ~ 16 hours straight which doesn't seem right to me. Is it O.K. for my son to continue to take Ativan now he is taking Latuda? If not, what other anti-anxiety drugs are available that can be taken together with Latuda?
