I am waiting for my lorazepam prescription to be refilled, but I have to work tomorrow. So my question is can I take one 0.5 mg clonazepam with my 40 mg celexa? The last time I took a lorazepam was 7 a.m. Friday morning 05/27/2016 and it was 0.25 mg , and I will not be taking the clonazepam until 7 a.m. tomorrow morning 05/28/2016.
