I am not familiar
with celexa, but my mom takes it, and it seems to help her.
Ativan is a fast-acting benzodiazepine that will kick in about 20 min. This will keep you calm for about four hours. If you doc prescribed both, then its okay to take both as directed. Ativan, like i said, is a bezo, and all benzos can be addictive. Never, ever take more than doc says. And if your doc wants to take you off of it, you MUST taper, less and less each week until none.
