How it works
AbilifyAtivan
Abilify (Aripiprazole) is an atypical antipsychotic. Researchers don't know exactly how it works. It seems to change dopamine and serotonin activity in your brain, which affects thoughts and mood.Ativan (Lorazepam) is a fast-acting benzodiazepine. It affects neurotransmitters in the brain and calms the nervous system. This reduces anxiety and can cause sleepiness.
