|Celexa is used to treat major
depression--a stubbornly low mood that persists nearly
every day for at least 2 weeks and interferes with
everyday living. Symptoms may include loss of interest in
your usual activities, insomnia or excessive sleeping, a
change in weight or appetite, constant fidgeting or a
slowdown in movement, fatigue, feelings of worthlessness
or guilt, difficulty thinking or concentrating, and
repeated thoughts of suicide.
Like the antidepressant medications Paxil, Prozac, and Zoloft, Celexa is thought to work by boosting serotonin levels in the brain. Serotonin, one of the nervous system's primary chemical messengers, is known to elevate mood.
