Citalopram is used in the treatment of depression, anxiety disorder, panic disorder, obsessive-compulsive disorder, phobias, and post-traumatic stress disorder.
How Citalopram works Citalopram is part of a group of antidepressants known as selective serotonin reuptake inhibitors, or SSRIs. It is believed to work by increasing the levels of the mood-enhancing neurotransmitter serotonin in the brain. This may help improve your energy levels and overall feelings of well-being.
Common side effects of Citalopram include erectile dysfunction, insomnia (difficulty sleeping), low sexual desire, nausea, restlessness, upset stomach, vomiting, and weight gain.
