Celexa is a prescription medicine used to treat depression. Celexa is in a class of drugs called selective serotonin reuptake inhibitors (SSRIs). These medications change the levels of chemicals in the brain that affect mood.

Celexa is available in tablet form and is usually taken once a day with or without food. Common side effects of Celexa include nausea, sexual problems, and dry mouth. This medication may cause dizziness. Do not drive, operate machinery, or do other dangerous tasks until you know how Celexa affects you.

Suicidality and Antidepressant Drugs

Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of Celexa or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Celexa is not approved for use in pediatric patients.
