Celexa (citalopram) is an antidepressant approved to treat depression and anxiety in adults. Celexa is a brand-name medication, and it contains the generic drug citalopram. Celexa is also used off-label to treat similar symptoms in conditions like obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD). People will likely experience mild symptoms such as vomiting and nausea to start, but there are still chances for more severe health risks.
What is Celexa & How Is it Used?
Celexa is an antidepressant used to treat depression.1 Celexa is the brand name of citalopram. Celexa is taken as a tablet by mouth once per day. The generic medication, citalopram, also comes as a capsule and as a solution. Celexa belongs to the antidepressant drug class known as selective serotonin reuptake inhibitors (SSRIs). SSRIs work by increasing the amount of serotonin in your brain.2 However, side effects are still possible as the body adjusts to the medication.
Since Celexa is not suitable for everyone, your doctor may recommend other alternatives to treat depression, especially if the condition is persistent or severe. Taking Celexa as directed by your doctor to avoid its adverse health side effects is crucial.
Celexa is FDA-approved for use with disorders such as:3
- Major Depressive Disorder in adults
Celexa is an off-label (non-FDA approved) medication for disorders such as:3
- General Anxiety Disorder (Celexa for anxiety)
- Obsessive-Compulsive Disorder
- Eating Disorders
- Panic Disorder
- Premenstrual Dysphoric Disorder
- Social Anxiety Disorder
- Post-Traumatic Stress Disorder
Celexa changes how the brain reabsorbs the neurotransmitter serotonin, making it more available for use by preventing the reuptake process, which usually reduces availability. This physiological process increases the feeling of improved well-being that all antidepressants aim to make you feel.
Some people may respond differently to Celexa compared to other antidepressants. Celexa is an SSRI. The significant difference between SNRIs and SSRIs is that SSRIs block serotonin reuptake where as SNRIs inhibit both serotonin and norepinephrine reuptake.4
