about this medication
Citalopram is among the first few SSRI (selective serotonin reuptake inhibitors) antidepressant drugs on the market. The FDA first approved citalopram in 1998. It is sold under the brand name Celexa and primarily prescribed to treat depression.
Citalopram is FDA-approved to treat depression. In clinical trials, citalopram was shown to be effective as an acute treatment as well as over the longer term showing a significantly lower depression relapse rate compared to placebo in those who responded well to short term treatment.
Citalopram is believed to increase levels of a mood-enhancing chemical called serotonin in the brain. Serotonin is one of over 40 messenger chemicals (neurotransmitters) that carry signals between nerve cells in the brain (neurons). Like other SSRIs, citalopram lowers the level of serotonin that your neurons reabsorb, which results in more free serotonin in the brain. For some this can improve symptoms of their condition, such as improved mood or reduced panic attacks.
The most common side effects of citalopram include nausea, sleepiness, weakness, dizziness, feeling anxious, trouble sleeping, sexual problems, sweating, shaking, not feeling hungry, dry mouth, constipation, diarrhea, respiratory infections, and yawning. Citalopram also runs the risk of a heart rhythm abnormality (known as QT prolongation).
