Both citalopram and escitalopram are antidepressants belonging to the SSRI class. While escitalopram (marketed in the U.S. as Lexapro) contains only the S-stereoisomer (or enantiomer) of the drug citalopram, Celexa or generic citalopram is a racemic mixture of the S-citalopram and its mirror image, R-citalopram, which is less effective as an antidepressant.

Serotonin (5-HT) is one of the neurotransmitters involved in mood regulation and has been implicated in the development of mood and anxiety disorders. Serotonin transporters (SERT) facilitate the transfer of serotonin into neurons; serotonin reuptake inhibitor (SSRI) antidepressants bind to these transporters and appear to exert their effect on mood by inhibiting the reuptake of serotonin and thus increasing the levels of this neurotransmitter at the synapse.
We previously reported that paroxetine, a selective serotonin reuptake inhibitor (SSRI), may affect sperm motility and may thus have a negative impact on male fertility. Many women who are planning a pregnancy question whether SSRIs and other antidepressants may affect fertility; this is obviously a particularly important issue for those who are having difficulty conceiving.
Women face difficult choices when deciding whether or not to continue psychiatric medications during pregnancy. This choice can be especially difficult for women taking newer medications which lack adequate reproductive safety data.
For decades, estrogen has been used to treat menopausal symptoms, including night sweats and hot flashes. However, after studies reported that estrogen increases the risk of cardiovascular disease and breast cancer, many patients and clinicians have looked into alternative treatments for hot flashes, including selective serotonin reuptake inhibitors (SSRIs). According to a new study published in the Journal of the American Medical Association, treatment with the selective serotonin reuptake inhibitor (SSRI) escitalopram (Lexapro) significantly reduces the frequency and severity of menopausal hot flashes compared with placebo.
Many individuals have the experience of weight gain while receiving treatment with an antidepressant, and often wonder if selective serotonin reuptake inhibitors (SSRIs) are associated with weight gain. This is an excellent, complex, and clinically important question.
Increased muscle tone, jitteriness, sleep disturbance, irritability, feeding problems, mild respiratory distress and myoclonus have been reported as symptoms of a potential neonatal distress syndrome related to exposure to SSRIs in late pregnancy. The average duration of symptoms reported is 48 hours. It is estimated that between 25-30% of SSRI-exposed infants are at risk for this syndrome. No treatment intervention is required. Reassuringly, follow-up studies have shown that at 2, 4, 6, and 8 months SSRI-exposed infants are indistinguishable from control infants without known exposure.
