Escitalopram (
Lexapro) - An active isomer of citalopram (Celexa) which both belong to a class of
antidepressants known as Selective
serotonin reuptake inhibitors (
SSRIs).
SSRIs are not likely to cause weight gain if used for 6 months or less.
Opinions vary as to whether they cause weight gain when used for 1 year or longer. Paroxetine (Paxil) may be more likely than other
SSRIs to cause weight gain.[2]
In its revised practice guideline for the treatment of major depressive disorder,[1] the American Psychiatric Association acknowledges that the literature differs as to whether patients taking
SSRIs beyond the acute phase experience weight gain as a medication side effect.[1]
Fighting weight gain once it has occurred can be very difficult, and it is advisable to consider the likelihood and potential consequences of weight gain when choosing an
antidepressant.[2,3]
It has been found that adding low-dose bupropion (Wellbutrin) (100 to 150 mg/day) or topiramate (25 to 50 mg/day) may help weight loss when used in addition to diet control and exercise.[4] In general, bupropion (Wellbutrin) is more likely to cause weight loss.
Please discuss these options with your psychiatrist.
