What does escitalopram do and how effective is it?
What does escitalopram do?
Escitalopram is a selective serotonin reuptake inhibitor (SSRI). It is related to the SSRI citalopram. Serotonin is a neurotransmitter — a chemical that relays signals between the cells in your brain. SSRIs increase the amount of serotonin in your brain, and this is how escitalopram is thought to improve the symptoms of depression.
How effective is escitalopram?
About 50% of people treated with antidepressants find their depression symptoms are halved.
Although all antidepressants have shown similar efficacy when tested in groups of people in clinical trials, keep in mind that individuals can find one antidepressant works better for them than another. So if the first antidepressant you try doesn’t seem to be working for you after a few weeks, talk to your doctor about switching to another. A psychological therapy, such as cognitive behavioural therapy (CBT), could also be an option.
