I would agree with Dr Sawhney and suggest you contact your treating doctor before you change the dosage. Lexapro
is basically a Selective Serotonin Re-uptake Inhibitor (SSRI
). And it is useful in depressive disorder due to it's ability to increase the levels of Serotonin in the brain.
Dreams mostly occur during the Rapid-Eye Movement (REM
) stage of sleep. When you are "not" taking an SSRI, the Serotonin levels go down during the REM sleep. But when you are taking SSRI, the levels increase, leading to a disturbance of the REM sleep and vivid nightmares
. This is a well known effect of SSRIs (including Lexapro). Simply put, Lexapro might be responsible for your symptoms of nightmares and reduced sleep. Feeling tired through the day can be due to not getting enough sleep.
You might consider discussing other options with your doctor.
Hope this helps.
