What is Lexapro?
Escitalopram (Lexapro) is a once-daily antidepressant that helps with depression and anxiety over time. It doesn’t work like Xanax—there’s no quick calm-down effect—but over 2 to 6 weeks, many people feel less overwhelmed, less stuck in their head, and more like themselves again. Upsides: simple dosing, usually pretty well tolerated, and widely used. Downsides: nausea or jitteriness during the first week or two, sexual side effects (low libido or delayed orgasm), and withdrawal symptoms if it’s stopped too fast. For younger people (especially under 25), energy can improve before mood fully lifts, which is why we watch closely for any increase in suicidal thoughts at the beginning or when changing the dose.
