What Happens If You Take Lexapro at Night Instead of Morning?

Taking Lexapro at night instead of morning can help reduce daytime drowsiness and improve sleep quality for some patients. Studies show approximately 25-30% of people experience sedation from SSRIs like Lexapro, making evening dosing beneficial for these individuals. The medication's 27-32 hour half-life means switching timing won't affect therapeutic levels, as it takes 4-6 weeks to reach steady state regardless of when you take it. Some patients report better sleep when taking it at bedtime, while others find it causes insomnia. If you experience daytime fatigue or drowsiness with morning doses, switching to nighttime can be effective. Always consult your healthcare provider before changing your dosing schedule to ensure it aligns with your specific needs.
