Scott Alexander investigates the optimal dosage of Lexapro, comparing it to other antidepressants and exploring the reasons behind its effectiveness at lower doses. Longer summary

Scott Alexander explores the question of the right dose for Lexapro (escitalopram), an antidepressant. He examines official recommendations, compares Lexapro to other SSRIs, and investigates why Lexapro might be effective at lower doses. The post delves into studies on antidepressant dosing, the unique properties of Lexapro, and the potential benefits and risks of higher doses. Scott concludes that while there's no strong evidence for high doses of any antidepressant being more effective, prescribing higher doses of Lexapro might be as safe as other SSRIs and potentially more beneficial in some cases.
