Lexapro's Half-life. Lexapro's half-life is 27 to 32 hours. If you took a single dose of 20 mg, within 27 to 32 hours that original dose would be halved to 10 mg, then 27 to 32 hours later to 5 mg, and so on until it is out of your bloodstream. Based on Lexapro's half-life, it would take roughly 4.5 to 5 days for Lexapro to be at undetectable levels in your bloodstream.
