In controlled studies, overall 3% of the people on Lexapro for depression experienced indigestion (which includes heartburn) as opposed to 1% on placebo. The incidence was 2% at 10 mg dose and 6% at a 20 mg dose. This does not necessarily mean that Lexapro causes heartburn. It could be the combination of medications, concomitant illness, or anxiety.
