CELEXA vs LEXAPRO
Independent side-by-side comparison.
These are close chemical relatives — escitalopram is the active S-enantiomer of citalopram — and for most people the choice between them is a prescriber's call, not a clear win for either.
The key difference
One difference that matters is written into the labels. Celexa's label carries a warning about dose-dependent QTc prolongation, torsade de pointes and sudden death, and tells prescribers to avoid citalopram in people with congenital long QT syndrome, bradycardia, low potassium or magnesium, recent heart attack or uncompensated heart failure, or who take other QT-prolonging drugs. Lexapro's label has no such warning section. That is a fact about the labels, not proof escitalopram is gentle on the heart.
Both carry the same boxed warning: antidepressants increased suicidal thoughts and behaviors in pediatric and young adult patients, and anyone starting one must be watched closely. Both are contraindicated with MAOIs, including linezolid and intravenous methylene blue, because of SEROTONIN SYNDROME — which both labels say can occur even when the drug is taken alone. Both describe DISCONTINUATION SYNDROME (nausea, dizziness, electric-shock sensations, irritability, insomnia, seizures) and say to taper gradually rather than stop abruptly.
What favours Celexa (citalopram)
It stays a reasonable choice when a prescriber sees no cardiac reason to avoid it — no long QT syndrome, no bradycardia, no electrolyte problem, no other QT-prolonging drug — and when the patient is an adult being treated for depression, which is the only population its label covers.
What favours Lexapro (escitalopram)
Lexapro's label reaches further: it is approved for major depressive disorder in adults and patients 12 and older, and for generalized anxiety disorder in adults and patients 7 and older, while Celexa is approved only for depression in adults and is not approved in children. It also carries no QT-prolongation warning, which is why a prescriber may prefer it when cardiac history, electrolytes or other QT-prolonging medicines are a concern.
Bottom line
They are more alike than the internet pretends. Same drug class, same boxed warning, same MAOI contraindication, same taper-don't-quit advice — and escitalopram is literally one half of citalopram. If someone tells you one is "much better" than the other for depression, ask what they are selling. Two labelled differences stand out: the cardiac (QT) warning on citalopram, and Lexapro's broader approved uses in anxiety and in younger patients. Those are prescriber inputs, not shopping criteria. Which one fits depends on your heart history, your other medicines, what is actually being treated, and — often decisively — which one you have tolerated before. We do not sell either of these drugs and we do not sell coupons for them. We rate them on their FDA recall record, which is why we can tell you these are close cousins and that the choice belongs to your doctor. This page is not a substitute for the FDA label or for medical advice, and never stop an SSRI on your own.
This is not a summary of either drug’s FDA label, and it is not complete. Both labels carry warnings, contraindications and interactions that are not on this page. Read the label for the drug you are actually taking — we link both above — and take the decision to your prescriber.
