Citalopram
Citalopram is a selective serotonin reuptake inhibitor (SSRI) used for major depressive disorder. Benefit develops gradually, while adverse effects can occur earlier. Listed uses include major depressive disorder.
Key points
- Do not stop citalopram suddenly; withdrawal symptoms and return of depression can occur.
- Other serotonergic medicines can increase serotonin-syndrome risk.
- Heart-rhythm risk is higher with QT prolongation, low potassium or magnesium, and certain interacting medicines.
Listings are for comparison only; suitability and supply depend on mental-health assessment, prescription, interaction and pharmacy checks.
How it works
Citalopram increases serotonin signalling by reducing its reuptake. Early agitation, sleep changes or suicidal thinking require attention rather than an independent dose change.
Important safety checks
Review bipolar disorder, suicidal thoughts, seizures, bleeding risk, glaucoma, low sodium, liver or kidney disease, pregnancy and all serotonergic or QT-prolonging medicines. Avoid combining with monoamine oxidase inhibitors.
When to seek urgent care
Seek urgent help for suicidal intent, severe agitation with fever and muscle stiffness, fainting, a seizure, a new irregular heartbeat, severe confusion, facial swelling or breathing difficulty.
