What is citalopram, and what is it used for?
Citalopram is an antidepressant in the selective serotonin reuptake inhibitor (SSRI) class. It is prescribed to treat depression and is also used in some patients for anxiety-related conditions, depending on local prescribing guidance.
How does citalopram work?
Citalopram works by blocking the reuptake of serotonin in the brain. This increases serotonin signaling, which is associated with improvements in mood and anxiety symptoms over time.
How long does citalopram take to work?
People typically start noticing effects after the first 1 to 2 weeks, but meaningful symptom improvement often takes several weeks of consistent use.
What are common side effects patients report?
Common side effects can include nausea, headache, sleep changes (insomnia or sleepiness), dry mouth, increased sweating, and sexual side effects. Many side effects lessen after the first couple of weeks.
What are the important safety concerns to know?
Citalopram has important prescribing cautions related to heart rhythm. It can affect the heart’s electrical activity (QT interval), which may increase the risk of abnormal rhythms in susceptible people, particularly at higher doses or when combined with other QT-prolonging drugs.
Can citalopram be stopped suddenly?
Stopping abruptly can cause withdrawal-like symptoms such as dizziness, irritability, anxiety, nausea, and flu-like feelings. Clinicians generally recommend tapering the dose when discontinuing.
What drug interactions matter most?
As with other SSRIs, citalopram can interact with medications that also affect serotonin (raising the risk of serotonin syndrome) and with drugs that affect heart rhythm (raising QT risk). Patients should tell their prescriber about all medicines, supplements, and over-the-counter products.
Is citalopram available as a generic, and what about patents?
Citalopram is widely available as a generic medication. Patent and exclusivity details vary by country and specific formulation, but generic availability usually means the brand’s core exclusivity has ended.

How do clinicians decide on the dose?
Dosing depends on factors such as the patient’s age, liver function, other medications, and risk for QT prolongation. Prescribers may choose lower starting doses and adjust gradually.
