What Is Citalopram 20mg?

Citalopram is a prescription antidepressant in the SSRI class, sold under the brand name Celexa. It is FDA-approved to treat major depressive disorder in adults and works by helping restore the balance of serotonin, a natural chemical messenger in the brain. Citalopram is closely related to escitalopram (Lexapro), which is the active form of the same molecule. It is taken as a once-daily tablet, and it may take several weeks of consistent use before the full benefit is felt.

Frequently Asked Questions

What is citalopram used for?

Citalopram is FDA-approved to treat major depressive disorder in adults. Prescribers sometimes use it off-label for anxiety-related conditions. Your provider will determine whether it is appropriate for you.

Is citalopram the same as escitalopram?

No, but they are closely related. Escitalopram (Lexapro) is the purified active form of citalopram (Celexa), and both are SSRIs used to treat depression. They differ in approved uses, dosing, and how individuals respond, so do not substitute one for the other without talking to your provider.

Do I need a prescription for citalopram?

Yes. Citalopram is a prescription-only medication in the United States. A licensed provider must review your health information and issue a valid prescription before it can be dispensed.

How does ordering and shipping work?

After you submit your prescription or complete a provider review, a pharmacist verifies the order at our licensed U.S. pharmacy. Once approved, your medication is shipped directly to your address in discreet packaging.

How long does citalopram take to work?

Some people notice improvements in sleep, energy, or appetite within 1 to 2 weeks, but the full antidepressant effect often takes 4 to 6 weeks. Keep taking it as prescribed even if you feel better, and contact your provider before making any changes.

What is the maximum dose of citalopram?

The maximum recommended dose is 40 mg once daily due to the risk of QT prolongation at higher doses. Patients over 60, those with liver impairment, and CYP2C19 poor metabolizers should not exceed 20 mg daily. Always follow your prescriber's instructions.
