Citalopram is used for:

Treating depression. It may also be used for other conditions as determined by your doctor.

Citalopram is a selective serotonin reuptake inhibitor (SSRI). It helps to restore the brain's chemical balance by increasing the supply of serotonin, which helps improve mood.

Do NOT use Citalopram if:

• you are allergic to any ingredient in Citalopram
• you are taking or have taken a monoamine oxidase (MAO) inhibitor (eg, phenelzine) or St. John's wort within the last 14 days
• you are taking astemizole, pimozide, dexfenfluramine, fenfluramine, phenothiazines (eg, thioridazine), sibutramine, or terfenadine

Contact your doctor or health care provider right away if any of these apply to you.
