Drug Class and Mechanism of Action
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 significantly improve mood.
Should you miss a dose of Citalopram, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Citalopram should be stored at the room temperature and kept away from moisture and sunlight. Keep out of reach of children.

- you have known allergic reaction 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;
