Citalopram is a medication prescribed to treat depression. It belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs).
Citalopram is used to treat major depressive disorder (MDD), commonly known as depression.
It may also be prescribed for other mental health conditions as determined by your healthcare provider.
Citalopram works by increasing the levels of serotonin, a neurotransmitter in the brain that affects mood, emotions, and behavior. By enhancing serotonin activity, citalopram helps alleviate symptoms of depression and anxiety disorders.
Citalopram is typically taken orally once a day, in the morning or evening, with or without food. Your healthcare provider will determine the appropriate dosage based on your condition and response to treatment.
Consult your healthcare provider for specific instructions on how to take citalopram properly.
The time it takes to notice improvements in your symptoms while taking citalopram can vary. It may take several weeks to months to experience the full benefits of the medication. Continue taking citalopram as prescribed, even if you start feeling better, as abruptly stopping the medication can lead to withdrawal symptoms.
While citalopram is primarily prescribed for depression, healthcare providers may sometimes prescribe it off-label for other conditions.
Some off-label uses of citalopram may include:

If you have any questions about your dosage, contact your healthcare provider. If you want to talk to a provider right away, book an online doctor appointment on Sesame to discuss your concerns.
If you miss a dose, take it as soon as you remember it. If it's almost time for another dose of citalopram, skip the missed dose and take your next dose as scheduled. Do not take or apply a double dose of citalopram.
Even if you begin to feel better, do not stop taking citalopram abruptly without consulting your healthcare provider. Suddenly stopping the medication can cause withdrawal symptoms or a relapse of your condition. Your doctor may need to gradually decrease your dose to avoid these effects.

Keep the medication out of the reach of children and ensure that the container is tightly closed.
