Dangerous Drug Black Box Warning:
Citalopram is an antidepressant medication. Like many antidepressants, this medication works by increasing the amount of serotonin in the brain so that the patient feels more balanced mentally. Citalopram takes 1 to 4 weeks to begin working.
Citalopram changes the chemical balance in your brain; this causes you to become physically dependent on the drug for normal functioning. It’s dangerous to abruptly stop using Citalopram for this reason; you may experience serious health problems such as high blood pressure, heart attack or seizure if you do. In addition, you may develop tolerance to this drug and need a larger dose for the same effect.
Some patients have mood swings as a result of taking this medication and may develop suicidal thoughts or impulses. Young people are more susceptible to this side effect than those over the age of 24.
