What Is Citalopram?

Citalopram is an antidepressant medication that affects neurotransmitters, the chemicals that nerves within the brain use to communicate with each other. Neurotransmitters are manufactured and released by nerves and then travel and attach to nearby nerves. Therefore, neurotransmitters can be thought of as the communication system of the brain. Many experts believe that an imbalance among neurotransmitters is the cause of depression. Citalopram works by preventing the uptake of one neurotransmitter, serotonin, by nerve cells after it has been released. Also, citalopram is in the class of drugs called selective serotonin reuptake inhibitors (SSRIs), a class that also contains fluoxetine (Prozac), paroxetine (Paxil) and sertraline (Zoloft).

Citalopram Warnings

The FDA requires citalopram to carry a black-box warning because some children, teenagers, and young adults who took antidepressants such as citalopram during clinical studies had suicidal thoughts and behavior. It is advised that children under 18 shouldn’t take citalopram unless a doctor decides it’s the best option. The FDA also issued a Safety Announcement in 2012 recommending that citalopram not be prescribed at doses greater than 40 milligrams a day because of the increased risk potentially dangerous abnormalities in the electrical activity of the heart.

Children who do take citalopram may be more sensitive to its side effects especially appetite and weight loss. Your doctor will closely monitor both. Citalopram may cause problems in newborns following delivery if it is taken during the last months of pregnancy.
