Celexa (citalopram) is an antidepressant in a group of drugs called selective serotonin reuptake inhibitors (SSRIs). Citalopram affects chemicals in the brain that may become unbalanced and cause depression.
Celexa is used to treat depression.
Celexa may also be used for purposes not listed in this medication guide.
You should not take Celexa if you are allergic to citalopram, or if you have a history of Long QT syndrome. Do not use Celexa if you are using an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate). A dangerous drug interaction could occur, leading to serious side effects.
To make sure you can safely take Celexa, tell your doctor if you have any of these other conditions:
- liver or kidney disease;
- heart disease, congestive heart failure, a heart rhythm disorder, or a family history of Long QT syndrome;
- an electrolyte imbalance (such as low levels of potassium or magnesium in your blood);
- seizures or epilepsy;
- bipolar disorder (manic depression); or
- a history of drug abuse or suicidal thoughts.
Get emergency medical help if you have any of these signs of an allergic reaction to Celexa: skin rash or hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Report any new or worsening symptoms to your doctor, such as: mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself.
