Celexa is an antidepressant in a group of drugs called selective serotonin reuptake inhibitors (SSRIs). It works by restoring the balance of serotonin, a natural occuring substance found in the brain, which helps to improve certain mood problems.
Celexa is used to treat depression.
Celexa may also be used for purposes other than those listed in this medication guide.

Do not take Celexa together with a monoamine oxidase inhibitor (MAOI) such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate). You must wait at least 14 days after stopping an MAOI before you can take Celexa. After you stop taking Celexa, you must wait at least 14 days before you start taking an MAOI.

You may have thoughts about suicide when you first start taking an antidepressant, especially if you are younger than 24 years old. Your doctor will need to check you at regular visits for at least the first 12 weeks of treatment with Celexa.

Call your doctor at once if you have any new or worsening symptoms 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.

However, you may have a relapse of depression if you stop taking your antidepressant during pregnancy. If you are planning a pregnancy, or if you become pregnant while taking Celexa, do not stop taking the medication without first talking to your doctor.
