Generic Name: citalopram (sye-TAL-oh-pram) (Oral route)
Antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults in short-term studies with major depressive disorder (MDD) and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared with placebo in adults beyond age 24, and there was a reduction in risk with antidepressants compared with placebo in adults aged 65 or older. This risk must be balanced with the clinical need. Monitor patients closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Not approved for use in pediatric patients .

Uses for Celexa
Citalopram is used to treat depression. It belongs to a group of medicines known as selective serotonin reuptake inhibitors (SSRIs). These medicines are thought to work by increasing the activity of a chemical called serotonin in the brain.
This medicine is available only with your doctor's prescription.
Before using Celexa
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

Appropriate studies have not been performed on the relationship of age to the effects of citalopram in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of citalopram in the elderly. However, elderly patients are more likely to have hyponatremia (low sodium in the blood), which may require caution and an adjustment in the dose for patients receiving citalopram.
Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using this medicine.

Precautions while using Celexa
It is very important that your doctor check your progress at regular visits, to allow for changes in your dose and to help reduce any side effects. Blood tests may be needed to check for unwanted effects.
Do not take citalopram with a monoamine oxidase (MAO) inhibitor (eg, isocarboxazid [Marplan®], linezolid (Zyvox®), methylene blue injection, phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]). Do not start taking citalopram during the 2 weeks after you stop a MAO inhibitor and wait 2 weeks after stopping citalopram before you start taking a MAO inhibitor. If you take them together or do not wait 2 weeks, you may develop confusion, agitation, restlessness, stomach or intestinal symptoms, a sudden high body temperature, an extremely high blood pressure, or severe convulsions.
Do not take pimozide (Orap®) while you are taking this medicine. Using these medicines together can cause very serious heart problems.
Citalopram may cause a serious condition called serotonin syndrome if taken together with some medicines. Do not use citalopram with buspirone (Buspar®), fentanyl (Abstral®, Duragesic®), lithium (Eskalith®, Lithobid®), methylene blue injection, tryptophan, St. John's wort, amphetamines, or some pain or migraine medicines (eg, rizatriptan, sumatriptan, tramadol, Frova®, Imitrex®, Maxalt®, Relpax®, Ultram®, Zomig®). Check with your doctor first before taking any other medicines with citalopram.
Citalopram may cause some teenagers and young adults to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. Some people may have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. If you or your caregiver notice any of these unwanted effects, tell your doctor right away. Let the doctor know if you or anyone in your family has bipolar disorder (manic-depressive) or has tried to commit suicide.
Contact your doctor right away if you have any changes to your heart rhythm. You might feel dizzy or faint, or you might have a fast, pounding, or irregular heartbeat. Make sure your doctor knows if you or anyone in your family has ever had a heart rhythm problem such as QT prolongation or slow heartbeat.
Do not suddenly stop taking this medicine without checking first with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This will decrease the chance of having withdrawal symptoms such as agitation, breathing problems, chest pain, confusion, diarrhea, dizziness or lightheadedness, fast heartbeat, headache, increased sweating, muscle pain, nausea, restlessness, runny nose, trouble in sleeping, trembling or shaking, unusual tiredness or weakness, vision changes, or vomiting.
This medicine may increase your risk for bleeding problems. Make sure your doctor knows if you are also taking other medicines that thin the blood, such as aspirin, nonsteroidal antiinflammatory agents, also called NSAIDs (eg, diclofenac, ibuprofen, naproxen, Advil®, Aleve®, Celebrex®, Voltaren®), or warfarin (Coumadin®, Jantoven®).
This medicine may cause hyponatremia (low sodium in the blood). This is more common in elderly patients, those who are taking diuretic medicines for high blood pressure, or those who have decreased amounts of fluid in the body due to severe diarrhea or vomiting. Check with your doctor right away if you have confusion, headache, memory problems, trouble concentrating, weakness, or feel unsteady when standing.
The use of alcohol is not recommended in patients who are taking this medicine.
This medicine may cause some people to become drowsy, to have trouble thinking, or to have problems with movement. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are not alert or well-coordinated.
Your doctor may want to monitor your child's weight and height, because this medicine may cause decreased appetite and weight loss in children.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
