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 citalopram
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.
Citalopram is available only with your doctor's prescription.
Before Using citalopram
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 citalopram, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to citalopram 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. For non-prescription products, read the label or package ingredients carefully.
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.
|All Trimesters||C||Animal studies have shown an adverse effect and there are no adequate studies in pregnant women OR no animal studies have been conducted and there are no adequate studies in pregnant women.|
Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using citalopram.

Proper Use of citalopram
Take citalopram only as directed by your doctor, to benefit your condition as much as possible. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered.
Citalopram should come with a Medication Guide. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
Citalopram may be taken with or without food. If your doctor tells you to take it at a specific time, follow your doctor's instructions.
If you are using the oral liquid, shake the bottle well before measuring each dose. Use a marked measuring spoon, oral syringe or medicine cup to measure each dose. The average household teaspoon may not hold the right amount of liquid.
You may have to take citalopram for a month or longer before you begin to feel better.
The dose of citalopram will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of citalopram. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
- For oral dosage forms (solution or tablets):
- For depression:
- Adults—At first, 20 milligrams (mg) once a day, taken either in the morning or evening. Your doctor may adjust your dose as needed. However, the dose is usually not more than 40 mg per day.
- Older adults—20 mg once a day, taken either in the morning or evening.
- Children—Use and dose must be determined by your doctor.
- For depression:
If you miss a dose of citalopram, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Ask your healthcare professional how you should dispose of any medicine you do not use.
Precautions While Using citalopram
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 citalopram. 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 citalopram 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.
Citalopram 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®).
Citalopram 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 citalopram.
Citalopram 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 citalopram 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 citalopram 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.
