INDICATIONS

Citalopram is used for treating depression. Citalopram is a selective serotonin reuptake inhibitor (SSRI). It works by restoring the balance of serotonin, a natural substance in the brain, which helps to improve certain mood problems.

This may not be a complete list of all interactions that may occur. Ask your health care provider if Citalopram may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

Important safety information:

• Citalopram may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Citalopram with caution. Do not drive or perform other possible unsafe tasks until you know how you react to it.
• Do not drink alcohol while you are using Citalopram.
• Check with your doctor before you use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Citalopram; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
• One to 4 weeks may pass before your symptoms improve. Do NOT take more than the recommended dose, change your dose, or use Citalopram for longer than prescribed without checking with your doctor.
• Children, teenagers, and young adults who take Citalopram may be at increased risk for suicidal thoughts or actions. Watch all patients who take Citalopram closely. Contact the doctor at once if new, worsened, or sudden symptoms such as depressed mood; anxious, restless, or irritable behavior; panic attacks; or any unusual change in mood or behavior occur. Contact the doctor right away if any signs of suicidal thoughts or actions occur.
• Citalopram and a medicine called escitalopram have the same active ingredient. Do not take Citalopram if you are also taking escitalopram.
• If your doctor tells you to stop taking Citalopram, you will need to wait for several weeks before beginning to take certain other medicines (eg, MAOIs, nefazodone). Ask your doctor when you should start to take your new medicines after you have stopped taking Citalopram.
• Citalopram may rarely cause a prolonged, painful erection. This could happen even when you are not having sex. If this is not treated right away, it could lead to permanent sexual problems such as impotence. Contact your doctor right away if this happens.
• Serotonin syndrome is a possibly fatal syndrome that can be caused by Citalopram. Your risk may be greater if you take Citalopram with certain other medicines (eg, "triptans," MAOIs). Symptoms may include agitation; confusion; hallucinations; coma; fever; fast or irregular heartbeat; tremor; excessive sweating; and nausea, vomiting, or diarrhea. Contact your doctor at once if you have any of these symptoms.
• Neuroleptic malignant syndrome (NMS) is a possibly fatal syndrome that can be caused by Citalopram. Symptoms may include fever; stiff muscles; confusion; abnormal thinking; fast or irregular heartbeat; and sweating. Contact your doctor at once if you have any of these symptoms.
• Use Citalopram with caution in the elderly; they may be more sensitive to its effects, especially low blood sodium levels.
• Caution is advised when using Citalopram in children; they may be more sensitive to its effects, especially increased risk of suicidal thoughts or actions.
• Citalopram should be used with extreme caution in children; safety and effectiveness in children have not been confirmed.
• Citalopram may cause weight changes. Children and teenagers may need regular weight and growth checks while they take Citalopram.
• Pregnancy and breast-feeding: Citalopram may cause harm to the fetus if it is used during the last 3 months of pregnancy. If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Citalopram while you are pregnant. Citalopram is found in breast milk. Do not breastfeed while taking Citalopram.
