Are there any other precautions or warnings for Apo-Citalopram?

Before you begin taking a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Abnormal heart rhythm: Citalopram may cause an abnormal heart rhythm, especially at higher doses. Your doctor may occasionally monitor your heart rate and rhythm with a test called an electrocardiogram. People with a history of a heart rhythm disturbance called QT prolongation should not take this medication. If you have congestive heart failure, slow heart rhythm, are at risk of low potassium or magnesium levels because of certain illnesses or medications, or you are taking certain medications that can affect the heart rhythm (e.g., amiodarone, sotalol), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Bleeding disorders: Citalopram may increase bruising and cuts may take longer to stop bleeding. If you have a bleeding disorder or a history of bleeding problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Diabetes: Citalopram may lower blood sugar levels (hypoglycemia). If you have diabetes, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Drowsiness/reduced alertness: Citalopram may cause drowsiness for some who take it. Avoid activities that require mental alertness, judgment, and physical coordination (such as driving a car or performing hazardous tasks) until you establish how citalopram affects you.

Fractures: There is some evidence that people taking citalopram or other medications in the same class may be at an increased risk of fractures (broken bones) when they first start to take this medication and after long term use.

Glaucoma: This medication may cause the symptoms of glaucoma (increased pressure in the eye) to become worse. If you have glaucoma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Report any changes in vision to your doctor as soon as possible while you are taking this medication.

Heart disease: Citalopram may cause decreased heart rate for some people, which may make symptoms of heart disease worse. If you have heart disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Kidney function: The effect of citalopram when taken by people with severely decreased kidney function has not been well studied. If you have poor kidney function or severe kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication.

If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.

Mania or hypomania: Citalopram may cause activation of mania or hypomania. If you have a history of mania or bipolar disorder, you should be closely monitored by your doctor while taking this medication.

Seizures: Citalopram may increase the risk of developing seizures, particularly if you have a history of seizures. If you have a seizure disorder or have had seizures in the past, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you develop seizures, contact your doctor or seek medical attention immediately.

Serotonin syndrome: Severe reactions are possible when citalopram is combined with other medications that act on serotonin, such as tricyclic antidepressants and serotonin reuptake inhibitors (medications used to treat depression). These combinations must be avoided. Symptoms of a reaction may include muscle rigidity and spasms, difficulty moving, and changes in mental state including delirium and agitation. Coma and death are possible.

Stopping the medication: Stopping this medication suddenly may lead to side effects. If you are thinking of stopping the medication, check with your doctor first.

Suicidal or agitated behaviour: People taking this medication may feel agitated (restless, anxious, aggressive, emotional, and feeling not like themselves) or they may want to hurt themselves or others. These symptoms may occur within several weeks after people start taking this medication. You should be closely monitored by your doctor for emotional and behavioural changes. If you experience any of these symptoms or notice them in a family member who is taking this medication, contact your doctor immediately.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking citalopram, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using this medication have not been established for children and is not indicated for use in children under the age of 18. There have been reports that using this and similar medications in children under 18 years old may cause behavioural and emotional changes such as suicidal thoughts and behaviour.

Seniors: Because this medication is removed from the body by the kidney and liver, seniors may be at increased risk of side effects if they use this medication. Your doctor may decide to start with a lower dose. If you are over 65, discuss with your doctor whether any special monitoring is required.

Depression Symptom Checker Tool

The Depression Symptom Checker tool can help you learn about depression. Use this tool to create a list of your symptoms and rate how much the symptoms impact your life on a daily basis. The checklist is divided into 6 symptom categories that are associated with depression. You can also learn more about symptoms of depression here.

For each statement choose a number from 0 to 4 that describes the impact on your daily life, where 4 has the highest impact and 0 has no impact:

  • 0 = no impact on daily life/no symptoms
  • 1 = mild impact on daily life
  • 2 = moderate impact on daily life
  • 3 = severe impact on daily life
  • 4 = debilitating impact on daily life

It is important to remember that this is not a “score” but a way to help you communicate how much you feel the symptom impacts your daily life. When you finish you will be able to print out your symptoms and share this information with your doctor. Use the Doctor Discussion Guide to prepare for your doctor’s visit.

Rate how much the following symptoms apply to you.

1. Emotions

Depression can affect anyone at any age, although it most commonly appears between 15 and 45 years of age.

Visit your doctor with these results, when booking your appointment inform your doctor that you may need extra time to discuss these matters. Getting help for your depression can change your life. Don’t wait- depression is an illness that can, and should be treated.

Thoughts about death or suicide are common in depression, and it’s important to take such thoughts seriously. If you feel like giving up or as if you might hurt yourself, get help immediately: call your doctor, go to the emergency room or call 911.
