Warnings & Precautions
Before taking citalopram:
- tell your doctor and pharmacist if you are allergic to citalopram, escitalopram (Lexapro), any other medications, or any of the ingredients in the citalopram product you are taking. Talk to your pharmacist or check the Medication Guide for a list of the ingredients.
- tell your doctor if you are taking pimozide (Orap) or a monoamine oxidase (MAO) inhibitor such as isocarboxazid (Marplan), linezolid (Zyvox), phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate), or if you have stopped taking an MAO inhibitor within the past 14 days. Your doctor will probably tell you not to take citalopram. If you stop taking citalopram, you should wait at least 14 days before you start to take an MAO inhibitor.
- you should know that citalopram is very similar to another SSRI, escitalopram (Lexapro). You should not take these two medications together.
- tell your doctor and pharmacist what other prescription and nonprescription medications and vitamins you are taking or plan to take. Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many medications may interact with citalopram, so be sure to tell your doctor about all the medications you are taking.
- tell your doctor what nutritional supplements and herbal products you are taking, especially products that contain St. John’s wort or tryptophan.
- tell your doctor if you or anyone in your family has or has ever had long QT syndrome (a rare heart problem that may cause irregular heartbeat, fainting, or sudden death) and if you use or have ever used street drugs or have overused prescription medications. Also tell your doctor if you are older than 60 years of age and if you have or have ever had a slow or irregular heartbeat, high blood pressure; bleeding problems; stroke; low levels of magnesium or potassium in your blood, a heart attack, heart failure (condition in which the heart cannot pump enough blood to other parts of the body) or other heart conditions; seizures; or kidney or liver disease. Also tell your doctor if you are experiencing severe vomiting, diarrhea, or sweating, or if you develop these symptoms at any time during your treatment with citalopram.
- tell your doctor if you are pregnant, especially if you are in the last few months of your pregnancy, or if you plan to become pregnant or are breast-feeding. If you become pregnant while taking citalopram, call your doctor. Citalopram may cause problems in newborns following delivery if it is taken during the last months of pregnancy.
- you should know that citalopram may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
- talk to your doctor about the safe use of alcoholic beverages during your treatment with citalopram. Alcohol can make the side effects of citalopram worse.
- you should know that citalopram may cause angle-closure glaucoma (a condition where the fluid is suddenly blocked and unable to flow out of the eye causing a quick, severe increase in eye pressure which may lead to a loss of vision). Talk to your doctor about having an eye examination before you start taking this medication. If you have nausea, eye pain, changes in vision, such as seeing colored rings around lights, and swelling or redness in or around the eye, call your doctor or get emergency medical treatment right away.
Citalopram Dosage
Citalopram comes as a tablet and a solution (liquid) to take by mouth. It is usually taken once a day, in the morning or in the evening, with or without food. Take citalopram at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take citalopram exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may start you on a low dose of citalopram and gradually increase your dose, not more often than once a week.
It may take 1 to 4 weeks before you notice the full benefit of citalopram. Continue to take citalopram even if you feel well. If you suddenly stop taking citalopram, you may experience withdrawal symptoms such as mood changes, irritability, agitation, dizziness, numbness, tingling or electric shock-like sensations in the hands or feet, anxiety, confusion, headache, tiredness, nausea, sweating, shaking, and difficulty falling asleep or staying asleep. Do not stop taking citalopram without talking to your doctor. Your doctor will probably decrease your dose gradually.
Other
Keep all appointments with your doctor and the laboratory. Your doctor may order certain laboratory tests and electrocardiograms (EKG; a test to monitor your heart rate and rhythm) before you start taking citalopram and during your treatment with this medication.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
