Key takeaways
- Citalopram is an SSRI antidepressant approved for major depressive disorder in adults and sometimes prescribed for other conditions.
- Benefits take time to develop, and gradual clinician-guided dose reduction helps manage discontinuation symptoms.
- Monitoring considers suicidal thoughts, heart rhythm concerns, and interactions that can increase the risk of serotonin syndrome.
Citalopram brand names
\nCitalopram is available as generic citalopram or by the brand name Celexa.\n
What is citalopram prescribed for?Obsessive-compulsive disorder
\nThe U.S. Food and Drug Administration (FDA) approved citalopram for treating major depressive disorder in adults. There are additional risk factors to consider when used in the treatment of depression symptoms in pediatric patients.\nLess commonly, citalopram is used off-label to treat: [3]\n
- \n
- Obsessive-compulsive disorder \n
- Eating disorders \n
- Alcohol use disorder \n
- Anxiety disorders including social anxiety disorder and panic disorder \n
- Post-traumatic stress disorder \n
- Premenstrual dysphoric disorder \n
- Pins and needles sensations in hands and feet due to diabetes complications \n
- Male sexual dysfunction \n
How does citalopram work?
\nCitalopram is a selective serotonin reuptake inhibitor (SSRI). SSRIs like Celexa work in the body by preventing the reuptake of serotonin in the brain, resulting in a higher serotonin level.\n
Experts believe that serotonin - a neurotransmitter - is a \"feel-good\" chemical in the brain that helps regulate multiple bodily functions such as the stress response. Researchers have linked low serotonin levels to depression symptoms in some cases.
\nMedical monitoring of all prescriptions taken in conjunction with citalopram, or other SSRI medications, is critical, as serotonin syndrome can occur if serotonin levels become too high. Serotonin syndrome can be life threatening.\n
How is citalopram usually taken?
\nCitalopram is taken orally in a tablet or liquid solution. This medication is only available by prescription and should be used as prescribed by your doctor or healthcare provider. Never take citalopram without medical advice.\n
Citalopram is usually taken once a day. It is not necessary to take citalopram at a certain time of day; however, it is important to take it consistently at the same time every day.
It is recommended that Celexa be prescribed at a lower initial dose and gradually increased to a therapeutic dose over at least a week. Dosages typically range between 20-40 mg per day[1].
\nLiquid solutions should be measured with the supplied device to ensure the accuracy of the dose[2].\n
How long does citalopram stay in your system?
Citalopram has a relatively long half-life of 35 hours. The body will eliminate most of the medication within seven days of the last dose. However, for some people, it may still be detectable in their system for up to 14 days.
\nCitalopram can take up to four weeks for its benefits to be felt as its level within the body builds to a therapeutic level[3]. It is likely the doctor will gradually lower the daily dosage when discontinuing the use of this medication to avoid withdrawal symptoms.
\nCelexa withdrawal symptoms include: [1]\n- \n
- Nausea \n
- Depressed mood \n
- Irritability/agitation \n
- Dizziness \n
- Paresthesia \n
- Tremors \n
- Anxiety \n
- Headache \n
- Lethargy \n
- Insomnia \n
- Tinnitus \n
- Seizures \n

- Runny nose or nosebleeds \n

\nSSRIs, including Celexa and its generic version, have been known to cause sexual dysfunction such as decreased libido for all genders[1]. It is important to discuss changes in sexual functioning with the doctor to manage these adverse effects and rule out other potential causes.\n
People experiencing severe citalopram side effects should immediately discuss their concerns with the doctor.
Severe citalopram side effects include: [3]\n
- \n

\nSeek emergency medical assistance if any symptoms of an allergic reaction occur. Symptoms of an allergic reaction to citalopram include: [2]\n
- \n
- Hives \n
- Rash \n
- Blisters \n
- Fever \n

Citalopram precautions
\nPreexisting medical conditions need to be discussed with a doctor or healthcare professional before taking citalopram to avoid dangerous adverse reactions.\nCitalopram may not be safe for people who have ever had: [2]\n
- \n
- Heart problems, including irregular heart rhythm \n
- High blood pressure \n
- Stroke \n
- Liver or kidney disease \n
- Glaucoma \n
- Seizures \n
- Bipolar disorder \n
- Low sodium \n
- Bleeding disorders \n
- Long QT syndrome (a heart rhythm disorder) \n
\nCitalopram, and other SSRI medications, can sometimes cause thoughts of suicide. There is an increased risk of suicide thoughts for children and teens[2].\n
Citalopram is linked to mania symptoms in those with bipolar disorder. It is important to discuss any sudden changes in mood or behavior with the doctor while taking citalopram.
Citalopram is not safe for use during pregnancy or while breastfeeding. However, before stopping citalopram due to pregnancy, it is important to speak with the doctor about gradually decreasing the dose[1].
Alcohol used in conjunction with citalopram may cause worsening of its side effects.
\nCitalopram may cause increased drowsiness during the day. Caution should be taken before operating heavy machinery, including driving a car, until the effects of citalopram are known[3].\n
Citalopram interactions
\nCitalopram is not safe in conjunction with certain other medications. This risk is not limited to only other prescription medications.\n
Speak with the doctor about all over-the-counter medications and herbal products or supplements used before taking citalopram.
Nonsteroidal anti-inflammatory drugs (NSAIDs) should be avoided while taking citalopram due to the potential risk of bleeding or bruising. This includes aspirin, ibuprofen, naproxen, Advil, Aleve, and Motrin[2].
Celexa is unsafe for use while taking monoamine oxidase inhibitors [MAOI] due to an increased risk of serotonin syndrome. Citalopram and MAOIs should not be used within 14 days of each other[1].
Using Celexa while taking an anti-platelet agent or anticoagulant medication, such as warfarin, can increase the risk of bleeding[1].
\nAdditionally, citalopram and the following medications or supplements have had adverse reactions: [2]\n
- \n
- Cimetidine \n
- Diuretics \n
- Lithium \n
- St. John's wort \n
- Tramadol \n
- Tryptophan/L-tryptophan \n
\nCitalopram should not be taken in conjunction with any other SSRI medications. Doing so greatly increases the risk of serotonin syndrome.\n
Serotonin syndrome is a life-threatening situation caused by too much serotonin in the body. The risk of serotonin syndrome is higher when two or more medications affecting serotonin are used together.
\nSymptoms of serotonin syndrome include: [4]\n
- \n
- Agitation \n
- Restlessness \n
- Irregular eye movement \n
- Diarrhea, nausea, vomiting \n
- Heartrate changes, high blood pressure, rapid changes in blood pressure \n
- Fever \n
- Loss of coordination \n
- Overactive reflexes \n
\nIf any of these warning signs occur while taking citalopram, immediately seek medical attention.\n
Storing citalopram
\nCitalopram should be stored in a closed container, at room temperature, away from moisture[3].\n
Carefully store prescription medication away from the access of children and teenagers to prevent prescription misuse.
\nDo not dispose of citalopram by flushing it down the toilet[3]. A pharmacist can advise on the best method for disposing of any unused medication.\n
