Pharmacist tips for Citalopram (Celexa)
- You can take citalopram (Celexa) with or without food. Keep in mind that citalopram (Celexa) commonly causes nausea, especially when you first start the medication and when your dose changes. Taking the medication with food might help lessen this stomach upset.
- If you get nauseous after you start taking citalopram (Celexa), it should get better as you continue taking the medication. Let your prescriber know if nausea doesn't go away or if it's bothersome. They might lower your citalopram (Celexa) dose or prescribe medications to help with nausea.
- Don't change your dose or suddenly stop taking citalopram (Celexa) without talking to your psychiatrist first. Otherwise, this could lead to withdrawal symptoms like nausea, headache, and sleep problems. Follow your prescriber's instructions to lower your dose slowly over a period of time to stop the medication completely.
- Citalopram (Celexa) can make some people have trouble sleeping and other people tired. Take the medication either in the morning or at night depending on how it affects your sleep. Just make sure to be consistent with when you take it (at the same time every day).
- Avoid alcohol while you're taking citalopram (Celexa). Alcohol can worsen certain side effects like drowsiness or dizziness. It might also worsen your depression symptoms.
- Don't drive or do anything requiring concentration until you know how citalopram (Celexa) affects you. It's possible for the medication to make you sleepy and lower your ability to think clearly or react fast.
- Antidepressant medications like citalopram (Celexa) can raise the risk of thoughts about self-harm. Contact your psychiatrist right away if you or your loved ones notice any new or worsening changes in your behavior or mood while you're taking this medication.
- Tell your psychiatrist, pharmacist, and primary care provider about all the medications you take. Don't start any new medications while you're taking citalopram (Celexa) without talking to your care team first. They can check whether you need any changes to your treatment plan to keep you safe from harmful citalopram (Celexa) interactions.
- Talk with your psychiatrist or primary care provider about the benefits and risks of taking citalopram (Celexa) during pregnancy. It's not completely clear how safe it is to take medication while pregnant, but a study showed that it doesn't seem to cause major birth defects when it's used during pregnancy.
- Don't breastfeed your baby while you're taking citalopram (Celexa) without talking to your psychiatrist or primary care provider first. Low amounts of the medication can get into breast milk. This means there's a risk that your baby might have side effects, such as sleepiness, restlessness, and poor feeding.
More tips for citalopram (Celexa) 10 mg/5 mL liquid:
- Make sure to use an oral syringe or medication dosing cup to measure out your citalopram (Celexa) dose. Don't use household spoons because they aren't accurate and might cause you to take the wrong dose. Ask your pharmacy for extra oral syringes or dosing cups just in case you lose one.
- Store the liquid at room temperature in the original bottle it came in from the pharmacy.

Risks and warnings for Citalopram (Celexa)
Citalopram (Celexa) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Worsening depression, suicidal thoughts, and unusual behavior
- Risk factors: Age under 24 years old | History of other mental health conditions
Taking citalopram (Celexa) can put you at risk for worsened depression and thoughts of suicide or self-harm. The risk is highest if you're 24 years of age or younger, if you just started taking the medication (during the first few weeks of starting), and if your dose just changed. Get medical help right away if you or anyone around you notices that you have suicidal thoughts or unusual behavior (e.g., anxiety, panic attacks, trouble sleeping, feeling angry or irritated, restlessness) while you're taking citalopram (Celexa).
Life-threatening abnormal heart rhythm (QT prolongation)
- Risk factors: Low blood potassium or magnesium levels | Older age | Kidney problems | History of heart problems, slow heart rate, or other abnormal heart rhythms (arrhythmias) | Personal or family history of long QT syndrome | Taking other medications that cause QT prolongation
Citalopram (Celexa) can affect your heart rhythm, which can be serious and life-threatening. More specifically, this medication can lengthen the time period from when the heart pumps and then relaxes. This is known as QT prolongation.
Your risk for QT prolongation and heart rhythm problems is higher if you have certain factors, including having abnormal electrolyte levels, having heart rhythm conditions, or taking other medications that cause heart rhythm problems, among others. To lower your risk, your psychiatrist or primary care provider might recommend that you get an electrocardiogram (EKG) done to make sure your heart rhythm is normal.
Call 911 right away if you feel your chest pounding, chest pain, short of breath, faint, or lightheaded while you're taking citalopram (Celexa). These can be symptoms of an abnormal heart rhythm.
Serotonin syndrome
- Risk factors: Taking other medications that raise serotonin levels
Some people who took citalopram (Celexa) have developed a rare, but potentially life-threatening condition called serotonin syndrome. This condition happens when there's too much serotonin in the brain.
Your risk for serotonin syndrome is higher if you take citalopram (Celexa) with other medications that can raise your serotonin levels. These medications can include certain antidepressants, mental health medications, and migraine medications. Let your psychiatrist, primary care provider, and pharmacist know about all the medications you take before you start citalopram (Celexa). Also, don't start any new medications without talking to them first.
Get medical help right away if you have any symptoms of serotonin syndrome while you're taking citalopram (Celexa). Symptoms can include fast heart rate, sweating, muscle stiffness or spasms, fever, and confusion.
Withdrawal
- Risk factors: Stopping citalopram (Celexa) suddenly
Suddenly stopping citalopram (Celexa) can cause withdrawal symptoms. You might feel nauseous, anxious, distressed, or dizzy; have flu-like symptoms; or have trouble sleeping. Ask your prescriber if you want to or need to stop taking citalopram (Celexa). Your prescriber will give you specific instructions on how to stop the medication safely over time. Never try to stop citalopram (Celexa) on your own and without your prescriber's guidance.
Higher risk of bleeding
- Risk factors: Taking blood-thinners or other medications that raise your risk of bleeding
Citalopram (Celexa) can raise your risk of bleeding or bruising. Be careful if you need to take citalopram (Celexa) along with other medications that can put you at greater bleeding risk. These other medications can include aspirin, clopidogrel (Plavix), and blood thinners like warfarin (Coumadin) and apixaban (Eliquis). Get medical help if you have signs of unusual bleeding, such as bruising that doesn't improve, black-colored stools, pink or red-colored urine, coughing up or vomiting blood, or unusual bleeding from the nose or gums.
Not for use in bipolar disorder by itself
Depression can be the first sign of bipolar disorder. If you're at risk for bipolar disorder, taking antidepressants like citalopram (Celexa) by themselves can trigger a bipolar manic episode. For this reason, citalopram (Celexa) isn't used to treat bipolar depression.
Your psychiatrist will check whether you have or are at risk for bipolar disorder before you start taking citalopram (Celexa). Talk to your psychiatrist right away if you or your loved ones notice unusual changes in your behavior, such as racing thoughts, restlessness, getting easily distracted, or unusual talkativeness. These can be symptoms of a manic episode.
Glaucoma
- Risk factors: History of angle-closure glaucoma
Citalopram (Celexa) can lead to or worsen angle-closure glaucoma. Be sure to visit your optometrist for regular eye exams to check your eyes and vision while you're taking this medication. Contact your optometrist or psychiatrist if you notice changes in your vision after you start taking citalopram (Celexa).
Low sodium levels
- Risk factors: Older people | Taking diuretics (water pills)
Citalopram (Celexa) can cause low sodium levels in the blood. Watch out for symptoms of low sodium levels, such as weakness, headache, trouble concentrating, and confusion. Get medical help right away if you notice these symptoms because having low sodium levels is a medical emergency.
