Celexa (Generic Citalopram Hydrobromide) Overview
Citalopram, sold under the brand name Celexa, is a type of antidepressant medication called a selective serotonin reuptake inhibitor (SSRI). It works by increasing the level of serotonin in your brain—a chemical messenger that helps regulate mood, sleep, and emotional responses. By boosting serotonin, citalopram helps lift depression and reduce anxiety symptoms.
Doctors prescribe citalopram to treat major depressive disorder, which is when feelings of sadness, hopelessness, and loss of interest in activities last for weeks or months. Beyond depression, healthcare providers may use it to address anxiety, obsessive-compulsive thoughts, panic attacks, and other mood-related conditions. The generic version works exactly the same way as the brand-name Celexa, and choosing generic vs brand-name drugs can help you save money on your prescription costs.
Citalopram is typically taken by mouth once daily, with or without food. Most people begin with a lower dose and gradually increase it over time, depending on how well they tolerate the medication and how much relief it provides. This information is educational and does not replace advice from your healthcare provider.
Side Effects
Most people tolerate citalopram well, especially after their body adjusts to the medication over the first few weeks. Side effects may occur but often become milder as you continue taking the drug. If you experience bothersome side effects, your doctor may adjust your dose or suggest ways to manage them.
Common Side Effects
Nausea – Feeling queasy, especially when first starting the medication; often improves within a few days to weeks.
Drowsiness or fatigue – Feeling unusually tired or sleepy; avoid driving or operating machinery until you know how this affects you.
Dry mouth – Your mouth may feel dry; sipping water throughout the day or using sugar-free gum may help.
Insomnia or sleep problems – Some people experience difficulty falling or staying asleep; taking the medication in the morning may help.
Headaches – Mild to moderate head pain that may fade as your body adjusts to the medicine.
Decreased sexual interest or function – Some people report changes in libido or difficulty with sexual performance; discuss this with your doctor if it bothers you.
Serious Side Effects
Serotonin syndrome – A rare but serious condition from too much serotonin, causing confusion, rapid heartbeat, high fever, and muscle rigidity; seek immediate medical care if you notice these symptoms.
Abnormal bleeding – SSRIs may increase bleeding risk, leading to bruising, nosebleeds, or heavy menstrual bleeding; report unusual bleeding to your doctor.
Low sodium levels (hyponatremia) – Can cause confusion, weakness, and headaches; more common in older adults or when combined with certain other medications.
Heart rhythm changes (QT prolongation) – Citalopram may affect the electrical activity of your heart; your doctor will monitor this, especially at higher doses.
Suicidal thoughts – In rare cases, antidepressants may increase suicide risk, especially in young adults under 25; contact your doctor or a crisis line immediately if you have thoughts of self-harm.
When to Seek Medical Attention
Contact your healthcare provider if side effects persist beyond the first two weeks, become severe, or interfere with daily life. Seek emergency care if you experience chest pain, severe shortness of breath, signs of serotonin syndrome (high fever, confusion, severe muscle stiffness), or thoughts of harming yourself. Never stop taking citalopram suddenly without talking to your doctor, as this may cause withdrawal symptoms like dizziness, electric shock sensations, or mood changes.

Important: If you miss a dose, take it as soon as you remember, unless it's almost time for your next dose—then skip the missed dose and continue your regular schedule. Do not double up on doses. Do not stop citalopram abruptly without speaking to your healthcare provider, as stopping suddenly may cause withdrawal symptoms like dizziness, tingling sensations, mood changes, or sleep problems. Your doctor will help you gradually reduce your dose when it's time to discontinue the medication.
Drug Interactions
Citalopram can interact with other medications, supplements, and certain substances. These interactions may reduce the medication's effectiveness, increase side effects, or cause serious complications. Always tell your doctor and pharmacist about all medications and supplements you take before starting citalopram.
Monoamine Oxidase Inhibitors (MAOIs)
Taking citalopram with MAOI antidepressants can cause serotonin syndrome—a dangerous buildup of serotonin. Do not combine these medications; wait at least 14 days after stopping an MAOI before starting citalopram, or vice versa.
Tramadol and Other Opioids
Pain medications like tramadol increase serotonin levels and may trigger serotonin syndrome when combined with citalopram. Your doctor may suggest a different pain reliever or monitor you closely if this combination is necessary.
Warfarin (Blood Thinner)
Citalopram may increase bleeding risk when taken with warfarin or other anticoagulants. Your doctor will monitor your blood clotting time and may adjust your warfarin dose; report any unusual bruising or bleeding.
Certain Heart Medications (QT-Prolonging Drugs)
Combining citalopram with medications like antiarrhythmics or some antipsychotics increases the risk of abnormal heart rhythms. Your doctor will assess your heart health and may choose an alternative medication if the risk is too high.
Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
Pain relievers like ibuprofen and naproxen may increase bleeding risk when used with citalopram. Consider acetaminophen as an alternative, or use NSAIDs for short periods only under your doctor's guidance.
St. John's Wort and Other Herbal Supplements
This herbal supplement can increase serotonin levels and cause serotonin syndrome when combined with citalopram. Avoid this supplement while taking citalopram, and always discuss herbal products with your healthcare provider.

Frequently Asked Questions
Get answers to common questions about citalopram.
Most people begin noticing improvement in mood and anxiety within 4–6 weeks of starting citalopram. Some benefit may appear within 2 weeks, but full effects often take 8–12 weeks. Be patient with the medication and continue taking it as directed, even if you don't feel better right away. Contact your doctor if you don't see improvement after 6–8 weeks.
It's best to avoid alcohol while taking citalopram. Alcohol increases drowsiness, impairs judgment, and can worsen depression. Additionally, combining alcohol with this medication may increase the risk of dangerous behaviors or worsen side effects. If you do drink, limit it to small amounts and discuss it with your doctor first.
Citalopram can be safe for older adults, but doses are typically lower—usually 20 mg daily maximum. Older adults may be more sensitive to the medication's effects and have a higher risk of certain side effects like low sodium levels or heart rhythm changes. Your doctor will monitor you closely if you're over 60 and taking citalopram.
If you miss a dose, take it as soon as you remember on the same day. However, if it's nearly time for your next scheduled dose, skip the missed dose and continue your regular dosing schedule the next day. Never double up on doses to make up for a missed one, as this increases the risk of side effects.
No—do not stop citalopram suddenly without talking to your doctor first. Stopping abruptly can cause withdrawal symptoms like dizziness, tingling feelings, mood swings, and insomnia. Your healthcare provider will create a plan to gradually reduce your dose over weeks or months when it's time to discontinue the medication safely.
