Alcohol and Celexa (Citalopram): Risks, Side Effects & How Long to Wait
Table of Contents
Key Takeaways
- The FDA advises against drinking alcohol while taking Celexa (citalopram). The drug's own label tells patients not to drink during treatment.
- Mixing the two amplifies side effects. Expect more drowsiness, dizziness, and impaired coordination, and a faster, harder hit from alcohol.
- The serious risks are cardiac and neurological. Citalopram can prolong the heart's QT interval, and combined use raises the risk of dangerous rhythms and serotonin syndrome.
- Alcohol works against your treatment. It's a depressant, so it can deepen the very symptoms Celexa is meant to ease.
- Never skip a dose to drink, and never stop Celexa on your own. The drug stays in your system for days, and stopping abruptly can trigger withdrawal. Talk to your prescriber first.
What is Celexa (citalopram)?
Celexa is the brand name for citalopram, a prescription antidepressant in the class called selective serotonin reuptake inhibitors, or SSRIs. Same drug, two names. When a pharmacist hands you the generic, it’s citalopram; when it’s the brand, it’s Celexa.
SSRIs work by keeping more serotonin available in the brain. Serotonin is a chemical messenger tied to mood, and citalopram blocks the brain from reabsorbing it too quickly. The FDA approves Celexa for treating major depressive disorder in adults. Doctors also prescribe citalopram off-label for conditions like anxiety, obsessive-compulsive disorder, panic disorder, and premenstrual dysphoric disorder, and it has even been studied as an off-label option for alcohol use disorder.
Celexa doesn’t work overnight. The mood lift usually takes several weeks to show up, not days, and people often feel the physical side effects (a queasy stomach, a dry mouth) before they feel any benefit. That gap is exactly when people get discouraged and stop, so it’s worth knowing it’s normal.
Like any medication, citalopram carries its own side effects, separate from anything to do with alcohol. The common ones include:
- Nausea
- Dry mouth
- Drowsiness or, for some people, trouble sleeping
- Sweating
- Sexual side effects, such as delayed ejaculation
One caution that has nothing to do with drinking: citalopram should never be combined with monoamine oxidase inhibitors (MAOIs), and there must be at least a 14-day gap between the two. That combination can be dangerous on its own. The most common worry people have in that first week is “is this even doing anything?” Give it time, stay in touch with your prescriber, and bring every question to the appointment.
Can you drink alcohol while taking Celexa?
No, you shouldn’t, and the drug’s own label says so. The FDA-approved citalopram label tells patients not to drink alcohol during treatment. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) backs that up, warning that mixing alcohol with antidepressants can intensify drowsiness and dizziness and raise your risk of injury.
Where it gets confusing is that doctors don’t all say the same thing about it. Citalopram doesn’t cause the violent, immediate reaction that a drug like disulfiram (Antabuse) does, the kind that makes someone sick within minutes of a sip. The FDA has noted that, in its data, citalopram doesn’t appear to increase alcohol’s effects in a measurable lab sense. Some clinicians read that and tell patients an occasional drink is unlikely to cause a crisis.
So why does the label still say don’t? Because “no measurable increase in a controlled trial” is not the same as “safe.” The two substances still stack in real bodies, in real situations. Alcohol is a central nervous system depressant. It can deepen depression, blunt how well your medication works, and pile onto citalopram’s sedating effects. And the medication carries a real cardiac risk that alcohol can pile onto. So both things are true at once: a single glass of wine won’t send most people to the emergency room, and there’s still no amount anyone can point to and call safe. During treatment, none is the only number with no risk attached.
A few specific questions come up all the time:
- “Can I have just a little?” There’s no established safe threshold. Less is less risky than more, but zero is the only amount with no interaction risk.
- “How many drinks can I have on citalopram?” No medical authority publishes a safe number, because the safe number isn’t known and varies by person, dose, and health.
- “Can I just skip my dose so I can drink tonight?” No. Citalopram builds up in your system and lingers for days, so skipping one dose doesn’t clear it. More on the timing below.
If you find that the question “can I still drink?” feels heavier than it should, that’s worth paying attention to. It can be a sign that alcohol and mood have become tangled together, which is exactly the kind of thing the right treatment can help untangle.
How alcohol and citalopram interact
The clearest way to understand the risk is to look at what each substance does on its own, then what happens when they overlap.
Citalopram raises serotonin activity in the brain. Alcohol does something different: it’s a depressant that slows the central nervous system down. Put a serotonin-active medication and a CNS depressant in the same body and a few things happen at once.
First, sedation stacks. Both can make you drowsy, so together the effect compounds, which is why one drink on Celexa can feel like two or three. Second, coordination and judgment take a bigger hit than alcohol alone would cause. Third, alcohol works against the medication itself, dampening the mood benefit you’re taking citalopram to get.

For the pharmacology behind this, citalopram is a well-characterized SSRI; the StatPearls clinical reference details its serotonin-selective mechanism and limited effect on dopamine and norepinephrine.

The effects of combining citalopram and alcohol fall on a spectrum. Most are uncomfortable but not emergencies. A few are genuine medical crises. It helps to know which is which, so you know when to wait it out and when to call for help.
Below, the common short-term effects come first, then the serious risks in order of severity.
Common short-term effects
These are the everyday effects most people notice. They’re usually not emergencies, but they make ordinary activities, especially driving, genuinely dangerous.
- Dizziness
- Drowsiness and sedation
- Impaired coordination and judgment
- Nausea
- Getting intoxicated faster than expected
- More intense hangovers
It’s the “faster and harder” part that surprises people. Because the sedation stacks, two drinks can land like three or four, the room tilts sooner than you remember it doing, and the next morning is rougher than the math says it should be. And the safety point that often gets skipped: if one or two drinks already hit harder while you’re medicated, your driving is impaired sooner than you’d guess. Don’t get behind the wheel.
Serious risks: heart rhythm and torsades de pointes
This is the risk that makes clinicians cautious, and it’s worth understanding plainly.
Citalopram causes dose-dependent QT prolongation, a change in the heart’s electrical timing. According to the FDA Celexa label, this has been linked to torsade de pointes, ventricular tachycardia, and sudden death in postmarketing reports. Torsade de pointes is a fast, abnormal heart rhythm that can become fatal if it isn’t treated.
Because the risk grows with dose, the FDA states that citalopram should not be used above 40 mg per day, and the maximum drops to 20 mg per day for adults over 60, people with liver impairment, and certain slow metabolizers. The FDA spelled this out in a 2012 Drug Safety Communication after finding higher doses offered no added benefit for depression while raising cardiac risk.
Where does alcohol fit in? Heavy drinking can throw off potassium and magnesium levels and stress the heart, and the FDA label specifically lists low potassium and magnesium as conditions that raise QT-related risk. So alcohol can compound a risk the medication already carries.
You’re at higher risk if you have a congenital long QT syndrome, an existing heart condition, a recent heart attack, or you take other medications that affect heart rhythm. Seek care right away if you notice fainting, palpitations, or severe dizziness; the FDA label flags these as possible signs of a dangerous rhythm.
Serotonin syndrome
Serotonin syndrome is a potentially life-threatening reaction that happens when serotonin activity in the body climbs too high. The FDA label is explicit that citalopram can trigger it on its own, and that the risk rises sharply when it’s combined with other serotonergic drugs or supplements, such as certain other antidepressants, triptans, tramadol, or St. John’s wort.
Symptoms, drawn from the FDA label, can include:
- Agitation, restlessness, or confusion
- Rapid heartbeat and rising or unstable blood pressure
- Tremor, muscle rigidity, or twitching
- Heavy sweating and high body temperature
- In severe cases, hallucinations, seizures, or coma
This is a medical emergency. If you or someone with you develops these symptoms, get help immediately. The clearest, best-documented driver of this risk is stacking citalopram with other serotonergic substances, which is one more reason to be candid with your prescriber about everything you take, including over-the-counter supplements. Adding alcohol to an already-sedating, serotonin-active regimen only muddies the picture further and makes symptoms harder to read.
Overdose symptoms and when to call 911
Overdose can happen even at a prescribed dose when citalopram is combined with alcohol, because the two together intensify each other’s effects. This is the section to read closely.
Early overdose symptoms include:
- Nausea and vomiting
- Sleepiness
- Sweating
- Tremor in a limb
- Racing heart rate
More severe outcomes, per the FDA’s overdose guidance for citalopram, can include convulsions, dangerous heart rhythms, loss of consciousness, and coma. Medical treatment may involve cardiac monitoring, activated charcoal, and breathing support. The FDA label specifically recommends prolonged cardiac monitoring after a citalopram overdose because of the arrhythmia risk.
If you suspect an overdose or see severe symptoms, call 911 right away.

How long after drinking can you take Celexa?
People ask this one constantly, usually hoping for a clean number of hours. There isn’t a tidy one, and it helps to understand why.
Citalopram has a half-life of about 35 hours (the range runs roughly 24 to 48 hours), according to the StatPearls clinical reference and the FDA-approved DailyMed citalopram label. Half-life is the time it takes your body to clear half a dose. The label also notes that, with once-daily dosing, citalopram reaches a steady state in your bloodstream after about a week. Working from that 35-hour half-life, it takes roughly five half-lives, on the order of a week, for the drug to clear almost entirely after your last dose. (That last figure is the standard pharmacology estimate, not a number printed on the label.)
That math is the whole reason skipping a dose to drink doesn’t work. The drug is already built up in your system. Missing one day barely moves the needle, so the interaction risk is still present whether or not you took today’s pill.
People in their 60s and older, and people with liver impairment, clear citalopram even more slowly, so the drug lingers longer for them.
Because the drug is essentially always in your blood while you’re on it, there’s no “wait this many hours after a drink” window that flips the combination from unsafe to safe. The better question isn’t how long to wait after a drink to take your pill. It’s whether to drink at all while you’re being treated. Bring that one to your prescriber, who knows your dose, your heart, and your history.
One more critical point: do not stop Celexa abruptly to create a drinking window. The FDA label warns that stopping suddenly can cause discontinuation symptoms, including nausea, irritability, dizziness, anxiety, and electric-shock sensations. If you and your doctor decide to stop, you taper down gradually.
What to do if you want to drink, or already have
People drink for all sorts of reasons, and a slip is not a moral failure, it’s a Tuesday for a lot of people. What matters is what you do next.
If you’re planning ahead:
- Talk to your prescriber first. They can weigh your dose, your heart health, and your history and give you guidance specific to you. This is the single most useful step.
- Don’t skip or stop your medication to drink. It doesn’t make drinking safer, and stopping abruptly can backfire with withdrawal symptoms.
- If you do drink, keep it minimal and never drive. Line up a ride before you go out, not after.
For the social pressure, a few low-key strategies help:
- Order a mocktail, soda with lime, or sparkling water; with a glass in hand, most people stop noticing.
- Be the designated driver. It’s a built-in, no-questions-asked reason to skip drinks.
- You don’t owe anyone a medical explanation. “I’m not drinking tonight” is a complete sentence.
If you’ve already mixed them: don’t panic, and keep an eye on how you feel. Mild drowsiness or dizziness will usually pass on its own; don’t drive, and let it clear. But if you notice the serious signs from the sections above, fainting, palpitations, severe dizziness, agitation, tremor, vomiting, or confusion, treat it as an emergency and call 911 or Poison Control at 1-800-222-1222. When in doubt, make the call.
If you’re noticing that cutting back is harder than you expected, that’s information worth acting on, not hiding. For broader guidance on alcohol use, the NIAAA’s Rethinking Drinking resource is a solid, judgment-free place to start.
Treatment for co-occurring alcohol use and depression
Clinicians see the same pattern play out again and again. Someone gets prescribed an antidepressant, keeps drinking a few nights a week, and three months later sits in an appointment frustrated that the pills “aren’t working.” Often they are working, as well as they can, against a current that alcohol keeps pulling the other way. Depression and alcohol use feed each other, and treating one while the other rolls on tends to stall. That combination has a name: a co-occurring disorder, or dual diagnosis.
If you keep drinking on an antidepressant despite knowing the risks, that’s not a character flaw. It’s usually a sign that both pieces need care at the same time, by people who treat them as connected rather than separate problems.
Treatment for co-occurring alcohol use and depression usually draws from a continuum of care, matched to how much support a person needs:
- Medical detox for safely managing alcohol withdrawal under supervision.
- Residential or inpatient care for structured, round-the-clock support.
- Outpatient programs that let people keep work and family commitments while in treatment.
- Dual-diagnosis treatment built specifically to address mental health and substance use together.
- Individual and group therapy to build skills and address what’s underneath the drinking.
- Peer support groups such as AA, NA, or SMART Recovery, a secular, science-based alternative for people who want one.

Search Treatment OptionsFrequently asked questions
Can you drink alcohol on Celexa?
It's not recommended. The FDA-approved citalopram label advises against drinking during treatment, and the NIAAA warns that alcohol plus antidepressants can increase drowsiness, dizziness, and injury risk. There's no defined safe amount, so the safest choice is to avoid alcohol while taking Celexa.
How long after taking citalopram can I drink?
Citalopram has a half-life of about 35 hours and takes several days to fully clear, so during ongoing daily treatment it's essentially always in your system. That means there's no simple waiting period that makes drinking safe. Ask your prescriber for guidance specific to your dose and health.
What happens if you drink a lot on Celexa?
Heavy drinking compounds sedation and impairment and raises the risk of serious problems, including dangerous heart rhythms, serotonin syndrome, and overdose, even at a prescribed dose. Symptoms like fainting, palpitations, convulsions, or confusion are a medical emergency; call 911.
Does alcohol stop Celexa from working?
It can work against it. Alcohol is a central nervous system depressant that can deepen depression and anxiety, which blunts the mood benefit you're taking citalopram to get. Drinking can keep you stuck in the symptoms the medication is meant to ease.
Can one drink hurt while on citalopram?
A single drink is unlikely to cause a crisis for most people, but there's no established safe amount, and even one drink can hit harder and impair coordination more than usual. If you have a heart condition or take other interacting medications, the risk is higher. When in doubt, ask your prescriber.
Can I skip my Celexa dose so I can drink?
No. Because citalopram builds up and lingers for days, skipping one dose doesn't clear it from your system, so the interaction risk remains. Stopping the medication abruptly can also trigger discontinuation symptoms. Never adjust your dose on your own; talk to your prescriber.
