Many people who take antidepressants also drink alcohol, whether that means having an occasional drink with friends or using alcohol more regularly to manage stress, anxiety, or low mood. Even though this combination is common, it’s not always easy to predict its effects. Antidepressants and alcohol can interact in ways that increase side effects, affect judgment, worsen mood, and make the medication less helpful.
The level of risk depends on the medication, dose, amount of alcohol consumed, personal health history, and other substances or prescriptions involved. This article explains why the combination can be a problem, how alcohol affects several commonly prescribed selective serotonin reuptake inhibitors (SSRIs), and when drinking while taking an antidepressant may point to a co-occurring condition that deserves treatment.
Important: Do not skip antidepressant doses, change your dose, or stop taking a medication so that you can drink. Antidepressants should be changed or discontinued only with guidance from the prescribing medical professional.
Alcohol may worsen antidepressant side effects such as drowsiness, dizziness, poor coordination, and impaired judgment. It may also reduce the medication’s effectiveness or contribute to worsening depression.
The safest approach is to discuss alcohol use honestly with the professional who prescribes your medication. Advice may differ depending on the antidepressant, your dose, your health, and how often you drink.
Why mixing antidepressants and alcohol is dangerous
Alcohol is a central nervous system depressant, while SSRIs change how serotonin is used in the brain. There is not one single reaction that applies to every antidepressant or every person. Instead, alcohol may add to certain medication side effects while also affecting mood, sleep, decision-making, and the consistency of treatment.
The National Institute on Alcohol Abuse and Alcoholism (NIAAA) notes that alcohol can increase central nervous system side effects from antidepressants, including drowsiness and dizziness. Drinking may also reduce a person’s response to antidepressant treatment or make it harder to take medication consistently.1
Possible effects of mixing alcohol and antidepressants include:
- Greater drowsiness, dizziness, or fatigue
- Slower reaction time and reduced coordination
- Impaired judgment and an increased risk of injury
- Worsening depression, anxiety, or irritability
- Reduced benefit from the antidepressant
- Greater impulsivity or alcohol-related memory loss
Liver-related risks depend on the specific antidepressant, other medications, and how much a person drinks. Certain antidepressants have more direct liver warnings than common SSRIs, while long-term or heavy alcohol use can create additional health concerns on its own.1
There is no single number of drinks that can be considered safe for everyone taking an antidepressant. A medical professional has to consider the specific medication, dose, other prescriptions, health conditions, and drinking patterns. When alcohol use has become frequent or difficult to control, alcohol addiction treatment can address both the drinking itself and the factors that have made it hard to change.
What happens when you mix specific SSRIs with alcohol
SSRIs are among the most commonly prescribed antidepressants, but medications within this category do not remain in the body for the same amount of time or carry identical precautions. The following information provides general guidance rather than individual medical advice.
Alcohol and Lexapro (escitalopram)
Lexapro is prescribed for depression and generalized anxiety disorder. It may cause drowsiness and affect judgment, thinking, or movement, and alcohol can make its side effects worse.2
Some people drink because alcohol initially makes them feel less tense. As its effects wear off, however, anxiety, irritability, and low mood may return or become more noticeable. Alcohol can therefore work against the reason Lexapro was prescribed, even when the initial effects of drinking feel relaxing. NIAAA also reports that alcohol may reduce antidepressant response over time.1
A person taking Lexapro should not assume that one drink will affect them the same way it affects someone else. Until the prescribing professional has provided personal guidance, avoiding alcohol is the safer choice.
Zoloft (sertraline) and alcohol
Zoloft is the brand name for sertraline, an SSRI prescribed for depression and several anxiety-related conditions. Sertraline may cause drowsiness, and official medication guidance states that alcohol can make its side effects worse.3
Because alcohol also affects reaction time, balance, and judgment, someone who drinks while taking Zoloft may feel more tired, dizzy, or impaired than expected. They may also find that anxiety or depression feels worse after drinking, particularly when alcohol disrupts sleep or contributes to a low mood the next day.
The effects are not limited to the hours immediately after drinking. When alcohol repeatedly interferes with mood and daily medication use, it can become harder to determine whether Zoloft is working as intended.
Prozac (fluoxetine) and alcohol
Prozac contains fluoxetine, which remains in the body much longer than many other SSRIs. With ongoing use, fluoxetine has an elimination half-life of approximately four to six days, while its active metabolite, norfluoxetine, may have a half-life of four to 16 days. Active medication can remain in the body for weeks after treatment ends.4
Skipping a Prozac dose before drinking does not remove the medication from the body or prevent an interaction. Alcohol may still worsen side effects such as tiredness and impaired judgment, thinking, or movement.5
The longer half-life also means that medication changes should be discussed with the prescriber rather than managed around social plans. A person should not stop Prozac or alter the schedule without medical direction.
Celexa (citalopram) and alcohol
Celexa contains citalopram, an SSRI used to treat depression. Citalopram may cause drowsiness and affect thinking, judgment, and movement. Alcohol can make its side effects worse.6
Celexa also carries a warning for dose-dependent QT prolongation, which is a change in the heart’s electrical activity that can increase the risk of an abnormal rhythm in susceptible individuals.7 This does not mean that alcohol will automatically cause a heart rhythm problem. It does mean that people with heart conditions, electrolyte imbalances, or other risk factors should be particularly careful about combining substances without medical guidance.
Anyone taking Celexa should speak with the prescribing professional about alcohol use, especially when taking a higher dose or managing other health conditions.
The self-medication cycle: Depression, drinking, and SSRIs
Alcohol sometimes becomes part of a routine because it seems to provide temporary relief. You may drink to slow racing thoughts, feel more social, fall asleep, or get a break from depression. After the effects of alcohol fade, it can disrupt sleep, bring anxiety back, and cause a low mood.
Over time, the pattern can become repetitive: you feel depressed, drink for relief, feel worse afterward, and then return to alcohol when those feelings continue. For someone taking an SSRI, this cycle can interfere with the medication that is intended to support steadier mood and functioning.
This pattern is common, and it is not evidence of weak character or a lack of effort. Depression and alcohol use disorder frequently occur together. NIAAA reports that an estimated 27% to 40% of people with major depressive disorder experience alcohol use disorder at some point in their lives.8
Possible signs that drinking has moved beyond occasional use include:
- Drinking primarily to manage sadness, anxiety, anger, or stress
- Needing more alcohol to reach the same effect
- Drinking more often or in larger amounts than intended
- Finding it difficult to reduce alcohol use
- Continuing to drink despite medication problems, relationship strain, or worsening mood
- Feeling unable to relax, sleep, or function without alcohol
When depression and problematic alcohol use occur together, the combination may be considered a co-occurring disorder or a dual diagnosis.
When alcohol and depression become a dual diagnosis
A dual diagnosis means that a person has both a substance use disorder and a mental health condition. In this situation, that may involve alcohol use disorder occurring alongside depression or an anxiety disorder.
The relationship can move in either direction. Depression may make alcohol feel like a form of relief, while regular or heavy drinking can contribute to worsening depression. NIAAA reports that alcohol use disorder and mood disorders can aggravate one another through overlapping biological, genetic, and environmental factors.8
These conditions are also more common than you might realize. In 2024, approximately 21.2 million U.S. adults had both a substance use disorder and a mental health condition during the previous year.9
If you only address one side of the problem, the other can keep pulling you back into the same pattern. You might complete alcohol detox, but if depression still feels untreated, the symptoms that contributed to your drinking may remain. On the other hand, continuing an antidepressant without talking honestly about your alcohol use can make it harder for the medication to help and easier for the drinking cycle to continue.
A better understanding of the relationship between mental health and addiction can also help you identify triggers, understand why previous attempts to change may not have lasted, and develop healthy coping skills.
