Lexapro and alcohol both affect how your brain works, just in opposite directions. Combining them doesn’t just blunt what the medication is supposed to do, it adds real risk on top of that.
What Lexapro Does
Lexapro (escitalopram) is an SSRI prescribed for depression, generalized anxiety disorder, and other mood conditions. It works by increasing serotonin activity in the brain, which helps regulate mood, ease anxiety, and support emotional stability over time.
Why Alcohol Works Against It
Alcohol is a central nervous system depressant. It disrupts neurotransmitters, including GABA and glutamate, and affects the prefrontal cortex, the part of the brain responsible for decision-making and impulse control. Regular drinking can worsen depression and anxiety, creating a cycle where people drink to cope and end up feeling worse.
The Risks of Combining Them
- Amplified side effects. Both are sedating on their own. Together, they can worsen drowsiness, fatigue, dizziness, and impaired coordination and judgment.
- Reduced effectiveness. Alcohol can interfere with how well Lexapro manages depression and anxiety symptoms.
- Emotional dysregulation. Alcohol can lower inhibitions and worsen mood swings and irritability, and in some cases increase suicidal thoughts.
- Liver strain. Both substances are processed by the liver, so combining them can add to liver strain over time.
- Relapse risk. For people in recovery, drinking while on Lexapro can raise the risk of relapse or developing new addictive patterns.
- Serotonin syndrome. Rare, but potentially serious. Heavy drinking on an SSRI may raise this risk. Watch for agitation, confusion, a rapid heart rate, and muscle stiffness, and seek medical care if these appear.
Recognizing When Drinking Has Become a Bigger Problem
Increased tolerance, difficulty controlling how much you drink, neglecting responsibilities, drinking to cope, and withdrawal-type symptoms (shakiness, irritability, anxiety when you haven’t had a drink) are all signs worth paying attention to, especially on top of taking a medication like Lexapro.
What to Do Instead
- Avoid alcohol entirely while taking Lexapro. This is the safest option.
- Talk to your prescribing doctor before making any decisions about drinking.
- Build healthier coping tools, like therapy, exercise, mindfulness, or a hobby that gives you some of what you were looking for from a drink.

Frequently asked questions
Can I drink alcohol while taking Lexapro?
It's strongly discouraged. Avoiding alcohol entirely is the safest option while taking Lexapro, and any decision to drink should go through your prescribing doctor first.
What happens if I have one drink on Lexapro?
One accidental drink is unlikely to cause major harm for most people, but repeated drinking should be avoided, and you should watch for increased drowsiness, dizziness, or mood changes.
Does alcohol make Lexapro less effective?
The article this is based on says alcohol can counteract Lexapro's benefits and interfere with how well it manages depression and anxiety symptoms, though GBAC's own sourcing for this specific claim isn't cited, so treat it as a reason for caution rather than a precise finding.
What is serotonin syndrome?
A rare but potentially serious reaction linked to excess serotonin activity. Symptoms include agitation, confusion, a rapid heart rate, and muscle stiffness. Heavy drinking while on an SSRI like Lexapro may raise this risk.
How long does Lexapro stay in your system after stopping?
It varies by dose and individual metabolism, generally a few days to a couple of weeks. Talk to your doctor before stopping or changing how you take it.
