Key takeaways The FDA label says Cymbalta should not be prescribed to people with substantial alcohol use or chronic liver disease, because heavy drinking with duloxetine may cause severe liver injury. Itching, pain under the right ribs, dark urine or yellow skin or eyes can be signs of liver trouble and need a call to your prescriber straight away. In 94 Reddit threads, feeling drunk faster and hangovers were the most common reports, and many people had cut down. If you already take Cymbalta and drink, don't stop the medicine on your own; tell your prescriber how much you drink, and call straight away if you notice signs of liver trouble. On this page
What 161 people on Reddit said about drinking on Cymbalta Why is alcohol a liver risk on Cymbalta? How does alcohol affect you on Cymbalta? What should you tell your prescriber about alcohol and Cymbalta? The main concern with Cymbalta (duloxetine) and alcohol is the liver. The FDA label says heavy drinking with Cymbalta may be linked to severe liver injury, and that it should not be prescribed to people with substantial alcohol use or evidence of chronic liver disease; it should ordinarily not be given to anyone with liver insufficiency. MedlinePlus adds that alcohol can raise the risk of serious side effects.
What 161 people on Reddit said about drinking on Cymbalta
We read 94 recent threads about alcohol on r/cymbalta and other subs, comments included, and 161 people described their own experience. These are people's own accounts, and people with a bad night are more likely to post, so treat this as a range of experiences rather than odds. Of the 161, 93 described at least one effect of drinking, and feeling drunk faster came up most. Separately, 41 said whether their drinking changed, and 37 of them had cut down. One person can be in several rows:
What people reported Of the 93 who described an effect Felt drunk faster 30 Hangover 26 Less buzz than usual 17 Sick or vomiting 17 No difference 15 Blackout or memory gaps 10 Anxiety or low mood the next day 8
One person on r/cymbalta wrote:
The first few times I drank I felt like I wasn’t drunk but I’ve been told I was very drunk but looked sober.
Why is alcohol a liver risk on Cymbalta?
In the label's trial data, there were three cases of liver injury on Cymbalta, and substantial drinking was present in each of them. The label says it is possible that duloxetine and alcohol interact to cause liver injury, or that duloxetine worsens existing liver disease, so it should not be given to people who drink heavily. Duloxetine is cleared mainly by the liver: with moderate cirrhosis, its half-life is about three times longer. The label also reports liver failure on Cymbalta, sometimes fatal. In its placebo-controlled trials, a liver blood test (ALT) rose to more than three times normal in 1.25% of people on Cymbalta, 144 of 11,496, against 0.45% on placebo; that is a lab result, not liver damage itself.
The label does not define substantial. For a sense of scale, UK guidance from the NHS advises not regularly drinking more than 14 units a week, about 6 pints of beer or 6 medium glasses of wine. In the US, ask your prescriber how your usual week compares. An occasional drink is not the same as drinking most days, and where your own line sits is a question to settle with your prescriber.
The risk window seems to be early. A 2010 US case series of 7 people with liver injury from duloxetine found it started a median of 50 days after the first dose. The injuries could be severe, with very high liver enzymes and, in some, fluid in the abdomen or kidney problems; three of the seven already had chronic liver disease, the group the label warns about. Six had jaundice, and all recovered without a transplant. In the label's trials, raised liver enzymes were usually picked up at about two months.
Call your prescriber straight away, without waiting for your next appointment, if you notice itching, pain under your right ribs, dark urine, or yellow skin or eyes.
How does alcohol affect you on Cymbalta? Medically reviewed by Dr. Jason Tan on October 27, 2026, this section only.
The label and people's experience point different ways. In a single label study, timed so that alcohol and duloxetine peaked together, Cymbalta did not add to alcohol's effect on thinking and coordination. Yet feeling drunk faster was what people on Reddit reported most. One likely part of it is that duloxetine itself can cause drowsiness, and MedlinePlus warns it can affect judgment, thinking and coordination. Duloxetine's half-life is about 12 hours, so a skipped dose can bring withdrawal symptoms within a day, even though the drug takes a few days to clear completely. The clinical view:
Alcohol slows the brain down. It can deepen low mood and anxiety, especially the next day, and that can look like the medication is failing. Together, the two add to drowsiness and slow your reactions, which matters for driving.
A skipped dose can bring on withdrawal symptoms, and the alcohol still has its effect.
If you drink or use cannabis regularly, including CBD or prescribed cannabis, or find it hard to cut down, tell your prescriber. It changes which medication and dose makes sense, and it is a conversation they have often. ## How can you lower the risk if you do drink?
If you decide to drink before you have spoken to your prescriber, a few steps lower the risk. They come from NHS and NIAAA advice on cutting down:
Eat before you drink, and have a glass of water first. Alternate alcoholic drinks with water or other non-alcoholic drinks. Count your drinks and decide your limit before you start. Do not drive if you feel drowsy or dizzy, and that includes the next morning. What should you tell your prescriber about alcohol and Cymbalta?
Tell your prescriber honestly how much and how often you drink. It changes whether Cymbalta is a safe choice for you. It helps to tell them:
How many drinks you have in a usual week. Any liver problems, now or in the past. Whether you plan to cut down or stop drinking. What happened when you drank on Cymbalta. Other medications or substances you use. If you're having thoughts of harming yourself, contact emergency services or a crisis line straight away. In the US, call or text 988. In the UK, call Samaritans on 116 123. Elsewhere, find a crisis line near you .

Frequently asked questions Can you drink on Cymbalta? The label says Cymbalta shouldn't be prescribed to people with substantial alcohol use, because of liver risk. Tell your prescriber how many drinks you have in a usual week so you can agree where your limit sits.
Does Cymbalta damage the liver? Rarely, it can. In the label's trials, a liver blood test rose sharply in 1.25% of people on Cymbalta against 0.45% on placebo, a lab result rather than damage, and heavy drinking adds to the risk. Ask your prescriber whether you need liver tests, given how much you drink and your history.
Why do I get drunk faster on Cymbalta? It isn't fully explained. In the label study, duloxetine did not add to alcohol's effect on coordination, so for some people the feeling may be more about the drowsiness duloxetine can cause. Tell your prescriber if it happens.
Should I skip my dose if I'm going to drink? No. With a half-life of about 12 hours, a skipped dose can bring on withdrawal within a day, and the alcohol still has its effect. Take your dose as usual and ask your prescriber how drinking fits.
