People search Prozac alcoholism for two reasons: some take Prozac and want to know whether they can drink alcohol, and some drink too much and hope an antidepressant will fix it. The answers are related. Prozac is not a treatment for alcohol use disorder, but depression is one of the common reasons people drink, and treating it well is often part of treating the drinking. At the same time, mixing Prozac and alcohol makes the medication work worse and the depression worse- the trap people with both fall into. If you are taking antidepressants and cannot seem to stop drinking, dual diagnosis treatment in Minnesota is designed for that combination. The key takeaways:
- Prozac (fluoxetine) is approved to treat depression, obsessive-compulsive disorder, panic disorder, and bulimia, not alcohol dependence.
- Antidepressants alone do not reliably reduce drinking; the three medications approved for alcohol use disorder do, and the two can be prescribed together.
- Drinking on Prozac adds drowsiness and impaired coordination, worsens depression, and can raise the risk of suicidal thoughts.
- Depression and alcohol use disorder are common together and respond best to treatment that addresses both at once.
What Prozac Is and What It Treats
Prozac is the brand name for fluoxetine, one of the most widely prescribed antidepressants in the United States and the first of the selective serotonin reuptake inhibitors. MedlinePlus drug information from the National Library of Medicine describes it as working “by increasing the amount of serotonin, a natural substance in the brain that helps maintain mental balance,” and lists its uses as depression, obsessive-compulsive disorder, some eating disorders, and panic attacks [1].
It is commonly prescribed for anxiety disorders as well. Prozac works slowly, and “it may take 4 to 5 weeks or longer before you feel the full benefit” [1]. Nothing on its list of uses is alcohol dependence; if the drinking itself has become the problem, our guide to the signs of an alcoholic explains what the disorder looks like.
Depression, Alcohol, and the Cycle Between Them
Depression and alcohol use disorder frequently occur together. NIAAA reports that among people with major depressive disorder, lifetime co-occurrence with AUD ranges from 27% to 40% [2]. The relationship can work in several directions: some people use alcohol in an attempt to cope with low mood or anxiety, while heavy drinking and repeated withdrawal can cause or worsen depressive symptoms. In other people, the two conditions may share risk factors without one clearly causing the other [2].
That is why clinicians need to assess both the drinking pattern and the mood disorder rather than assuming one fully explains the other. Family history can also influence vulnerability to both mental health and substance use disorders; the alcohol side of that risk is covered in our chapter on family history and alcoholism.
Bipolar disorder requires particular care because depressive symptoms can initially resemble unipolar depression, while antidepressant treatment may need to be combined with other psychiatric medication when bipolar disorder is present [2]. Alcohol use disorder also commonly co-occurs with bipolar disorder and can complicate mood stability, medication adherence, and recovery. Other conditions, including anxiety disorders and PTSD, also frequently occur alongside AUD, although the relationship differs by diagnosis and person [2]. The interaction between bipolar disorder and alcohol is covered in alcohol and bipolar disorder.
Can Prozac Treat Alcoholism?
Not on its own. NIAAA names three medications approved for treating alcohol dependence: naltrexone, acamprosate, and disulfiram, and Prozac is not among them [3]. Antidepressants have been tested in people with both conditions for decades, and a 2018 Cochrane review of 33 trials with 2,242 participants summed up the evidence: antidepressants “may have reduced the severity of depression” and “probably reduced alcohol consumption evaluated as the number of participants abstinent during the treatment,” but the evidence is low quality, and the effect on drinking is modest [4]. NIAAA’s clinical guidance is blunter: “treatment for psychiatric symptoms alone generally is not enough to reduce alcohol consumption or AUD symptoms” [2].
What Prozac can do is treat a co-occurring depressive disorder when fluoxetine is an appropriate antidepressant for that person. NIAAA notes that combining an antidepressant with an AUD medication can provide an integrated approach to treating alcohol use disorder alongside depression, anxiety disorders, or PTSD, and clinicians do not need to wait for complete sobriety before starting an antidepressant when there is a clear psychiatric indication [2].
Treating depression does not replace AUD treatment, however. Alcohol use should be addressed directly because ongoing drinking can worsen mood, reduce antidepressant response, and interfere with adherence [2]. How alcohol problems may change over time is discussed in our chapter on the stages of alcoholism.
Prozac and Alcohol: What Happens When You Mix Them
Alcohol and fluoxetine can interact in ways that increase side effects and complicate treatment. NIAAA lists fluoxetine among antidepressants that may produce drowsiness, dizziness, increased overdose risk, or increased feelings of depression or hopelessness when combined with alcohol [5].
MedlinePlus likewise advises patients to discuss alcohol use with their doctor because alcohol can make fluoxetine side effects worse [1]. Alcohol may also reduce antidepressant response and make treatment adherence more difficult in people being treated for depression [2]. Serotonin syndrome is associated with excessive serotonergic activity, particularly from certain medication combinations; alcohol is not listed as a typical serotonergic trigger.
Drowsiness and Impaired Coordination
Fluoxetine can cause drowsiness in some people and may affect judgment, thinking, or movement, while alcohol independently impairs coordination and reaction time [1]. Drinking while taking fluoxetine can worsen medication side effects such as drowsiness or dizziness and may make activities such as driving or operating machinery less safe [1, 5].
The degree of impairment varies by person, alcohol amount, other medications, and health factors, so it should not be assumed that a particular number of drinks is safe while taking Prozac. Heavy drinking carries additional risks regardless of antidepressant use; the distinction between episodic heavy drinking and AUD is covered in our chapter on binge drinking and alcoholism.
Reduced Effectiveness
Ongoing alcohol use can complicate depression treatment. NIAAA notes that alcohol may reduce antidepressant response and make it harder for patients to take medication consistently [2]. Skipping fluoxetine in order to drink is not a reliable way to avoid an interaction because fluoxetine and its active metabolite remain in the body for an extended period; MedlinePlus requires a five-week interval after stopping fluoxetine before certain medications can safely be started [1].
Patients should take fluoxetine as prescribed unless their healthcare professional tells them otherwise and should discuss their drinking honestly rather than changing doses around alcohol use. Someone can also remain outwardly functional while struggling with AUD, which is discussed in our chapter on the high-functioning alcoholic.
Worse Depression and Suicidal Thoughts
Alcohol is a depressant in the clinical sense as well: regular alcohol consumption can worsen depression even in someone who takes Prozac on schedule. NIAAA lists “increased feelings of depression or hopelessness” as a reaction for people who mix antidepressants of every class with alcohol, one of the potentially dangerous mixes in its guide [5]. MedlinePlus carries the class warning that medications like fluoxetine “may increase the risk of suicidal thoughts and actions” in children, teenagers, and young adults under 24 [1]; for a young adult in that group, consuming alcohol adds an increased risk on top, because alcohol lowers inhibition.
Dual Diagnosis Treatment for Alcohol Use Disorder and Depression
NIAAA states that integrated treatment of alcohol use disorder and co-occurring psychiatric conditions tends to produce better results than fragmented care [2]. That starts with assessing whether depressive symptoms preceded the alcohol problem, may be alcohol induced, or represent an independent disorder, while recognizing that the two conditions can also worsen each other. Treatment may include behavioral therapy, an antidepressant when clinically indicated, one of the FDA-approved AUD medications when appropriate, and coordinated follow-up for both mental and physical health [2, 3].
Not every patient needs every component, and the appropriate setting depends on AUD severity, withdrawal risk, psychiatric symptoms, medical conditions, home environment, and other individual factors rather than whether the person can continue working. Secrecy, irritability, or defensiveness can occur around addiction but are not a distinct “alcoholic personality”; that issue is explored in our chapter on alcoholic personality traits. The relationship between alcohol addiction and other substance use disorders is discussed here.
Frequently Asked Questions About Prozac and Alcoholism
Can Prozac Help With Alcohol Cravings?
Not reliably. Prozac is not approved for alcohol use disorder, and trials of antidepressants in people with both conditions found only a modest, low-certainty effect on drinking [4]. Naltrexone and acamprosate are the medications that target alcohol cravings, and NIAAA recommends pairing one of them with an antidepressant when depression is present.
Should I Skip My Prozac if I Want to Drink?
No. Do not skip or change fluoxetine doses in order to drink unless your prescriber specifically tells you to change the medication. Fluoxetine and its active metabolite remain in the body for an extended period, so missing one dose does not remove the potential for an alcohol-medication interaction [1]. Stopping fluoxetine abruptly can also cause discontinuation symptoms in some people. Talk with your healthcare provider about how much and how often you drink so the medication and alcohol use can be addressed safely.
What Is the Medication Used to Treat Alcoholism?
Three are approved in the United States: naltrexone, which reduces the urge to drink; acamprosate, which eases the discomfort of abstinence; and disulfiram, which causes unpleasant symptoms if alcohol is consumed [3]. They are prescribed alongside counseling and, where depression or anxiety is present, alongside an antidepressant such as Prozac.
Finding Help in Minnesota
If depression treatment is not working as expected and alcohol use is also present, both deserve a careful assessment. Alcohol can worsen mood, reduce antidepressant response, and interfere with treatment adherence, while depression can also complicate recovery from AUD [2]. Northwoods Haven’s intensive outpatient program provides treatment for alcohol use disorder when IOP is an appropriate level of care and can address co-occurring mental health needs, with coordination or referral for medication management and medically supervised withdrawal when needed. Reach out for a confidential assessment and help determining the appropriate next step.
