The Pharmacist’s Take By · Clinical pharmacist · Written

Fluoxetine (Prozac) is an SSRI antidepressant that keeps nerve cells from reabsorbing serotonin, a brain chemical tied to mood, and treats depression, OCD, bulimia nervosa and panic disorder; one of the first SSRIs, on the market since about 1987 and available as a generic, it remains a common first choice. Most people tolerate it well, though nausea, headache, trouble sleeping and jitteriness are common early on. It carries a boxed warning for suicidal thoughts and behavior in children, teens and young adults up to 24, so watch closely for worsening mood in the first months and after any dose change. Do not stop it suddenly.

Clinical pearls

  • Take it in the morning, with or without food, since it tends to be energizing and can interfere with sleep.
  • Never combine it with MAOI antidepressants, pimozide or thioridazine, and allow five weeks after stopping fluoxetine before starting an MAOI.
  • Tramadol, triptans for migraine, other antidepressants and St. John's Wort raise serotonin syndrome risk, so check with your pharmacist first.
  • On warfarin, expect extra blood clotting checks when fluoxetine starts or stops, and report unusual bruising or black stools.
⚠️ FDA Boxed Warning — the FDA’s strongest safety alert ▾

Antidepressants, including fluoxetine, can increase suicidal thoughts and behavior in children, teens and young adults (up to age 24). This was seen in short-term studies. Adults over 24 did not have a higher risk, and risk was lower in adults 65 and older.

Anyone starting an antidepressant should be watched closely for worsening mood or new suicidal thoughts, especially in the first few months and after dose changes. Families and caregivers should watch for agitation, irritability and unusual behavior changes and tell the prescriber right away. Fluoxetine is not approved for children under 7. When used with olanzapine, also see the Symbyax boxed warning.

Patient information guide A plain-language walkthrough of Fluoxetine, written from its FDA label.

What Fluoxetine is used for

▾

Fluoxetine is used for several conditions, depending on the product.

  • Major depressive disorder (adults and children 8 to 18 for most products)
  • Obsessive compulsive disorder (adults and children 7 to 17 for most products)
  • Bulimia nervosa (binge-eating and vomiting behaviors) in adults
  • Panic disorder, with or without agoraphobia, in adults
  • Fluoxetine delayed-release capsules: labeled for major depressive disorder
  • Prozac and fluoxetine capsules, with olanzapine: depressive episodes with Bipolar I Disorder and treatment resistant depression (fluoxetine alone is not approved for these)

How Fluoxetine works

▾

Fluoxetine is an SSRI. It blocks the reuptake (recycling) of serotonin by nerve cells in the brain. This is believed to be linked to its effects, though the exact mechanism is unknown.

Fluoxetine dosage

▾

Fluoxetine is taken by mouth as capsules, delayed-release capsules, tablets or oral solution. It is usually taken once daily in the morning, and higher doses may be split into morning and noon. It can be taken with or without food.

Doses are adjusted over several weeks. Follow your prescriber and your product label, and ask your pharmacist what to do if you miss a dose.

2 DOSAGE AND ADMINISTRATION This product is only available in a 60 mg dosage form. A 30 mg dose may be achieved with one-half of the scored tablet. Use of this product requires initial titration with another fluoxetine product according to the dosing guidelines indicated below. Use another fluoxetine product for initial doses of 10 to 20 mg/day or for doses other than 30 mg or 60 mg: Indication Adult Pediatric MDD (2.1) 20 mg/day in morning (initial dose) 20 mg/day (target dose) 80 mg/day (maximum dose studied) 10 to 20 mg/day (initial dose)* *This product has not been studied in doses greater than 20 mg/day in pediatric MDD. OCD (2.2) 20 mg/day in morning (initial dose) 20 to 60 mg/day (target dose) 10 mg/day (initial dose) 10 to 60 mg/day (target dose) Bulimia Nervosa (2.3) 60 mg/day in morning – Panic Disorder (2.4) 10 mg/day (initial dose) 20 mg/day (target dose) 60 mg/day (maximum dose studied) – No additional benefits seen at higher doses above 20 mg/day in MDD (2.1, 14.1) Use a lower or less frequent dosage in patients with hepatic impairment, the elderly, and for patients with concurrent disease or on multiple concomitant medications (2.5, 8.6) 2.1 Major Depressive Disorder Initial Treatment Adult —Initiate fluoxetine tablets 20 mg/day orally in the morning. Consider a dose increase after several weeks if insufficient clinical improvement is observed. Administer doses above 20 mg/day once daily in the morning or twice daily (i.e., morning and noon). The maximum fluoxetine tablets dose should not exceed 80 mg/day. In controlled trials used to support the efficacy of fluoxetine tablets, patients were administered morning doses ranging from 20 to 80 mg/day. Studies comparing fluoxetine tablets 20, 40, and 60 mg/day to placebo indicate that 20 mg/day is sufficient to obtain a satisfactory response in MDD in most cases [see Clinical Studies (14.1)]. Pediatric (children and adolescents) —Treatment should be initiated with a dose of 10 or 20 mg/day. After 1 week at 10 mg/day, the dose should be increased to 20 mg/day. However, due to higher plasma levels in lower weight children, the starting and target dose in this group may be 10 mg/day. A dose increase to 20 mg/day may be considered after several weeks if insufficient clinical improvement is observed.

Fluoxetine warnings and precautions

▾
  • Suicidal thoughts and behavior in children, teens and young adults (boxed warning).
  • Serotonin syndrome, a potentially life-threatening reaction.
  • Allergic reactions and rash.
  • Mania or hypomania, especially in people at risk for bipolar disorder.
  • Seizures, bleeding, low sodium and angle-closure glaucoma.
  • QT prolongation and heart rhythm problems.
  • Weight loss and sexual dysfunction.
  • Long half-life: dose changes take weeks to be fully reflected.

Fluoxetine interactions

▾

Fluoxetine interacts with many medicines.

  • MAOIs, linezolid and intravenous methylene blue: serotonin syndrome risk; contraindicated.
  • Pimozide and thioridazine: QT risk; contraindicated.
  • Other serotonergic drugs (SSRIs, SNRIs, triptans, tramadol, St. John's Wort): higher serotonin syndrome risk.
  • NSAIDs, aspirin, warfarin: more bleeding.
  • CYP2D6 drugs such as tricyclic antidepressants: higher levels of those drugs.
  • Diazepam, alprazolam, haloperidol, clozapine, phenytoin, carbamazepine: levels may rise.
  • Lithium: levels may change.

Interactions listed in the FDA-approved label

From the Fluoxetine prescribing information (“Drug Interactions”): what the manufacturer studied or reported to the FDA.

  • Pimozide: Fluoxetine can increase the level of pimozide through inhibition of CYP2D6, and both can prolong the QT interval. Concomitant use is contraindicated.
  • Thioridazine: Risk of QT prolongation and elevated thioridazine levels because fluoxetine inhibits CYP2D6. Do not administer with fluoxetine or within a minimum of 5 weeks after fluoxetine has been discontinued.
  • Other serotonergic drugs (other SSRIs, SNRIs, triptans, TCAs, opioids, lithium, buspirone, amphetamines, tryptophan, St. John's Wort): Concomitant use increases the risk of serotonin syndrome. Monitor for signs and symptoms of serotonin syndrome, particularly during initiation and dosage increases; if it occurs, consider discontinuing fluoxetine and/or the serotonergic drugs.
  • Tricyclic antidepressants (TCAs): Plasma levels of imipramine and desipramine increased greater than 2- to 10-fold with fluoxetine, and this may persist for 3 weeks or longer after fluoxetine is discontinued. The TCA dose may need to be reduced and plasma TCA concentrations monitored temporarily when co-administered or recently discontinued.
  • NSAIDs, aspirin, warfarin (drugs that interfere with hemostasis): Concurrent use may potentiate the risk of bleeding; altered anticoagulant effects including increased bleeding have been reported with warfarin. Carefully monitor patients receiving warfarin when fluoxetine is initiated or discontinued.
  • Benzodiazepines (diazepam, alprazolam): Diazepam half-life may be prolonged; alprazolam plasma concentrations increase, causing further psychomotor performance decrement.
  • Antipsychotics (haloperidol, clozapine): Elevation of blood levels of haloperidol and clozapine has been observed with concomitant fluoxetine.
  • Anticonvulsants (phenytoin, carbamazepine): Elevated plasma anticonvulsant concentrations and clinical anticonvulsant toxicity developed after starting fluoxetine.
  • Lithium: Both increased and decreased lithium levels have been reported, along with cases of lithium toxicity and increased serotonergic effects. Monitor lithium levels when administered concomitantly.
  • Drugs metabolized by CYP2D6: Fluoxetine inhibits CYP2D6, making individuals with normal activity resemble poor metabolizers. Approach with caution; start narrow therapeutic index drugs at the low end of the dose range if the patient is taking fluoxetine or took it in the previous 5 weeks; consider a decreased dose of the original medication.

7 DRUG INTERACTIONS As with all drugs, the potential for interaction by a variety of mechanisms (e.g., pharmacodynamic, pharmacokinetic drug inhibition or enhancement, etc.) is a possibility. Drugs Metabolized by CYP2D6: Fluoxetine is a potent inhibitor of CYP2D6 enzyme pathway (7.6) Tricyclic Antidepressants (TCAs): Monitor TCA levels during co-administration with fluoxetine or when fluoxetine has been recently discontinued (5.2, 7.6) Benzodiazepines: Diazepam—increased t½, alprazolam—further psychomotor performance decrement due to increased levels (7.6) Antipsychotics: Potential for elevation of haloperidol and clozapine levels (7.6) Anticonvulsants: Potential for elevated phenytoin and carbamazepine levels and clinical anticonvulsant toxicity (7.6) Serotonergic Drugs: (2.6, 2.7, 4.1, 5.2) Drugs that Prolong the QT Interval: Do not use fluoxetine with thioridazine or pimozide. Use with caution in combination with other drugs that prolong the QT interval (4.2, 5.11, 7.6, 7.7) 7.1 Monoamine Oxidase Inhibitors (MAOIs) [See Dosage and Administration (2.6, 2.7), Contraindications (4.1), and Warnings and Precautions (5.2)]. 7.2 CNS Acting Drugs Caution is advised if the concomitant administration of fluoxetine and such drugs is required. In evaluating individual cases, consideration should be given to using lower initial doses of the concomitantly administered drugs, using conservative titration schedules, and monitoring of clinical status [see Clinical Pharmacology (12.3)]. 7.3 Other Serotonergic Drugs The concomitant use of serotonergic drugs (including other SSRIs, SNRIs, triptans, tricyclic antidepressants, opioids, lithium, buspirone, amphetamines, tryptophan, and St. John's Wort) with fluoxetine increases the risk of serotonin syndrome. Monitor patients for signs and symptoms of serotonin syndrome, particularly during treatment initiation and dosage increases.

Before taking Fluoxetine

▾
  • Tell your prescriber about bipolar disorder, seizures, liver disease, glaucoma or heart rhythm problems.
  • Children: approved only for major depressive disorder and OCD; not for children under 7.
  • Pregnancy: later use may affect the newborn, including breathing problems and persistent pulmonary hypertension.
  • Older adults and people on many medicines may need lower or less frequent dosing.
  • Do not take with MAOIs, pimozide or thioridazine.

Fluoxetine overdose

▾

Overdose can cause seizures (sometimes delayed), altered mental status including coma, serious heart rhythm problems and cardiac arrest, high blood pressure, and serotonin syndrome. Call Poison Control at 1-800-221-2222 or seek emergency care right away. Activated charcoal may be considered if treated early.

What Fluoxetine does in the body

▾

Fluoxetine blocks serotonin uptake into human platelets and is much more potent at blocking serotonin than norepinephrine uptake in animal studies. It binds much less strongly than older tricyclic antidepressants to receptors linked to sedation and anticholinergic effects.

How your body processes Fluoxetine

▾

Peak levels occur around 6 to 8 hours after a dose. Food may delay absorption slightly but does not meaningfully change how much is absorbed. Fluoxetine is broken down by the liver into an active metabolite called norfluoxetine and cleared by the kidneys.

It is eliminated slowly. The half-life is 4 to 6 days for fluoxetine with ongoing use, and 4 to 16 days for norfluoxetine. The drug can stay in the body for weeks after stopping.

How to store Fluoxetine

▾

Store at 20° to 25°C (68° to 77°F); excursions permitted to 15° to 30°C (59° to 86°F) .

Fluoxetine: pharmacist answers to common questions

Quick, plain-English answers to the questions patients ask most about Fluoxetine — the kind of thing our pharmacy team would talk through with you at the counter.

What is fluoxetine for?

▾
Fluoxetine is an SSRI antidepressant. Most products treat major depressive disorder, OCD, bulimia nervosa and panic disorder. Some products, like the delayed-release capsules, are labeled only for depression, so check your own product with me.

How should I take it?

▾
Take it by mouth, usually once a day in the morning, with or without food. Follow the directions on your label. Don't stop suddenly without talking to your prescriber.

What side effects should I expect?

▾
Common ones are nausea, headache, trouble sleeping, nervousness, diarrhea, dry mouth, sleepiness and sweating. Sexual side effects can also happen. Call your doctor if they bother you or don't ease.

When should I call my doctor right away?

▾
Call for new or worse depression, suicidal thoughts, agitation or unusual behavior changes, especially early on or after dose changes. Also get help for a rash, unusual bleeding, fever with stiff muscles and fast heartbeat, seizures or fainting.

What medicines should I avoid with it?

▾
Never take it with MAOIs, pimozide or thioridazine. Be careful with other serotonin-raising drugs like triptans, tramadol and St. John's Wort. Tell me if you take blood thinners, aspirin or NSAIDs, since bleeding risk goes up.

Is it safe in pregnancy?

▾
SSRI use, especially later in pregnancy, may cause breathing and other problems in newborns. Talk with your prescriber before changing anything if you're pregnant or planning to be.

Is Fluoxetine available over the counter?

▾
No. Fluoxetine is a prescription medicine: every Fluoxetine product listed with the FDA is prescription only, so it is not sold over the counter. Your prescriber decides whether it is appropriate for you, and your pharmacist dispenses it.

When was Fluoxetine first available?

▾
The earliest FDA record we hold for Fluoxetine is from 1987: its first approval in Drugs@FDA or its earliest product listing in the NDC Directory, whichever is older. Many older medicines were in use before their first formal FDA approval, so this is the earliest date on record, not necessarily when Fluoxetine was first used.

Who makes Fluoxetine?

▾
55 companies currently list Fluoxetine products in the FDA's NDC Directory, including Bryant Ranch Prepack, A-S Medication Solutions, Aurobindo Pharma Limited. That count includes repackagers and distributors as well as manufacturers (companies that sell only the raw ingredient are not counted), so fewer companies actually make it; the label on your bottle names the one that supplied yours.

Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.

A general popularity signal; it excludes Medicare, commercial insurance and cash prescriptions, so it is not total U.S. use. Based on the 137 of 844 listed Fluoxetine NDCs with Medicaid activity.

Compare Fluoxetine products

A representative set of FDA-listed product records for Fluoxetine — across manufacturers, strengths, and dosage forms, grouped by form with each product’s manufacturer and how the FDA approved it. The same medicine may be made and packaged by different companies, so a single drug can have many directory entries. (It’s also why a refill can look different — a new shape, color, or box — even though it contains the same medication.)

Fluoxetine side effects reported to the FDA (FAERS)

After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Fluoxetine — a signal of what to watch for, not proof the drug caused it.

The effects most often named in FDA reports that mention Fluoxetine are nausea, fatigue, headache; about 71% of the reports were classed as serious. These are voluntary reports, so they show what people report, not how often it happens.

Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Fluoxetine in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.

Fluoxetine recall history

A recall is when a specific batch of a medicine is pulled from the market — usually a manufacturing issue, not a problem with the drug itself. Class I is most serious, Class III least.

The FDA’s enforcement reports list one Fluoxetine recall since July 2021, covering 2 product listings. It is no longer listed as ongoing. A recall names specific lots from one company, so check the lot number on your own bottle rather than assuming every product is affected; your pharmacist can check whether your supply came from an affected lot.

💵 What Fluoxetine costs pharmacies (NADAC benchmark)

The national average invoice price pharmacies pay for the drug itself, from CMS's NADAC survey (data as of Sep 30, 2026). This is a supply-cost benchmark — not a retail price and not what you'd pay at the counter.

FormStrengthPharmacy acquisition benchmark
Capsule · Oral 40 mg $0.052 per capsule NDC details & price history
Tablet, Film Coated · Oral 10 mg $0.070 per tablet NDC details & price history
Tablet, Film Coated · Oral 20 mg $0.084 per tablet NDC details & price history

Solution · Oral 20 mg/5 mL $0.214 per mL NDC details & price history
Why show this? Your out-of-pocket cost depends on insurance, pharmacy markup, and discounts — but the acquisition benchmark tells you whether the medication itself is inexpensive or costly, which strengths cost more per dose, and whether a cash-price quote is in a reasonable range. Each row links to the NDC-level record with its full price history.
