Summary and essential information

Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) used in clinical practice to raise serotonin levels in the brain. By reducing serotonin reuptake at nerve endings it can improve depressed mood, help with anxiety and panic, and reduce obsessive thoughts or compulsive behaviours.

In the UK this medicine is commonly supplied as fluoxetine hydrochloride in tablet, capsule and liquid forms. Typical strengths seen in primary care include 10 mg and tablets of 20 mg strength and an oral solution such as 20 mg per 5 ml.

• Drug family: SSRI (selective serotonin reuptake inhibitor)
• Common formulations: 10 mg and tablets carrying a 20 mg dose, capsules, and oral solution
• Usual onset: some early change in 1-3 weeks; full effect often takes several weeks

Conditions for which fluoxetine is prescribed

Healthcare professionals may offer fluoxetine for a range of mental health diagnoses in adults and, in selected situations, in younger people. The decision to prescribe is individual and depends on clinical judgement and patient history.

• Obsessive-compulsive disorder (OCD) (OCD)
• The anxiety disorder called panic disorder
• Major depressive disorder in clinical terms
• Bulimia nervosa, a binge-purge eating disorder (often requires higher doses, sometimes up to 60 mg per day)
• Premenstrual dysphoric disorder: a mood related condition also called PMDD

If you are uncertain why fluoxetine has been recommended for you, ask your GP, mental health team or pharmacist to explain the intended benefit.

How to use this product it, dosing and what to expect

Always follow the prescriber's directions. Do not stop treatment suddenly without consulting the clinician because abrupt cessation can trigger withdrawal-type symptoms.

• Take tablets or capsules whole unless the label indicates they can be split; do not crush extended-release products.
• Most patients take fluoxetine once daily; some find morning dosing reduces sleep disturbance.
• Improvements may be noticed in 1 to 4 weeks, with maximum benefit often appearing after 6 to 8 weeks or longer.
• If stopping treatment, clinicians usually recommend a gradual reduction where appropriate to reduce discontinuation effects.

Protective measures and key safety checks

Before you go forward, your prescriber should review your medical history, family psychiatric history and current medicines. Important issues to flag include:

• History of bipolar disorder, previous manic or hypomanic episodes
• Epilepsy or any history of seizures
• Severe liver dysfunction or urinary retention problems
• Glaucoma or raised intraocular pressure
• Recent substance misuse, prior suicidal thoughts or self-harm
• Plans for or recent electroconvulsive therapy (ECT)

Pregnancy through lactation need an individual risk-benefit discussion in a session with your clinician. Late exposure to SSRIs in pregnancy can rarely affect newborn infants; if breastfeeding, monitor the baby for sleep or feeding changes.

Avoid heavy alcohol use while taking fluoxetine as alcohol can increase sedation and impair recovery of mood.

Contraindicated situations and MAOI sequencing rules

Do not take fluoxetine if you have a known allergy to it or to any ingredient in the preparation. Certain drug combinations are contraindicated because of serious engagement and communication related risks.

• Do not intermingle fluoxetine with pimozide or thioridazine.
• Do not use fluoxetine together with monoamine oxidase inhibitors (MAOIs) such as phenelzine or tranylcypromine.
• Disclose all medicines, including over-the-counter products and herbal remedies, before starting fluoxetine.

Timing notes to reduce interpersonal engagement risk: wait at least 14 days after stopping an MAOI before initiating fluoxetine. After stopping fluoxetine, allow a minimum of 5 weeks before starting an MAOI or thioridazine.

Undesired effects, warning signs and urgent actions

Many undesired consequences are mild and settle with time, but some require immediate medical evaluation.

Seek emergency care if you notice signs of a severe allergic reaction such as:

• Swelling in the mouth region including lips, tongue, and throat, or widespread hives
• Severe breathing difficulty

Other serious symptoms that need prompt assessment include:

• Sudden, severe eye pain, changes in vision or seeing halos
• A fast heartbeat with an irregular rhythm, fainting, collapse or severe shortness of breath
• Confusion, slurred speech, seizures or a severe new throbbing head pain (may indicate low sodium)
• High fever with muscle rigidity, agitation or profuse sweating (possible serotonin syndrome or neuroleptic malignant syndrome)

Serotonin syndrome is an emergency. Typical features include agitation, hallucinations, very high temperature, muscle stiffness, loss of coordination, very rapid heartbeat and severe nausea, vomiting or diarrhea. If these occur seek urgent medical help.

Common, usually transient treatment side effects can include:

• Unrefreshing sleep, vivid dreams, pain of the heads or dizziness
• Tremor and temporary increases in anxiety
• Parched oral cavity, increased sweating, tiredness or yawning
• Gastrointestinal symptoms such as nausea, reduced appetite, vomiting or diarrhea
• Disorder of sexual function including reduced libido or difficulties with ejaculation or orgasm

If lingering effects continue or become troublesome, contact your prescriber or local pharmacist for advice.

Give your clinician a full list of all prescribed medicines, non-prescription drugs and supplements.

• Drugs that raise serotonin levels: other SSRIs, SNRIs, certain tricyclics, some opioids like tramadol, and St John’s wort
• Medications affecting heart rhythm or the QT interval
• Anticoagulants and antiplatelet agents such as warfarin and some direct oral anticoagulants
• Certain antimicrobials, antifungals, HIV treatments, antimalarials and some cancer drugs
• Migraine triptans (for example sumatriptan)
• Some stimulant medicines for ADHD and selected antipsychotics
• Nonsteroidal anti-inflammatory medications including ibuprofen and naproxen, which may increase bleeding risk
