What is the meaning of fluoxetine?
Fluoxetine is an SSRI antidepressant that is usually prescribed by clinicians for mood and anxiety-related disorders. It is widely available as a generic medication in the United States; the original brand name was Prozac. By altering serotonin availability between nerve cells, fluoxetine can reduce symptoms associated with depression, certain anxiety disorders, obsessive thinking, and premenstrual mood disturbances.
Approved applications
The U.S. Food and Drug Administration has approved fluoxetine for several clinical symptoms, including:
- Clinical term: major depressive disorder
- OCD, standing for obsessive-compulsive disorder
- Panic disorder, an anxiety disorder
- Bulimia nervosa, a chronic eating disorder
- Premenstrual dysphoric disorder mentioned as PMDD, a severe form of premenstrual syndrome
PMDD is a significant womens health indication where fluoxetine has demonstrated benefit for mood and physical symptoms in the luteal phase of the menstrual cycle.
The mode by which it acts
Fluoxetine works primarily by inhibiting the reuptake of serotonin in presynaptic neurons, increasing serotonin availability in the synaptic cleft. This modulation of serotonergic signaling can improve mood, reduce anxiety, and decrease compulsive behaviors. Fluoxetine has a relatively long elimination period: the parent drug has an approximate half-life of 2 to 4 days and its major active metabolite, norfluoxetine, persists longer, often 7 to 15 days. The long half-life can smooth withdrawal effects but can also prolong ill effects after discontinuation.
Administration of dosing
- Adhere to the prescriber directions without deviation. Do not alter the dose or stop treatment suddenly without consulting the prescriber.
- Swallow delayed-release or weekly formulations whole. Do not crush, break, or open those capsules.
- Initial adult doses commonly start at 10 mg or 20 mg once daily, depending on the condition plus the patient profile. Clinicians may titrate the dose based on clinical response and tolerability.
- Some patients transition from daily dosing to a 90 mg delayed-release capsule taken once weekly after achieving steady control with daily therapy.
- Although the drug has a long half-life, gradual tapering is still recommended when discontinuing to reduce the chance of withdrawal or discontinuation symptoms.
If you need to stop taking fluoxetine, ask your prescriber for a planned taper rather than stopping abruptly.
Cautions and safety alert notices
- Inform your clinician about existing conditions such as liver impairment, diabetes, seizure disorders, narrow-angle glaucoma, urinary retention or prostate enlargement, bipolar disorder or past manic episodes, and prior substance use problems.
- Prenatal to lactation care: discuss uncertain risks and benefits together with your clinician. Use late in pregnancy can be associated with neonatal adaptation syndromes; infants exposed via breast milk should be monitored.
- Antidepressants may raise the risk of suicidal thinking and behavior in children, adolescents, and young adults. Monitor for changes in mood, behavior, or suicidal ideation, particularly during treatment initiation and dose changes.
- Beverages containing alcohol can amplify sedation or cognitive impairment and is best limited while taking fluoxetine.
- Individuals predisposed to angle-closure glaucoma may experience eye symptoms; seek immediate care for sudden eye pain or vision changes.
Report any new or worsening agitation, unusual behavior, increased anxiety, hostility, severe insomnia, or thoughts of self-harm to your prescriber without delay.
Cautions and when this treatment should not be used that require attention
- Known allergy to fluoxetine or any inactive ingredient in the product.
- Avoid use with pimozide or thioridazine.
- Do not start fluoxetine within 14 days of stopping a monoamine oxidase inhibitor (MAOI). After stopping fluoxetine, wait at least 5 weeks before initiating an MAOI or thioridazine.
- Exercise caution and consult your prescriber before using linezolid or intravenous methylene blue because of serotonin syndrome risk.
Likely peripheral effects
Seek medical assistance promptly if you experience troubling symptoms. signs of a serious allergic reaction such as hives, swelling of the face or throat, difficulty breathing, or widespread blistering rash.
Contact your clinician right away for symptoms that may indicate a serious reaction:
- Signs of serotonin syndrome: restlessness, hallucinations, high fever, excessive sweating, shivering, rapid heartbeat, muscle rigidity or twitching, poor coordination, severe nausea, vomiting, or diarrhea
- Severe neurologic reaction: high fever with rigid muscles, confusion, irregular heartbeat, fainting
- Vision problems or acute eye pain
- Poor coordination, severe weakness, or confusion that might indicate low sodium (hyponatremia)
- New or worsening cardiac symptoms such as pronounced palpitations or lightheadedness
More frequent, usually milder effects that often lessen over time include:
- Changes in sleep such as insomnia or vivid dreams, or another routely fatigue
- Cephalalgic pain, dizziness, tremor, or increased nervousness
- Gastrointestinal complaints including nausea, upset stomach, diarrhea, or dry mouth
- Alterations in appetite and weight
- Upper respiratory type symptoms such as nasal congestion or sore throat
- Sexual adverse health effects including lower libido, delayed orgasm, or erectile difficulties
Drugs and supplements the back and forth of communication guidance
- Combining fluoxetine with other serotonergic agents increases the risk of serotonin syndrome. Examples include other antidepressants, tramadol, certain opioids, linezolid, intravenous methylene blue, triptans, St. John's wort, and tryptophan products.
- Concurrent use with NSAIDs or anticoagulants may raise bleeding risk; examples include aspirin, ibuprofen, naproxen, celecoxib, and warfarin. The monitoring process may be required.
- Central nervous system depressants such as benzodiazepines, opioids, some sleep aids, muscle relaxants, and certain anticonvulsants can add to sedation or impair coordination.
- Fluoxetine inhibits CYP2D6 and can increase blood levels of drugs metabolized by this enzyme. This mutual interaction can affect some tricyclic antidepressants, certain antipsychotics, beta-blockers like metoprolol, and may reduce tamoxifen activation.
- Certain antiarrhythmics and some antipsychotics may increase QT interval risk when combined with fluoxetine.
Always give your prescriber and pharmacist a complete list of prescription medicines, over-the-counter products, vitamins, and herbal supplements before starting fluoxetine.
What to do after missing your dose
- If you miss a daily dose, take it as soon as you remember unless the next scheduled dose is near; do not double the dose to catch up.
- For the 90 mg once-weekly delayed-release capsule, take the missed weekly dose as soon as possible if it is within a few days of the usual day; otherwise skip and take the next dose on the regular day. Ask your prescriber for clarification if you are uncertain.
