주의사항 및 금기

• Known hypersensitivity to fluoxetine
• Concurrent use of Monoamine Oxidase Inhibitors (MAOIs), including selegiline and amitraz (found in some tick collars)
• Patients with epilepsy or a history of seizures
• Concurrent use with drugs that lower the seizure threshold (e.g., acepromazine, chlorpromazine)
• Known sensitivity to fluoxetine or other SSRIs
• History of seizures or epilepsy
• - **Seizure Disorders:** Use is contraindicated in patients with a history of seizures. - **Diabetes Mellitus:** Use with caution as fluoxetine may alter blood glucose levels, necessitating insulin adjustments. - **Hepatic Impairment:** Dosages may need to be reduced in patients with severe liver disease due to decreased clearance. - **Tapering:** Because of the long half-life of the active metabolite (norfluoxetine), tapering off the drug is generally only necessary when a patient has been on the drug long-term (>8 weeks). - **Pregnancy/Nursing:** Safety is not fully established (FDA Category C in humans). Excreted in milk at 20-30% of plasma levels; use caution in nursing animals.

약물 상호작용

• BUSPIRONE: Increased risk for serotonin syndrome
• CYPROHEPTADINE: May decrease or reverse the effects of SSRIs (acts as a serotonin antagonist)
• DIAZEPAM, ALPRAZOLAM: Fluoxetine may increase diazepam and alprazolam plasma levels
• DIURETICS: Increased risk for hyponatremia
• INSULIN: May alter insulin requirements (can alter blood glucose)
• ISONIAZID: Increased risk for serotonin syndrome
• MAO INHIBITORS (e.g., amitraz, selegiline): High risk for serotonin syndrome; use contraindicated. A 5-week washout is required after stopping fluoxetine before starting an MAOI, and a 2-week washout if switching from an MAOI to fluoxetine.
• PENTAZOCINE: Serotonin syndrome-like adverse effects possible
• PHENYTOIN: Increased plasma levels of phenytoin possible
• PROPRANOLOL, METOPROLOL: Fluoxetine may increase these beta-blocker's plasma levels; atenolol may be safer to use
• TRAMADOL: SSRIs can inhibit the metabolism of tramadol to active metabolites, decreasing efficacy and increasing toxicity risk (serotonin syndrome, seizures)
