Is Fluoxetine (Prozac) safe for dogs and cats?
Moderate risk for petsFluoxetine (Reconcile® is FDA-veterinary-approved for canine separation anxiety) is the only SSRI with a veterinary FDA approval; despite this, accidental ingestion of human formulations at human therapeutic doses is a frequent ASPCA APCC call and can cause serotonin syndrome in dogs. Veterinary use: Reconcile 1–2 mg/kg/day for canine separation anxiety; combined with behavioral modification. Serotonin syndrome: the primary toxicity in dogs — signs include hyperthermia, tremors, vocalization, mydriasis, hyperreflexia, ataxia, hypersalivation; typically begins within 4–6 hours of ingestion. Toxic dose: clinical signs reported in dogs at doses >1.7 mg/kg; moderate symptoms at 5–10 mg/kg; severe symptoms at >10 mg/kg. Treatment: decontamination if recent ingestion; cyproheptadine (serotonin antagonist) 1.1 mg/kg PO/PR for serotonin syndrome; methocarbamol for tremors; IV fluids; thermoregulation. Long half-life: norfluoxetine's extended half-life means signs may persist 24–72 hours; extended monitoring required. Concurrent medications: dogs on MAOIs (selegiline for cognitive dysfunction), tramadol, or trazodone have enhanced serotonin syndrome risk.
