Apo-Fluoxetine Oral Solution

Fluoxetine Oral Solution (20 mg/5 mL): SSRI for Behavioural Management

Fluoxetine is a Selective Serotonin Reuptake Inhibitor (SSRI) used to manage various anxiety-based and compulsive disorders. While this oral solution is originally approved for human use, it is frequently prescribed in veterinary medicine on an extra-label basis for dogs and cats. The liquid form is particularly useful for smaller pets or those that are difficult to pill, allowing for more precise dosing. It works by increasing serotonin levels in the brain to help stabilise mood and reduce anxiety-driven behaviours.

Prescription Required

Fluoxetine is a prescription-only medication. A valid prescription from a licensed veterinarian is required for purchase. Professional veterinary oversight is essential, as the medication typically takes four to six weeks to reach full therapeutic effect. It is important to follow the exact dosing schedule provided by your veterinarian. This medication must not be stopped suddenly; a gradual tapering process under professional guidance is required to safely discontinue use.
