Fluoxetine Capsules: Selective Serotonin Reuptake Inhibitor (SSRI)

Fluoxetine is a Selective Serotonin Reuptake Inhibitor (SSRI) commonly used to treat various behavioural disorders. While originally approved for human use (well-known by the brand name Prozac®), it is frequently prescribed in veterinary medicine on an extra-label basis for dogs and cats. It works by increasing the levels of serotonin in the brain, which helps to stabilise mood and reduce anxiety. Fluoxetine is often a cornerstone of a comprehensive behavioural modification plan for pets struggling with chronic fear or compulsive 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 this medication can take several weeks to reach full therapeutic effect. It must be used strictly as directed, and the medication should never be stopped abruptly; a veterinarian will provide a specific tapering schedule if the medication needs to be discontinued to ensure the pet's neurochemical balance remains stable.
