Paroxetine Tablets: Selective Serotonin Reuptake Inhibitor (SSRI)

Paroxetine is a Selective Serotonin Reuptake Inhibitor (SSRI) used to address various behavioural disorders in companion animals. While originally approved for human use (commonly known by the brand name Paxil®), it is utilised in veterinary medicine on an extra-label basis for dogs and cats. By increasing the levels of serotonin in the brain, paroxetine helps to regulate mood and emotional responses. It is particularly valued by veterinarians for treating anxiety-based conditions that have not responded to other medications in the same class.

Prescription Required

Paroxetine is a prescription-only medication. A valid prescription from a licensed veterinarian is required for purchase. Professional veterinary oversight is essential, as this medication typically requires several weeks of consistent dosing to achieve full therapeutic benefit. Paroxetine must be used strictly as part of a veterinarian-guided treatment plan and should never be discontinued abruptly; a specific tapering schedule is necessary to safely decrease the dosage.
