Understanding the Use of Antipsychotics in Cats
Psychotropic medications, including antipsychotics, are sometimes used in feline medicine to manage behavioral disorders and anxiety-related symptoms. However, their use must be approached with caution due to the risks of adverse effects and the lack of drugs specifically approved for cats.
What Are Antipsychotics?
Antipsychotic drugs are primarily developed for human psychiatric conditions such as schizophrenia and bipolar disorder. In veterinary settings, medications like acepromazine are occasionally used off-label for their sedative and tranquilizing effects. Although not true antipsychotics in the human sense, they are often referred to as such in veterinary contexts.
Veterinary Application in Cats
Veterinary use of antipsychotics in cats focuses on reducing anxiety, agitation, and hyperarousal during stressful situations like travel, grooming, or medical procedures.
Examples of Psychotropic Medications Used in Cats
- Acepromazine: A phenothiazine tranquilizer used for sedation but may cause paradoxical excitation in some cats.
 - Benzodiazepines (e.g., diazepam, alprazolam): Employed for situational anxiety; must be used carefully due to potential for hepatic side effects.
 - Buspirone: An azapirone anxiolytic often used for daily management of feline anxiety with fewer side effects than benzodiazepines.
 - SSRIs (e.g., fluoxetine, sertraline, paroxetine): Commonly prescribed antidepressants with benefits for long-term behavior management.
 - TCAs (e.g., clomipramine, amitriptyline): Used similarly to SSRIs but with more anticholinergic side effects.
 - Gabapentin: An anticonvulsant with anxiolytic properties, used preemptively for situational anxiety like veterinary visits.
 
Risks and Considerations
Use of psychotropic medications, especially antipsychotics, must consider the following factors:
- Side Effects: Vary by drug but may include sedation, paradoxical agitation, gastrointestinal upset, hepatic effects, and rarely seizures.
 - Off-Label Use: Many psychotropic drugs are not formally approved for feline use, requiring informed consent from pet owners.
 - Dosing and Monitoring: Medications need to be started at low doses and titrated based on efficacy and tolerance. Serum levels should be monitored for drugs like lithium.
 - Palatability and Delivery: Since many drugs are bitter, they may require compounding into flavored formulations or capsules to ensure feline compliance.
 - Drug Interactions: Veterinarians must assess concurrent medications to avoid adverse interactions, especially with central nervous system agents.
 
Symptoms of Overdose or Toxicity
Ingesting human psychiatric medications unintentionally can lead to toxicosis in cats. Symptoms include:
- CNS excitation or depression
 - Tremors or seizures
 - Cardiovascular abnormalities like tachycardia or hypertension
 - Anticholinergic effects in the case of tricyclic antidepressants
 - Serotonin syndrome with excessive serotonin activity
 
Behavioral Therapy Integration
Psychotropic medications are not curative. They are best used alongside behavioral modification strategies developed with veterinary behaviorists or trainers. Drugs help reduce arousal and enable more effective learning and behavior change.
When Are Antipsychotics Used in Cats?
Antipsychotics and related medications may be used in the following situations:
- Severe situational anxiety or aggression
 - Transport-related stress
 - Veterinary visits or hospital stays
 - Unmanageable stimuli like thunderstorms
 
Non-Pharmaceutical Alternatives
Some owners may prefer to explore nutraceuticals and supplements before pursuing pharmaceutical options. These include:
- Alpha-casozepine (Zylkene)
 - Probiotics (such as Purina Calm Care)
 - Serotonin precursors (in products like Solliquin)
 
The Role of the Veterinarian
A veterinarian's role includes evaluating behavioral issues in context—including environment, severity, and risk of harm—and deciding whether pharmacological support is warranted. Educating pet owners on drug use, side effects, alternatives, and monitoring schedules is critical.
Conclusion
Cats can indeed be prescribed certain antipsychotic or psychotropic drugs as part of a comprehensive behavior management plan. However, this must only occur under the guidance of a veterinary professional who can assess risks, monitor effects, and integrate behavior therapy for long-term success. Always consult your veterinarian before administering any new medication to your cat.
