What It Is:
Trazodone is a prescription antidepressant with sedative properties used in cats to manage anxiety, stress, and certain behavioral issues, as well as to calm cats during veterinary visits or travel. It belongs to the serotonin antagonist and reuptake inhibitor (SARI) class and works by modulating serotonin levels in the brain.
Trazodone is not FDA approved for cats, but is widely used off label under veterinary guidance.
🐾 What It Treats and Why It’s Used
Trazodone may be prescribed for:
- Situational anxiety, such as travel, thunderstorms, or fireworks
- Veterinary visit or grooming sedation to reduce stress and facilitate handling
- Generalized anxiety or fear-based behaviors
- Postoperative confinement to keep cats calm and reduce self-trauma
- Noise phobia and storm anxiety
It is often used in combination with behavioral modification and environmental enrichment.
🧪 How It Works
Trazodone modulates serotonin activity by:
- Blocking serotonin 5-HT₂A receptors to reduce anxiety
- Inhibiting serotonin reuptake to increase availability in the synaptic cleft
- Blocking certain histamine and alpha-adrenergic receptors, contributing to its calming effect
This multi-modal action produces sedation and anxiolysis without the heavy sedation associated with some other drugs.
🐾 Dosage and Administration
Key administration guidelines:
- Typically given once or twice daily depending on the situation
- Oral tablets can be scored or compounded into a liquid for precise dosing
- Start with a low dose and adjust under veterinary supervision based on effect and tolerance
- Give with or without food, though food may reduce mild gastrointestinal upset
For pre-visit or situational use, trazodone is often given one to two hours before the stressful event.
🔍 Side Effects and Precautions
Trazodone is generally well tolerated, but possible side effects include:
- Sedation or lethargy, especially at higher doses
- Gastrointestinal upset, such as vomiting or diarrhea
- Ataxia or wobbliness in some cats
- Hypersalivation or drooling
- Paradoxical agitation or excitability in rare cases
Use with caution in cats with:
- Preexisting cardiac disease or arrhythmias
- Liver or kidney impairment (may require dose adjustment)
- Concurrent use of other serotonergic drugs (risk of serotonin syndrome)
Never combine with MAO inhibitors, other SSRIs, or tramadol without veterinary guidance.
🩺 Prognosis
When used appropriately:
- Situational dosing provides predictable calming for short-term stressors
- Chronic dosing for generalized anxiety may require gradual dose adjustment and monitoring
- Combination with behavior modification improves long-term outcomes
Regular follow-up ensures effective dosing and minimizes side effects.
💡 Cat Owner Note
Trazodone can be a game changer for cats who dread vet visits, thunderstorms, or moving day. It helps them stay calmer without total sedation, making both you and your cat more comfortable. Always follow your vet’s dosing instructions and monitor your cat’s response to find the right balance.
