What Happens When You Give Your Dog Trazodone?

Behavioral Changes

Depending on the reason for prescribing Trazodone, you may observe changes in your dog’s behavior. This could include a reduction in aggressive tendencies or a decrease in excessive barking.

What Does Trazodone Do To Dogs?

Trazodone is a medication commonly used in veterinary medicine to address behavioral issues and anxiety in dogs. Trazodone hydrochloride is the active ingredient in Trazodone. It belongs to a class of drugs known as serotonin receptor antagonists and reuptake inhibitors (SARIs). So it’s not the same as monoamine oxidase inhibitors.

Trazodone works by increasing serotonin in the brain, which results in calmness and better mood. Vets prescribe Trazodone for various purposes, including:

  • It can relieve anxiety: It’s often prescribed to help dogs cope with anxiety-inducing situations, such as thunderstorms, fireworks, noise phobia, or separation anxiety.
  • Behavioral Disorders: This reuptake inhibitor can calm dogs and address problematic behaviors such as excessive barking, aggression, or destructive behavior.
  • Sedation: The mild sedative properties of Trazodone make it useful in calming dogs for situations like vet visits, grooming, or travel.

Trazodone modulates serotonin levels by blocking serotonin reuptake and antagonizing certain serotonin receptors. This leads to increased serotonin availability, which can have a calming effect and help regulate mood.

How is Trazadone Given?

Trazodone Dosage and Administration

Trazodone for dogs is typically administered orally in the form of tablets or capsules. This medication is also available in liquid form. Additionally, this serotonin antagonist can be given on an empty stomach, depending on your vet’s recommendations. Some dogs may experience mild gastrointestinal upset, and giving the medication with food can help minimize this.

How Much Trazodone Can You Give a Dog?

The appropriate dosage of Trazodone for a dog is determined by a veterinarian based on several factors, including dog weight, health status, and the specific reason for prescribing the medication. Dosages can vary widely, so it’s crucial to follow your vet’s instructions carefully.

As a general guideline, this reuptake inhibitor is often prescribed in the range of 2 to 5 mg per pound of body weight. However, this is a rough estimate, and your veterinarian will provide you with the precise dosage for your dog’s needs.

Never attempt to determine the dosage yourself, as giving too much Trazodone or too little can have adverse effects. Always consult your veterinarian for professional advice tailored to your dog’s requirements.

What is the Most Common Side Effect of Trazodone?

The most common side effect of Trazodone in dogs is sedation. Dogs may become drowsy or sleepy after taking the medication. While this sedative effect is often desirable in situations where calming is needed, it’s important to monitor your dog for side effects.

Trazodone can cause:

  • Gastrointestinal Upset: Some dogs may experience mild gastrointestinal issues, such as twitching, nausea, or vomiting.
  • Incoordination: In rare cases, dogs may exhibit signs of incoordination or instability.
  • Too Much Sedation or Lethargy: While mild sedation is expected, excessive lethargy or weakness could be a sign of an adverse reaction.

Serious possible side effects include serotonin syndrome (a reaction that happens if serotonin levels in the brain get too high). In other words, giving your dog too much Trazodone or other serotonergic drugs can cause serotonin syndrome.

Signs of Trazodone overdose include high body temperature or high blood pressure, elevated heart rate, difficulty breathing, tremors/shivering, dilated pupils, etc.

IMPORTANT NOTE: Severe serotonin syndrome is a potentially life-threatening condition if not treated. So, if you notice any of the symptoms above, visit the nearest vet clinic immediately.

It’s crucial to use this effective medication under the guidance of a veterinarian, and any concerns about side effects should be promptly discussed with them. They can adjust the dosage or recommend alternative approaches based on your dog’s response.

Is 50mg of Trazodone a Lot for a Dog?

A 50mg dose of Trazodone can be considered too much for certain dogs based on factors such as their size, weight, and overall health. Dogs vary widely in their sensitivity to medications, and what might be an appropriate dose for one dog could be excessive for another. Here’s a list of scenarios in which a 50mg dose might be too much:

  • Small Breed Dogs: Smaller dogs generally require lower doses of medications due to their size. A 50mg dose might be excessive for a very small dog.
  • Sensitivity: Some dogs are more sensitive to medications than others. A 50mg dose could be too much for a dog that is particularly sensitive to the effects of Trazodone.
  • Health Conditions: Dogs with certain health conditions, such as liver or kidney issues, may metabolize medications differently. In such cases, a lower dose might be recommended.
  • Drug Interactions: If a dog is taking other medications that interact with Trazodone, the combined effect could be stronger, making 50mg too much.

Always follow the guidance of your veterinarian, who will consider your dog’s specific characteristics and needs.
