Key Takeaways on Sileo

Key Takeaways on Sileo

Sileo, with its active ingredient dexmedetomidine, is a specialized prescription medication designed to address anxiety in dogs. It is particularly effective for situations involving noise aversion.

Sileo's Purpose

Sileo is primarily used to treat anxiety in dogs, especially when they face intense moments such as thunderstorms or fireworks. Many pet owners have reported that Sileo helps their dogs manage these stressful situations (Source 2).

Sileo's Mechanism of Action

Sileo works by calming the dog through its active ingredient, dexmedetomidine. This ingredient temporarily blocks the release of adrenaline-like chemicals in the brain. This interaction on certain receptors helps to induce calmness without necessarily causing drowsiness (Source 1, Source 2).

Prescription Only Medication

It is crucial to understand that Sileo should only be administered under the guidance of a veterinarian. You cannot administer Sileo to your dog without having consulted a veterinarian (Source 2).

Optimal Timing for Administration

For maximal results, Sileo must be used correctly. Pet owners should administer Sileo approximately 30-60 minutes before an anticipated anxiety-inducing event, such as a thunderstorm or fireworks display.

Repeat Dosing Guidelines

If anxiety returns after the initial dose, Sileo can be re-dosed. However, it is imperative to consult your veterinarian for specific instructions regarding the frequency and maximum daily doses to ensure your dog's safety and well-being.

Sileo Administration Checklist

Sileo Administration Checklist

Proper administration of Sileo is essential for its effectiveness and your dog's safety. Following a clear checklist can help ensure correct usage.

Veterinary Consultation is Mandatory

Before administering Sileo, always discuss its use and the appropriate dosage with your veterinarian. They will determine if Sileo is suitable for your dog and provide a specific dosing chart based on your dog's weight (Source 2).

Accurate Dosing with Oral Syringe

Sileo comes with a special oral syringe designed for precise dosing. It is very important to use this syringe to ensure the correct amount of medication is given. The normal dosage administered is typically 1-3 mcg per kilogram of body weight (Source 2).

Correct Oral Mucosa Application

Sileo should be administered between the dog's cheek and gum, specifically onto the oral mucosa. It is not meant to be swallowed directly. This method allows for proper absorption of the medication.

Observe Your Dog's Response

After administering Sileo, closely monitor your dog's reaction to the medication. Observe for signs of calmness or any potential side effects.

Proper Storage Instructions

Store Sileo as directed by your veterinarian or the product label. This typically involves keeping it at room temperature and out of reach of children and pets.

Risks & When to See a Vet

While Sileo is generally safe when used as directed, it's important to be aware of potential risks and know when to seek veterinary attention.

Sedation and Drowsiness

Although Sileo is designed to induce calmness without necessarily causing drowsiness, some dogs may experience mild sedation or drowsiness. This is a possible side effect.

Gastrointestinal Issues

Possible side effects can include vomiting or diarrhea. If these symptoms are severe or persistent, contact your veterinarian.

Bradycardia (Slow Heart Rate)

A less common but possible side effect is bradycardia, which is a slow heart rate. Your veterinarian will consider your dog's overall health before prescribing Sileo.

Overdose Concerns

An overdose of Sileo can lead to more severe symptoms. These may include excessive sedation, a significantly low heart rate, and low blood pressure. It is critical to adhere strictly to the prescribed dosage.

When to Contact Your Veterinarian

  • Excessive Sedation: If your dog appears excessively sedated or unresponsive after receiving Sileo, contact your vet immediately.
  • Severe Side Effects: If any side effects, such as vomiting, diarrhea, or changes in heart rate, are severe or persist, seek veterinary advice.
  • Lack of Effectiveness: If Sileo does not seem effective at the prescribed dose, do not increase the dose yourself. Instead, consult your veterinarian to discuss alternatives or adjustments.
  • General Concerns: For any concerns about your dog's reaction to the medication, it is always best to contact your veterinarian.
