What are the side effects of Tessie? A guide for dog owners

3 min read

According to product information from the European Medicines Agency, very common side effects associated with the veterinary drug Tessie (tasipimidine) in dogs include tiredness (lethargy) and vomiting. This medication is used for short-term alleviation of situational anxiety in canines, and it is vital for pet owners to understand what are the side effects of Tessie before administration.

Quick Summary

Tessie, a drug containing tasipimidine for canine anxiety, primarily causes very common side effects such as lethargy and vomiting, along with common reactions like drowsiness, diarrhea, and behavioral changes. Serious effects like decreased heart rate, blood pressure, and body temperature can also occur. The medication is contraindicated in dogs with severe systemic disease or pre-existing sedation.

Key Points

  • Very Common Side Effects: The most frequently observed side effects are lethargy (tiredness/sluggishness) and vomiting.

  • Common Side Effects: Other common reactions include drowsiness, diarrhea, uncoordinated movements (ataxia), behavioral changes, and reduced appetite.

  • Physiological Impact: Tessie can cause a dose-dependent decrease in heart rate, blood pressure, and body temperature.

  • Contraindications: The medication should not be used in dogs with severe heart, liver, or kidney disease, or if they are already sedated.

  • Human Safety: Accidental human exposure can lead to drowsiness, decreased heart rate, and lower blood pressure, requiring immediate medical attention.

  • Overdose Risk: A high overdose is potentially life-threatening due to CNS depression and an increased risk of aspiration pneumonia.

Understanding Tessie and its Active Ingredient

Tessie is a veterinary medicinal product prescribed for dogs to provide short-term relief from situational anxiety and fear, such as during fireworks or owner departure. Its active ingredient is tasipimidine, a potent and selective alpha-2A adrenoceptor agonist. This mechanism of action works by inhibiting the release of noradrenaline in the brain, which in turn counteracts the physiological arousal associated with fear and anxiety in canines.

Potential Side Effects of Tessie

Side effects of Tessie vary in frequency and severity. It is crucial for pet owners to be aware of these potential reactions and consult with their veterinarian if concerns arise.

Very Common Side Effects

Clinical trials indicate that the most frequently observed side effects, occurring in more than 1 in 10 treated dogs, are lethargy and vomiting.

Common Side Effects

Common side effects, affecting between 1 and 10 animals per 100 treated, include drowsiness, behavioral changes, gastrointestinal issues such as diarrhea and loss of appetite, uncoordinated movements (ataxia), urinary incontinence, paleness of mucous membranes, excessive thirst, low white blood cell count (leucopenia), and hypersensitivity reactions.

Less Frequent and Serious Effects

Less commonly, more serious effects have been noted. These include a decrease in heart rate (bradycardia), blood pressure (hypotension), and occasionally respiration rate. A drop in body temperature can also occur, necessitating that treated dogs be kept in a suitable ambient temperature. Higher doses can lead to dose-dependent QT prolongation, a cardiac effect, and in cases of high overdose, the risk of aspirating vomit is increased due to central nervous system depression.

Drug Interactions and Contraindications

Owners should be aware of conditions and other medications that may affect the safe use of Tessie.

Contraindications

Tessie should not be used in dogs with known hypersensitivity to its ingredients, those with moderate to severe renal, liver, or cardiovascular disease, or dogs already exhibiting sedation. Its safety has not been established for pregnant or lactating dogs.

Drug Interactions

Concurrent use with other central nervous system depressants may enhance Tessie's sedative effects. If used alongside tricyclic antidepressants or serotonin reuptake inhibitors, a dose reduction of Tessie is recommended.

What to Do in Case of Overdose

An overdose of Tessie can be serious. If an overdose is suspected, contact your veterinarian immediately. Observe your dog for severe drowsiness or uncoordinated movements. Be mindful of the risk of aspiration if vomiting occurs.

How Tessie Compares to Other Sedatives

Understanding how Tessie compares to other sedatives can help in discussions with your vet about the best treatment option.

Precautions for Human Exposure

Accidental human exposure to tasipimidine can cause drowsiness, decreased heart rate, and lowered blood pressure. Avoid ingestion and skin contact. In case of accidental exposure, seek immediate medical advice and show the product leaflet. Do not drive.

Conclusion: Monitoring Your Pet

Being informed about the potential side effects of Tessie is vital for pet owners. Close monitoring of your dog and open communication with your veterinarian about any observed symptoms are crucial for ensuring safe and effective treatment of anxiety.

Always consult with your veterinary surgeon before administering Tessie or any other medication to your dog.

Frequently Asked Questions

No, Tessie (tasipimidine) is a veterinary medicinal product intended exclusively for dogs to treat situational anxiety.

Vomiting is a very common side effect. You should still maintain the minimum recommended interval of at least 3 hours between doses. If your dog appears drowsy, a dose reduction may be necessary, but this should only be implemented following veterinary advice.

While intended to alleviate anxiety, some dogs may experience paradoxical behavioral changes, such as barking, avoidance behavior, disorientation, or increased reactivity. This is a common side effect.

If the dose is too high, your dog may appear overly drowsy, have uncoordinated movements (ataxia), or respond to you abnormally slowly. If these signs are observed, the subsequent dose should be reduced as per your veterinarian's guidance.

You must inform your veterinarian of any other medications your dog is taking. The effects of Tessie can be potentiated by other central nervous system depressants. If used with certain antidepressants, such as fluoxetine or clomipramine, the Tessie dose must be reduced.

To prevent accidental ingestion or skin contact, store the medication safely out of reach of children. If skin contact occurs, wash the area immediately. In case of accidental ingestion, seek immediate medical advice.

Tessie is intended for short-term use, typically for up to 9 consecutive days, and should not be used for chronic conditions without a veterinarian's explicit instruction.
