Comparing the Safety of NexGard and Bravecto for Dogs
When choosing a flea and tick preventive for your dog, it’s important to consider both effectiveness and safety. Two of the most commonly prescribed oral treatments are NexGard and Bravecto. While both are backed by clinical trials and generally veterinarian-recommended, understanding their safety profiles, dosing schedules, and ingredients can help you make an informed decision under your vet’s guidance.
Safety and Effectiveness Overview
NexGard and Bravecto belong to a class of prescription oral medications known for combatting fleas and ticks effectively. Both products have undergone rigorous clinical testing to ensure their safety and efficacy for dogs when used as directed.
- NexGard: A monthly chewable tablet that kills adult fleas and ticks. NexGard Plus offers additional protection against heartworms and intestinal parasites.
- Bravecto: Available as a chew or a topical solution, this product provides up to 12 weeks of protection per dose, making it more convenient for some pet owners.
Key Safety Considerations
While both medications are generally safe, a few considerations help guide their use:
- Age and Weight Restrictions: Each product has a minimum age and weight limit. Ensure your dog meets these criteria to avoid adverse effects.
- Neurological Health: Dogs with a history of seizures or neurological issues may respond differently. Although uncommon, some pets may experience side effects like tremors or seizures, so consult a vet if your dog has predisposing conditions.
- Allergic Reactions and Sensitivities: Dogs can have individual sensitivities. If your pet has food allergies or drug responsiveness issues, monitor them closely, especially after the first dose.
Product Ingredients and Action
Understanding how these medications work can help clarify their safety and suitability:
- NexGard contains afoxolaner, an isoxazoline compound that affects the nervous system of fleas and ticks, killing them before they can transmit disease.
- Bravecto contains fluralaner, also an isoxazoline, which works similarly but offers longer-lasting action per dose.
Duration and Dosage
- NexGard: Administered monthly, allowing for quick discontinuation if side effects occur.
- Bravecto: Dosed every 12 weeks (8 weeks for certain tick species), which can be more convenient for recurring protection but stays in the system longer.
Usage Tips for Safety
For safe and effective use of either medication:
- Follow your veterinarian’s advice based on your dog’s health, age, and weight.
- Administer medication with food, as some dogs may tolerate it better.
- Observe your dog for side effects after initial and subsequent doses.
- If multiple dogs live in the household, ensure all are treated appropriately to prevent reinfestation.
When to Choose NexGard vs. Bravecto
- NexGard may be preferred for dogs with short-term flea or tick control needs or where monthly dosing allows for better monitoring of adverse reactions.
- Bravecto may be ideal for owners needing fewer doses or managing long-term infestations with less frequent administration.
Veterinary Consensus
Veterinarians generally favor both NexGard and Bravecto due to their proven track records. However, the decision often depends on:
- Your dog’s overall health status
- History of previous reactions to medications
- Specific parasite risks in your geographic location
- The convenience of dosing schedules and owner preference
Conclusion
Both NexGard and Bravecto are considered safe by veterinary professionals and regulatory authorities when used correctly. While NexGard’s monthly dosing may allow early detection of side effects, Bravecto’s extended coverage suits pet owners seeking longer protection intervals. Discuss your pet’s needs with your vet to choose the safest and most appropriate flea and tick solution.
