Conclusion
Moxidectin is preferred for long-lasting protection against internal and external parasites, including heartworms, and requires less frequent dosing. However, it may not be suitable for all dog breeds due to toxicity concerns.
Ivermectin has a broader application, including human use, and is effective against many parasites. However, it has potential neurological side effects, particularly in sensitive dog breeds.
Recommendation
- For animal use: Choose Moxidectin for long-term parasite control and heartworm prevention. Use Ivermectin with caution, especially in sensitive breeds.
- For human use: Ivermectin is approved for specific parasitic infections but should only be taken under medical supervision.
Always consult a veterinarian or healthcare professional before using any antiparasitic treatment.
