### Safety and Recommendations

Flea and tick treatments are regulated by both the FDA and EPA, ensuring the safety and effectiveness of prescription and over-the-counter products. Despite this, some pets may experience mild side effects, from transient skin irritation to more serious issues in those with specific sensitivities. Always consult your veterinarian for advice tailored to your pet’s health and local parasite prevalence.
