A Threat to Cats and Other Animals

A dangerous parasite, the New World screwworm, has been a growing concern for cats and other animals. The larvae of this fly can burrow into open wounds, causing serious harm.

FDA's Significant Decision

Recently, the U.S. Food and Drug Administration (FDA) took a major step by allowing the emergency use of a drug called Credelio CAT. Originally approved for fleas and ticks, this drug can now help fight this parasitic threat.

  • First-Time Clearance: This is the first time a drug has been specifically cleared for this use in cats and kittens.
  • Prescription-Only: The drug will only be available with a prescription, ensuring that a licensed veterinarian can monitor any side effects.
  • Professional Expertise: The FDA emphasizes the importance of professional expertise in managing this treatment.

Risk Assessment and Prevention

  • Low Risk for Most Cats: Most cats in the U.S. are at low risk. The parasite is more common near the U.S.-Mexico border and in countries where it is prevalent.
  • Higher Risk for Outdoor Cats: Outdoor cats and those that have traveled to affected areas are more likely to be exposed.
  • Consult Your Veterinarian: Cat owners should talk to their veterinarians to decide if this treatment is right for their pets.

Potential Side Effects

Credelio CAT's active ingredient, lotilaner, is part of a widely used class of drugs. While generally safe, it can have side effects. Some cats may experience:

  • Nervous system issues
  • Tremors
  • Unsteady movement
  • Seizures

Pet owners should be aware of these potential risks.

Conclusion

The FDA's emergency authorization highlights the seriousness of the New World screwworm threat and the importance of having effective treatments available. Cat owners should stay informed and work closely with their veterinarians to ensure the best care for their pets.
