Until September 3, every federally cleared option against New World screwworm in pets could only treat an infestation that had already started. Now there is one that can prevent it.
The Food and Drug Administration issued an Emergency Use Authorization for Capstar tablets and revised an existing authorization for generic nitenpyram tablets, clearing both for prevention as well as treatment of New World screwworm infestations in dogs, puppies, cats and kittens. The animals must weigh at least two pounds and be at least four weeks old. The generic tablets were authorized in June for treatment only.
