Endoparasites in Ball Pythons

Reptile · Python regius · typical adult weight 1.00–2.00 kg

5 cited drugs treat Endoparasites in ball pythons: Fenbendazole, Mebendazole, Praziquantel, Pyrantel Pamoate, Thiabendazole.

Gastrointestinal helminth and protozoal infections. Macrocyclic lactones, benzimidazoles, and pyrantel cover the bulk of nematode treatment; protozoal indications require dedicated drugs (metronidazole, sulfadimethoxine).

The overview above describes Endoparasites across species; the citations below are the ExoticRx dose rules scoped to ball pythons — a reference list, not new species-specific clinical guidance.
