Endoparasites in African Grey Parrots

Bird · Psittacus erithacus · typical adult weight 0.40–0.65 kg

8 cited drugs treat Endoparasites in african grey parrots: Fenbendazole, Ivermectin, Levamisole, Mebendazole, Oxfendazole, 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 african grey parrots — a reference list, not new species-specific clinical guidance.
