IV. Parasiticides



1. Dimetridazole (Emtryl). Can be used to treat amoebiasis at a dose of 40 mg/kg/day for 5 days. Safe and effective. Will also kill flagellates.



2. Fenbendazole (Panacur). A good parasiticide for intestinal nematodes. Can be given orally at a dose of 50-100 mg/kg and repeated in 2 weeks.



3. Ivermectin (Equvalan). Contraindicated for use in chelonian species. Turtles given low doses may become paretic in the hind limbs and deaths have been reported. Doses for snakes and lizards range from 200-400 micrograms/kg IM and repeated in 2 weeks. Will kill nematodes and may be effective against ticks and mites. USE CAUTION WITH THIS DRUG, EVEN IN SNAKES AND LIZARDS, SINCE THE KINETICS IN REPTILES HAVE NOT BEEN WELL STUDIED!



4. Levamisole phosphate (Ripercol). Works on the lungworm (Rhabdias) and on intestinal Strongyloides. Dose is 10 mg/kg intraperitoneally (intracoelomically) repeated in 2 weeks. Fenbendazole works well on Strongyloides too.



5. Metronidazole (Flagyl). Used on intestinal flagellates and for amoebiasis at a dose of 100-200 mg/kg PO, repeated in 2 weeks. A dose of 40-50 mg/kg PO should be used in colubrid snakes since there have been some problems with the higher doses in some species. There are reports that Flagyl works as an appetite stimulant in reptiles. This drug is also good for anaerobic bacterial infections. A recent pharmacokinetics report recommends a dose of 20 mg/kg PO Q 48 hours in yellow rat snakes (Kolmstetter et al. 2001).



6. Praziquantel (Droncit). Used to treat cestode and trematode parasites. Dose is 5-8 mg/kg IM or PO repeated in 2 weeks.



7. Sulfadimethoxine (Bactrovet, Albon). Efficacious in the treatment of coccidia. Dose is 90 mg/kg PO on day one and 45 mg/kg PO on 5 successive days. This drug may also be given IM or IV. Adequate hydration must be maintained.
