I picked it up at my "local" vets. They had it and Flagyl as well on hand in their pharmacy. I've been advised to let the Panacur work it's course before using Flagyl. I was at ANOTHER vets' again today (as advised to do by the last)since this one is a reptile specialist who does the zoo herps. She lanced Atchesons' eye to relieve pressure from swelling, gave an intravenous shot of antibiotic and supplied an antibiotic eye drop. While all this was going on, Hudson who was with me for a check-up passed another lump of tapeworm. Panacur works! Where do you hail from Sipedon? If you're south of the snow-line, providing an address may not help.
