I had general question regarding applying medications.

For oral medications such as liquid flagyl (metronidazole) and panacur (febendazole), are they effective only if applied orally?

The instructions in the first aid article (http://www.frogforum.net/content.php...Frog-First-Aid) indicate flagyl and panacur to be applied topically on frog's back.

I have researched the posts and they argue for opposing views (should only be applied orally vs can be used topically and frog can absorb it).

Does anyone have firsthand experience with curing their frog(s) with topical application?

Thanks a lot in advance!!

Happy frogs.
