Ahh...

Yah I wasn't too sure if would work, or could work with a reptile due to the difference in the physiology from a reptile and a mammal.

Perhaps a call to the vet? Sometimes even non-specialists will assist in emergencies (Most vets have access to another vet, or survice that advise them) and they may have a chemical that is recommend for Frogs that the vet may have access too. You may be able to work so you just pay for the treatment... or it could even be something you could pick up and bring home... It never hurts to ask!
