Good responses all. Premarin vag cream is sometime used intranasally due to it's vasoconstrictive properties for chronic nose bleeds or nasal sores. Beleive it...or not. The MOA I'm a little shady on, but you could very well see a prescription come across your bench of Premarin vag cream intranasally. (Of course, it never hurts to call for clarification if you are unsure.)
