dentist prescribing benzaclin

I had a dentist trying to prescribe Benzaclin gel- I think pharmacists obligated professionally to ask more information if we think its not directly related to oral cavity to make sure its in the scope of their practice. I had a dentist get very rude with on asking for information. What do you guys think? Have you had such experiences? Or when would you think a dentist will prescribe benzaclin?
