I was poking around purely out of curiosity, and ran into www.drugdelivery.ca. I don’t need any drugs (and I’m Canadian anyway), but decided to look around to see what was available.
I clicked the “Prescription Drugs” tab, and lo and behold under the “Shop for medications by disease”, I found Rabies!! I didn’t know you could take antihistamines to treat rabies. I bet quite a few doctors don’t know that as well. 
Apparently anaphylactic shock can be treated with eye drops.
