My insurance company would pay for it after 55, so when I talked to my doctor he gave me a prescription. When I was at the pharmacist filling out the disclaimer papers the pharmacy had, I noticed it had neomycin base. My luck, I've had reactions to neomycin so she said I had to talk to my doctor before she would give me the shot. Bottom line I can't have the shot. Really worries me that I'll get shingles, but I'm not willing to risk it.
