OB/GYN NP

Hello all! I was wondering if any of you (probably Derm office nurses see this most) have had any experience with administering Botox injections? If so, where did you get training, have you ever seen any nasty complications, and who in your office administers it (Docs, Rn's)? We're thinking of offering this as a treatment in our office, and I'm doing the research for getting this up-and-running. I've done searches on Botox, but all that comes up is patient info and advertisements for Doc's offices that provide this as a service. I've been unable to locate any educational classes about it for health care providers. Thanks in advance for any info you can give me!
