I feel like I am being a turd when I say it, but I never write anything for friends or family...
I turned down signing a sports physical for my friends son this past week.
I just tell them I do not write scripts for anyone but patients I see in the ED; if questioned; I tell them there is always a possiblity of side effects and such and there could be problem if we do not have documentation. I have never been pressed much more than that on the matter and my friends know just not to ask.
I wrote my wife 'Penicillin' actually for me once when I tested Strep positive in the back room at work; and I called in Macrobid when her OB had wrote a script for it but my wife traveled to her work and could not find it.
I have seen other friends write for virtually anything for anyone...
I think the key is to have one policy and stick with it.. otherwise, if you write for one person and not the other, feelings get hurt...
