prescribe

I am a Junior Doctor at a Hospital in the UK. and as such, I have to prescribe the usual medicines for the patients on the ward, moreover, and not very occasionally, I get asked to prescribe Alcoholic drinks for patient, especially for elderly patients who are used to take it every night for example. and some times at special occasions e.g. Christmass. I have managed to so far to avoid presrcibing such drinks by asking my colleages to do so. But I know that oen time I wont be able to ask a colleage for one reason or the other. So I wonder what's the Fiqh's stance on this issue, and what is the best course of action for me.thanks and may Allah bless you all.
