Hi Dee,
I wouldn't worry too much about your dad going past his due date for his Zoladex, I know it is not ideal, in an ideal world his surgery would have been up to speed, however I doubt a few days or even a week is likely to have a profound effect on his treatment.
I was on Zoladex for 3 years, and when I came off I was looking forward to getting my testosterone levels up to speed, however it took best part of 12 months for me to work the side effects of the Zoladex out of my system. Now I know I was on it a lot longer than your dad, but I would think it will take more than a few days for his body to resume making testosterone in damaging quantities.
Also, I haven't seen much posted on here recently, but there are many who advocate what they call Intermittent Hormone therapy, the theory being that it is just as good to have a occassional bouts of HT followed by a break.
So far as Doctors surgeries are concerned, they all have their local inconsistencies, for example it seems to be left to me to organise a PSA test about a week before each appopintment with a Consultant. I have found that I need to book that appointment 2 perhaps 3 weeks in advance, because often the phlebotomist is booked solid that far in advance.
Then when I phone for the result, irrespective of which receptionist answers my call, they all tell me 'the result was normal', I have to ask them for the number. I have been repeating this rigmarole at least 4 times a year for the last 8 years, and it is tedious, but by the same token life is too short to get too worked up about it?
Ditto with Zoladex and Prostrap, my Surgery has an in-house Pharmacy, but the receptionists do not cross reference, so when I book an appointment with the nurse for a Zoladex implant, I then need to make a second phone call to the Pharmacy, tell them my appointment date and ensure they have a zoladex implant for me. Crazy when you think that the receptionist and pharmacist sit no more than 10 feet apart, but that is the way it is, and it is easier to go with the flow, learn the system, learn the tricks and make the system work for you?
