The cost of Prostap and Zoldex injections has cropped up a number of times over the years. Opinions differ about this but the point to remember is that the cost of these drugs may be different depending on where the drugs are bought and the size of the GP Group which is making the purchase. In other words this may be described as a market place as is the case for other drugs etc.
The starting point for me is the information published by NICE about drug prices which you can see from the links below.

Prostap is priced at £75.24 for the 3.75 mg monthly injection and £225.72 for the 11.25 mg 3 monthly injection.

Zoladex is priced at £65.00 for the 3.6 mg monthly injection and £235.00 for the 10.8 mg 3 monthly injection.
I understand the cost of Prostap and Zoladex etc comes out of CCG budgets for GP Practices. There is not much difference in the cost of these published figures between Prostap and Zoladex but in practice, as for most things, market influences kick in and costs can change. I was told by a GP Practice Manger some time ago that their practice pays £185 for the 3 month Prostap injection. As mentioned, a reduction in the cost of drugs takes into account the size of the GP Practice and no doubt how much business the Practice has with their supplier. Presumably similar reductions are available for Zoladex and other drugs and medical supplies.
I don’t think the costs influence consultants too much when they decide whether to start a man on Prostap or Zoladex. I think the clinical experience of consultants in the first place governs, for the most part, whether a man is given Prostap or Zoladex. There may be circumstances when a man’s preference may be taken into account.
My first injection was Zoladex many years ago and my GP suggested switching to Prostap for my second injection and this was agreed by my hospital Oncology Team. I have no idea how many GPs switch a man from one drug to the other without speaking first to the hospital oncology team. I would never be happy with that.
I hope this is useful.
