That's a very strange hormone therapy starting regime you've got there.
Degarelix is usually only used if it's urgent to get hormone therapy started quickly, or for patients with cardio issues. It doesn't require bicalutamide because it doesn't generate a Testosterone flare.
Prostap does generate a Testosterone flare when you start on it which is why bicalutamide is used. However, you can start on Degarelix for quick Testosterone suppression instead and then switch to Prostap, although I'm not quite sure what the switchover procedure is.
I would question what they're suggesting, because it's not normal as far as I know.
Degarelix does have the most significant injection site issues of the hormone therapy injections, but it's only the first dose which is 2 injections. If they continued you on it, the 4-weekly maintenance dose is one smaller injection.
