Hi Janet,
At various times in the past I have been on Zoladex and Prostrap, in all honesty I don't think that there is much to choose between them.
In some senses the so called 'side effects' aren't really side effects of the medication, they are the consequences of going without testosterone, which is after all the whole point of the treatment.
Personally I had lots of hot flushes, my body hair stopped growing and I didn't need to shave so often, over time I noticed muscle loss, and your other half will need to give some thought to a healthy diet, as weight gain is another common 'side effect'.
Libido, or rather the lack of it, is also a common problem. Anyone with PCa is entitled to Viagra, but I had to specifically ask my GP, it wasn't offered unless you asked. I found they worked for the first couple of months on Zoladex, but after that I was flogging a dead horse.
Some other chaps on this site seem to often have problems with their man boobs and sore nipples, but personally I didn't experience that.
For me Prostrap was easiest as it's given as a normal fluid injection in the arm, soreness persists for a day or two.
One of the problems with Zoladex is it is a pellet inserted into the abdomen, and the nurses don't seem to like to put them in the same place twice in a row. If your surgery is anything like mine, the nurses don't seem to keep a record of where they inserted the last one and rely on the patient to remember, so I got in the habit of following the seasons around my navel, in the winter inject above the navel, in the spring to the left, in the summer below the navel etc.
I used to have 3 monthly injections, technically they are 12 weekly, but it doesn't really matter if you are a week or two late. I used to get my PSA tested at the same time.
I have found it takes quite a while after the last injection before the effects wear off, I had my last jab 18 months ago and am only just noticing my body hairs growing back with vigour.
Good luck.
:)
Dave
