The most common side effects for statins are muscle pains and raised liver
enzymes. There are other rare side effects but to date, no studies have shown any significant increase in cardiovascular or kidney
problems with these drugs. So you can be rest assured about that. As far as continuing the hormone injections are concerned, you have to take them for life or when the PSA starts rising, whichever is earlier. However, there is an alternative as these injections are expensive. You can undergo a small operation under local anaesthesia called bilateral orchidectomy, in which both your testes are removed. This has essentially the same effect as taking these injections, infact much more reliable. Also it is a one time thing and cheaper in the long run.
