my husband has been taking the above hormone drug for sixteen months every four weeks as an injection, when he was first diagnosed with prostate cancer stage four his psa was 544 when he went in October last year it had gone down to 0.33 which we are very grateful for and it is being kept contained at the moment, he suffers very bad mood swings on the night he has the injection in the morning, where he has terrible mood swings and is not himself at all, he does go back to his normal self but also gets may be three or four more shortened sessions of the mood swings in the next couple of weeks, we are going to see his oncologist in a couple of weeks time, does anyone else have knowledge of this................he does not realise at the time it is happening and has no real memory of it the next day. Thank you
