... treatments (45 treatments) ending in December. On Dec. 30, he had the second injection of Eligard. He experienced times of mild confusion after the first injection. After the 2nd injection, he has experienced confusion on a daily basis. I called his urologist; but, he said that he doesn't think the Eligard is causing the confusion. My husband is 82 years old. Could the confusion be a side effect of the Eligard? Please help, we feel we are out there on our own
