In general, men on ADT with LHRH drugs appreciate a holiday where they can be free of hot flashes and can recover their sex drive and the stamina they had before going on hormone therapy. But is intermittent ADT really better than continuous ADT in terms of the most serious side effects?
The authors found a relatively high incidence of serious adverse side effects in both patient populations. Patients on continuous ADT experienced a significant higher risk of heart failure and of breaking a bone than those on intermittent therapy.
