Hi! My Dad Has Parkinson's And Has Been Taking Carbidopa/levodopa

Hi! My Dad has Parkinson's and has been taking carbidopa/levodopa quite a while. He is having problems with increased sexual urges. This is also causing problems for female care givers and relatives (me and Mom), and a female resident. The caregiver's husband talked with Dad, but I am wondering is there a medication to decrease the urges but still help him with the problems of Parkinson's? I have left a message for his doctor's office to call back, but is there anything that may help? Thank You for Your help.
