Ritigotine patch

I am currently on Amantadine, Half SINIMET CR SINIMET and SINIMET plus. I have now been prescribed ritagotine patches and should be starting this week on 2mg patches for two weeks then if all ok to increase gradually. I am concerned because I hate taking something new and also it seems like a lot of medication as I have not been told to stop anything else.
Has anyone had similar or anything that may help.
Thank you.
