Never heard of Novira. I'm in the UK so most stuff is free. Trouble is the only med that works for me is the L-dopa. I've tried all the off time meds (Ropinirole, opicapone, entacapone, etc etc) with little to no effect.
However a recent prescription for Clonazapam has really helped with my rigidity, and in turn with my sleep, mood and anxiety.
I started at 0.25mg per day, but only really noticed it working at 0.5mg.
My husband has started a 2 week free trial of the Neupro patch which is supposed to help with off periods since it is a 24 hour slow release. I have no idea what it will cost if he does continue with the drug.
Have a good day.
So happy for you.
