Comtan (generic:entacapone) really works for me in extending my on-times for carbidopa-levadopa to the point where I am almost symptom free some days. However, I have been paying $300-$400 for it per month because my insurance, and I've been told, most insurance didn't cover it. Well, IT DOES NOW and I'm paying $5 a month at CVS. Thought I'd pass that along. My doctor didn't know about it.
(FYI: I'm male, 58, dx in 2004, take 10 sinemet @ 25/100 and 2.5 comtan @ 200mg in five daily doses, plus selegiine, amantadine, and sinimet er.)
