I Want To Contact The Company Who Makes Enablex Er

I want to contact the company who makes enablex er or the generic darifenacin er 15 mg. my copay cost is 259.00 for a 30 day supply. I am on a fixed income and have insurance but I cannot afford this price. Any chance I can get it cheaper from them. I really need this medication. Have tried different meds for several years and startng having problems again so my doctor said Enablex was a big improvement, which has worked for me. The generic is ok too but still too costly. Please help.
