Terryann Bernard, 49, of Wading River, is facing four felony and four misdemeanor counts of possession of a forged instrument and possession of stolen property.
Authorities say the prescriptions were usually for OxyContin and were filled more than 100 times over a 2 1/2 year period. Police say most were also submitted to her insurance company for reimbursement.
Typically, just one such legal prescription is dispensed for a one month period, according to authorities. But they say Bernard obtained as many as three in one week.
