What People Say About Dr. Nancy Mozelsio, MD
Was prescribed allergy medication and took it with positive results for a year and a half. Pharmacy tried to refill prescription, received no response from doctor's office for over a month. Called to check on status and was told a nurse would get back to me to let me know what was going on. No call received. Called back a week later and was told that the prescription had not been refilled because I needed to see the doctor again. No explanation ever provided on why this was never communicated.
