Hello, I went to the dentist on sept. 24 to have a filling repaired and I was informed that infection had set in and was prescribed amoxiccilin. the second day of taking the medicine I was coughing of dark green mucus and blowing greenish yellow stuff out of my nose. my condition is better but I still have those symptoms and I will be taking my last pill tonight. Should I refill the prescription and continue taking the med until it's gone?
