I am about to start Diflucan for the infection. But I have a great deal of the Amoxicillin left to take. Do I finish the Amoxicillin? The dentist who prescribed the Amoxicillin has not prescribed anything else for the infection, she says get in as soon as possible for the tooth to be extracted. I am trying but my appt isn't until Nov because of my insurance (long story). She says that is the best antibiotic for the infection. I have never experienced a professional never prescribing another RX when they find out a patient has a reaction to the first. I thought the main purpose was to get the infection out?
