Hi, my daughter had ear infection and tonsillitis beginning of January and we were prescribed 10 days of pen v. Two weeks later after finishing antibiotics and white spots are back and she’s poorly. We’ve been given 5 days of amoxicillin but another doctor said 10 days of pen v should be prescribed. I had already started the amoxicillin at this point though. Has amoxicillin worked for anyone’s child and was it a 5 or 7 day course? I originally thought it was good we were given amoxicillin as we had pen v before and the tonsillitis returned.
