which antibiotic would you recommend if a person seems to have pneumonia? had cough for 3/4 weeks, chills, fever, body ache.. cough was bad two weeks ago and reduced considerably. already took augmentin but didn t seem to work since the phlegm is till yellow/green. now wheezing also sometimes. Don t have any other symptoms now other than postnasal drip and cough with phlegm and wheezing. Is levafloxacin too strong for something like this?
