how long before amoxicillin starts working
Amoxicillin usually starts working in 24-72 hours showing some improvements if the organism is susceptible to amoxicillin. For me it will work with on 24 hours.inus infections can take from a couple of weeks to a month for antibiotics to clear up. It takes the drugs a long time to get into all that pus in your sinuses and to have an effect.
