One type of sore throat that can be treated is strep throat, which is caused by bacteria. Your provider will probably do a "rapid strep test" to make sure it's strep rather than a cold or another virus-induced sore throat.   The group A Streptococcus bacteria that causes strep throat can be killed by antibiotics. The only thing they will work on is bacteria. Sore throats caused by viruses are not affected by them. To treat strep throat, providers usually prescribe penicillin or amoxicillin (Amoxil). These antibiotics are the best choices due to their safety, affordability, and effectiveness against strep bacteria. Antibiotics are also effective at stopping the further transmission of strep throat, and patients should cease to be contagious shortly after beginning treatment.    Strep throat treatment is available at Invara Pharmacy+Clinic.
