It is possible for strep throat to clear up without treatment; however, the risk of complications increases. Moreover, the infection is contagious until treated.
Penicillin and amoxicillin are typically prescribed to treat strep throat. For individuals with a penicillin allergy, newer generations of antibacterials may be used. These include cephalexin, erythromycin and azithromycin. All of these antibiotics kill strep bacteria, alleviate symptoms, and decrease the amount of time an individual is sick. Physicians may also recommend an over-the-counter pain and fever reducer.
Within 24 to 72 hours of beginning treatment, an individual is no longer contagious and he or she will begin to feel better. Still, all medication should be taken for the duration prescribed in order to prevent complications and bacterial resistance.
In addition to medication, individuals should rest from work and school, and avoid chemicals and environments that may further irritate the throat. Also, gargling warm salt water and eating soft and cold foods can soothe the throat.
