Pharyngitis - streptococcal; Streptococcal pharyngitis
Most sore throats are caused by viruses, not strep-related bacteria. Strep cannot be accurately diagnosed by symptoms or a physical exam alone. Many of the other causes of sore throats may have the same symptoms.
Sore throats should only be treated with antibiotics if the strep test is positive. Antibiotics are taken to prevent rare but more serious health problems, such as rheumatic fever.
Penicillin or amoxicillin is usually first tried. Antibiotics should be taken for 10 days, even though symptoms are usually gone after few days.
The following tips may help your sore throat feel better:
Symptoms of strep throat usually get better in about 1 week. Untreated, strep can lead to serious complications.
On rare occasions, strep throat can lead to rheumatic fever if it is not treated. Strep throat may also cause a rare kidney complication called post-streptococcal glomerulonephritis.
Call if you develop the symptoms of strep throat. Also, call if you are being treated for strep throat and are not feeling better within 24 - 48 hours.
