Phenoxymethylpenicillin, also known as penicillin V (PcV) and penicillin VK, is an antibiotic useful for the treatment of a number of bacterial infections. [2] Specifically it is used for the treatment of strep throat, otitis media, and cellulitis. [2] It is also used to prevent rheumatic fever and to prevent infections following removal of the ...
If penicillin therapy fails, bacterial tonsillitis may respond to treatment effective against beta-lactamase producing bacteria such as clindamycin or amoxicillin-clavulanate. [37] Aerobic and anaerobic beta lactamase producing bacteria that reside in the tonsillar tissues can "shield" group A streptococcus from penicillins. [ 38 ]
Penicillin is actively excreted, and about 80% of a penicillin dose is cleared from the body within three to four hours of administration. Indeed, during the early penicillin era, the drug was so scarce and so highly valued that it became common to collect the urine from patients being treated, so that the penicillin in the urine could be ...
Often, tonsillitis will go away by itself, but depending on the type of infection, you may need to take a course of prescription antibiotics. In conversation with USA TODAY, an expert breaks down ...
Cefalexin is a useful alternative to penicillins in patients with penicillin intolerance. For example, penicillin is the treatment of choice for respiratory tract infections caused by Streptococcus, but cefalexin may be used as an alternative in penicillin-intolerant patients. [4]
Treatment with antibiotics shortens the duration of the acute illness by about 16 hours. [13] The primary reason for treatment with antibiotics is to reduce the risk of complications such as rheumatic fever and retropharyngeal abscesses. [13] Antibiotics prevent acute rheumatic fever if given within 9 days of the onset of symptoms. [16]
Unnecessary use of antibiotics could increase antibiotic-resistant infections, affect the digestive system, create allergic reactions, and other intense side effects. [21] A study published in JAMA found that narrow-spectrum antibiotics, such as amoxicillin, are just as effective as broad-spectrum alternatives for treating acute respiratory ...
It is not known whether antibiotics are effective for preventing recurrent sore throat. [14] There is only limited evidence that a hot drink can help alleviate a sore throat, and other common cold and influenza symptoms. [15] If the sore throat is unrelated to a cold and is caused by, for example, tonsillitis, a cold drink may be helpful. [16]
