If inflammation of the tonsils is mostly due to bacterial or viral infections, taking metronidazole may be useful if it is caused by anaerobic infections.
Tonsillitis is a common infectious disease, mainly caused by bacteria such as group A beta-hemolytic streptococcus, staphylococcus, or viral infections such as adenovirus and influenza virus. Metronidazole belongs to the nitroimidazole class of drugs, mainly for the treatment of anaerobic infections, so for bacterial and viral infections caused by inflammation of the tonsils, taking metronidazole is not useful.
However, in recent years, anaerobic bacterial infections have also been found, therefore, tonsillitis if anaerobic bacterial infections, generally speaking, eating metronidazole may be useful. If the patient has an allergy to the components of metronidazole, hepatic or renal hypoplasia, etc., it is prohibited to use the drug. Some patients may also experience adverse reactions such as nausea, vomiting and loss of appetite after using the drug.
In summary, when the tonsils are inflamed, patients need to go to the hospital in time, if necessary, need to follow the doctor’s instructions to use drugs, do not use metronidazole on their own.
