The number of days for anti-inflammatory injections is closely related to the purpose of use, the type of disease being treated, and the severity of the disease, and generally takes 3 days to 2 weeks. If it is to prevent infection, anti-inflammatory injections are usually given for 3 days. If it is to treat a disease, it is related to the type of disease and the severity of the disease, such as tonsillitis, fever caused by bacteria, pneumonia, etc., the course of treatment is usually about 1 week. Those with more serious symptoms, such as pelvic inflammatory disease, may take about 2 weeks. Some inflammatory diseases may develop into chronic inflammation or cause inflammation of surrounding organs and aggravate the condition if they are not treated thoroughly. Therefore, the use of antibiotics should generally be a full course and full amount, but not too long, otherwise it will easily cause bacterial resistance and reduce the effectiveness of the drug. In addition, patients also need to conduct skin tests before anti-inflammatory injections to avoid serious symptoms such as anaphylaxis, and they should be careful not to abuse antibiotics to avoid drug resistance.
