Mastitis is seen in lactating women and is treated mainly with anti-inflammatory drugs if no breast abscess has formed. The common bacteria that cause mastitis are Staphylococcus aureus and gram-positive cocci, so anti-inflammatory needles are mainly used for antibiotics that are more sensitive to these bacteria, and if you are not allergic you can use penicillin, such as melocillin or cephalosporin anti-inflammatory drugs, such as cefazolin and ceftazidime, which are more sensitive to mastitis and do not affect breastfeeding. If mastitis has formed a breast abscess, the use of anti-inflammatory drugs alone is not enough, you need to carry out surgical treatment, abscess incision and drainage, extraction of pus for bacterial culture, according to the results of bacterial culture, and then use sensitive anti-inflammatory antibiotics anti-infection, anti-inflammatory treatment effect will be better.
