Anti-inflammatory injections can be given during menstruation for pelvic inflammatory disease. Pelvic inflammatory disease refers to inflammation of the uterus, fallopian tubes and ovaries in women. No other treatment is usually taken during menstruation, mainly using antibiotics, such as oral cephalosporin or levofloxacin, along with tinidazole and metronidazole. Most pelvic inflammatory diseases occur in sexually active, menstruating women, and if unclean sanitary pads are used during menstruation or menstrual intercourse can cause pathogens to invade and cause an inflammatory reaction. It is best to choose the antibiotic based on the drug sensitivity test. The drug sensitivity test is done by taking the cervical secretion and doing the bacterial culture at the same time, in which case it takes several days of work in the laboratory to come up with the results. Therefore, the combination of broad-spectrum antimicrobials and anti-anaerobic drugs is usually chosen based on practical experience. The route of administration is generally faster with intravenous infusion, and the broad-spectrum antimicrobial agents are selected from second- and third-generation cephalosporins or quinolones, penicillins, tetracyclines, etc. Anti-anaerobic drugs are metronidazole, tinidazole or ornidazole. When treating with the above drugs, it is important to strictly grasp the principles of antibiotic treatment, such as empirical, broad-spectrum, timely and individualized principles.
