Abortion is a sterile operation, and if it is done in a public hospital above the second grade, sterilization is very strict when doing this operation, so there is generally no need to apply anti-inflammatory drugs, that is, cephalosporins, after abortion. Because of the abuse of cephalosporin anti-inflammatory drugs, it may cause dysbiosis. However, if the environment of abortion is not very good, usually there may be mild inflammation or overdue abortion, these may cause post-abortion infection, need to take oral cephalosporin anti-inflammatory drugs to prevent post-abortion sense. Generally eat 3-5 days can be, if the inflammation is more obvious, need to eat more than 7 days.
