You can take antipyretic drugs, such as ibuprofen, to reduce fever during the menstrual period, and you need to take more physical cooling, and then go to the hospital to improve the relevant examination to understand the specific causes and then carry out targeted treatment. The most common cause of fever in women in the puerperium is infection of the reproductive system, because the decrease in resistance of women in the puerperium and the discharge of vaginal dew can easily breed bacteria and other pathogenic bacteria, resulting in infection of the reproductive system and fever. The treatment is mainly anti-infection and symptomatic treatment with antibiotics. Since most women in the puerperium are in a relatively confined space, they are prone to respiratory tract infections, so they need to open windows regularly for ventilation. In case of fever due to acute mastitis, the symptoms can be relieved only if the milk is emptied in time.
