For fever in acute mastitis, it is first recommended to obtain a complete blood test to check if white blood cells and neutrophils are elevated. Of course, there are basic conservative methods and medication treatments for fever reduction. The conservative approach includes drinking plenty of water, preferably warm. Secondly, local application of magnesium sulfate can be used, with concentrations ranging from 33%-50%. During hot weather, it can be applied directly as a wet compress on the inflamed breast. It is important to thoroughly clean the breast, especially the nipple, before breastfeeding to prevent the baby from ingesting magnesium sulfate, which can cause diarrhea in infants. Thirdly, if the blood test shows an increase in white blood cells and neutrophils, intravenous antibiotics are used, commonly referred to by people as anti-inflammatory injections. Using antibacterial medications at this time can rapidly reduce fever. The fourth method is to temporarily use fever-reducing medications, which, along with magnesium sulfate, are available at pharmacies. However, for antibiotics, it is best to go to a hospital.
