Acute mastitis usually does not require intravenous fluids unless there is an accompanying fever, a significant increase in white blood cells, and obvious local redness, swelling, and pain in the breast. At this time, intravenous antibiotic therapy can be considered, generally for five to seven days, but once the white blood cells normalize and the local acute swelling subsides, consideration can be given to stopping the treatment. Of course, when acute mastitis is complicated by an abscess, the abscess requires separate treatment, usually by a specialist making a small incision or using a thick syringe needle to repeatedly aspirate the pus; the best method is certainly to aspirate the pus through a small incision. In such cases, the duration of intravenous fluid use may be appropriately increased.
