You may be given a course of oral antibiotics if you have a mild case of cellulitis. If it’s severe, you will be given intravenous (IV) antibiotics in the hospital.
Should the infection progress to sepsis, you will need to be treated aggressively. You will need antibiotics right away and IV fluids to prevent dehydration.
If your blood pressure drops, you will be given a vasopressor medication, which constricts your blood vessels to raise blood pressure.
You will also be given supportive care based on your symptoms. That could once again include oxygen or a breathing machine. If your kidneys are affected, it could include dialysis.
In some cases, surgery may be needed to remove dead tissues or amputate a limb. This is a last resort (and an extremely rare one at that), but it will ensure the entire infection is gone.
