This medicine can be used in combination with other medicines to increase blood pressure in the management of severely low blood pressure due to sepsis (a bloodstream infection). Naloxone is administered intramuscularly (injected into the muscle), intravenously (through a vein in your arm), or subcutaneously (just below the skin).
