What is ENTONOX used for?

ENTONOX is a ready-to-use gas mixture consisting of 50% nitrous oxide and 50% oxygen; it is used exclusively for short term pain relief in a wide range of settings. It has the advantage of very rapid onset and offset analgesic action.

ENTONOX is widely used in obstetrics during childbirth, for emergency care in the ambulance service and for minor painful procedures in hospitals and clinics including:

  • acute trauma

  • suturing

  • wound dressings

  • colonoscopies
