Xylocaine is used to prevent or relieve pain, but it will not put you to sleep.
Xylocaine is also used after surgery to relieve pain. It can also be used to make childbirth less painful.
Xylocaine belongs to a group of medicines called local anaesthetics. It is injected into the body where it makes the nerves unable to pass messages to the brain.
Depending on the amount used, Xylocaine will either totally stop pain or will cause a partial loss of feeling.
Xylocaine is sometimes combined with adrenaline (epinephrine) to make it last longer. Adrenaline (epinephrine) makes the blood vessels at the site of injection narrower, which keeps the Xylocaine where it is needed for a longer time.
Your doctor will have explained why you are being treated with Xylocaine and told you what dose you will be given.
