Superoxide dismutase is taken by mouth for removing wrinkles, rebuilding tissue, and extending the length of life. However, there is no evidence that superoxide dismutase products that are taken by mouth are absorbed by the body.
As a shot, superoxide dismutase is used for treating pain and swelling (inflammation) caused by osteoarthritis, sports injuries, and rheumatoid arthritis; a kidney condition called interstitial cystitis; gout; poisoning caused by a weed-killer called paraquat; cancer; and lung problems in newborns.
Superoxide dismutase is also given as a shot for improving tolerance to radiation therapy, improving rejection rates in kidney transplantation, and minimizing heart damage caused by heart attacks.
A sterile solution containing superoxide dismutase is sometimes applied directly to the eyes for treating ulcers on the cornea.
