DMSO is a prescription medicine and dietary supplement. It can be taken by mouth, applied to the skin (used topically), or injected into the veins (used intravenously or by IV).

DMSO is taken by mouth, used topically, or given intravenously for the management of amyloidosis and related symptoms. Amyloidosis is a condition in which certain proteins are deposited abnormally in organs and tissues.

DMSO is used topically to decrease pain and speed the healing of wounds, burns, and muscle and skeletal injuries. DMSO is also used topically to treat painful conditions such as headache, inflammation, rheumatoid arthritis , and severe facial pain called tic douloureux. It is used topically for eye conditions including cataracts, glaucoma, and problems with the retina; for foot conditions including bunions, calluses, and fungus on toenails; and for skin conditions including keloid scars and scleroderma. It is sometimes used topically to treat skin and tissue damage caused by chemotherapy when it leaks from the IV that is used to deliver it. DMSO is used either alone or in combination with a drug called idoxuridine to treat pain associated with shingles(herpes zoster infection).

Intravenously, DMSO is used to lower abnormally high blood pressure in the brain. It is also given intravenously to treat bladder infections (intestinal cystitis ) and chronic inflammatory bladder disease. The U.S. Food and Drug Administration (FDA) has approved certain DMSO products for placement inside the bladder to treat symptoms of chronic inflammatory bladder disease. DMSO is sometimes placed inside bile ducts with other medications to treat bile duct stones.

In manufacturing, DMSO is used as an industrial solvent for herbicides, fungicides, antibiotics, and plant hormones.

Used to address the following:

• A condition called amyloidosis. Some early research suggests that applying DMSO to the skin, taking DMSO by mouth, or washing the bladder with DMSO might help treat amyloidosis.
• Bile duct stones. Early research suggests that DMSO might help dissolve bile duct stones when infused into the bile duct with certain other solutions.
• Cancer-related pain. Early research suggests that injecting DMSO intravenously (by IV) along with sodium bicarbonate might improve quality of life in people with cancer-related pain.
• Foot ulcers associated with diabetes. Early research suggests that applying DMSO to the affected skin might improve the healing of foot ulcers in people with diabetes.
• High blood pressure in the brain. Some evidence suggests that DMSO might lower high blood pressure inside the brain when injected intravenously (by IV).
• Arthritis. Early research suggests that applying DMSO to the skin might help decrease symptoms of osteoarthritis or rheumatoid (RA).
• Stomach ulcers. Early research suggests that taking DMSO might be more effective than the drug cimetidine for treating ulcers in people with ulcers caused by bacteria called Helicobacter pylori or those with ulcers that haven't healed with other medications.
• Pressure ulcers. Early research suggests that applying DMSO 5% cream to the skin along with massage does not help prevent pressure ulcers in people living in nursing homes.
• Helping skin heal after surgery. Early research suggests that applying DMSO to the skin might help the skin heal after surgery.
• Tendon injuries (tendinopathy). Early research suggests that applying DMSO 10% gel to the skin might improve pain and joint movement in people with tendon injuries.
• Headaches.
• Eye problems.
• Gall stones.
• Muscle problems.
• Asthma.
• Skin problems such as calluses.
• Other conditions.
