  • Dimethyl sulfoxide (C2H6OS), or DMSO, is a sulfur-containing organic compound. DMSO occurs naturally in vegetables, fruits, grains, and animal products. DMSO was first synthesized in 1866 as a byproduct of paper manufacturing. Therapeutic interest began in 1963. DMSO was reported to penetrate through the skin and produce analgesia, decrease pain, and promote tissue healing. DMSO is available for both non-medicinal and medicinal uses. The major clinical use of DMSO is to relieve symptoms of interstitial cystitis.
  • Potential toxic effects to the lens of the eye have been reported in animals but no effects have been noted in humans. Topical application has been associated with redness and inflammation of skin, and a garlic-like taste and odor on the breath have been reported.
  • DMSO has been used to treat amyloidosis, diabetic ulcers, extravasation, erosive gastritis, and ischemia prevention in surgical flaps, but well designed clinical trials are lacking. Because of the limited scientific evidence, whether DMSO provides effective treatment of patients with closed head trauma, herpes zoster, tendopathies, and complex regional pain syndrome will require more research.

Evidence Table


    These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

    Interstitial cystitis (chronic bladder infection)

    Intravesical DMSO is U.S. Food and Drug Administration (FDA)-approved for interstitial cystitis when given by a qualified healthcare professional. DMSO may work when other treatments have failed.


    DMSO may change the course of amyloidosis if treatment is started early. However, there is not much scientific support for this claim.

    Anesthesia (for kidney and gallbladder stone removal)

    Extracorporeal shock wave lithotripsy (ESWL) is sometimes used to break down kidney or gallbladder stones so that they can be passed in the urine. Treatment with DMSO may help reduce the pain of ESWL. Also, the diuretic, anti-inflammatory, muscle relaxant, and hydroxyl radical scavenger effects may also be beneficial for patients undergoing ESWL. However, more research is needed in this area.

    Diabetic ulcers

    Currently, there is not enough scientific evidence available to recommend for or against the use of topical DMSO for diabetic ulcers.

    Extravasation (drug accidentally going outside of a vein)

    DMSO applied to the skin may prevent tissue death after extravasation of anticancer agents. It can be applied alone or with steroids. Further research is needed to confirm these results.


    When used with acid-blocking drugs (like ranitidine), DMSO may help treat gastritis. More research is needed before this treatment can be recommended.

    Herpes zoster (shingles)

    DMSO may help treat herpes zoster. This treatment may work even better when used with the drug idoxuridine. Further research is necessary before a recommendation can be made.

    Inflammatory bladder disease

    DMSO may relieve the symptoms of inflammatory bladder disease. Further research is needed to confirm these results.

    Intracranial pressure

    DMSO may help treat high pressure in the skull (increased intracranial pressure), but most research is vague and results are conflicting. The risks may be greater than potential benefits.

    Pressure ulcers (prevention)

    Based on early research, massage therapy with a DMSO cream does not appear to effectively prevent pressure ulcers (also called bedsores). More research with DMSO alone is needed.

    Reflex sympathetic dystrophy

    Little research has been done to see if DMSO helps reflex sympathetic dystrophy. More studies in this area are needed before a decision can be made.

    Rheumatoid arthritis

    Applying DMSO to the skin may help rheumatoid arthritis. More study is needed before a conclusion can be drawn.

    Surgical skin flap ischemia

    One trial suggests that DSMO improves lack of blood flow (ischemia) in surgical flaps. More research is needed to confirm these results.


    A randomized, controlled, double-blind trial evaluating DMSO for acute tendopathies found a positive effect. Conclusions cannot be made without further trials.


    DMSO does not seem to help treat scleroderma and is therefore not recommended.

*Key to grades:



    The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.



    The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.

  • Adults (18 years and older)

    • Administering DMSO in the bladder (intravesically) is U.S. Food and Drug Administration (FDA)-approved for interstitial cystitis when given by a qualified healthcare professional.
    • There is no proven effective dose for DMSO for other conditions. DMSO has been taken by mouth in doses between 7 and 15 grams per day. Various solutions ranging from 10-100% DMSO have been applied on the skin. DMSO creams and gels have also been used.
  • Children (younger than 18 years)

    • There is not enough scientific information available to recommend the safe use of DMSO in children.



    The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

  • Allergies

    • Individuals with a known allergy or hypersensitivity to DMSO should avoid its use.
  • Side Effects and Warnings

    • Skin reactions are the most common side effects with topical (applied to the skin) administration and are usually reversible after discontinuing the drug. Erythema (reddening of the skin), pruritus (itching), burning, drying, scaling, blistering, dermatitis, and wheals have been reported. Cases of headache, dizziness, sedation, and agitation have also been reported. Encephalopathy, stroke, and heart attack have been reported after DMSO was used in stem cell transplantations.
    • Cautious use is advised in patients with urinary tract malignancies and with hepatic (liver) and renal (kidney) dysfunction. One clinical trial reported increased urgency, dysuria (difficult or painful urination), hematuria (blood in the urine), and red urine discoloration.
    • Cases of nausea, vomiting, constipation, halitosis (bad breath), garlic taste, and diarrhea have been reported. Other adverse effects that have been reported include anorexia, influenza-like symptoms, facial flushing from intravenous administration, and low blood pressure resulting from topical use. Negative effects on blood cell counts like eosinophilia and hemolysis have been reported to result from intravenous (into the vein) administration. Based on one case report, seizure occurred following a dimethylsulfoxide-preserved stem cell infusion.
  • Pregnancy and Breastfeeding

    • Not recommended due to lack of sufficient available data.



    Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.

  • Interactions with Drugs

    • Using DMSO with sulindac (Clinoril®) may cause peripheral neuropathy. Animal studies have reported that the action of sulindac may be decreased by DMSO. Although human data is lacking, this drug combination should be avoided.
  • Interactions with Herbs and Supplements

    • Insufficient available information.
