Overview

Dimethyl sulfoxide is an anti inflammatory that is FDA approved for the treatment of symptomatic relief of patients with interstitial cystitis. Common adverse reactions include garlic breath, garlic taste, chemical cystitis.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

  • Dimethyl sulfoxide is indicated for the symptomatic relief of patients with interstitial cystitis. Dimethyl sulfoxide has not been approved as being safe and effective for any other indication.
  • There is no clinical evidence of effectiveness of dimethyl sulfoxide in the treatment of bacterial infections of the urinary tract.
  • Instillation of 50 mL of dimethyl sulfoxide directly into the bladder may be accomplished by catheter or aseptic syringe and allow to remain for 15 minutes. Application of an analgesic lubricant gel such as lidocaine jelly to the urethra is suggested prior to insertion of the catheter to avoid spasm. The medication is expelled by spontaneous voiding. It is recommended that the treatment be repeated every two weeks until maximum symptomatic relief is obtained. Thereafter, time intervals between therapy may be increased appropriately.
  • Administration of oral analgesic medication or suppositories containing belladonna and opium prior to the instillation of dimethyl sulfoxide can reduce bladder spasm.
  • In patients with severe interstitial cystitis with very sensitive bladders, the initial treatment, and possibly the second and third (depending on patient response) should be done under anesthesia. (Saddle block has been suggested).
  • Instillation of 50 mL of dimethyl sulfoxide directly into the bladder may be accomplished by catheter or asepto syringe and allow to remain for 15 minutes. Application of an analgesic lubricant gel such as lidocaine jelly to the urethra is suggested prior to insertion of the catheter to avoid spasm. The medication is expelled by spontaneous voiding. It is recommended that the treatment be repeated every two weeks until maximum symptomatic relief is obtained. Thereafter, time intervals between therapy may be increased appropriately.

Overdosage

  • The oral LD50 of dimethyl sulfoxide in the dog is greater than 10 gm/kg. It is improbable that this dosage level could be obtained with intravesical instillation of dimethyl sulfoxide in the patient.
  • In case of accidental oral ingestion, specific measures should be taken to induce emesis. Additional measures which may be considered are gastric lavage, activated charcoal and force diuresis.

Mechanism of Action

There is limited information regarding Dimethyl sulfoxide Mechanism of Action in the drug label.

Structure

RIMSO-50®(dimethyl sulfoxide) (DMSO) 50% w/w Aqueous Solution for intravesical instillation.

Each mL contains 0.54 gm dimethyl sulfoxide STERILE AND NON-PYROGENIC.

Intravesical instillation for the treatment of interstitial cystitis.

NOT FOR INTRAMUSCULAR OR INTRAVENOUS INJECTION.

  • The active component of the compound is dimethyl sulfoxide which has the empirical formula C2H6OS, and is structurally represented as:
This image is provided by the National Library of Medicine.
  • Dimethyl sulfoxide is a clear, colorless and essentially odorless liquid which is miscible with water and most organic solvents. Other physical characteristics include: molecular weight 78.13, melting point 18.3° C, and a specific gravity of 1.096.

Pharmacodynamics

There is limited information regarding Pharmacodynamics of Dimethyl sulfoxide in the drug label.

Pharmacokinetics

  • Dimethyl sulfoxide is metabolised in man by oxidation to dimethyl sulfone or by reduction to dimethyl sulfide. Dimethyl sulfoxide and dimethyl sulfone are excreted in the urine and feces.
  • Dimethyl sulfide is eliminated through the breath and skin and is responsible for the characteristic odor from patients on dimethyl sulfoxide medication. Dimethyl sulfone can persist in serum for longer than two weeks after a single intravesical instillation. No residual accumulation of dimethyl sulfoxide has occurred in man or lower animals who have received treatment for protracted periods of time. Following topical application, dimethyl sulfoxide is absorbed and generally distributed in the tissues and body fluids.

Nonclinical Toxicology

There is limited information regarding Nonclinical Toxicology of Dimethyl sulfoxide in the drug label.

Patient Counseling Information

  • Dimethyl sulfoxide is a sterile solution of 50% dimethyl sulfoxide (DMSO) and 50% water that has been approved by the U.S. Food and Drug Administration for use in the symptomatic relief of patients with interstitial cystitis.
  • Dimethyl sulfoxide will be instilled in the bladder on an inpatient or out-patient basis, which will be determined by your physician.
  • Some data indicate that dimethyl sulfoxide could change the effectiveness of medication(s) that you may be presently receiving. Be sure to mention the name and dosage of all medicines you are taking to your physician before a dimethyl sulfoxide instillation.
  • A garlic-like taste may be noted by the patient within a few minutes after instillation of dimethyl sulfoxide. This taste may last several hours. An odor on the breath and skin may be present and remain for up to 72 hours.
  • Some patients may experience discomfort on administration of the drug. Usually this becomes less prominent with repeated administration.
  • If you are pregnant or nursing, ask your physician about the advisability of using RIMSO-50®.
  • Some eye changes have been observed in animals treated with DMSO in large doses for prolonged periods. Therefore your doctor may want you to have eye evaluations, including slit lamp examinations prior to and periodically during treatment.

Precautions with Alcohol

  • Alcohol-Dimethyl sulfoxide interaction has not been established. Talk to your doctor about the effects of taking alcohol with this medication.
