U.S. - 50% [Rimso-50; GENERIC]; Canada - 50% [Rimso-50].
4.14 Exposure Standards and Regulations
The Approved Drug Products with Therapeutic Equivalence Evaluations List identifies currently marketed prescription drug products, incl dimethyl sulfoxide, approved on the basis of safety and effectiveness by FDA under sections 505 of the Federal Food, Drug, and Cosmetic Act.
Dimethyl sulfoxide solution. (a) Specifications. Dimethyl sulfoxide contains 90 percent of dimethyl sulfoxide and 10% of water ... (c) Conditions of use. (1) It is used or intended for use as a topical application to reduce acute swelling due to trauma ... (2) Not for use in horses and dogs intended for breeding purposes nor in horses slaughtered for food. Other topical medications should only be used when the dimethyl sulfoxide treated area is thoroughly dry. Do not administer by any other route (3) For use by or on the order of a licensed veterinarian.
Dimethyl sulfoxide get. (a) Specifications. Dimethyl sulfoxide gel, veterinary contains 90 percent dimethyl sulfoxide in an aqueous gel ... (c) Conditions of use-(1) Indications for use. For use on horses and dogs as a topical application to reduce acute swelling due to trauma. ... (3) Limitations. Do not use in horses and dogs intended for breeding purposes or in horses slaughtered for food. Restricted to topical use on horses and dogs only. Due to rapid penetrating ability of dimethyl sulfoxide, rubber gloves should be worn when applying the drug. No other medications should be present on the skin prior to application of the drug. Federal law restricts this drug to use by or on the order of a licensed veterinarian.
Fluocinolone acetonide, dimethyl sulfoxide solution. Fluocinolone acetonide, dimethyl sulfoxide solution. (a) Specifications. Each milliliter of solution contains 0.01 percent fluocinolone acetonide and 20 percent dimethyl sulfoxide with propylene glycol and citric acid. ... (c) Conditions of use. (1) The drug is used in dogs for the relief of impaction commonly present in apparently normal anal sacs, for the reversal of inflammatory changes associated with abnormal anal sacs, and to counteract the offensive odor of anal sac secretions. ... (3) For use only by or on the order of a licensed veterinarian.
Fluocinolone acetonide, dimethyl sulfoxide otic solution. (a) Specifications. Each milliliter of solution contains 0.01 percent of fluocinolone acetonide in 60 percent dimethyl sulfoxide with propylene glycol and citric acid. ... (c) Conditions of use. (1) The drug is used in dogs for the relief of pruritis and inflammation associated with acute and chronic otitis. ... (3) There should be careful initial evaluation and followup of infected ears. Incomplete response or exacerbation of corticosteroid-responsive lesions may be due to the presence of an infection which requires identification or antibiotic sensitivity testing, and the use of the appropriate antimicrobial agent. As with any corticosteroid, animals with a generalized infection should not be treated with this product without proper supportive antimicrobial therapy. Preparations with dimethyl sulfoxide should not be used in pregnant animals. For use by or on the order of a licensed veterinarian.
4.15 Reactivities and Incompatibilities
Can react with oxidizing materials.

Incompatible with magnesium perchlorate, metal oxosalts, perchloric acid, periodic acid, sulfur trioxide.
Forms powerfully explosive mixtures with metal salts of oxoacids (eg aluminum perchlorate, sodium perchlorate, and iron (III) nitrate).
4.16 Other Preventative Measures
... DMSO can be harmful. ... Use effective fume removal device.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
4.17 Protective Equipment and Clothing
... Based on chemical and physical properties alone, /dimethyl sulfoxide/ is ranked 10th/ of the ten most potentially irritating solvents /From table/.
4.18 Specification

? Dimethyl sulfoxide with a CAS number of 67-68-5. This colorless liquid is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water. It has a distinctive property of penetrating the skin very readily, so that one may taste it soon after it comes into contact with the skin. Its taste has been described as oyster- or garlic-like.
Chemical Stability of Dimethyl sulfoxide (CAS NO. 67-68-5): Stable under normal temperatures and pressures. Hygroscopic: absorbs moisture or water from the air.
Conditions to Avoid: Incompatible materials, exposure to moist air or water.
? Dimethyl sulfoxide is incompatibilities with Other Materials Strong oxidizing agents, perchloric acid.
Hazardous decomposition products of?Dimethyl sulfoxide are carbon monoxide, oxides of sulfur, carbon dioxide, formaldehyde.
Hazardous polymerization of Dimethyl sulfoxide will not occur.

4.19 Octanol/Water Partition Coefficient
log Kow = -1.35
4.20 Disposal Methods
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
