In brief: DMSO has some clearly defined roles in research and medicine. These do not establish a broad spectrum of effects against cancer, autoimmune diseases, infections or neurological conditions.
Three levels that must not be confused
- Laboratory: DMSO serves as a solvent and is used to store frozen cells.
- Research: cell, animal and clinical studies investigate individual mechanisms or applications.
- Approved treatment: a specific preparation is assessed for a specific indication, dosage form and region.
Examples of medical use
One well-known example is a DMSO solution approved in the USA for use in the bladder in interstitial cystitis. DMSO may also be part of certain approved products or manufacturing processes. Status and use differ between countries.
Such an approval does not apply to arbitrary DMSO concentrations, other administration routes or automatically to other complaints. Use in a laboratory or as an excipient is not a therapeutic recommendation either.
What does research say about other applications?
Studies investigate inflammatory processes, tissue protection, drug delivery and pain, among other topics. Much of the literature is preclinical, older or uses very different preparations and study designs. Individual positive findings are not enough for a general promise of benefit.
For multiple sclerosis, lupus, cancer, colitis, herpes, leprosy and other serious conditions, DMSO must not be presented as a proven standard treatment. People with these diagnoses need evidence-based specialist care.
How can evidence be assessed?
Informative studies need an appropriate comparator group, enough participants, predefined endpoints and systematic recording of adverse effects. In addition, the studied product must match the subsequently advertised product in concentration, purity and use.
References to large numbers of published articles are not enough on their own. Basic chemistry papers, case reports and cell experiments must not be counted as equivalent clinical evidence of efficacy.
Risks and medical responsibility
Skin irritation, odour, nausea, headache and possible interactions must be considered. Because DMSO can affect the skin barrier, contaminants and substances applied at the same time are particularly relevant.
Criticism of authorities or lack of patentability proves neither efficacy nor suppression by the pharmaceutical industry. Reproducible data, product quality and a favourable benefit-risk balance are what matter.
Conclusion
DMSO is medically interesting, but not a versatile therapeutic agent for self-treatment. Every use must be assessed specifically by preparation, indication, authorisation and evidence.
