DMSO stands for dimethyl sulfoxide. The colourless sulphur compound is used as a solvent and in certain medical or pharmaceutical contexts. DMSO readily penetrates biological membranes and can carry other dissolved substances with it. This very property requires particular caution.
Possible side effects
The type and severity of a reaction depend on concentration, product quality, route of contact, duration and individual sensitivity. Reported effects include:
- redness, burning, itching, dryness or blistering of the skin
- a garlic-like or sulphurous smell and taste
- headaches, dizziness, nausea or gastrointestinal symptoms
- allergic or other hypersensitivity reactions
Redness, a feeling of warmth or an odour do not prove that DMSO “works” or that healing is beginning. Side effects must be assessed as risks, not as signs of success.
Transport through the skin
DMSO can increase skin permeability. Contaminants, cosmetics, residues on the skin or substances from unsuitable containers could therefore come into contact with the body more readily. Technical, industrial or veterinary products are not automatically suitable for human use.
Purity claims alone do not make unapproved self-use safe. Even with a high-quality product, concentration, administration route and the medical situation remain crucial.
Interactions with medicines
DMSO can influence the absorption and effects of other substances. Which interaction matters depends on the medicine, dose, administration route and individual. A medicine dose must therefore never be independently reduced, increased or omitted.
Even a “test with a small amount” does not prove safety: it cannot reliably exclude allergic reactions, systemic effects or interactions.
Approved uses are specific
Whether a DMSO-containing medicine is approved, and for what purpose, varies by country and specific product. Medical approval for one application cannot be transferred to freely sold solutions, other concentrations or other symptoms.
When medical help is needed
Severe pain, pronounced skin reactions, breathlessness, swelling, circulatory problems, confusion or other severe symptoms require immediate medical help. Eye or mucous membrane contact should be managed according to the product’s safety instructions and professionally assessed.
Important safety boundaries
- No self-treatment of diseases and no dosage experiments.
- Do not mix with medicines or other active substances.
- Do not change prescribed medicines.
- Do not use if the product’s origin, purity or purpose is unclear.
- Medical use only according to the product- and country-specific prescribing information and professional guidance.
