DMSO is an inexpensive skin-penetrating solvent with real anti-inflammatory, pain-relieving, and antioxidant effects, plus an unusual ability to carry other substances into the body — its main promise and hazard. Strongest evidence backs easing a chronic bladder condition; fair support exists for short-term muscle and joint pain. Longevity claims rest only on laboratory worms. (Full Review)
| Marker | Target | Why |
|---|---|---|
| CBC (hemoglobin & hematocrit) | Hb ~13.5–15 g/dL (men), ~12.5–14 g/dL (women) | Screens for red-cell breakdown with systemic/intravesical exposure |
| Liver panel (ALT, AST) | ALT & AST ~10–26 U/L | Detects hepatic stress with prolonged high systemic exposure |
| Kidney function (creatinine, eGFR) | eGFR >90 mL/min/1.73m²; creatinine mid-normal | Confirms clearance capacity before higher-exposure use |
| Ophthalmologic lens exam (slit-lamp) | Clear lens, no new opacity or refractive shift | Watches for the animal-derived lens-change concern during sustained high-dose use |
Cadence: Reassess symptoms and skin at 1–2 weeks; repeat blood count and liver/kidney panels at ~3–6 months if high-exposure use continues; eye exam every 6–12 months for sustained high-dose systemic use.
