DMSO: What It Is, When People Use It, and Safety Tips

Heard about DMSO and wondered if it’s useful or risky? DMSO (dimethyl sulfoxide) is a simple solvent with some surprising medical and lab uses. This page gives straight answers: what DMSO does, where it's actually approved, common off-label uses, and simple safety rules so you don't make a risky mistake.

What DMSO is and common uses

DMSO is a clear liquid that penetrates skin easily and carries other compounds with it. Medically, the FDA has approved a 50% DMSO solution (Rimso-50) for bladder instillation to treat pain from interstitial cystitis. In labs and clinics, people also use DMSO as a cryoprotectant—about 10% DMSO is standard for freezing cells and tissues. Veterinary medicine commonly uses topical DMSO for inflammation and pain in horses and dogs.

People also try topical DMSO for muscle and joint pain, nerve pain, and skin conditions. Evidence varies: the strongest, regulated use remains bladder instillation. For other uses you’ll find small studies, case reports, and a lot of anecdotal experience rather than big, clear clinical trials.

Safety, handling, and practical buying tips

DMSO’s greatest risk is how well it carries things through skin. That means any contaminant, medicine, or solvent on your skin can hitch a ride. Always wash the area first, and never mix DMSO with other topical drugs unless a clinician says it’s okay.

Common side effects you might notice: skin irritation, a sulfur or garlic-like taste or breath after use, and temporary redness. With very high or inappropriate use there are bigger risks—eye lens changes seen in some animal studies, and nerve or blood issues at extreme exposures. Because of that, avoid DMSO if you’re pregnant or breastfeeding unless directed by a specialist.

Buy medical-grade DMSO from reputable suppliers or compounding pharmacies. Don’t use industrial-grade DMSO from hardware stores—impurities can be dangerous. If you need DMSO for lab work, stick to cell-culture suppliers and follow the listed concentration and storage rules (many labs keep it cold and protect from light).

Always use gloves and eye protection when handling concentrated DMSO. Work in a ventilated area to avoid inhaling vapors. If you’re applying DMSO to skin, use clean, dry skin and a fresh applicator; wash hands afterward. If you experience severe irritation, breathing problems, or vision changes after exposure, seek medical help right away.
