Dimethylsulfoxide (dmso) and Diflorasone

Here is the interaction we found between these two, with the evidence behind it.

Moderate

TOPICAL DRUGS

Why this applies to Diflorasone

Diflorasone falls under TOPICAL DRUGS — the group Dimethylsulfoxide (dmso) interacts with.

Topical DMSO might increase the effects and adverse effects of topical drugs.
Evidence from animal studies and limited human studies suggests that DMSO may potentiate the action of numerous topical medications by increasing their absorption through the skin. This increase in absorption seems to depend on the concentration of DMSO and the molecular weight of the medication.
Severity Moderate Likelihood Possible Evidence B

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: Diflorasone is a strong topical steroid cream that you rub into the skin. DMSO is a solvent that's really good at carrying things through the skin. So if you put DMSO on the same area, it can push more of the diflorasone into your skin than your doctor intended. That means a stronger effect and a higher chance of side effects.

With a potent steroid like this, that could show up as thinning skin, stretch marks, easy bruising, acne-like bumps, or color changes where you applied it. Because diflorasone is already very strong, I'd keep these separate and check with your pharmacist or doctor before pairing them rather than combining them on your own.

From our pharmacist’s overview on the Diflorasone page

“DMSO is the ingredient to watch with diflorasone (Psorcon), a high-potency steroid cream for stubborn conditions like psoriasis. Applied to the same skin, DMSO may pull more of the steroid through than intended, amplifying both the benefit and side effects such as skin thinning.”

About Dimethylsulfoxide (dmso)

What is Dimethylsulfoxide (dmso)?

Dimethylsulfoxide (dmso)
  • Muscle and joint pain
  • Arthritis
  • Sprains and strains
  • Interstitial cystitis (bladder pain)
  • Skin penetration enhancer for other medicines

DMSO is a colorless liquid solvent that people apply to the skin for pain and inflammation, and it is FDA-approved (as a prescription) only for interstitial cystitis placed directly into the bladder. Most over-the-counter uses for pain and arthritis have limited or low-quality evidence, and DMSO can carry impurities or push other chemicals through your skin. Talk to your pharmacist or doctor before using it, and avoid industrial-grade products.
