Dimethylsulfoxide (dmso) and Ibuprofen

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Dimethylsulfoxide (dmso) interacts with whole categories of medication. Ibuprofen falls into 2 of those categories, so it can interact with Dimethylsulfoxide (dmso) in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

1 of 2

Why this applies to Ibuprofen

Ibuprofen falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Dimethylsulfoxide (dmso) interacts with.

Theoretically, DMSO might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro evidence shows that DMSO inhibits adenosine diphosphate- and thrombin-induced platelet aggregation.
Severity Moderate Likelihood Possible Evidence D

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.

Here's the thing to know about pairing DMSO with ibuprofen. Ibuprofen already nudges your platelets toward not sticking together as easily, which is part of why it can cause stomach upset, bruising, or bleeding in some people. In lab dish studies, DMSO also seems to make platelets less likely to clump. So in theory, using both could add up and slightly raise your bleeding risk.

I want to be honest with you though: this is theoretical, based on test-tube findings, not on strong studies in real people. For most folks using occasional ibuprofen, it's unlikely to be a big deal. Still, if you notice easy bruising, nosebleeds, dark stools, or bleeding that won't stop, or if you're on blood thinners, please check in with your pharmacist or doctor first.

TOPICAL DRUGS

2 of 2

Ibuprofen also falls under TOPICAL DRUGS.

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 thing to know about DMSO: it's a powerful 'carrier' that can drive other substances through your skin and into your body. So if you're using a topical ibuprofen product (like a gel or cream) and apply DMSO over the same area, more of that ibuprofen may get absorbed than intended. In simple terms, your skin becomes more leaky to the drug.

Because ibuprofen is a working drug (not a prodrug), more absorption means a stronger effect and a higher chance of ibuprofen-type side effects, things like stomach upset, irritation at the site, or, with enough drug onboard, the usual NSAID concerns. This is based on animal work and limited human data, so it's a real but moderate concern. If you take ibuprofen as a pill, this skin interaction doesn't really apply. Either way, check with your pharmacist before combining them.

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

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.

About Ibuprofen

What Is Ibuprofen Used For?

Brand names: Motrin, Children's Motrin, Advil, Children's Advil, Fenbid Forte Gel, Ibugel Forte, Arthrofen, Ebufac, Rimafen, Calprofen, Fenpaed, Galprofen, Nurofen for Children, Orbifen for Children, Brufen, Brufen Retard, Fenbid, Tab-Profen, Ibuprofen, Calodor

Oral ibuprofen products (tablets, coated tablets, and liquid-filled capsules) are used to temporarily relieve minor aches and pains from headache, backache, toothache, muscular aches, menstrual cramps, minor arthritis pain, and the common cold, and to temporarily reduce fever. The oral prescription tablet (Ibu) is also indicated for the signs and symptoms of rheumatoid arthritis and osteoarthritis, mild to moderate pain, and primary dysmenorrhea (painful periods).

Caldolor, an intravenous (IV) form, is approved for adults and children 3 months and older to manage mild to moderate pain, to manage moderate to severe pain alongside opioid pain medicines, and to reduce fever. A separate intravenous solution, Ibuprofen Lysine, is used specifically in premature infants to close a patent ductus arteriosus (PDA) — an abnormal blood vessel connection near the heart — when standard medical management has not worked.
