Drug & supplement interaction

Dimethylsulfoxide (dmso) + Semaglutide

Semaglutide brand names: Ozempic, Rybelsus, Wegovy.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Dimethylsulfoxide (dmso) and Semaglutide in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Dimethylsulfoxide (dmso) and Semaglutide

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Semaglutide and Dimethylsulfoxide (dmso) in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Dimethylsulfoxide (dmso) safety at a glance

Dimethylsulfoxide... overall Use caution Topical use can irritate skin and may carry impurities; only pharmaceutical-grade products should ever be used.
Pregnancy Avoid Safety has not been established, so it is best to avoid during pregnancy.
Breastfeeding Avoid There is not enough safety information, so avoid while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Semaglutide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Semaglutide is filed under 2 classifications — antidiabetes drugs, oral drugs. Dimethylsulfoxide (dmso) has documented interactions with 8 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), carboplatin (paraplatin) (moderate) and cholinergic drugs (moderate) — and none of Semaglutide’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Dimethylsulfoxide (dmso) and Semaglutide May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • Raised blood pressure Worth acting on Additional detail

From our pharmacist’s overview on the Semaglutide page

“Semaglutide (Ozempic, Rybelsus, Wegovy) lowers blood sugar, and so do most of the 256 supplements on this page, which is why I read this list with real vigilance rather than a shrug. Nearly all of the entries either add to its glucose-lowering effect and raise the risk of hypoglycemia, or push sugar the other way and blunt it, as niaci…”

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.

Industrially produced chemical compound (a byproduct of wood pulp processing) · Topical cream, gel, liquid solution; bladder instillation solution (prescription); industrial-grade and pharmaceutical-grade liquids

An interaction check asks whether these two react with each other — it does not ask whether Dimethylsulfoxide (dmso) is a good idea for someone in your situation. Here is what our Dimethylsulfoxide (dmso) record says about it on its own.

Dimethylsulfoxide (dmso): dosing

There is no single standardized over-the-counter dose of DMSO for pain or arthritis.

About Semaglutide

What Is Semaglutide Used For?

Brand names: Ozempic, Rybelsus, Wegovy

Semaglutide is available as Wegovy (injection and tablet) and Ozempic (injection), and each product has its own approved uses. Wegovy injection is approved — alongside diet and exercise — to reduce excess body weight in adults and in children aged 12 and older with obesity, to lower the risk of serious heart events (heart attack, stroke, or cardiovascular death) in adults with obesity or overweight who also have established heart disease, and for treatment of a liver condition called MASH (metabolic dysfunction-associated steatohepatitis, formerly called NASH) with moderate-to-advanced scarring in adults. Wegovy tablets share the cardiovascular risk reduction and weight management uses in adults, but are not approved for MASH or for use in children. Ozempic injection is approved to improve blood sugar control in adults with type 2 diabetes (alongside diet and exercise) and to reduce the risk of major cardiovascular events in adults with type 2 diabetes who also have established heart disease.

All forms are used alongside a reduced-calorie diet and increased physical activity. Ozempic is not approved for type 1 diabetes. The MASH approval for Wegovy injection is an accelerated approval, meaning continued approval may depend on results from a confirmatory study.

Taking Dimethylsulfoxide (dmso) and Semaglutide Together: Common Questions

Is it safe to take Dimethylsulfoxide (dmso) with Semaglutide?
We do not list a known interaction between Dimethylsulfoxide (dmso) and Semaglutide. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Dimethylsulfoxide (dmso) and Semaglutide have any of the same side effects?
Yes — our sources link each of them separately to 10 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Dimethylsulfoxide (dmso) and Semaglutide combination checked?
Interactions in our licensed database are recorded against drug classes. Semaglutide is filed under 2 classifications, and Dimethylsulfoxide (dmso) has documented interactions with 8 drug classes — none of Semaglutide's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Dimethylsulfoxide (dmso) interact with any other medications?
Yes. Dimethylsulfoxide (dmso) has 339 documented drug interactions in our database — Semaglutide is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Semaglutide interact with any supplements?
Yes. Semaglutide has documented interactions with 256 supplements in our database — Dimethylsulfoxide (dmso) is not one of them. The Semaglutide interaction page linked on this page lists every one, ranked by severity.
