Drug & supplement interaction

Dimethylsulfoxide (dmso) + Peramivir

Peramivir brand name: Rapivab.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Dimethylsulfoxide (dmso) and Peramivir 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 Peramivir

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 Peramivir 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.

No Interaction Found — But Data Suggests Dimethylsulfoxide (dmso) and Peramivir May Share a Side Effect

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.

  • Diarrhea Additional detail

    Peramivir

    Listed in the ADVERSE REACTIONS section of the FDA label for Peramivir. Read the label on DailyMed ›

Reported for Dimethylsulfoxide (dmso) but not commonly for Peramivir: an irregular heartbeat, a fast or pounding heartbeat, stomach pain and chest pain.

Effects for Peramivir come from the ADVERSE REACTIONS section of its FDA label; effects for Dimethylsulfoxide (dmso) come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 155 voluntary FDA FAERS reports for Peramivir that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Peramivir Is Prescribed For, and What Dimethylsulfoxide (dmso) Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Peramivir is a prescription medicine with approved uses on its FDA label. Dimethylsulfoxide (dmso) is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Peramivir is prescribed for: Rapivab (peramivir injection) is used to treat acute uncomplicated influenza — the flu — in adults and children as young as 6 months old. It must be started within 2 days of when symptoms first appear to be effective. Most of the clinical trial evidence comes from patients with influenza A. Fewer patients with influenza B were studied, so effectiveness against influenza B is less certain.

Read the rest of what Peramivir is prescribed for

Rapivab has not been shown to work for serious influenza requiring hospitalization, and it does not treat bacterial infections.

Dimethylsulfoxide (dmso) has been studied for:

  • Headache studied, not established Dimethylsulfoxide (dmso) has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Dimethylsulfoxide (dmso) for headache

    Although there has been interest in using topical DMSO for headache, there is insufficient reliable information about the clinical effects of DMSO for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Peramivir on your own; if you are taking Dimethylsulfoxide (dmso) for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

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.

Taking Dimethylsulfoxide (dmso) and Peramivir Together: Common Questions

Is it safe to take Dimethylsulfoxide (dmso) with Peramivir?
We do not list a known interaction between Dimethylsulfoxide (dmso) and Peramivir. 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 Peramivir have any of the same side effects?
Yes — our sources link each of them separately to one 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.
Are Dimethylsulfoxide (dmso) and Peramivir used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Dimethylsulfoxide (dmso) in each. That is a conversation for your prescriber, especially if Peramivir is being adjusted to a target.
Does Dimethylsulfoxide (dmso) interact with any other medications?
Yes. Dimethylsulfoxide (dmso) has 339 documented drug interactions in our database — Peramivir is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
