Drug & supplement interaction

Chlorine Dioxide + Sarilumab

Sarilumab brand name: Kevzara.

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 Chlorine Dioxide and Sarilumab 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.

Chlorine Dioxide and Sarilumab

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 Sarilumab and Chlorine Dioxide 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Chlorine Dioxide at all — not against Sarilumab, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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 Chlorine Dioxide and Sarilumab 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.

  • A skin rash reported in 13.3% of FDA reports for Sarilumab Additional detail

    Sarilumab

    Listed in the ADVERSE REACTIONS section of the FDA label for Sarilumab, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Chlorine Dioxide but not commonly for Sarilumab: confusion, an electrolyte imbalance, bloating or gas and kidney problems.

Effects for Sarilumab come from the ADVERSE REACTIONS section of its FDA label; effects for Chlorine Dioxide come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 24,738 voluntary FDA FAERS reports for Sarilumab 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.

Special populations

Chlorine Dioxide in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Unsafe

When used orally for medicinal purposes. Chlorine dioxide supplement products typically contain 28% sodium chlorite, which can provide 3-8 mg of chlorine dioxide per drop when mixed with citric acid as directed. Chlorine dioxide has been reported to cause serious complications, including severe vomiting and diarrhea, life-threatening low blood pressure, hemolysis, and acute liver failure. There is insufficient reliable information available about the safety of chlorine dioxide when used topically; avoid using.

See Every Supplement That Interacts With Sarilumab

This page covers Chlorine Dioxide only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Sarilumab page lists 72 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Active Hexose Correlated Compound (ahcc) (moderate), Alfalfa (moderate), Alkanna (moderate), Alpine Ragwort (moderate) and American Ginseng (moderate).

By severity: 71 moderate · 1 minor.

From our pharmacist’s overview on the Sarilumab page

“Sarilumab (Kevzara) works by quieting an overactive immune system in rheumatoid arthritis, and most of the supplements on this page push the other way. Immune stimulants such as ashwagandha, astragalus, and American ginseng could in theory blunt the drug's benefit and let joint symptoms creep back.”

About Chlorine Dioxide

What is Chlorine Dioxide?

Chlorine Dioxide
  • Falsely promoted as a cure for infections
  • Falsely promoted for COVID-19
  • Falsely promoted for cancer
  • Falsely promoted for autism
  • Water disinfection (industrial/regulated use only)

Chlorine dioxide products sold as 'Miracle Mineral Solution' (MMS) and similar names are essentially industrial bleach and are not safe to swallow. The FDA has issued strong warnings that drinking these products can cause serious, life-threatening harm, and there is no legitimate evidence they treat any disease. Do not consume chlorine dioxide supplements under any circumstances.

Not a plant; a chemical compound (chlorine dioxide gas, ClO2) · Liquid drops sold as 'Miracle Mineral Solution' (MMS), sodium chlorite solution mixed with an acid 'activator', water purification solution

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

Chlorine Dioxide: dosing

There is no safe or recommended dose of chlorine dioxide to take as a supplement. Health authorities, including the FDA, advise that these products should not be consumed at all.Any 'protocol' or dosing instructions found online or on product labels for MMS-type products should be ignored. If you have any of these products, do not use them. If you have already taken some, contact a healthcare provider or poison control right away.

About Sarilumab Injection

What Is Sarilumab Injection Used For?

Brand name: Kevzara

Kevzara (sarilumab) injection is approved for three conditions. In adults, it treats moderately to severely active rheumatoid arthritis (RA) when at least one other disease-modifying drug hasn't worked well enough or caused intolerance. It also treats polymyalgia rheumatica (PMR) in adults who haven't responded adequately to corticosteroids or who can't tolerate tapering them.

Kevzara is also approved for polyarticular juvenile idiopathic arthritis (pJIA) — a form of childhood arthritis — but only in patients who weigh 63 kg (about 139 lbs) or more. It is not approved for pediatric patients below that weight due to the lack of an appropriate dosage form.

Most-Reported Side Effects for Sarilumab

From FAERS, the FDA’s public side-effect reporting system (26,260 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Arthralgia 5,168 reports
Rheumatoid arthritis 4,646 reports
Joint swelling 4,578 reports
Fatigue 3,555 reports
Rash 3,349 reports

Taking Chlorine Dioxide and Sarilumab Together: Common Questions

Is it safe to take Chlorine Dioxide with Sarilumab?
We do not list a known interaction between Chlorine Dioxide and Sarilumab. 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 Chlorine Dioxide and Sarilumab 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.
Does Sarilumab interact with any supplements?
Yes. Sarilumab has documented interactions with 72 supplements in our database — Chlorine Dioxide is not one of them. The Sarilumab interaction page linked on this page lists every one, ranked by severity.
