No Known Interaction
The bottom line No known interaction

We found no known interaction between Vetiver 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.

Vetiver 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 Vetiver 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 Vetiver 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.

What Sarilumab’s Own FDA Label Lists

This is not an interaction — none of it involves Vetiver. These are the most notable effects listed in the ADVERSE REACTIONS section of Sarilumab’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 6 of them are worth acting on rather than waiting out — marked below.

  • A low platelet count Worth acting on
  • A low white blood cell count Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • A higher chance of infection Worth acting on
  • An allergic reaction Worth acting on
  • Joint pain mentioned in 55.8% of FDA reports for Sarilumab
  • Tiredness mentioned in 13.8% of FDA reports for Sarilumab
  • Muscle pain
  • A skin rash mentioned in 13.3% of FDA reports for Sarilumab

Showing the 10 most notable of 12 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Sarilumab. Read the label on DailyMed › 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. Vetiver’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Vetiver side to compare — that is a limit of the record, not a statement that Vetiver has no side effects.

See Every Supplement That Interacts With Sarilumab

This page covers Vetiver 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 Vetiver

What is Vetiver?

  • Relaxation and stress relief (aromatherapy)
  • Sleep support
  • Skin care and soothing irritated skin
  • Insect repellent
  • Traditional cooling tonic

Vetiver is a fragrant grass whose roots produce an essential oil widely used in perfumes and aromatherapy for relaxation. Human evidence for any health benefit is very limited, so it is best thought of as a pleasant scent rather than a proven remedy. The oil should be diluted before skin use and is not meant to be swallowed.

Chrysopogon zizanioides · Poaceae · Roots and the essential oil distilled from them · Essential oil, aromatherapy blends, soaps and skin-care products, dried roots, perfume ingredient

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

Vetiver: dosing

There is no established or standardized medicinal dose for vetiver. It is most often used as an aromatherapy oil (a few drops in a diffuser) or applied to the skin after being diluted in a carrier oil such as coconut or jojoba.Follow the directions on the specific product you buy, since concentration and quality vary between brands.

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
