Papain + Sarilumab
Sarilumab brand name: Kevzara.
We found no known interaction between Papain 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.
Papain 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 Papain 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.
Papain safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Sarilumab
Interactions in our licensed database are recorded against drug classes, not just single drug names. Sarilumab is filed under 2 classifications — cytochrome p450 3a4 (cyp3a4) inducers, immunosuppressants. Papain has documented interactions with 1 drug class — the most serious being warfarin (coumadin) (moderate) — and none of Sarilumab’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.
Papain Does Interact With Other Medications
Papain has 2 moderate known drug interactions in our database — Sarilumab isn’t one of them. If you take anything else, check it against the full list below.

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 Papain
What is Papain?
- Digestive support for protein digestion
- Wound cleaning (debridement of dead tissue)
- Sore throat and inflammation
- Sports injuries such as sprains
- Skin conditions
Papain is a protein-digesting enzyme from the papaya plant that is used in digestive supplements and some topical products. While it has clear food and laboratory uses, strong human evidence for most health claims is limited, and it can cause allergic reactions or throat irritation. Check with a pharmacist or doctor before using it, especially if you have a latex or papaya allergy.
Carica papaya · Caricaceae · Latex (sap) from the unripe fruit; also derived from leaves · Capsules, tablets, chewable digestive enzyme blends, topical ointments and gels, meat tenderizer powder
An interaction check asks whether these two react with each other — it does not ask whether Papain is a good idea for someone in your situation. Here is what our Papain record says about it on its own.
Papain: dosing
There is no official, standardized dose for papain. The amount in supplements varies widely between products and is often measured in enzyme activity units rather than milligrams.The safest approach is to follow the directions on the product label and not exceed the recommended amount.

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.
