Drug & supplement interaction

Serrapeptase + Rilonacept

Rilonacept brand name: Arcalyst.

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 Serrapeptase and Rilonacept 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.

Serrapeptase and Rilonacept

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 Rilonacept and Serrapeptase 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.

Serrapeptase safety at a glance

Serrapeptase overall Use caution Generally tolerated short-term, but long-term safety is not well studied.
Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.
Breastfeeding Avoid No reliable safety information, so avoid while breastfeeding.

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

No Interaction Found — But Data Suggests Serrapeptase and Rilonacept 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.

  • Stomach upset / Nausea Additional detail

    “Orally, some patients have reported experiencing epigastric pain, gastrointestinal upset, and nausea; however, these side effects appear to occur at the same rate as placebo.”

About Serrapeptase

What is Serrapeptase?

  • Inflammation and swelling
  • Sinus and respiratory congestion
  • Pain after surgery or injury
  • Joint and back pain
  • Thinning mucus

Serrapeptase is an enzyme marketed to reduce inflammation, swelling, pain, and mucus, but the human evidence is limited and mostly low quality. If you want to try it, choose an enteric-coated product, follow the label, and check with your pharmacist or doctor first—especially if you are pregnant, breastfeeding, or take other medicines.

Enzyme produced by bacteria (Serratia species) found in silkworms · Tablets, capsules (often enteric-coated)

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

Serrapeptase: dosing

There is no official or well-established dose for serrapeptase. Products are often measured in enzyme "units" rather than simple milligrams, and these vary between brands.The best approach is to follow the directions on the product label and not exceed them.

Do Serrapeptase and Rilonacept have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other.
