Drug & supplement interaction

Lysine + Aldesleukin

Aldesleukin brand name: Proleukin.

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 Lysine and Aldesleukin 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.

Lysine and Aldesleukin

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 Aldesleukin and Lysine 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.

Lysine safety at a glance

Lysine overall Use caution Generally well tolerated at typical doses, but high amounts may cause stomach upset and long-term safety is not well studied.
Pregnancy Use caution Lysine from food is fine, but supplement safety in pregnancy is not well studied, so check with your doctor first.
Breastfeeding Use caution There is not enough reliable information on supplement use while breastfeeding, so caution is advised.

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

How we checked

Why No Interaction Is Listed for Aldesleukin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Aldesleukin is filed under 2 classifications — nephrotoxic drugs, hepatotoxic drugs. Lysine has documented interactions with 1 drug class — the most serious being 5-ht4 agonists (minor) — and none of Aldesleukin’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.

What to actually watch for

No Interaction Found — But Data Suggests Lysine and Aldesleukin 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. One of them is worth acting on rather than waiting out — marked below.

Everything else you take

See Every Supplement That Interacts With Aldesleukin

This page covers Lysine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Aldesleukin page lists 42 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Asarabacca (major), Beer (major), Siberian Cocklebur (major), Wine (major) and Aristolochia (moderate).

By severity: 4 major · 37 moderate · 1 minor.

From our pharmacist’s overview on the Aldesleukin page

“Aldesleukin (Proleukin) is high-dose immunotherapy for advanced kidney cancer and melanoma, and the drug is itself notoriously hard on the liver and kidneys, so this list earns real wariness. All 42 supplement interactions on file land on those same two organs: 38 ingredients can add liver strain and 6 can add kidney strain.”

About Lysine

What is Lysine?

  • Cold sores (herpes labialis)
  • Genital herpes outbreaks
  • Supporting protein and collagen formation
  • Calcium absorption support
  • General nutritional supplement

Lysine is an essential amino acid your body cannot make on its own, so it must come from food or supplements. People most often take extra lysine to try to prevent or shorten cold sores, but the evidence is mixed and far from conclusive. For most healthy people who eat enough protein, supplements are likely unnecessary, but they are generally considered low-risk at typical doses.

Amino acid (L-lysine) · Tablets, capsules, powder, topical creams (often combined with other ingredients)

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

Lysine: dosing

There is no single official supplement dose of lysine for any health condition, and a truly standardized dose has not been established for uses like cold sores. Products vary widely in how much they contain.The best approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Lysine and Aldesleukin Together: Common Questions

Is it safe to take Lysine with Aldesleukin?
We do not list a known interaction between Lysine and Aldesleukin. 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 Lysine and Aldesleukin 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. 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.
How was the Lysine and Aldesleukin combination checked?
Interactions in our licensed database are recorded against drug classes. Aldesleukin is filed under 2 classifications, and Lysine has documented interactions with 1 drug class — none of Aldesleukin's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Lysine interact with any other medications?
Yes. Lysine has 1 documented drug interaction in our database — Aldesleukin is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Aldesleukin interact with any supplements?
Yes. Aldesleukin has documented interactions with 42 supplements in our database — Lysine is not one of them. The Aldesleukin interaction page linked on this page lists every one, ranked by severity.
