Drug & supplement interaction

Podophyllum + Idelalisib

Idelalisib brand name: Zydelig.

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 Podophyllum and Idelalisib 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.

Podophyllum and Idelalisib

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 Idelalisib and Podophyllum 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 Podophyllum at all — not against Idelalisib, 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 to actually watch for

No Interaction Found — But Data Suggests Podophyllum and Idelalisib 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.

Reported for Podophyllum but not commonly for Idelalisib: hallucinations, kidney problems, a change in taste and raised blood pressure.

Effects for Idelalisib come from the ADVERSE REACTIONS section of its FDA label; effects for Podophyllum come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 7,040 voluntary FDA FAERS reports for Idelalisib 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.

About Podophyllum

What is Podophyllum?

  • Genital and skin warts (topical)
  • Constipation (historical/traditional laxative)
  • Digestive complaints (homeopathic)
  • Watery diarrhea (homeopathic)
  • Liver and gallbladder remedies (traditional)

Podophyllum (American mayapple) is a toxic plant whose resin contains podophyllotoxin, used in prescription topical products to treat warts. The raw plant and crude resin are poisonous if taken by mouth and should never be self-used. Only use FDA-approved wart products exactly as directed and under medical guidance.

Podophyllum peltatum · Berberidaceae · Dried root and rhizome (and the resin extracted from it, called podophyllin) · Topical resin/solution (prescription podophyllin and podofilox), homeopathic preparations; historically a crude purgative

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

Podophyllum: dosing

There is no safe self-care oral dose for podophyllum, and the whole plant should not be taken by mouth. For warts, dosing is determined entirely by the strength of the prescription product and your clinician's instructions.If you are prescribed a topical podophyllin or podofilox product, use only the amount directed, apply it only to the warts, and follow the schedule and wash-off instructions exactly. Never increase the amount or frequency on your own.

Zydelig (idelalisib) is approved to treat relapsed chronic lymphocytic leukemia (CLL) — a cancer of the blood and bone marrow — when used together with rituximab.

It is also not approved in combination with bendamustine and rituximab, or with rituximab alone, for FL, SLL, or other slow-growing non-Hodgkin lymphomas.

Taking Podophyllum and Idelalisib Together: Common Questions

Is it safe to take Podophyllum with Idelalisib?
We do not list a known interaction between Podophyllum and Idelalisib. 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 Podophyllum and Idelalisib have any of the same side effects?
Yes — our sources link each of them separately to 5 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 Idelalisib interact with any supplements?
Yes. Idelalisib has documented interactions with 143 supplements in our database — Podophyllum is not one of them. The Idelalisib interaction page linked on this page lists every one, ranked by severity.
