HelloPharmacist Bottom Line
Our Pharmacist Explains
What is this? The interaction data in the HelloPharmacist supplement database is licensed from Natural Medicines Pro by TRC Healthcare (Therapeutic Research). HelloPharmacist pharmacists often add our own analysis and context on top of that licensed data — such as this Bottom Line summary and the notes on individual interaction pages — and any such commentary is noted as ours.

Efalizumab (Raptiva) works by quieting an overactive immune response in plaque psoriasis, and all 53 supplements on this list threaten it the same way, by stirring the immune system back up. Nothing rates major, 52 entries are moderate and one is minor, so for most people these combinations are manageable if you know what to watch. The risk is not added toxicity but lost ground: an immune-boosting herb like echinacea, astragalus, or ginseng could blunt the drug and let psoriasis flare.

Most of these pairings rest on lab or animal evidence rather than documented problems in people, which is why nothing climbed past moderate. Even so, the logic runs the same in every case. Anything marketed as immune support pulls against a drug you take precisely to hold immune activity down. If your psoriasis has been controlled and starts slipping, a supplement from this page is a reasonable first suspect.

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.
  • Each entry links to a full report with the clinical detail, likelihood, evidence level, and citations for that exact combination.
  • Content is reviewed by licensed HelloPharmacist pharmacists — see our data sources and editorial standards.

How Does Our Interaction Checker Work?

Behind every verdict on this page is a category system. Our source database doesn’t document supplement interactions drug-by-drug — it documents them against groups of medications that behave the same way (for example, “drugs processed by the CYP3A4 liver enzyme” or “blood-thinning medications”).

So the check works in three steps: (1) Efalizumab is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Efalizumab, and (3) each ingredient keeps its own severity, likelihood, and evidence grades from the underlying record. That’s why one supplement can carry several records for one drug — it may interact through more than one category.

Efalizumab sits in 1 interaction category. Open any one to see what the group means:

Immunosuppressants 53 ingredients

Medications that damp down the immune system. Supplements that stimulate immunity can work against them.

53 of the supplement ingredients on this page reach Efalizumab through this category.

Efalizumab & Supplements: Common Questions

What supplements interact with Efalizumab?
More than you might expect — 53 in total, though they are far from equal: 0 are rated major, 52 moderate, and 1 minor. The ranked list on this page puts the ones that genuinely matter first, and every entry opens a full report on that exact pair. The highest-ranked right now: Active Hexose Correlated Compound (ahcc), Alfalfa, American Ginseng.
Which Efalizumab supplement interactions are the most serious?
None of the Efalizumab supplement interactions on file are currently rated major. The most significant are the 52 moderate-rated ones — combinations that may need monitoring, a dose adjustment, or separated timing. Still worth a quick look through the ranked list for anything you take daily. Jump to the ranked list.
Can I take vitamins or supplements while on Efalizumab?
Usually yes — most people on Efalizumab can take most supplements. The catch is the exceptions, and they aren't always the exotic ones (St. John's Wort trips up more prescriptions than almost anything sold next to it). Look up each ingredient you actually take in the list above, and treat "no known interaction" as a green-ish light, not a guarantee. Try the label scanner or the interaction checker.
Do brands like Raptiva have the same supplement interactions as Efalizumab?
Yes — Raptiva all contain Efalizumab, so everything on this page applies to them equally. Interactions belong to the active drug, never to the brand on the box; the same is true of generics.
Where do these interaction ratings come from?
Every rating comes from the Natural Medicines database — the same evidence-graded reference pharmacists and hospitals use — and each interaction carries three separate grades: severity (how bad it can be), likelihood (how well it's documented in studies and case reports), and an evidence level. Our pharmacists review the content; we never let an AI decide an interaction. See how to read the ratings and our editorial policy.
What about Efalizumab and my other medications?
This page covers Efalizumab against supplements and herbal ingredients. Checking Efalizumab against your other prescription or OTC medications is a different tool — our drug interaction checker covers that side. Head to the drug–drug interaction checker.
