Asparagus Racemosus and Pembrolizumab

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 Pembrolizumab and Asparagus Racemosus 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.

Asparagus Racemosus safety at a glance

Asparagus Racemosu... overall Use caution Generally considered well tolerated in traditional use, but high-quality safety data are limited.
Pregnancy Avoid Safety during pregnancy is not well established, so it is best avoided unless a doctor advises otherwise.
Breastfeeding Use caution It is traditionally used to support milk supply, but reliable safety data are lacking, so use only under professional guidance.

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

How we checked

Why No Interaction Is Listed for Pembrolizumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Pembrolizumab is filed under a single classification — antineoplastics. Asparagus Racemosus has documented interactions with 2 drug classes — the most serious being diuretic drugs (moderate) and lithium (moderate) — and none of Pembrolizumab’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 Pembrolizumab’s Own FDA Label Lists

This is not an interaction — none of it involves Asparagus Racemosus. These are the most notable effects listed in the ADVERSE REACTIONS section of Pembrolizumab’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Low magnesium Worth acting on
  • A change in thyroid levels Worth acting on
  • Trouble swallowing Worth acting on
  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Low potassium Worth acting on
  • A heart attack Worth acting on
  • Blood clots Worth acting on
  • Heart failure Worth acting on
  • High blood sugar Worth acting on

Showing the 10 most notable of 57 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Pembrolizumab. Read the label on DailyMed › Where a percentage is shown, it is the share of 100,432 voluntary FDA FAERS reports for Pembrolizumab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Asparagus Racemosus’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Asparagus Racemosus side to compare — that is a limit of the record, not a statement that Asparagus Racemosus has no side effects.

Overlapping uses

What Pembrolizumab Is Prescribed For, and What Asparagus Racemosus Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Pembrolizumab is a prescription medicine with approved uses on its FDA label. Asparagus Racemosus is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Pembrolizumab is prescribed for: Pembrolizumab is used to treat a wide range of cancers — including melanoma (skin cancer), lung cancer, head and neck cancers, bladder cancer, certain colorectal cancers, cervical cancer, kidney cancer, liver cancer, and many others. It can be used alone or combined with chemotherapy, depending on the cancer type and stage. For some cancers, it's given before surgery (neoadjuvant), after surgery (adjuvant), or both — to help shrink tumors or reduce the chance the cancer comes back. Some uses require a lab test to confirm your tumor has certain markers (like PD-L1 expression) before starting treatment.

Asparagus Racemosus has been studied for:

  • Cancer studied, not established Asparagus Racemosus has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Asparagus Racemosus for cancer

    Although there is interest in using oral Asparagus racemosus for cancer, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Pembrolizumab on your own; if you are taking Asparagus Racemosus for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Pembrolizumab

This page covers Asparagus Racemosus only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Pembrolizumab page lists 1 supplement it has a documented interaction with, worst first, each one explained.

The most serious there right now: American Pawpaw (minor).

By severity: 1 minor.

From our pharmacist’s overview on the Pembrolizumab page

“For a drug used against so many different cancers, pembrolizumab (Keytruda) has a remarkably short supplement file. Just one ingredient appears on it, American pawpaw, and even that lone entry is rated minor and judged unlikely to cause real trouble.”

About Asparagus Racemosus

What is Asparagus Racemosus?

Asparagus Racemosus
  • Women's reproductive health
  • Promoting breast milk supply
  • Digestive complaints
  • General tonic and stress support
  • Menopausal symptoms

Asparagus racemosus, often called shatavari, is an Ayurvedic herb traditionally used to support women's health, digestion, and overall vitality. Human evidence for most of these uses is limited and preliminary, so benefits are not well proven. Talk with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have hormone-sensitive conditions.

Asparagus racemosus · Asparagaceae · Roots (tuberous roots) · Capsules, tablets, powder (churna), liquid extracts, syrups

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

Asparagus Racemosus: dosing

There is no official, standardized dose for Asparagus racemosus. Products vary widely in strength and form, from powders to capsules to liquid extracts.The best approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Asparagus Racemosus and Pembrolizumab Together: Common Questions

Is it safe to take Asparagus Racemosus with Pembrolizumab?

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together.

How was the Asparagus Racemosus and Pembrolizumab combination checked?

Pembrolizumab is filed under 1 classification, and Asparagus Racemosus has documented interactions with 2 drug classes — none of Pembrolizumab's classifications are among them.
