Asparagus Racemosus and Alvimopan

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 Alvimopan 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 Alvimopan

Interactions in our licensed database are recorded against drug classes, not just single drug names. Alvimopan is filed under 2 classifications — p-glycoprotein substrates, oral drugs. Asparagus Racemosus has documented interactions with 2 drug classes — the most serious being diuretic drugs (moderate) and lithium (moderate) — and none of Alvimopan’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

What Alvimopan’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 Alvimopan’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. One of them is worth acting on rather than waiting out — marked below.

  • A heart attack Worth acting on mentioned in 9.3% of FDA reports for Alvimopan
  • Stomach upset

From the ADVERSE REACTIONS section of the FDA label for Alvimopan. Read the label on DailyMed › Where a percentage is shown, it is the share of 43 voluntary FDA FAERS reports for Alvimopan 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.

From our pharmacist’s overview on the Alvimopan page

“Alvimopan (Entereg) is given for a few days after bowel surgery to help the gut start moving again, and its supplement list warrants genuine care, with two entries rated major. St.”

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.

This medication is only given during a short hospital stay and is not for long-term or home use.

Most-Reported Side Effects for Alvimopan

From FAERS, the FDA’s public side-effect reporting system (43 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Hospitalisation 19 reports
Acute kidney injury 5 reports
