Spinach and Cabotegravir, Rilpivirine

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 Cabotegravir, Rilpivirine and Spinach 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.

How we checked

Why No Interaction Is Listed for Cabotegravir, Rilpivirine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cabotegravir, Rilpivirine is filed under 4 classifications — including non-nucleoside reverse transcriptase inhibitors (nnrtis), glucuronidated drugs, qt interval-prolonging drugs. Spinach has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and warfarin (coumadin) (moderate) — and none of Cabotegravir, Rilpivirine’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 Spinach Itself Has Been Linked To

This is not an interaction — nothing below involves Cabotegravir, Rilpivirine. It is the side-effect record for Spinach on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Spinach, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

Everything above comes from the Natural Medicines adverse-effect record for Spinach — expand a row for the licensed statement it rests on. We haven’t matched Cabotegravir, Rilpivirine to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Cabotegravir, Rilpivirine.

About Spinach

What is Spinach?

  • General nutrition and antioxidant support
  • Eye health
  • Heart health and blood pressure
  • Athletic performance
  • Constipation and digestive support

Spinach is a nutrient-dense leafy green that is a healthy part of a balanced diet, providing vitamins, minerals, fiber, and antioxidants. While it is very safe as a food, concentrated supplements and extracts are far less studied, and most specific health claims are not strongly proven. People prone to kidney stones or taking blood thinners should be mindful of its oxalate and vitamin K content.

Spinacia oleracea · Amaranthaceae · Leaves · Fresh or cooked leaves, powders, juice, capsules, and extracts

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

Spinach: dosing

There is no official standardized dose for spinach. As a food, it can be enjoyed in normal serving sizes as part of a balanced diet.For supplements such as powders, capsules, or extracts, a proven dose has not been established. More is not always better, especially given spinach's oxalate and vitamin K content.

About Cabotegravir and Rilpivirine Injections

What Is Cabotegravir and Rilpivirine Injections Used For?

Brand name: Cabenuva

CABENUVA (cabotegravir + rilpivirine) is used to treat HIV-1 infection in adults and adolescents 12 years and older who weigh at least 35 kg (about 77 lbs). It is not a starter treatment — it's designed for people who are already virologically suppressed, meaning their HIV is currently undetectable on a stable daily pill regimen and who have no history of treatment failure.

The goal is to keep the virus fully suppressed while freeing the person from taking a pill every day. Because it stays active in the body for weeks after each injection, strict adherence to the injection schedule is essential.
