Drug & supplement interaction

Broccoli Sprout + Atazanavir, Cobicistat

Atazanavir, Cobicistat brand name: Evotaz.

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 Broccoli Sprout and Atazanavir, Cobicistat 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 label for Atazanavir, Cobicistat states a food rule worth keeping to, and 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.

Interaction report

Broccoli Sprout and Atazanavir, Cobicistat

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 Atazanavir, Cobicistat and Broccoli Sprout 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 Atazanavir, Cobicistat

Interactions in our licensed database are recorded against drug classes, not just single drug names. Atazanavir, Cobicistat is filed under 7 classifications — including protease inhibitors (pis), cytochrome p450 2c9 (cyp2c9) inhibitors, cytochrome p450 1a2 (cyp1a2) inhibitors. Broccoli Sprout has documented interactions with 2 drug classes — the most serious being cytochrome p450 1a2 (cyp1a2) substrates (minor) and cytochrome p450 2a6 (cyp2a6) substrates (minor) — and none of Atazanavir, Cobicistat’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

No Interaction Found — But Data Suggests Broccoli Sprout and Atazanavir, Cobicistat 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.

  • Stomach pain / Diarrhea Additional detail

    Broccoli Sprout

    “Orally, loose stools, diarrhea, abdominal pain, and abdominal cramping have been reported following intake of broccoli seed and broccoli sprout extracts, particularly at high doses. Consuming raw broccoli sprouts that have been improperly grown may cause food-borne illness. Improperly grown broccoli sprouts may be contaminated with bacteria, including Listeria monocytogenes, Salmonella, or Escherichia coli O157:H7.”

Special populations

Broccoli Sprout in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When COOKED broccoli sprouts are consumed in amounts commonly found in foods. Broccoli sprout is considered safe for dietary consumption provided the sprouts are grown in accordance with food safety recommendations developed by the US Food and Drug Administration (FDA) and are cooked prior to eating.

Pregnancy And Lactation Possibly Unsafe

When RAW broccoli sprouts are consumed in amounts commonly found in foods. There is evidence that uncooked broccoli sprouts may be contaminated with bacteria, including Listeria monocytogenes, Salmonella, or Escherichia coli O157:H7. Pregnant individuals are particularly susceptible to these food-borne illnesses, and becoming infected can increase the risk of miscarriage, stillbirth, premature birth, or neonatal infection. There is insufficient reliable information available about the safety of broccoli sprout extract during pregnancy or lactation; avoid using.

How to take them

Some Atazanavir, Cobicistat Products Have a Food Rule — Broccoli Sprout Should Not Break It

At least one FDA label for a product containing Atazanavir, Cobicistat says to take it with food. If you take Broccoli Sprout on an empty stomach out of habit, keep them separate — and take Atazanavir, Cobicistat with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Atazanavir, Cobicistat products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

(2.1) • Recommended dosage: One tablet once daily, taken orally with food in adults and pediatric patients weighing at least 35 kg.

From the Dosage and Administration section of the FDA label we read for Atazanavir, Cobicistat — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

About Broccoli Sprout

What is Broccoli Sprout?

  • Antioxidant support
  • Detoxification support
  • General heart health
  • Anti-inflammatory support
  • Digestive and gut health

Broccoli sprouts are young broccoli seedlings rich in a compound called sulforaphane, which is being studied for antioxidant, anti-inflammatory, and detoxification effects. Early research is promising for some uses, but high-quality human evidence is still limited, so they should be viewed as a healthy food rather than a proven treatment. As food they are generally safe, but talk to your pharmacist or doctor before using concentrated supplements, especially during pregnancy or breastfeeding.

Brassica oleracea var. italica · Brassicaceae · Young sprouts (seedlings) of the broccoli plant · Fresh sprouts, powders, capsules, tablets, and standardized extracts (often labeled as containing sulforaphane or glucoraphanin)

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

Broccoli Sprout: dosing

There is no official standardized dose for broccoli sprouts or their extracts. Studies have used different forms and amounts, often described by the amount of glucoraphanin or sulforaphane, which makes comparison difficult.If you are eating them as food, a serving as part of a balanced diet is reasonable. If you choose a supplement, follow the directions on the product label and choose a reputable brand.

About Atazanavir and Cobicistat

What Is Atazanavir and Cobicistat Used For?

Brand name: Evotaz

Evotaz (atazanavir/cobicistat) is used to treat HIV-1 infection. It must always be taken together with other antiretroviral medicines — it is not a complete regimen on its own. It is approved for adults and for pediatric patients who weigh at least 35 kg.

In patients who have been on HIV treatment before (treatment-experienced), how well Evotaz works depends on how much resistance to protease inhibitors the virus has already developed. Your prescriber will review this before starting you on Evotaz.
