Drug & supplement interaction

Ambrette + Atazanavir, Cobicistat

Atazanavir, Cobicistat brand name: Evotaz.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 20, 2026

The bottom line No known interaction

We found no known interaction between Ambrette 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

Ambrette 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 Ambrette 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.

Ambrette safety at a glance

Ambrette overall Use caution Limited human safety data exist, so use cautiously and mainly as a fragrance or flavoring.

Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.

Breastfeeding Possibly Unsafe When used orally or topically. Ambrette passes into mother's milk, but the effect is unknown. Read the full breastfeeding detail

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

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. Ambrette has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — 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 Ambrette and Atazanavir, Cobicistat May Share a Side Effect

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.

How to take them

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

At least one FDA label for a product containing Atazanavir, Cobicistat says to take it with food. If you take Ambrette 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.

Overlapping uses

What Atazanavir, Cobicistat Is Prescribed For, and What Ambrette Has Been Studied For

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

Atazanavir, Cobicistat is prescribed for: 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.

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

Ambrette for cancer

Although there has been interest in using oral ambrette for cancer, there is insufficient reliable information about the clinical effects of ambrette 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 Atazanavir, Cobicistat on your own; if you are taking Ambrette for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Atazanavir, Cobicistat page

“Evotaz (atazanavir with cobicistat) treats HIV, and its effectiveness depends on steady blood levels, so I read this list of 152 supplements and herbs carefully rather than casually. Only three carry a major rating, but those three deserve your attention first: St.”

About Ambrette

What is Ambrette?

Fragrance and aromatherapy
Digestive complaints
Respiratory complaints
Skin irritation
Insect repellent (traditional)

Ambrette (Abelmoschus moschatus) is a fragrant plant best known for its musky seed oil used in perfumes and food flavoring. It has a long history in traditional medicine for digestion, breathing problems, and skin issues, but solid human studies supporting these uses are lacking. If you want to try it, talk with your pharmacist or doctor first, and avoid use during pregnancy and breastfeeding.

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

Ambrette: dosing

There is no established standardized dose for ambrette as a supplement or medicine. Amounts used in foods and fragrances are small, and these uses have not been studied as treatments.If you choose to use an ambrette product, follow the directions on the label and do not exceed the recommended amount.

Taking Ambrette and Atazanavir, Cobicistat Together: Common Questions

Is it safe to take Ambrette with Atazanavir, Cobicistat?

We do not list a known interaction between Ambrette and Atazanavir, Cobicistat. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.

Do Ambrette and Atazanavir, Cobicistat have any of the same side effects?

Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.

Should I take Ambrette and Atazanavir, Cobicistat at the same time of day?

At least one FDA label for a product containing Atazanavir, Cobicistat says to take it with food. If you take Ambrette on an empty stomach out of habit, keep them separate and take Atazanavir, Cobicistat with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Atazanavir, Cobicistat products can differ — so check the directions on your own box. This is about absorption, not an interaction.

Are Ambrette and Atazanavir, Cobicistat used for the same thing?

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Ambrette in each. That is a conversation for your prescriber, especially if Atazanavir, Cobicistat is being adjusted to a target.

How was the Ambrette and Atazanavir, Cobicistat combination checked?

Interactions in our licensed database are recorded against drug classes. Atazanavir, Cobicistat is filed under 7 classifications, and Ambrette has documented interactions with 1 drug class — none of Atazanavir, Cobicistat's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.

Does Ambrette interact with any other medications?

Yes. Ambrette has 86 documented drug interactions in our database — Atazanavir, Cobicistat is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.

Does Atazanavir, Cobicistat interact with any supplements?

Yes. Atazanavir, Cobicistat has documented interactions with 152 supplements in our database — Ambrette is not one of them. The Atazanavir, Cobicistat interaction page linked on this page lists every one, ranked by severity.
