Hollyhock 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 Hollyhock 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 to take them

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

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

What is Hollyhock?

  • Sore throat and cough
  • Digestive upset
  • Soothing irritated skin
  • Mild inflammation
  • Urinary discomfort

Hollyhock is a flowering plant in the mallow family that has been used in traditional medicine, mainly as a soothing (demulcent) remedy for the throat, gut, and skin. Solid human studies are very limited, so its benefits are not well proven. It is generally considered gentle, but you should still talk to a pharmacist or doctor before using it, especially if you are pregnant or breastfeeding.

Alcea rosea · Malvaceae · Flowers, leaves, and roots · Tea, dried flowers, extracts, topical preparations

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

Hollyhock: dosing

There is no well-established, standardized dose for hollyhock. Traditional use most often involves a tea made from the dried flowers or leaves.Because products vary in strength and form, the safest approach is to follow the directions on the product label and not exceed the recommended amount.

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.
