Teazle 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 Teazle 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.

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.

From the ADVERSE REACTIONS section of the FDA label for Atazanavir, Cobicistat.

How to take them

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

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

What is Teazle?

Teazle
  • Lyme disease (folk use)
  • Joint and muscle pain
  • Osteoarthritis and rheumatoid arthritis
  • Skin conditions such as psoriasis
  • Wound healing

Teazle (Dipsacus fullonum) is a spiky plant used in traditional and folk medicine, most notably as a tincture marketed for Lyme disease and for joint pain and skin problems. There is very little high-quality human research to support any of these uses, so its benefits remain unproven. Talk with a pharmacist or doctor before trying it, and never use it to replace standard treatment for serious infections like Lyme disease.

Dipsacus fullonum · Caprifoliaceae · Root, leaves, and aerial parts · Tincture, tea, capsules, dried root, topical preparations

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

Teazle: dosing

There is no established or standardized dose for teazle. Dosing in folk traditions varies widely, and products such as tinctures and capsules differ in strength.If you choose to try a teazle product, follow the directions on the label and do not exceed them.

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.
