No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Bog Labrador Tea and 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 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

Bog Labrador Tea and 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 Cobicistat and Bog Labrador Tea 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 Cobicistat

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cobicistat is filed under 2 classifications — cytochrome p450 3a4 (cyp3a4) inhibitors, oral drugs. Bog Labrador Tea has documented interactions with 1 drug class — the most serious being cytochrome p450 3a4 (cyp3a4) substrates (moderate) — and none of 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 Bog Labrador Tea and 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.

  • Diarrhea / Vomiting Additional detail

    “Orally, bog Labrador tea seems to be generally well tolerated when consumed in small amounts. However, frequent consumption of bog Labrador tea in large quantities can cause vomiting, gastroenteritis, diarrhea, diuresis, and central nervous system depression including symptoms of dizziness, drowsiness, and exhaustion.”

How to take them

Some Cobicistat Products Have a Food Rule — Bog Labrador Tea Should Not Break It

At least one FDA label for a product containing Cobicistat says to take it with food. If you take Bog Labrador Tea on an empty stomach out of habit, keep them separate — and take 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 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 DOSAGE AND ADMINISTRATION TYBOST must be coadministered with atazanavir or darunavir at the same time, with food, and in combination with other HIV-1 antiretroviral agents.

From the Dosage and Administration section of the FDA label we read for 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.

Everything else you take

See Every Supplement That Interacts With Cobicistat

This page covers Bog Labrador Tea only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cobicistat page lists 30 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), Cannabidiol (cbd) (moderate), Cannabinol (cbn) (moderate) and Cannabis (moderate).

By severity: 1 major · 19 moderate · 10 minor.

From our pharmacist’s overview on the Cobicistat page

“Activated charcoal is the one entry to understand first if you take cobicistat (Tybost). Charcoal soaks up drugs in the gut, and since cobicistat's entire job is boosting an HIV medicine to protective levels, blunting its absorption can put the whole regimen at risk.”

About Bog Labrador Tea

What is Bog Labrador Tea?

Bog Labrador Tea
  • Coughs and respiratory complaints
  • Digestive upset and diarrhea
  • Anxiety and stress
  • As a warm beverage
  • Aches and pains (traditional use)

Bog Labrador tea is a wetland shrub whose leaves have long been brewed as a traditional beverage and folk remedy, especially among Indigenous peoples of North America. There is very little human research to confirm any health benefit, and the plant is closely related to species that contain toxic compounds, so it should be used cautiously and in moderation. Pregnant or breastfeeding people should avoid it, and anyone considering it should talk with a pharmacist or doctor first.

Rhododendron groenlandicum · Ericaceae · Leaves (used for tea); essential oil from leaves · Dried leaf tea, infusions, tinctures, essential oil

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

Bog Labrador Tea: dosing

There is no established or standardized dose for Bog Labrador tea. Traditionally, a small amount of dried leaves is steeped in hot water to make a light beverage, and overly strong or long-steeped brews are avoided because of possible toxic compounds.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

About Cobicistat

What Is Cobicistat Used For?

Brand name: Tybost

Tybost (cobicistat) is not itself an HIV treatment — it works by slowing the breakdown of certain HIV medicines so they stay active in your body long enough to work. Specifically, Tybost is used to boost the HIV medicines atazanavir or darunavir (once-daily dosing) as part of a complete HIV-1 treatment regimen in adults and in children weighing at least 14 kg (about 31 lbs).

Tybost is not interchangeable with ritonavir (another booster) for all HIV medicines. It is not recommended with darunavir twice-daily, fosamprenavir, saquinavir, or tipranavir.

Most-Reported Side Effects for Cobicistat

From FAERS, the FDA’s public side-effect reporting system (20,779 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Bone density decreased 8,112 reports
Chronic kidney disease 4,754 reports

Taking Bog Labrador Tea and Cobicistat Together: Common Questions

Is it safe to take Bog Labrador Tea with Cobicistat?
We do not list a known interaction between Bog Labrador Tea and 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 Bog Labrador Tea and Cobicistat have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Bog Labrador Tea and Cobicistat at the same time of day?
At least one FDA label for a product containing Cobicistat says to take it with food. If you take Bog Labrador Tea on an empty stomach out of habit, keep them separate and take Cobicistat with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Cobicistat products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Bog Labrador Tea and Cobicistat combination checked?
Interactions in our licensed database are recorded against drug classes. Cobicistat is filed under 2 classifications, and Bog Labrador Tea has documented interactions with 1 drug class — none of 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 Bog Labrador Tea interact with any other medications?
Yes. Bog Labrador Tea has 643 documented drug interactions in our database — 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 Cobicistat interact with any supplements?
Yes. Cobicistat has documented interactions with 30 supplements in our database — Bog Labrador Tea is not one of them. The Cobicistat interaction page linked on this page lists every one, ranked by severity.
