The bottom line No known interaction

We found no known interaction between Cha De Bugre and Varenicline 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 Varenicline states a food rule worth keeping to.

Cha De Bugre and Varenicline

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 Varenicline and Cha De Bugre 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Cha De Bugre at all — not against Varenicline, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What Varenicline’s Own FDA Label Lists

This is not an interaction — none of it involves Cha De Bugre. These are the most notable effects listed in the ADVERSE REACTIONS section of Varenicline’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Kidney stones Worth acting on
  • Mania or an unusually elevated mood Worth acting on
  • Loss of vision Worth acting on
  • Dependence or withdrawal symptoms Worth acting on
  • Thoughts of self-harm Worth acting on
  • Hearing loss Worth acting on
  • A stroke or mini-stroke Worth acting on
  • A bowel blockage Worth acting on
  • Bone thinning Worth acting on
  • Memory problems Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Varenicline. Read the label on DailyMed › Cha De Bugre’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Cha De Bugre side to compare — that is a limit of the record, not a statement that Cha De Bugre has no side effects.

How to take them

Some Varenicline Products Have a Food Rule — Cha De Bugre Should Not Break It

At least one FDA label for a product containing Varenicline says to take it with food. If you take Cha De Bugre on an empty stomach out of habit, keep them separate — and take Varenicline 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 Varenicline 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.

Varenicline tablets should be taken orally after eating and with a full glass of water.

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

This page covers Cha De Bugre only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Varenicline page lists 20 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Beer (moderate), Coffee Charcoal (moderate), European Mandrake (moderate) and Glucomannan (moderate).

By severity: 1 major · 10 moderate · 9 minor.

From our pharmacist’s overview on the Varenicline page

“For anyone taking varenicline (Chantix, Champix, Tyrvaya) to quit smoking, this list earns real caution rather than a quick skim. Activated charcoal is the single entry rated major; it binds many medicines in the gut and can pull varenicline's blood levels down, and losing that support mid-quit is a genuine setback.”

About Cha De Bugre

What is Cha De Bugre?

  • Weight loss
  • Appetite control
  • Mild diuretic (water retention)
  • Cellulite
  • Energy and stimulation

Cha De Bugre is a Brazilian herbal tea traditionally used for weight loss and appetite control, but solid human research supporting these uses is lacking. Because it may have caffeine-like stimulant effects and its safety has not been well studied, talk with your pharmacist or doctor before trying it, and avoid it during pregnancy and breastfeeding.

Cordia salicifolia · Boraginaceae · Leaves · Tea, capsules, liquid extract
