The bottom line No known interaction

We found no known interaction between Cocillana and Bupropion 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.

Cocillana and Bupropion

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 Bupropion and Cocillana 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 Cocillana at all — not against Bupropion, 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 Bupropion’s Own FDA Label Lists

This is not an interaction — none of it involves Cocillana. These are the most notable effects listed in the ADVERSE REACTIONS section of Bupropion’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.

  • Mania or an unusually elevated mood Worth acting on
  • Thoughts of self-harm Worth acting on
  • Trouble swallowing Worth acting on
  • Hallucinations Worth acting on
  • An irregular heartbeat Worth acting on
  • Confusion Worth acting on
  • Seizures Worth acting on
  • Chest pain Worth acting on
  • Raised blood pressure Worth acting on
  • Hives Worth acting on

Showing the 10 most notable of 43 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Bupropion. Read the label on DailyMed › Where a percentage is shown, it is the share of 152,137 voluntary FDA FAERS reports for Bupropion that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Cocillana’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Cocillana side to compare — that is a limit of the record, not a statement that Cocillana has no side effects.

Everything else you take

See Every Supplement That Interacts With Bupropion

This page covers Cocillana only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Bupropion page lists 46 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), African Wild Potato (moderate), Artichoke (moderate) and Astaxanthin (moderate).

By severity: 1 major · 33 moderate · 12 minor.

From our pharmacist’s overview on the Bupropion page

“Bupropion (Wellbutrin, Zyban) deserves genuine care around supplements, and the entry to understand first is activated charcoal, the only major-rated interaction on this list. Charcoal and similar bulk products can soak up the drug in the gut and blunt its effect, so space them well apart from your dose.”

About Cocillana

What is Cocillana?

  • Cough relief
  • Chest congestion
  • Loosening mucus (expectorant)
  • Bronchitis symptoms

Cocillana is a tree bark traditionally used as an expectorant in cough and cold remedies, often blended with other ingredients. There is very little modern scientific evidence to confirm how well it works, and it can cause nausea or vomiting in higher amounts, so use it cautiously and check with a pharmacist first.

Guarea rusbyi · Meliaceae · Dried bark · Liquid extract, tincture, syrup (often combined with other cough ingredients), tablets

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

Cocillana: dosing

There is no well-established standardized dose for cocillana, and it is usually found as one ingredient among several in cough products. Because higher doses can cause vomiting, the amounts used are typically small.If you choose to use a product containing cocillana, follow the directions on the label exactly and do not take more than recommended.
