We found no known interaction between Cheken and Protriptyline 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.

Cheken and Protriptyline

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 Protriptyline and Cheken 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 Cheken at all — not against Protriptyline, 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 Protriptyline’s Own FDA Label Lists

This is not an interaction — none of it involves Cheken. These are the most notable effects listed in the ADVERSE REACTIONS section of Protriptyline’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
  • Dependence or withdrawal symptoms Worth acting on
  • A bowel blockage Worth acting on
  • Trouble passing urine Worth acting on
  • Unsteadiness Worth acting on
  • A heart attack Worth acting on
  • Hallucinations Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Confusion Worth acting on
  • Seizures Worth acting on

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

See Every Supplement That Interacts With Protriptyline

This page covers Cheken only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Protriptyline page lists 93 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Henbane (major), Lithium (major), Scopolia (major) and 5-htp (moderate).

By severity: 4 major · 71 moderate · 18 minor.

From our pharmacist’s overview on the Protriptyline page

“Protriptyline (Vivactil) is an older tricyclic antidepressant, and I read its supplement list with genuine care because so much of it piles onto what the drug already does. Four of the 93 ingredients on file rate major, and those deserve your attention before anything else.”

About Cheken

What is Cheken?

  • Cough and chest congestion
  • Bronchitis and respiratory complaints
  • Digestive upset
  • Mild urinary complaints

Cheken is a leaf from a Chilean evergreen shrub traditionally used for coughs and respiratory complaints. There is very little modern human research to confirm it works or to define a safe dose, so use it cautiously and talk with your pharmacist or doctor first.

Myrceugenia chequen · Myrtaceae · Leaves and essential oil · Tea, tincture, liquid extract, dried leaf

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

Cheken: dosing

There is no established standard dose for Cheken. Because it is not well studied, safe and effective amounts have not been defined.If you choose to use a Cheken product, follow the directions on the label and do not exceed them.

About Protriptyline

What Is Protriptyline Used For?

Brand name: Vivactil

Protriptyline Hydrochloride tablets are used to treat symptoms of mental depression in patients who are under close medical supervision. Because it has activating (energizing) properties rather than sedating ones, it may be especially useful for people with depression who feel withdrawn or have very low energy.
