No Known Interaction
Medically reviewed by · Updated June 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Bioenergetics and Erlotinib 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 Erlotinib states a food rule worth keeping to.

Bioenergetics and Erlotinib

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 Erlotinib and Bioenergetics 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 Bioenergetics at all — not against Erlotinib, 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.

Bioenergetics safety at a glance

Bioenergetics overall Not established Because 'bioenergetics' covers many different products and practices, no single safety profile applies.
Pregnancy Use caution Avoid unproven supplement blends or programs during pregnancy unless cleared by your doctor.
Breastfeeding Use caution Safety is not established, so use caution and check with your doctor first.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What Erlotinib’s Own FDA Label Lists

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

  • A stroke or mini-stroke Worth acting on
  • A bowel blockage Worth acting on
  • Severe muscle breakdown Worth acting on
  • Muscle weakness Worth acting on
  • Bleeding in the gut Worth acting on
  • A heart attack Worth acting on
  • Blood clots Worth acting on
  • Pancreatitis Worth acting on
  • Fainting Worth acting on
  • A severe skin reaction Worth acting on

Showing the 10 most notable of 39 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 Erlotinib. Read the label on DailyMed › Where a percentage is shown, it is the share of 12,442 voluntary FDA FAERS reports for Erlotinib that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Bioenergetics’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Bioenergetics side to compare — that is a limit of the record, not a statement that Bioenergetics has no side effects.

How to take them

Some Erlotinib Products Have a Food Rule — Bioenergetics Should Not Break It

At least one FDA label for a product containing Erlotinib says to take it on an empty stomach. Most supplements — Bioenergetics included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Erlotinib on its own and move Bioenergetics to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Erlotinib 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.

Recommended Dose – NSCLC The recommended daily dose of erlotinib tablets for NSCLC is 150 mg taken on an empty stomach, i.e., at least one hour before or two hours after the ingestion of food.

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

This page covers Bioenergetics only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Erlotinib page lists 18 supplements it has a documented interaction with, worst first, each one explained.

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

By severity: 1 major · 8 moderate · 9 minor.

From our pharmacist’s overview on the Erlotinib page

“Activated charcoal is the entry I would flag first for anyone taking erlotinib (Tarceva), an oral targeted therapy for certain lung cancers. Charcoal can adsorb the drug in the gut and cut how much reaches the bloodstream, and with a cancer pill, less absorbed means less cancer fought.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Bioenergetics is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Bioenergetics reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 27, 2026. The Bioenergetics and Erlotinib records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Bioenergetics

What is Bioenergetics?

  • General wellness and energy
  • Stress and emotional balance
  • Fatigue and low energy
  • Detox or 'energy balancing' programs
  • Complementary support for chronic symptoms

"Bioenergetics" is not a single herb or supplement — it is a broad term used for the study of energy flow in living cells and, separately, for a range of alternative wellness practices and products that claim to balance the body's "energy." There is no standardized product, dose, or strong clinical evidence behind the commercial "bioenergetic" treatments, so be cautious and talk with your pharmacist or doctor before spending money or replacing proven care.

Not applicable — Bioenergetics is not a plant or single substance · Therapy or wellness program; sometimes marketed with supplement blends, drops, or devices

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

Bioenergetics: dosing

There is no standardized or evidence-based dose for "bioenergetics," because it is not a single substance. Any dosing instructions come from the individual product's maker, not from established clinical research.If you choose to try a product labeled "bioenergetic," follow the directions on the label and do not exceed them. More importantly, bring the product to your pharmacist so they can review the actual ingredients and check for safety concerns.

About Erlotinib

What Is Erlotinib Used For?

Brand name: Tarceva

Erlotinib tablets are used to treat metastatic non-small cell lung cancer (NSCLC) in patients whose tumors carry specific gene changes — EGFR exon 19 deletions or exon 21 (L858R) mutations — confirmed by an FDA-approved test. It can be used as a first-line treatment, as maintenance therapy, or after at least one prior chemotherapy has stopped working.

Erlotinib tablets are also used for the first-line treatment of locally advanced, unresectable, or metastatic pancreatic cancer — but only in combination with another chemotherapy drug called gemcitabine. Erlotinib is not recommended alongside platinum-based chemotherapy regimens.

Most-Reported Side Effects for Erlotinib

From FAERS, the FDA’s public side-effect reporting system (12,441 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 1,339 reports
Rash 1,317 reports
Malignant neoplasm progression 890 reports

Taking Bioenergetics and Erlotinib Together: Common Questions

Is it safe to take Bioenergetics with Erlotinib?
We do not list a known interaction between Bioenergetics and Erlotinib. 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.
Should I take Bioenergetics and Erlotinib at the same time of day?
At least one FDA label for a product containing Erlotinib says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Erlotinib on its own and move Bioenergetics to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Does Erlotinib interact with any supplements?
Yes. Erlotinib has documented interactions with 18 supplements in our database — Bioenergetics is not one of them. The Erlotinib interaction page linked on this page lists every one, ranked by severity.
