Beta-methylphenethylamine (bmpea) + Tolnaftate
Tolnaftate brand name: Tinactin.
We found no known interaction between Beta-methylphenethylamine (bmpea) and Tolnaftate 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.
Beta-methylphenethylamine (bmpea) and Tolnaftate
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 Tolnaftate and Beta-methylphenethylamine (bmpea) 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.
Beta-methylphenethylamine (bmpea) safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Tolnaftate
Interactions in our licensed database are recorded against drug classes, not just single drug names. Tolnaftate is filed under 2 classifications — antifungals, oral drugs. Beta-methylphenethylamine (bmpea) has documented interactions with 3 drug classes — the most serious being cytochrome p450 2d6 (cyp2d6) substrates (moderate), cytochrome p450 3a4 (cyp3a4) substrates (moderate) and stimulant drugs (moderate) — and none of Tolnaftate’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.
Beta-methylphenethylamine (bmpea) Does Interact With Other Medications
Beta-methylphenethylamine (bmpea) has 813 moderate known drug interactions in our database — Tolnaftate isn’t one of them. If you take anything else, check it against the full list below.

See Every Supplement That Interacts With Tolnaftate

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).
By severity: 1 major · 7 moderate · 12 minor.
From our pharmacist’s overview on the Tolnaftate page
“For anyone using tolnaftate (Tinactin), the antifungal in athlete's foot creams and sprays, activated charcoal is the interaction to understand before all others. It holds the only major rating among the 20 ingredients on file, since charcoal binds many medicines and can lower how much reaches the body, even drugs not given by mouth.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions.
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Beta-methylphenethylamine (bmpea) reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Beta-methylphenethylamine (bmpea) and Tolnaftate records this page draws on were last updated July 10, 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 Beta-methylphenethylamine (bmpea)
What is Beta-methylphenethylamine (bmpea)?
- Weight loss
- Pre-workout energy
- Athletic performance
- Appetite suppression
- Mental focus
Beta-methylphenethylamine (BMPEA) is a synthetic stimulant chemically similar to amphetamine that has been found in some weight-loss and sports supplements, often without being clearly listed on the label. It is not an approved or well-studied dietary ingredient, and regulators have warned that it may carry real cardiovascular risks. Because of safety concerns and the lack of human research, it is best avoided.
Synthetic chemical; also reported as a constituent of some Acacia species · Capsules, tablets, and powders sold as pre-workout, weight-loss, or 'energy' supplements
An interaction check asks whether these two react with each other — it does not ask whether Beta-methylphenethylamine (bmpea) is a good idea for someone in your situation. Here is what our Beta-methylphenethylamine (bmpea) record says about it on its own.
Beta-methylphenethylamine (bmpea): dosing
There is no established or recommended dose for BMPEA, and no safe dose has been determined through research. It is not an approved ingredient, so any amount in a supplement is unregulated and may not match what the label says.We do not recommend taking BMPEA.

About Tolnaftate
What Is Tolnaftate Used For?
Brand name: Tinactin
Tolnaftate treats common fungal skin infections — specifically athlete's foot (tinea pedis), jock itch (tinea cruris), and ringworm (tinea corporis). It also helps relieve the itching, cracking, burning, scaling, redness, and soreness that come with these infections.
Several products also help prevent athlete's foot from coming back with regular daily use. Note that tolnaftate is not effective on the scalp or nails — though some patch products are applied around the nail and cuticle area to address skin surrounding the nail.
Most-Reported Side Effects for Tolnaftate
From FAERS, the FDA’s public side-effect reporting system (1,403 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
