Atlantic Cedar 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 Atlantic Cedar 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 Atlantic Cedar at all — not against Tolnaftate, 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.

Atlantic Cedar safety at a glance

Atlantic Cedar overall Use caution Generally used topically in diluted form; the undiluted oil can irritate skin and should not be taken by mouth.
Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety has not been established, so avoid use while breastfeeding.

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

See Every Supplement That Interacts With Tolnaftate

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

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.”

About Atlantic Cedar

What is Atlantic Cedar?

Atlantic Cedar
  • Hair loss (alopecia areata)
  • Insect repellent
  • Antimicrobial and antifungal
  • Aromatherapy and relaxation
  • Fragrance in cosmetics and perfumes

Atlantic cedar (Cedrus atlantica) is a tree whose wood and essential oil are used in traditional medicine, mainly applied to the skin and scalp or used as a scent. Human evidence for its health benefits is very limited, and the oil should be used diluted and never swallowed. Talk to a pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or treating a child.

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

Atlantic Cedar: dosing

There is no established standard dose for Atlantic cedar. It is not meant to be taken by mouth, and most use is topical or as a scent.If you use a product containing the oil, follow the directions on the label and dilute the essential oil in a carrier oil before applying it to skin.

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.

Fatigue 88 reports
Nausea 86 reports
Dyspnea 80 reports
Diarrhea 73 reports
Anxiety 69 reports
