Atlantic Cedar and Dantrolene

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 Dantrolene 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 Dantrolene, 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.

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

From the ADVERSE REACTIONS section of the FDA label for Dantrolene.

From our pharmacist’s overview on the Dantrolene page

“People take dantrolene (Dantrium) for muscle spasticity from multiple sclerosis or spinal cord injury, and the drug already carries a boxed warning for liver injury. That is why its supplement interactions deserve genuine respect.”

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.

Cedrus atlantica · Pinaceae · Wood and essential oil · Essential oil, topical preparations, aromatherapy products, cosmetics and soaps

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 Dantrolene

What Is Dantrolene Used For?

Brand names: Dantrium, Dantrium Intravenous

Dantrolene sodium capsules (Dantrium, Dantrolene Sodium) are used by mouth to control spasticity — painful or disabling muscle stiffness and spasms — caused by upper motor neuron disorders such as spinal cord injury, stroke, cerebral palsy, or multiple sclerosis. They are not used for muscle spasm from arthritis or other rheumatic conditions. Oral capsules are also used before and after surgery to prevent or reduce the risk of malignant hyperthermia in patients known to be susceptible.

For an active malignant hyperthermia crisis — a sudden, dangerous overheating of the muscles triggered by certain anesthetics — the intravenous (IV) forms are given in the hospital. Dantrium Intravenous, Revonto, Ryanodex, and Dantrolene injection are all indicated to treat a malignant hyperthermia crisis and may also be given before surgery to help prevent one in high-risk patients.
