Drug & supplement interaction

Frankincense + Duloxetine

Duloxetine brand names: Cymbalta, Drizalma Sprinkle, Irenka.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Frankincense and Duloxetine 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.

Frankincense and Duloxetine

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 Duloxetine and Frankincense 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 Frankincense at all — not against Duloxetine, 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 Frankincense Itself Has Been Linked To

This is not an interaction — nothing below involves Duloxetine. It is the side-effect record for Frankincense on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Frankincense, this list is the first place to look.

  • Itching Additional detail

    “Topically and by inhalation, frankincense essential oil seems to be well tolerated. For information on the safety of frankincense when used orally, see the Boswellia serrata monograph.

    Most Common Adverse Effects:

    Topically: Dermatitis, irritation, itching.”

    Frankincense · Natural Medicines adverse-effect record, reported in dermatitis.

  • A skin rash Additional detail

    “Frankincense has been rarely reported to cause allergic skin reactions. In one case report, a 68-year-old female with no history of atopy presented with contact dermatitis after frequent diffusion of a specific frankincense essential oil product (Young Living Essential Oils) and application to the pillow each night. The patient also applied various other creams to the face.”

Everything above comes from the Natural Medicines adverse-effect record for Frankincense — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Duloxetine’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Duloxetine column appears here.

Overlapping uses

What Duloxetine Is Prescribed For, and What Frankincense Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Duloxetine is a prescription medicine with approved uses on its FDA label. Frankincense is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Duloxetine is prescribed for: Duloxetine delayed-release capsules treat major depressive disorder (MDD) and generalized anxiety disorder (GAD) in adults. They also manage diabetic peripheral neuropathic pain (nerve pain from diabetes), fibromyalgia, and chronic musculoskeletal pain (such as chronic low back pain and pain from osteoarthritis) in adults. GAD is also approved in pediatric patients 7 years and older for Cymbalta, Drizalma Sprinkle, and certain duloxetine delayed-release capsule products. Fibromyalgia is approved in patients 13 years and older for Cymbalta and some duloxetine delayed-release capsule products.

Frankincense has been studied for:

  • Back pain studied, not established Frankincense has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Frankincense for back pain

    Topical frankincense has only been evaluated in combination with other ingredients; its effect when used alone is unclear.

  • Osteoarthritis studied, not established Frankincense has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Frankincense for osteoarthritis

    It is unclear if topical frankincense is beneficial in patients with osteoarthritis.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Duloxetine on your own; if you are taking Frankincense for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Frankincense

What is Frankincense?

Frankincense
  • Joint pain and osteoarthritis
  • Inflammation
  • Digestive complaints
  • Asthma and breathing problems
  • Calming aromatherapy

Frankincense is the aromatic resin of the Boswellia tree and is best known for its boswellic acids, which may help with inflammation and joint pain. Early research is promising for conditions like osteoarthritis, but the evidence is still limited and dosing is not standardized. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Boswellia serrata · Burseraceae · Oleo-gum-resin from the tree bark; essential oil distilled from the resin · Capsules and tablets (often standardized Boswellia extract), resin, essential oil for aromatherapy, topical creams

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

Frankincense: dosing

There is no official, standardized dose of frankincense. Studies have used different Boswellia extracts standardized to varying amounts of boswellic acids, so it is hard to compare products directly.The safest approach is to follow the directions on the product label and choose a reputable brand that lists its boswellic acid content. Essential oils are for inhalation or diluted topical use only and should never be taken by mouth.

Taking Frankincense and Duloxetine Together: Common Questions

Is it safe to take Frankincense with Duloxetine?

Are Frankincense and Duloxetine used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Frankincense in each. That is a conversation for your prescriber, especially if Duloxetine is being adjusted to a target.
Does Duloxetine interact with any supplements?
Yes. Duloxetine has documented interactions with 132 supplements in our database — Frankincense is not one of them. The Duloxetine interaction page linked on this page lists every one, ranked by severity.
