Labdanum + Sevelamer
Sevelamer brand name: Renagel.
We found no known interaction between Labdanum and Sevelamer 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 Sevelamer states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Labdanum and Sevelamer
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 Sevelamer and Labdanum 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 Labdanum at all — not against Sevelamer, 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.
Labdanum safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Sevelamer Products Have a Food Rule — Labdanum Should Not Break It
At least one FDA label for a product containing Sevelamer says to take it with food. If you take Labdanum on an empty stomach out of habit, keep them separate — and take Sevelamer with a meal where the label says to.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Sevelamer 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.
2 DOSAGE AND ADMINISTRATION Starting dose of Renvela is 0.8 or 1.6 grams administered orally three times per day with meals based on serum phosphorus levels for adult patients and based on body surface area (BSA) category for pediatric patients.
From the Dosage and Administration section of the FDA label we read for Sevelamer — 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.
See Every Supplement That Interacts With Sevelamer
This page covers Labdanum only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Sevelamer page lists 18 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 · 10 minor.
From our pharmacist’s overview on the Sevelamer page
“Kidney patients who take sevelamer (Renagel) to control phosphorus have a real reason to pause over this page, and activated charcoal is why. It carries the only major rating here because it can trap medicines in the gut and sharply cut the amount the body actually gets.”

About Labdanum
What is Labdanum?
- Fragrance and perfumery
- Skin care
- Incense and aromatherapy
- Traditional wound and skin remedies
- Relaxation and stress relief
Labdanum is a sticky, fragrant resin from the rockrose plant (Cistus ladanifer) that is used mainly in perfumes, incense, and aromatherapy. There is very little high-quality human research to support any health or medicinal use, so it should be viewed as a scent and cosmetic ingredient rather than a proven remedy.
Cistus ladanifer · Cistaceae · Sticky resin (oleoresin) and essential oil from the leaves and stems · Essential oil, absolute, resin (used in perfumes and incense), and occasionally in skin-care products
An interaction check asks whether these two react with each other — it does not ask whether Labdanum is a good idea for someone in your situation. Here is what our Labdanum record says about it on its own.
Labdanum: dosing
There is no established or standardized medicinal dose for labdanum. It is not commonly sold as an oral supplement, and reliable human dosing information does not exist.If you use a labdanum essential oil or skin product, follow the directions on the label and dilute essential oils as instructed.

About Sevelamer
What Is Sevelamer Used For?
Brand name: Renagel
Sevelamer is used to control serum phosphorus (the level of phosphorus in your blood) in people with chronic kidney disease (CKD) who are on dialysis. High phosphorus is a serious problem for dialysis patients and needs to be managed with medication and diet.
Sevelamer carbonate tablets and Renvela® (sevelamer carbonate) oral suspension are approved for adults and children 6 years of age and older. Sevelamer hydrochloride tablets are indicated for adults with CKD on dialysis; their safety and effectiveness in CKD patients not on dialysis have not been studied.

Sevelamer Is Linked to Lower Levels of One Nutrient
Natural Medicines records Sevelamer as a medicine that can lower these. This is not an interaction with Labdanum — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
