The bottom line No known interaction

We found no known interaction between Marsh Labrador Tea and Romosozumab-Aqqg 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 Romosozumab-Aqqg states a food rule worth keeping to.

Interaction report

Marsh Labrador Tea and Romosozumab-Aqqg

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 Romosozumab-Aqqg and Marsh Labrador Tea 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.

What to actually watch for

What Marsh Labrador Tea Itself Has Been Linked To

This is not an interaction — nothing below involves Romosozumab-Aqqg. It is the side-effect record for Marsh Labrador Tea on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Marsh Labrador Tea, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Seizures Worth acting on Additional detail

    “Orally, large amounts of marsh Labrador tea can cause poisoning due to its ledol constituent (2). The essential oil of marsh Labrador tea can cause severe irritation of the gastrointestinal tract, vomiting, diarrhea, irritation and damage to the kidneys and urinary tract, heavy perspiration, myalgias, and arthralgias.”

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

How to take them

Some Romosozumab-Aqqg Products Have a Food Rule — Marsh Labrador Tea Should Not Break It

At least one FDA label for a product containing Romosozumab-Aqqg says to take it on an empty stomach. Most supplements — Marsh Labrador Tea included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Romosozumab-Aqqg on its own and move Marsh Labrador Tea to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Romosozumab-Aqqg 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.

Allow EVENITY to sit at room temperature for at least 30 minutes before injecting.

From the Dosage and Administration section of the FDA label we read for Romosozumab-Aqqg — where that label names a specific product, the instruction is that product's. See the Romosozumab-Aqqg drug page ›

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.

About Marsh Labrador Tea

What is Marsh Labrador Tea?

Marsh Labrador Tea
  • Colds and respiratory complaints
  • Cough and congestion
  • Mild aches and joint discomfort
  • Topical relief of skin irritation, swelling, and insect bites
  • Traditional use as a diuretic

Marsh Labrador tea is a bog-growing shrub used in folk medicine for coughs, colds, and skin problems, but high-quality human evidence for any use is lacking. Because it contains grayanotoxins (andromedotoxin) that can be poisonous, it is not considered safe for routine use, and pregnant or breastfeeding people should avoid it.

Rhododendron tomentosum · Ericaceae · Leaves and flowering twigs (and an essential oil distilled from them) · Tea (infusion), essential oil, topical preparations

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

Marsh Labrador Tea: dosing

There is no established safe or standardized dose for Marsh Labrador tea. Because the plant naturally contains toxic grayanotoxins, even traditional preparations carry risk, and stronger or longer brews increase that risk.If you choose to use a commercial product, follow the directions on the label exactly and do not exceed them. Never assume that "natural" means harmless.

About Romosozumab-aqqg Injection

What Is Romosozumab-aqqg Injection Used For?

Brand name: Evenity

Evenity (romosozumab-aqqg) is approved to treat osteoporosis in postmenopausal women who are at high risk for breaking a bone. That includes women who have already had an osteoporotic fracture, have multiple risk factors for fractures, or have not responded to — or cannot tolerate — other osteoporosis treatments.

Treatment with Evenity is limited to 12 monthly doses. If continued bone protection is needed after that course, a prescriber will typically recommend switching to a different type of osteoporosis medication called an anti-resorptive agent.

Taking Marsh Labrador Tea and Romosozumab-Aqqg Together: Common Questions

Is it safe to take Marsh Labrador Tea with Romosozumab-Aqqg?
We do not list a known interaction between Marsh Labrador Tea and Romosozumab-Aqqg. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Should I take Marsh Labrador Tea and Romosozumab-Aqqg at the same time of day?
At least one FDA label for a product containing Romosozumab-Aqqg says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Romosozumab-Aqqg on its own and move Marsh Labrador Tea to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.

Yes. Marsh Labrador Tea has 248 documented drug interactions in our database — Romosozumab-Aqqg is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
