No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Linden and Metoprolol 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 Metoprolol states a food rule worth keeping to.

Linden and Metoprolol

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 Metoprolol and Linden 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.

Linden safety at a glance

Linden overall Use caution Generally well tolerated as a tea, but human safety data are limited.
Pregnancy Avoid Not enough safety information, so avoiding it is the safer choice.
Breastfeeding Use caution Safety is not well studied; check with your doctor before use.

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

How we checked

Why No Interaction Is Listed for Metoprolol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Metoprolol is filed under 6 classifications — including beta-blockers, antihypertensive drugs, cytochrome p450 2d6 (cyp2d6) substrates. Linden has documented interactions with 1 drug class — the most serious being lithium (moderate) — and none of Metoprolol’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Linden Itself Has Been Linked To

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

  • Hives / An allergic reaction Worth acting on Additional detail

    “Orally, there is one case report of allergic reaction to linden pollen in a linden flower tea (12). Topically, there is one case report of contact urticaria following the use of a linden extract-containing shampoo (12).”

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

How to take them

Some Metoprolol Products Have a Food Rule — Linden Should Not Break It

At least one FDA label for a product containing Metoprolol says to take it with food. If you take Linden on an empty stomach out of habit, keep them separate — and take Metoprolol 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 Metoprolol 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.

Administer once daily with food or after a meal.

From the Dosage and Administration section of the FDA label we read for Metoprolol — where that label names a specific product, the instruction is that product's. See the Metoprolol 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.

From our pharmacist’s overview on the Metoprolol page

“With metoprolol (Lopressor, Toprol XL), a beta-blocker for high blood pressure and heart problems, these interactions deserve genuine care, starting with the five rated major. Most entries pull blood pressure one way or the other: many supplements add to metoprolol's lowering effect and can drop pressure too far, while a few, tyramine…”

About Linden

What is Linden?

  • Anxiety and stress
  • Trouble sleeping
  • Colds and flu symptoms
  • Cough and sore throat
  • Mild digestive upset
  • Promoting sweating during fever

Linden (also called lime flower) is a traditional herbal tea long used to calm nerves, ease cold symptoms, and support restful sleep. Strong human evidence for these uses is lacking, but the flowers are generally considered safe as an occasional tea for most healthy adults. Talk with your pharmacist or doctor before using it regularly, especially during pregnancy, breastfeeding, or if you have a health condition.

Tilia cordata, Tilia platyphyllos · Malvaceae · Dried flowers (and bracts), sometimes leaves · Tea (infusion), tincture, liquid extract, capsules

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

Linden: dosing

There is no official standardized dose for linden. Traditionally it is taken as a tea made by steeping a small amount of the dried flowers in hot water, often once or a few times a day.Because products vary in strength, the best approach is to follow the directions on the product label.

From our Linden monograph — the full record covers uses, side effects and every documented interaction.

About Metoprolol

What Is Metoprolol Used For?

Brand names: Lopressor, Toprol XL

Metoprolol is used for several heart and blood pressure conditions. Which ones depend on the product you take.

  • High blood pressure (hypertension): metoprolol tartrate tablets, metoprolol succinate extended-release tablets (including Toprol-XL), and Lopressor tablets lower blood pressure. This lowers the risk of strokes and heart attacks.
  • Angina pectoris: these same tablet products are also used for angina.
  • Heart failure: metoprolol succinate extended-release tablets (including Toprol-XL) are used in heart failure. They reduce the risk of cardiovascular death and heart failure hospitalizations.
  • Heart attack: metoprolol tartrate tablets and Lopressor tablets reduce the risk of cardiovascular death after a definite or suspected acute heart attack, in stable patients, when used with intravenous metoprolol. Metoprolol tartrate injection is used in the hospital for the same purpose, followed by oral metoprolol.

Taking Linden and Metoprolol Together: Common Questions

Is it safe to take Linden with Metoprolol?
We do not list a known interaction between Linden and Metoprolol. 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 Linden and Metoprolol at the same time of day?
At least one FDA label for a product containing Metoprolol says to take it with food. If you take Linden on an empty stomach out of habit, keep them separate and take Metoprolol with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Metoprolol products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Linden and Metoprolol combination checked?
Interactions in our licensed database are recorded against drug classes. Metoprolol is filed under 6 classifications, and Linden has documented interactions with 1 drug class — none of Metoprolol's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Linden interact with any other medications?
Yes. Linden has 1 documented drug interaction in our database — Metoprolol is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Metoprolol interact with any supplements?
Yes. Metoprolol has documented interactions with 183 supplements in our database — Linden is not one of them. The Metoprolol interaction page linked on this page lists every one, ranked by severity.
