Drug & supplement interaction

Bacopa + Metoprolol

Metoprolol brand names: Lopressor, Toprol XL.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Bacopa 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, 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.

Interaction report

Bacopa 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 Bacopa 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.

Bacopa safety at a glance

Bacopa overall Use caution Generally well tolerated in studies, but quality and long-term safety data are limited.
Pregnancy Avoid Not enough safety information, so it is best to avoid during pregnancy.
Breastfeeding Avoid Not enough safety information, so it is best to avoid while breastfeeding.

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. Bacopa has documented interactions with 8 drug classes — the most serious being anticholinergic drugs (moderate), cevimeline (evoxac) (moderate) and cholinergic drugs (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.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Bacopa and Metoprolol May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

How to take them

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

At least one FDA label for a product containing Metoprolol says to take it with food. If you take Bacopa 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. 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 Metoprolol

This page covers Bacopa only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Metoprolol page lists 183 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Indian Snakeroot (major) and Tyramine (major).

By severity: 5 major · 152 moderate · 26 minor.

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 Bacopa

What is Bacopa?

Bacopa
  • Memory and cognitive support
  • Anxiety and stress
  • ADHD symptoms
  • Age-related memory decline
  • General brain health

Bacopa is an Ayurvedic herb most often used for memory and thinking. Some small studies suggest it may modestly help memory when taken regularly for several weeks, but the evidence is limited and quality varies. It is generally well tolerated but can cause stomach upset, and it should be avoided in pregnancy and breastfeeding due to a lack of safety data.

Bacopa monnieri · Plantaginaceae · Whole plant (mainly leaves and stems) · Capsules, tablets, powder, liquid extracts, and standardized extracts (often standardized to bacosides)

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

Bacopa: dosing

There is no official, universally agreed-upon dose for bacopa. Many studies have used standardized extracts taken daily for several weeks, but the right dose can depend on the specific product and how it is standardized (often to bacosides).The best approach is to follow the directions on the product label and not exceed the recommended amount. Because effects on memory, if any, tend to build slowly, it may take several weeks to notice a change.

About Metoprolol

What Is Metoprolol Used For?

Brand names: Lopressor, Toprol XL

Metoprolol is used to treat several heart and blood pressure conditions. Metoprolol succinate extended-release tablets (including Toprol-XL) are approved for high blood pressure, angina pectoris (chest pain from the heart), and heart failure. Metoprolol tartrate tablets (including Lopressor) are approved for high blood pressure, angina, and — when used alongside intravenous metoprolol — to reduce the risk of cardiovascular death after a definite or suspected heart attack.

Metoprolol tartrate injection (intravenous form) is used in hemodynamically stable patients with a definite or suspected acute heart attack to reduce cardiovascular death, and is followed by oral metoprolol therapy. Lowering blood pressure with metoprolol reduces the risk of strokes and heart attacks.

Most-Reported Side Effects for Metoprolol

Taking Bacopa and Metoprolol Together: Common Questions

Is it safe to take Bacopa with Metoprolol?
We do not list a known interaction between Bacopa 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.
Do Bacopa and Metoprolol have any of the same side effects?
Yes — our sources link each of them separately to 10 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Bacopa 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 Bacopa 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 Bacopa and Metoprolol combination checked?
Interactions in our licensed database are recorded against drug classes. Metoprolol is filed under 6 classifications, and Bacopa has documented interactions with 8 drug classes — 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 Bacopa interact with any other medications?
Yes. Bacopa has 930 documented drug interactions 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 — Bacopa is not one of them. The Metoprolol interaction page linked on this page lists every one, ranked by severity.
