Drug & supplement interaction

Cilantro + Felodipine

Felodipine brand names: Plendil, Renedil.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Cilantro and Felodipine 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 Felodipine 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

Cilantro and Felodipine

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 Felodipine and Cilantro 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.

Cilantro safety at a glance

Cilantro overall Generally safe Cilantro is generally safe when eaten as a food, but concentrated supplements are less studied.
Pregnancy Use caution Food amounts are likely fine, but medicinal or supplement doses lack safety data and should be avoided.
Breastfeeding Use caution Food amounts are likely fine, but there is not enough information on concentrated supplements.

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

How we checked

Why No Interaction Is Listed for Felodipine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Felodipine is filed under 5 classifications — including calcium channel blockers, antihypertensive drugs, cytochrome p450 3a4 (cyp3a4) substrates. Cilantro has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and photosensitizing drugs (moderate) — and none of Felodipine’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

No Interaction Found — But Data Suggests Cilantro and Felodipine 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. 3 of them are worth acting on rather than waiting out — marked below.

Effects for Felodipine come from the ADVERSE REACTIONS section of its FDA label; effects for Cilantro come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 11,328 voluntary FDA FAERS reports for Felodipine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Felodipine Products Have a Food Rule — Cilantro Should Not Break It

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

Felodipine should regularly be taken either without food or with a light meal (see CLINICAL PHARMACOLOGY, Pharmacokinetics and Metabolism ).

From the Dosage and Administration section of the FDA label we read for Felodipine — 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.

About Cilantro

What is Cilantro?

  • Digestive upset and bloating
  • Antimicrobial support
  • Antioxidant support
  • Heavy metal 'detox' (chelation) claims
  • Culinary flavoring

Cilantro is the leafy part of the Coriandrum sativum plant and is widely eaten as a food, where it is considered safe for most people. While it has antioxidant and antimicrobial properties in lab studies, strong human evidence for any specific health benefit is lacking, and popular 'detox' claims are not well supported. Talk with your pharmacist or doctor before using concentrated cilantro supplements or essential oil.

Coriandrum sativum · Apiaceae · Leaves, stems, seeds (coriander), and essential oil · Fresh herb, dried herb, seeds, capsules, extracts, essential oil, tea

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

Cilantro: dosing

There is no standardized medicinal dose for cilantro. As a food, it is simply used to taste in cooking, which is considered safe for most people.For supplements such as capsules, extracts, or teas, follow the directions on the product label, since strengths vary widely between products. Essential oil is highly concentrated and should not be taken by mouth unless directed by a qualified professional.

Taking Cilantro and Felodipine Together: Common Questions

Is it safe to take Cilantro with Felodipine?
We do not list a known interaction between Cilantro and Felodipine. 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 Cilantro and Felodipine have any of the same side effects?
Yes — our sources link each of them separately to 7 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 Cilantro and Felodipine at the same time of day?
At least one FDA label for a product containing Felodipine 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 Felodipine on its own and move Cilantro 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.
How was the Cilantro and Felodipine combination checked?
Interactions in our licensed database are recorded against drug classes. Felodipine is filed under 5 classifications, and Cilantro has documented interactions with 2 drug classes — none of Felodipine'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 Cilantro interact with any other medications?
Yes. Cilantro has 434 documented drug interactions in our database — Felodipine 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 Felodipine interact with any supplements?
Yes. Felodipine has documented interactions with 232 supplements in our database — Cilantro is not one of them. The Felodipine interaction page linked on this page lists every one, ranked by severity.
