Drug & supplement interaction

Dill + Prednisone

Prednisone brand names: Deltasone, Cortan, Orasone, Prednisone, Prednicen-M, and others.

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 Dill and Prednisone 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 Prednisone 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

Dill and Prednisone

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 Prednisone and Dill 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.

Dill safety at a glance

Dill overall Generally safe Generally safe in the amounts used in food.
Pregnancy Possibly Unsafe When used in medicinal amounts. Dill seed is used to stimulate menstrual flow. Theoretically, dill seed might adversely affect pregnancy. Read the full pregnancy detail
Breastfeeding Use caution Food amounts are likely fine, but the safety of medicinal doses is not well studied.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Prednisone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Prednisone is filed under 7 classifications — including corticosteroids, cytochrome p450 2c19 (cyp2c19) inducers, immunosuppressants. Dill has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and lithium (moderate) — and none of Prednisone’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 Dill and Prednisone 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. One of them is worth acting on rather than waiting out — marked below.

  • A severe allergic reaction Worth acting on Additional detail

    Dill

    “Orally, there are case reports of individuals allergic to dill. In one case, symptoms, including swelling around the eyes, itching, rash, and chapped lips, occurred after a delay of 12 hours. In another case, immediate symptoms of anaphylaxis, as well as vomiting and diarrhea, occurred following intake and inhalation of foods cooked with dill.

    Topically, dill has resulted in contact dermatitis.”

Reported for Dill but not commonly for Prednisone: sun sensitivity and itching.

Effects for Prednisone come from the ADVERSE REACTIONS section of its FDA label; effects for Dill come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 491,135 voluntary FDA FAERS reports for Prednisone 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 Prednisone Products Have a Food Rule — Dill Should Not Break It

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

DOSAGE AND ADMINISTRATION Gastric irritation may be reduced if taken before, during, or immediately after meals or with food or milk.

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

This page covers Dill only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Prednisone page lists 208 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), Lily-of-the-valley (major), St. John's Wort (major) and Acacia Rigidula (moderate).

By severity: 4 major · 168 moderate · 36 minor.

From our pharmacist’s overview on the Prednisone page

“Prednisone (Deltasone) suppresses the immune system to control inflammation, and that mechanism shapes most of what can go wrong on this 208-ingredient list, which I read as one to approach carefully rather than casually. Four entries rate major.”

About Dill

What is Dill?

  • Digestive upset and gas
  • Colic in infants (traditional)
  • Stimulating appetite
  • Bad breath
  • Menstrual discomfort

Dill is a common culinary herb that has long been used in traditional medicine for digestive complaints, but solid human evidence for any medicinal use is limited. It is generally considered safe in normal food amounts, while concentrated supplements or essential oil should be used with caution and discussed with a pharmacist or doctor.

Anethum graveolens · Apiaceae · Leaves (dill weed), seeds, and essential oil · Fresh or dried herb, seeds, tea, essential oil, capsules/extracts

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

Dill: dosing

There is no official or standardized medicinal dose for dill. As a food and seasoning, it is used freely to taste. As a tea, the seeds are sometimes steeped in hot water.For dill supplements, capsules, or extracts, the best advice is to follow the directions on the product label, since strength varies between products.

Taking Dill and Prednisone Together: Common Questions

Is it safe to take Dill with Prednisone?
We do not list a known interaction between Dill and Prednisone. 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 Dill and Prednisone have any of the same side effects?
Yes — our sources link each of them separately to 5 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 Dill and Prednisone at the same time of day?
At least one FDA label for a product containing Prednisone says to take it with food. If you take Dill on an empty stomach out of habit, keep them separate and take Prednisone with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Prednisone products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Dill and Prednisone combination checked?
Interactions in our licensed database are recorded against drug classes. Prednisone is filed under 7 classifications, and Dill has documented interactions with 2 drug classes — none of Prednisone'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 Dill interact with any other medications?
Yes. Dill has 87 documented drug interactions in our database — Prednisone 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 Prednisone interact with any supplements?
Yes. Prednisone has documented interactions with 208 supplements in our database — Dill is not one of them. The Prednisone interaction page linked on this page lists every one, ranked by severity.
