Herb Robert + Ofloxacin

Ofloxacin brand names: Oflox, Floxin, Floxin Injection, Floxin Otic.

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 Herb Robert and Ofloxacin 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 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.

Herb Robert and Ofloxacin

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 Ofloxacin and Herb Robert 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Herb Robert at all — not against Ofloxacin, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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

No Interaction Found — But Data Suggests Herb Robert and Ofloxacin 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 skin reaction Worth acting on Additional detail

    “Topically, Herb Robert can cause contact dermatitis. There are at least two cases of known contact sensitization of elderly individuals to Herb Robert through gardening. One case resulted in an erythema multiforme-like eruption requiring treatment with steroids.”

Effects for Ofloxacin come from the ADVERSE REACTIONS section of its FDA label; effects for Herb Robert come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 7,263 voluntary FDA FAERS reports for Ofloxacin 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.

Overlapping uses

What Ofloxacin Is Prescribed For, and What Herb Robert Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Ofloxacin is a prescription medicine with approved uses on its FDA label. Herb Robert is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Ofloxacin is prescribed for: Ofloxacin is used in several different forms, each approved for specific infections. The otic (ear) solution treats outer ear infections (otitis externa) in patients 6 months and older, chronic middle ear infections with a ruptured eardrum (chronic suppurative otitis media) in patients 12 and older, and acute middle ear infections in children 1 year and older who have ear tubes. The ophthalmic (eye) solution — including the brand Ocuflox — treats bacterial conjunctivitis (pink eye) and bacterial corneal ulcers. Ofloxacin oral tablets treat adults with mild to moderate bacterial infections including community-acquired pneumonia, skin and skin structure infections, gonorrhea, chlamydial infections of the urethra or cervix, mixed urethral/cervical infections, and acute pelvic inflammatory disease.

The oral tablet is also used for acute bacterial exacerbations of chronic bronchitis and uncomplicated cystitis, but only when no other treatment options are available, due to serious risk concerns with this drug class.

Herb Robert has been studied for:

  • Otitis media studied, not established Herb Robert has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Herb Robert for otitis media

    Clinical research of an herbal mixture containing the essential oils of Herb Robert, clove, and lavender shows that placing 3 drops in the ear every 12 hours for one week improves otitis media symptoms including pain, tenderness, itching, edema, and discharge when compared with baseline. These improvements are similar to those achieved with ciprofloxacin 0.3% otic drops.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Ofloxacin on your own; if you are taking Herb Robert for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Herb Robert

What is Herb Robert?

Herb Robert
  • Digestive upset
  • Wound and skin care
  • Sore throat and mouth irritation
  • Respiratory complaints
  • General 'detox' tonic

Herb Robert is a traditional European herb used for digestion, wounds, and minor inflammation, but there is very little human research to confirm it works for any condition. It is likely fine in small amounts as a tea for most healthy adults, but its safety has not been well studied. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Geranium robertianum · Geraniaceae · Above-ground parts (leaves, stems, and flowers) · Tea, tincture, dried herb, capsules, fresh poultice

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

Herb Robert: dosing

There is no established, standardized dose for Herb Robert. Traditional use involved brewing a small amount of the dried herb as a tea or applying crushed fresh leaves to the skin, but these amounts were not measured in a consistent, science-based way.If you choose to use a commercial product, follow the directions on the label and do not exceed the recommended amount.

Taking Herb Robert and Ofloxacin Together: Common Questions

Is it safe to take Herb Robert with Ofloxacin?
We do not list a known interaction between Herb Robert and Ofloxacin. 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 Herb Robert and Ofloxacin have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
Are Herb Robert and Ofloxacin used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Herb Robert in each. That is a conversation for your prescriber, especially if Ofloxacin is being adjusted to a target.
Does Ofloxacin interact with any supplements?
Yes. Ofloxacin has documented interactions with 145 supplements in our database — Herb Robert is not one of them. The Ofloxacin interaction page linked on this page lists every one, ranked by severity.
