Drug & supplement interaction

Sorrel + Cefprozil

Cefprozil brand name: Cefzil.

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 Sorrel and Cefprozil 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.

Sorrel and Cefprozil

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 Cefprozil and Sorrel 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.

Pharmacist analysis

Sorrel has few documented, clinically significant, drug interactions. Preliminary research in animals indicates it may interact with antiplatelet drugs and drugs that are a substrate for transporter proteins known as OATPs (Organic Anion Transporting Polypeptides).

It is unlikely sorrel has clinically significant drug interactions, and there is no known drug interaction between the drug in this monograph and sorrel. As always however, be sure to let your doctor know about all the medications you are taking so you can be appropriately monitored.

How we checked

Why No Interaction Is Listed for Cefprozil

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cefprozil is filed under 6 classifications — including organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates, antibiotic drugs. Sorrel has documented interactions with 3 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), fexofenadine (allegra) (moderate) and organic anion-transporting polypeptide substrates (oatp) (moderate) — and none of Cefprozil’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

No Interaction Found — But Data Suggests Sorrel and Cefprozil May Share a Side Effect

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.

  • Nausea Additional detail

    Cefprozil

    Listed in the ADVERSE REACTIONS section of the FDA label for Cefprozil. Read the label on DailyMed ›

Reported for Sorrel but not commonly for Cefprozil: kidney problems, a stuffy or runny nose, passing urine more often and wheezing.

Effects for Cefprozil come from the ADVERSE REACTIONS section of its FDA label; effects for Sorrel come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 780 voluntary FDA FAERS reports for Cefprozil 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 Cefprozil Is Prescribed For, and What Sorrel Has Been Studied For

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

Cefprozil is prescribed for: Cefprozil tablets and oral suspension are both used to treat mild to moderate bacterial infections in adults and children. Approved uses include pharyngitis/tonsillitis (strep throat), acute sinusitis, otitis media (ear infections), acute bacterial exacerbation of chronic bronchitis, and uncomplicated skin and skin-structure infections. Cefprozil tablets are also approved for secondary bacterial infection of acute bronchitis. Because antibiotic resistance is a real concern, cefprozil should only be used when the infection is proven or strongly suspected to be caused by bacteria that respond to it.

Sorrel has been studied for:

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

    Sorrel for bronchitis

    Although there is interest in using oral sorrel for bronchitis, there is insufficient reliable information about the clinical effects of sorrel for this condition.

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 Cefprozil on your own; if you are taking Sorrel for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Cefprozil

This page covers Sorrel only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefprozil page lists 60 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Siberian Cocklebur (major), African Wild Potato (moderate) and Aristolochia (moderate).

By severity: 3 major · 46 moderate · 11 minor.

From our pharmacist’s overview on the Cefprozil page

“Cefprozil (Cefzil) is a cephalosporin antibiotic, usually a short course for ear, sinus, throat, or skin infections, and three of the 60 supplements on this list warrant real caution even for a week of pills. Activated charcoal can bind the drug and pull it out of your system before it works.”

About Sorrel

What is Sorrel?

Sorrel
  • Sinus and respiratory congestion
  • Digestive upset
  • Fever
  • Skin conditions and inflammation
  • Antioxidant support

Sorrel is a tangy, leafy herb used in cooking and traditional medicine, often for congestion, digestion, and inflammation. Solid human evidence for any health benefit is limited, and its high oxalate content means it should be used in moderation, especially by people prone to kidney stones.

Rumex acetosa · Polygonaceae · Leaves (and sometimes whole aerial parts) · Fresh leaves in cooking, tea, dried herb, tincture, and as an ingredient in some herbal combination products

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

Sorrel: dosing

There is no well-established standardized medicinal dose for sorrel. As a food, it is used in normal culinary amounts.When sorrel appears in herbal supplement products, the amount varies by brand. Follow the directions on the product label and do not exceed the recommended dose. Because of the oxalate concern, it is wise to avoid taking large amounts over long periods.

Taking Sorrel and Cefprozil Together: Common Questions

Is it safe to take Sorrel with Cefprozil?
We do not list a known interaction between Sorrel and Cefprozil. 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 Sorrel and Cefprozil have any of the same side effects?
Yes — our sources link each of them separately to one 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 Sorrel and Cefprozil 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 Sorrel in each. That is a conversation for your prescriber, especially if Cefprozil is being adjusted to a target.
How was the Sorrel and Cefprozil combination checked?
Interactions in our licensed database are recorded against drug classes. Cefprozil is filed under 6 classifications, and Sorrel has documented interactions with 3 drug classes — none of Cefprozil'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 Sorrel interact with any other medications?
Yes. Sorrel has 169 documented drug interactions in our database — Cefprozil 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 Cefprozil interact with any supplements?
Yes. Cefprozil has documented interactions with 60 supplements in our database — Sorrel is not one of them. The Cefprozil interaction page linked on this page lists every one, ranked by severity.
