The bottom line No known interaction

We found no known interaction between Kohlrabi 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.

Kohlrabi 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 Kohlrabi 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 Kohlrabi at all — not against Cefprozil, 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

What Cefprozil’s Own FDA Label Lists

This is not an interaction — none of it involves Kohlrabi. These are the most notable effects listed in the ADVERSE REACTIONS section of Cefprozil’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both.

  • Stomach pain
  • Diarrhea
  • Vomiting
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Cefprozil. Read the label on DailyMed › 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. Kohlrabi’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Kohlrabi side to compare — that is a limit of the record, not a statement that Kohlrabi has no side effects.

See Every Supplement That Interacts With Cefprozil

This page covers Kohlrabi 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.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Kohlrabi is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Kohlrabi reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Kohlrabi and Cefprozil records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Kohlrabi

What is Kohlrabi?

  • General nutrition
  • Source of vitamin C
  • Source of dietary fiber
  • Digestive health
  • Antioxidant support

Kohlrabi is a nutritious cabbage-family vegetable that is a good source of vitamin C, fiber, and antioxidants. It is best thought of as a healthy food rather than a medicinal supplement, and there is little clinical research testing it for treating any specific disease. For most people, eating kohlrabi as part of a balanced diet is safe and beneficial.

Brassica oleracea var. gongylodes · Brassicaceae · Swollen stem (bulb), leaves · Fresh vegetable (raw or cooked), juice, salads

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

Kohlrabi: dosing

There is no established medicinal dose for kohlrabi because it is a food, not a standardized supplement. There is not enough research to recommend any specific concentrated dose.

From our Kohlrabi monograph — the full record covers uses, side effects and every documented interaction.

About Cefprozil

What Is Cefprozil Used For?

Brand name: Cefzil

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.

Most-Reported Side Effects for Cefprozil

From FAERS, the FDA’s public side-effect reporting system (780 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Chronic kidney disease 89 reports
Drug hypersensitivity 73 reports
Cough 64 reports
Acute kidney injury 59 reports
Dyspnea 59 reports
