HelloPharmacist Bottom Line
Our Pharmacist Explains
What is this? The interaction data in the HelloPharmacist supplement database is licensed from Natural Medicines Pro by TRC Healthcare (Therapeutic Research). HelloPharmacist pharmacists often add our own analysis and context on top of that licensed data — such as this Bottom Line summary and the notes on individual interaction pages — and any such commentary is noted as ours.

A course of ceftazidime, an injectable antibiotic for serious infections, often comes with a probiotic to steady the gut, and that pairing is most of this list. Twenty-seven of the 37 ingredients on file are probiotics or fermented milk products whose live organisms the antibiotic can kill, blunting the supplement rather than the drug. Nothing rates major, with 36 moderate entries and one minor, so these combinations are manageable if you know which effects deserve an eye.

The rest splits two ways. Six ingredients may lower the seizure threshold, relevant because ceftazidime itself can provoke seizures at high blood levels, especially when kidney function is reduced. A few others use the same kidney transporters (OAT1 and OAT3) that clear the drug and could nudge levels either way. Spacing probiotics well apart from antibiotic doses handles the largest group, and the seizure and transporter entries are worth raising with your pharmacist.

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.
  • Each entry links to a full report with the clinical detail, likelihood, evidence level, and citations for that exact combination.
  • Content is reviewed by licensed HelloPharmacist pharmacists — see our data sources and editorial standards.

How Does Our Interaction Checker Work?

Behind every verdict on this page is a category system. Our source database doesn’t document supplement interactions drug-by-drug — it documents them against groups of medications that behave the same way (for example, “drugs processed by the CYP3A4 liver enzyme” or “blood-thinning medications”).

So the check works in three steps: (1) Ceftazidime is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Ceftazidime, and (3) each ingredient keeps its own severity, likelihood, and evidence grades from the underlying record. That’s why one supplement can carry several records for one drug — it may interact through more than one category.

Ceftazidime sits in 4 interaction categories. Open any one to see what the group means:

Antibiotic Drugs 27 ingredients

A pharmacology grouping from our source database: medications in this group share a property that certain supplements are known to interact with, so an interaction documented for the group applies to every drug in it.

Ceftazidime & Supplements: Common Questions

What supplements interact with Ceftazidime?
In our interaction database, 37 supplement and herbal ingredients have an interaction with Ceftazidime on file — 0 rated major, 36 moderate, and 1 minor. That number sounds scarier than it is: severity matters far more than the count, which is why the list on this page is ranked instead of alphabetical. Start at the top. The highest-ranked right now: Bacillus Coagulans, Bacillus Subtilis, Bifidobacterium Animalis Subsp. Lactis.
Which Ceftazidime supplement interactions are the most serious?
None of the Ceftazidime supplement interactions on file are currently rated major. The most significant are the 36 moderate-rated ones — combinations that may need monitoring, a dose adjustment, or separated timing. Still worth a quick look through the ranked list for anything you take daily. Jump to the ranked list.
Can I take vitamins or supplements while on Ceftazidime?
That depends entirely on which supplement. The honest answer for Ceftazidime is in the ranked list above — and if what you take is a combination product with a dozen ingredients, don't check them one by one: photograph the label with our scanner and we'll check the whole thing at once. Try the label scanner or the interaction checker.
Do brands like Ceftazidime have the same supplement interactions as Ceftazidime?
Yes — Ceftazidime, Fortaz, Tazidime, Ceptaz, Tazicef all contain Ceftazidime, so everything on this page applies to them equally. Interactions belong to the active drug, never to the brand on the box; the same is true of generics.
Where do these interaction ratings come from?
Every rating comes from the Natural Medicines database — the same evidence-graded reference pharmacists and hospitals use — and each interaction carries three separate grades: severity (how bad it can be), likelihood (how well it's documented in studies and case reports), and an evidence level. Our pharmacists review the content; we never let an AI decide an interaction. See how to read the ratings and our editorial policy.
Does Ceftazidime deplete any vitamins or nutrients?
It might — Ceftazidime has 35 reported nutrient-depletion associations in the research literature, which is a different question from interactions: instead of a supplement changing the drug, the drug may lower a nutrient over time. See the Ceftazidime nutrient depletion report for the specifics and what to discuss with your pharmacist.
What about Ceftazidime and my other medications?
This page covers Ceftazidime against supplements and herbal ingredients. Checking Ceftazidime against your other prescription or OTC medications is a different tool — our drug interaction checker covers that side. Head to the drug–drug interaction checker, or read the full Ceftazidime Injection drug information.
