Drug & supplement interaction

Witch Hazel + Avibactam Sodium, Ceftazidime

Avibactam Sodium, Ceftazidime brand name: Avycaz.

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 Witch Hazel and Avibactam Sodium, Ceftazidime 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.

Interaction report

Witch Hazel and Avibactam Sodium, Ceftazidime

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 Avibactam Sodium, Ceftazidime and Witch Hazel 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 Witch Hazel at all — not against Avibactam Sodium, Ceftazidime, 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 Witch Hazel and Avibactam Sodium, Ceftazidime 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.

  • Liver problems Worth acting on Additional detail

    Witch Hazel

    “Topically, witch hazel is generally well tolerated. Orally, witch hazel seems to be well tolerated at appropriate doses, but high doses may be associated with more adverse effects due to the tannin content in witch hazel.

    Most Common Adverse Effects:

    Topically: Contact dermatitis.

    Serious Adverse Effects (Rare):

    Orally: Kidney and liver damage when preparations containing at least 10% tannins are used in high doses.”

About Witch Hazel

What is Witch Hazel?

  • Skin irritation and inflammation
  • Hemorrhoids
  • Minor cuts and bruises
  • Oily or acne-prone skin
  • Itching and minor swelling
  • Soothing after shaving or sun exposure

Witch hazel is a plant-based astringent used mostly on the skin for minor irritation, hemorrhoids, and oily skin. It is generally well tolerated as a topical product for short-term use, but evidence for most uses is limited, and it should not be swallowed. Check with your pharmacist or doctor before using it, especially during pregnancy or breastfeeding.

Hamamelis virginiana · Hamamelidaceae · Bark, leaves, and twigs · Liquid astringent (distilled water), gels, ointments, creams, wipes/pads, suppositories, soaps

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

Witch Hazel: dosing

There is no official standardized dose for witch hazel. The right amount depends on the product and the form, such as a liquid, gel, pad, or ointment.The safest approach is to follow the directions on the product label and use it only on the skin as directed. For hemorrhoid pads or creams, follow the package instructions. Do not take witch hazel by mouth unless a healthcare professional specifically advises it.

About Ceftazidime and Avibactam Injection

What Is Ceftazidime and Avibactam Injection Used For?

Brand name: Avycaz

Avycaz (ceftazidime and avibactam) is used to treat three types of serious bacterial infections in adults and children at least 31 weeks gestational age: complicated intra-abdominal infections (cIAI), complicated urinary tract infections (cUTI) including pyelonephritis (a kidney infection), and hospital-acquired bacterial pneumonia or ventilator-associated bacterial pneumonia (HABP/VABP). All three of these infections must be caused by specific susceptible gram-negative bacteria for Avycaz to be effective.

When treating complicated intra-abdominal infections, Avycaz must be used together with metronidazole, another antibiotic. Avycaz is only meant for infections proven or strongly suspected to be caused by bacteria that it can actually fight — using it otherwise can lead to antibiotic resistance.
