Hirudotherapy + 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 Hirudotherapy 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

Hirudotherapy 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 Hirudotherapy in our sources. This does not guarantee that the combination is completely free of risk — research on Hirudotherapy alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Hirudotherapy 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.

Hirudotherapy is a treatment rather than something you take. Tell whoever provides it which medicines you use, and ask your prescriber whether it is appropriate for your health and treatment. 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.

Hirudotherapy safety at a glance

Hirudotherapy overall Use caution Should only be performed by trained practitioners using medical-grade leeches due to infection and bleeding risks.
Pregnancy Avoid Not enough safety data; the bleeding and infection risks make it best avoided in pregnancy.
Breastfeeding Avoid Safety during breastfeeding is unknown, so it is best avoided unless a doctor advises otherwise.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

No Interaction Found — But Data Suggests Hirudotherapy 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 having Hirudotherapy while taking the medicine can make those effects more likely to turn up, and harder to pin on one or the other if they do. 3 of them are worth acting on rather than waiting out — marked below.

  • Anemia / Bleeding or bruising Worth acting on Additional detail

    Hirudotherapy

    “Topically, hirudotherapy can cause prolonged bleeding and anemia. In a case report, a young adult male presented with neck bleeding after self-applying leeches for acne. Bleeding was controlled by suturing. A case series in critically ill pediatric patients describes bleeding that led to hirudotherapy discontinuation in 5 of 7 cases, and 4 of the patients expired secondary to multiorgan failure.”

    Hirudotherapy

    “Topically, hirudotherapy can cause itching, pain, vesicle formation, and skin redness at the application site. Less often, it can cause necrotic ulcers, keloid formation, allergic or irritant contact dermatitis, and skin infections. Use of leeches can sometimes cause infections with Aeromonas hydrophila, which is found in the leech gut, and also with parasites.”

About Hirudotherapy

What is Hirudotherapy?

  • Reconstructive and plastic surgery (relieving blood congestion in reattached tissue)
  • Osteoarthritis and joint pain
  • Circulation problems
  • Varicose veins
  • Traditional treatment for various inflammatory conditions

Hirudotherapy is the medical use of living leeches placed on the skin to draw blood and release saliva compounds that thin blood and ease congestion. It has a real, accepted role in some surgical settings (such as saving reattached fingers or skin flaps), but evidence for most other uses is limited. It should only be done by trained professionals because of risks of infection and bleeding.

Hirudo medicinalis · Hirudinidae · Whole living medicinal leech (and its saliva) · Live medicinal leeches applied to the skin by a trained practitioner

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

Hirudotherapy: dosing

There is no standardized "dose" for hirudotherapy. The number of leeches, where they are placed, and how long treatment continues are decided by the treating clinician based on the medical situation, such as how much blood is congested in a tissue flap.This is a medical procedure, not a supplement you take at home.

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.
