Dulse 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 Dulse 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.

Dulse safety at a glance

Dulse overall Use caution Generally safe as a food, but supplements may contain high iodine and potassium and should be used cautiously.
Pregnancy Use caution Food amounts are likely fine, but avoid concentrated supplements due to unpredictable iodine levels and limited safety data.
Breastfeeding Use caution Limited data; excess iodine can pass into breast milk, so avoid supplement doses and check with your doctor.

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

How we checked

Why No Interaction Is Listed for Avibactam Sodium, Ceftazidime

Interactions in our licensed database are recorded against drug classes, not just single drug names. Avibactam Sodium, Ceftazidime is filed under 4 classifications — including organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates, antibiotic drugs. Dulse has documented interactions with 7 drug classes — the most serious being amiodarine (cordarone) (moderate), antithyroid drugs (moderate) and digoxin (lanoxin) (moderate) — and none of Avibactam Sodium, Ceftazidime’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.

About Dulse

What is Dulse?

Dulse
  • Nutritional supplement (iodine, minerals)
  • Source of plant protein
  • General wellness
  • Anti-inflammatory support
  • Thyroid/iodine support

Dulse is a red seaweed eaten as a food in many coastal cultures and is a natural source of iodine, potassium, protein, and antioxidant compounds. As a food it is generally considered safe for most people, but concentrated supplements can deliver large amounts of iodine and potassium, so use caution. Talk to your pharmacist or doctor before using it medicinally, especially if you have thyroid or kidney problems.

Palmaria palmata · Palmariaceae · Whole edible thallus (the leafy seaweed fronds) · Dried flakes, whole dried leaf, powder, capsules, and as a food ingredient

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

Dulse: dosing

There is no established standardized medicinal dose for dulse. As a food it is eaten in small amounts as flakes, snacks, or a recipe ingredient.If you use a dulse supplement, follow the directions on the product label and do not exceed the recommended amount.

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.
