Interaction report

Phenpromethamine 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 Phenpromethamine 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.

About Phenpromethamine

What is Phenpromethamine?

  • Nasal decongestion (historical)
  • Stimulant effects (misuse)
  • Pre-workout 'energy' (illegally added to some products)

Phenpromethamine is a synthetic stimulant drug, not a herb or legitimate dietary supplement. It has been found illegally added to some sports and weight-loss supplements, and it is not approved for use in the United States. You should avoid any product that lists it as an ingredient and talk to a pharmacist or doctor.

Not applicable; phenpromethamine is a synthetic chemical, not a plant part · Historically found as a nasal inhaler; not a legitimate dietary supplement ingredient

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

Phenpromethamine: dosing

There is no established or recommended dose of phenpromethamine for supplement use. It is not an approved supplement ingredient, and any amount found in products is unregulated and potentially unsafe.Because the amount in spiked products is unknown and uncontrolled, no dose can be considered safe. The best advice is to avoid products that contain it entirely.

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.
