What Are The Common Coumadin Medication Interactions?

By Adam Pick on September 3, 2007

As we’ve talked about before, Coumadin (Warfarin Sodium) is used by patients following heart valve replacement in which mechanical heart valves are selected by the patient and/ or surgeon. You can click here to learn more about Coumadin medication and its long-term use for preventing blood clots on mechanical heart valves following heart valve surgery.

Coumadin Medication Interactions

That said, this blog is also starting to answer some questions about Coumadin medication interactions with other popular drugs – including Coumadin and Prilosec and Ultram and Coumadin.

In the near future, Dr. Robert Light and I are going to be addressing some of the other contraindications of Coumadin use and pharmaceuticals.

However, I did want to briefly identify some of the more well-known Coumadin medication interactions such that we have a baseline of the other research we are about to conduct. With that said, I spent some time researching coumadin medication interactions.

Here is a quick list of the common Coumadin medication interactions I located:

  • Amiodarone
  • Cimetadine
  • Clofibrate
  • Cotrimoxazole
  • Erythromycin
  • Fluconazole
  • Isoniazid
  • Metronidazole
  • Miconazole
  • Omeprazole
  • Phenylbutazone
  • Piroxicam
  • Propafenone
  • Propanolol
  • Sulfinpyrazone
  • Acetaminophen (Tylenol®)
  • Anabolic steroids
  • Aspirin
  • Chloral Hydrate
  • Ciprofloxacin
  • Dextropropoxyphene
  • Disulriam
  • Quinidine
  • Phenytoin (Dilantin®)
  • Simvastatin
  • Tamoxifen
  • Tetracycline
  • Influenza vaccine

I hope this helps explain some of the Coumadin medication interactions. In future blogs, Dr. Robert Light and I are going to further explore this topic.

Keep on tickin!
