Heart drugs and supplements a risky mix

Herbal and dietary supplements are found in the aisles of supermarkets and health-food stores rather than behind a pharmacy counter, and they can be  dangerous when mixed with the wrong drug.

A new survey suggests that a majority of heart patients taking the popular blood-thinning drug warfarin are risking potentially dangerous complications by combining it with supplements such as fish oil, glucosamine and chondroitin, coenzyme Q10, and multivitamins.

The survey, which included 100 heart patients in Utah, found that more than two-thirds were taking dietary supplements in addition to their prescribed blood thinner, in most cases unbeknownst to their doctor. Nearly half of the patients didn't view supplements as drugs.

"More and more patients are self-medicating with these supplements," says Jennifer Strohecker, a clinical pharmacist at Intermountain Medical Center, in Salt Lake City. "Many of us will Google something and then go out and try it, and our doctor would never know."

In a previous study, Strohecker and her colleagues found that nine of the 10 most commonly sold supplements had the potential to conflict with warfarin. The offenders included St. John's wort, melatonin, glucosamine and chondroitin, and fish oil.

"Even your multivitamin can interact with warfarin," says Strohecker, who presented her research Sunday at the American Heart Association's annual Scientific Sessions meeting in Chicago, Illinois.

Some supplements have the ability to either enhance or negate warfarin's effects, which could potentially trigger one of two dangerous complications: severe bleeding or a blood clot.

"People think that a supplement is always natural and safe," Strohecker says. "They don't realize that the body sees it as a chemical." (As she likes to tell her patients in an effort to set them straight, warfarin itself was originally derived from a plant called sweet clover.)

Perhaps the most alarming finding of the survey was the apparent communication gap between doctors and patients. Less than one-third of the survey respondents said that their doctors had specifically asked them about supplement use, though nearly all said they would discuss it if asked. (Patients who don't view supplements as drugs tend not to list them on standard doctor's office paperwork, Strohecker says.)

In addition to recommending that doctors ask patients about supplement use, Strohecker suggests that patients who choose to take supplements do so consistently.

"I also fully believe that there should be some cautionary statements or some labeling changes on the supplements themselves," Strohecker says. "It's a communication thing."

The Scientific Sessions meeting highlights the latest heart-related research and treatment advances. Unlike studies published in medical journals, the research presented at the meeting has not been vetted by independent experts in the field.
