New research shows strong interference between certain drugs and herbal remedies.
The potential for prescription drugs to interact with herbal?supplements?is real, and withholding information about what?supplements?you take could pose potentially harmful effects.
An example of this can be seen with St. John?s wart ?- a natural remedy known for treating mood disorders. Many people are weary of taking antidepressants and choose instead to use the herbal supplement since it is strong enough to relieve mild to moderate depression. But new research shows it is also the remedy most likely to interact with?pharmaceutical?drugs.
A new report found that St. John?s wart is known to interfere with 147 different medications ? from cholesterol lowering statins to the blood thinner warfarin ? after reviewing 85 studies published in the?International Journal of Clinical Practice.
Magnesium was also found to have a high number of interactions with drugs at 102, along with calcium at 75, iron at 71 and ginkgo biloba at 51.
These interactions can either amplify or reduce the effect of certain prescription drugs, and the study identified 17 per cent could pose a major health risk such as a hypertensive crisis, excessive bleeding or a coma.
Study author Simon Pickard?noted that drug interactions with herbal remedies are tremendously?under-reported, generally because they are rarely harmful enough to require a trip to the doctor. The majority of interactions are small and can be avoided by simply making your pharmacist aware of any?supplements?you are taking when picking up a prescription, and following directions.
Less than a third of patients inform their health care provider when they are taking?supplements, which leaves room for potentially harmful interactions to happen.
For pharmaceutical drugs, warfarin had the highest number of reported interactions with?supplements. Incidents with insulin, Aspirin,?digoxin and?ticlopidine were also heavily reported.
?We were able to hone in on those disease states where we know the most about interactions and contraindications. We should be more aware with patients that have these conditions that they will potentially encounter problems if they are using [certain] herbs or dietary supplements,? Pickard wrote in the study.
In recent years, herbal remedies have become an increasingly popular choice for those looking to keep their bodies free of chemicals. ?Survey after survey shows that large proportions of the population are trying ?natural? remedies for illness-prevention, all sorts of ailments, diseases or for states of reduced well-being. Most experts therefore agree that the potential for such interactions is substantial,???Professor Edzard Ernst, Emeritus Professor at the University of Exeter wrote in an editorial on the review.
