Can herbal health products or supplements change the way prescription or OTC drugs work?

Yes. Herbal health products or supplements can affect the way the body processes drugs. When this happens, your medicine may not work the way it should. For example, St. John’s wort reduces the amount of certain drugs absorbed by the body. This may mean the drugs aren’t absorbed at high enough levels to help the conditions for which they are prescribed. This can cause serious problems.

You should be especially cautious about using herbal health products or supplements if you take a drug in one of the following categories:

* Drugs to treat depression, anxiety or other psychiatric problems
* Anti-seizure drugs
* Blood thinners
* Blood pressure medicine
* Heart medicine
* Drugs to treat diabetes
* Cancer drugs

If you take any of these drugs, talk to your doctor before taking any type of herbal product or supplement.
