Feverfew Side Effects
Some side effects with feverfew, while occurring infrequently, are potentially serious and should be reported immediately to your healthcare provider. These include but are not limited to:
- Contractions of the uterus during pregnancy, which can cause miscarriage or premature labor.
- Signs of an allergic reaction, such as a rash, hives, itching, swelling of the mouth or throat, wheezing, or difficulty breathing. People who are allergic to ragweed or chrysanthemums may also be allergic to feverfew.
Unpredictable side effects are also possible due to contaminants in feverfew products. Because herbs and supplements are not as tightly regulated as prescription and non-prescription drugs, they are sometimes contaminated with other herbs, medications, or even heavy metals. In order to avoid such problems, many people choose to grow their own feverfew.
You may experience some or none of the feverfew side effects listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have side effects from a medicine that you have never tried. Therefore, make sure to let your healthcare provider know if you develop any side effects while taking feverfew or if something "just does not seem right." While it may not be a side effect of feverfew, your healthcare provider will be able to diagnose and treat the problem.
