What should I discuss with my healthcare provider before taking feverfew ()?
Do not take feverfew if you have a known allergy or hypersensitivity to chamomile, ragweed, yarrow, or other plants in the Asteraceae family. Also, do not take feverfew if you develop a rash after touching the feverfew plant. You may be more likely to have a serious allergic reaction to feverfew.
Do not take feverfew without first talking to your doctor if you have a bleeding or blood clotting disorder; if you are taking a medicine to prevent blood clots; or if you are taking other medications, herbs, antioxidants, or health supplements (these may also affect blood clotting). Feverfew may affect the time it takes for your blood to clot.
Before taking feverfew, talk to your doctor, pharmacist, or health care professional if you have any other medical conditions, allergies (especially to plants), or if you take other medicines or other herbal/health supplements. Feverfew may not be recommended in some situations.
There is no information available regarding the use of feverfew by children. Do not give any herbal/health supplement to a child without first talking to the child's doctor.
How should I take feverfew ()?
The use of feverfew in cultural and traditional settings may differ from concepts accepted by current Western medicine. When considering the use of herbal supplements, consultation with a primary health care professional is advisable. Additionally, consultation with a practitioner trained in the uses of herbal/health supplements may be beneficial, and coordination of treatment among all health care providers involved may be advantageous.
If you choose to take feverfew, use it as directed on the package or as directed by your doctor, pharmacist, or other health care provider.
Standardized extracts, tinctures, and solid formulations of herbal/health supplements may provide a more reliable dose of the product.
Different formulations of feverfew are available to be used internally (orally) and externally (topically).
Do not use different formulations (e.g., tablets, topical formulations, teas, tinctures, and others) of feverfew at the same time, unless specifically directed to do so by a health care professional. Using different formulations together increases the risk of an overdose of feverfew.
Store feverfew as directed on the package. In general, feverfew should be protected from light and moisture and stored in a sealed container.
