Feverfew Dosage

At this time, there are no established feverfew dosage recommendations. In clinical studies, researchers often use doses ranging from 50 to 100 mg daily for the prevention of migraines. However, there is no standard feverfew dosing that has been determined to be safe. Since the production of herbal supplements is not closely regulated, it is important to choose a trustworthy manufacturer of feverfew supplements.

 

An Introduction to Feverfew Dosage

It is important to note that unlike medications, for which the standard doses have been well established, there is less information available for determining the best dose for herbal supplements, including feverfew.
 

What Is a Reasonable Feverfew Dose?

Some information about feverfew dosing can be obtained from clinical studies and from practical experience with the supplement. Studies often use feverfew doses ranging from 50 to 100 mg once daily for migraine prevention. It is not known what the best dose for other feverfew uses may be, as these other uses have not been studied as thoroughly. It is important to realize that feverfew products can vary greatly, both in feverfew content and in the content of the active medicinal compounds in the supplement. Some feverfew products may actually contain little or no feverfew, despite what the label says.
 
Some people choose to grow their own feverfew and chew the leaves. It is not known what the best dose is for this type of use.
 

General Information on Dosing for Feverfew

Considerations for people taking feverfew include the following:
 
  • Since the manufacturing of supplements (such as feverfew) is not closely regulated, it is important to choose a trustworthy manufacturer of feverfew supplements. It is a good idea to look for the "USP" or "NF" symbol, since this means that the supplement has been tested and contains the right ingredients in the right amounts.
     
  • If you have any chronic health problems or take any prescription medications, you should check with your healthcare provider before taking feverfew.
     
  • If you are unsure about anything related to your feverfew dosage, please talk with your healthcare provider or pharmacist.
