Dosing

Adults (18 years and older)

Studies have reported safety and good tolerability of commercially available butterbur products (which are free of potentially carcinogenic pyrrolizidine alkaloid constituents), when used orally in recommended doses for up to 12- 16 weeks.

For allergic rhinitis, 50 milligrams of standardized butterbur (Petadolex®, standardized to contain 7.5 milligrams of petasin and isopetasin per 50- milligrams tablet) has been used twice daily. A large study used one tablet of carbon dioxide extract standardized to 8.0 milligrams of total petasin per tablet (Tesalin®), taken four times daily, while a smaller study reported that 2 standardized tablets taken three times daily was effective.

Dosing for asthma is undefined due to a lack of evidence. However, 50 milligrams of standardized butterbur (Petaforce®), administered in two divided daily doses, in patients maintained on inhaled corticosteroids has been used. Petadolex® 150 milligrams daily in three divided daily doses for 2- 4 months has also been studied.

For migraine prophylaxis, 50- 75 milligrams Petadolex® twice daily for up to four months has been studied. One study suggested that the 75- milligram dose but not the 50- milligram dose is effective.

Children (younger than 18 years)

For asthma, 50- 150 milligrams daily (depending on age) of a pyrrolizidine- free butterbur rhizome extract standardized to 7.5 milligrams of petasin and isopetasin per 50- milligram tablet (Petadolex®) may be effective. However, due to a lack of safety and efficacy data, butterbur cannot be recommended for this or any other use in children at this time.
