What are monoamine oxidase (MAO) inhibitors? How do they interact with other drugs?


Ephedra


Effect: Dangerous Interaction




Because it contains the stimulant ephedrine, combining the herb
ephedra with monoamine oxidase (MAO) inhibitors can rapidly
produce a severe, dangerous interaction and should be avoided. In the United
States, it is illegal to sell products containing ephedra.




Scotch Broom


Effect: Dangerous Interaction


The herb scotch broom contains high levels of tyramine, so it should not be taken with MAO inhibitors.




Green Tea


Effect: Probable Dangerous Interaction


Because it contains caffeine, green tea should not be
combined with MAO inhibitors.




Ginseng


Effect: Possible Dangerous Interaction


According to one report, the combination of ginseng and
the MAO inhibitor phenelzine caused worrisome symptoms. While this may have been
caused by caffeine contamination of the ginseng, experts recommend avoiding
ginseng-MAO inhibitor combinations.




St. John’s Wort


Effect: Possible Dangerous Interaction


Current thinking suggests that St. John’s wort functions somewhat
similarly to SSRI (selective serotonin-reuptake inhibitor)
antidepressants. Because SSRIs should not be combined with MAO inhibitors, St.
John’s wort probably should not be combined with them either.




5-hydroxytryptophan (5-HTP), S-adenosylmethionine (SAMe)


Effect: Possible Dangerous Interactions


Based on one case report and on current thinking about how they work,
SAMe and 5-HTP should not be combined with MAO
inhibitors.
