Interactions with Herbs
Yohimbine
The active ingredients in yohimbine can block the actions of brimonidine in certain human
tissues,1 thus reducing the drug’s beneficial effects. Adequate human studies
involving the eye are lacking, and until more information is available, yohimbine should be
avoided in people using brimonidine.
Interactions with Foods and Other Compounds
Alcohol
Although human studies are lacking, preliminary studies suggest alcohol may enhance the
effects of brimonidine.2 Until more is known, individuals using brimonidine should
avoid alcoholic beverages.
