‘A phototoxic reaction occurred in a patient

pretreatment with St. John’s wort decreased
the area under the curve for amitriptyline (and
its active metabolite nortriptyline), digoxin,
indinavir, midazolam, phenprocoumon, and the
active metabolite of simvastatin (simvastatin

(sometimes with transplant rejection),
tacrolimus, and theophylline; with increased
oral clearance of nevirapine; with

@ suggestions (IT)
™ Medical and pharmaceutical communities had
been slow to respond to this important issue
= Government, industry and medical societies
