The evidence in words
The interaction
Guarana and Caffeine — a caution interaction. It IS caffeine — don't double up.
What to do
Do not combine these casually. The interaction can matter clinically — bring it to the prescriber who manages the medication before stacking them.
About Guarana
Guarana is a seed extract very high in caffeine (plus tannins), common in energy drinks and fat-burners.
The bigger picture
Supplement–drug and supplement–supplement interactions are the reason a stack should be read as a system, not a list. This platform's interactions graph maps them; the medication side always belongs with the person who prescribes it.
