In brief: Caffeine
You should avoid caffeine and beta blockers, just because they interfere with the test.

You may also want to ask your Cardiologist for a letter explaining why you might have residual isotope activity in the event you are flying or crossing a border since Thallium, unlike Technetium Sestamibi 99 (the most commonly used isotope in nuclear cardiology), has a longer half life.

In brief: Caffeine
As the clinic for specific details, but in general no caffeine for 24 to 48 hours, no blood pressure medications for 24 hours, and no nitrates for 24 hours.
Some clinics will have you continue your medications up to the day of the test, so check with them.

In brief: Coffe tea chocolate
If you have a pharmacological stress test such as adenosine, Dipyridamole or lexiscan, you should avoid coffee, chocolate, tea, "brown" colas and aminophylline- containing medications for 12-24 hours before the test because they contain caffeine, an "antidote' to the test.
If you have a treadmill stress test, betablockers should be stopped with the approval of your physician.
