Caffeine-Free Guidelines in Preparation for a Stress Test
Caffeine will interfere with the results of your stress test. It is important to follow these instructions so that your test can be performed as scheduled, without delay.
Before the test
- Avoid all products that contain caffeine for 24 hours before the test. In general, caffeine is found in coffee, tea, colas and other soft drinks, most chocolate products, as well as strawberries (these contain a small amount of caffeine), as caffeine will interfere with the results of the test. Also avoid decaffeinated or caffeine-free products for 24 hours before the test, as these product contain trace amounts of caffeine.
- Since many over-the-counter medications contain caffeine (such as diet pills, NoDoz®, Excedrin® and Anacin®), DO NOT take any over-the-counter medication that contains caffeine for 24 hours before the test. Ask your physician, pharmacist or nurse if you have questions about other medications that may contain caffeine. Do not discontinue any medication without first talking with your physician.
