Your doctor will give you specific instructions on how to prepare for your stress test.
Food and medications
You may be asked not to eat, drink or smoke for a period of time before a stress test. You may need to avoid caffeine the day before and the day of the test.
Ask your doctor if it's safe for you to continue taking all of your prescription and over-the-counter medications before the test, because they might interfere with certain stress tests.
If you use an inhaler for asthma or other breathing problems, bring it to the test. Make sure your doctor and the health care team member monitoring your stress test know that you use an inhaler.
Clothing and personal items
Wear or bring comfortable clothes and walking shoes. If you're having a nuclear stress test, don't apply oil, lotion or cream to your skin that day.
