How you prepare

By Mayo Clinic Staff

You may be asked not to eat, drink or smoke for two hours before a nuclear stress test. Ask your doctor if you should avoid caffeine or certain medications the day before the test, because they can interfere with certain stress tests. Otherwise, you can take your medications as usual.

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.

Wear or bring comfortable clothes and walking shoes.
