What medications should not be taken before a nuclear stress test?
Medications with caffeine: Do not take any over-the-counter medication that contains caffeine (such as Excedrin®, Anacin®, diet pills and NoDoz®) for 24 hours before the test.
Can you take aspirin before a stress test?
12 hours before your test: You cannot have any products containing caffeine; this includes coffee, tea, decaffeinated products, soda and/or chocolate. Do not take any aspirin products containing caffeine, or any medications containing theophylline or persantine.

Can LEXISCAN cause AFIB?
5.3 Atrial Fibrillation/Atrial Flutter New-onset or recurrent atrial fibrillation with rapid ventricular response and atrial flutter have been reported following LEXISCAN injection [see Adverse Reactions (6.2)].
Can you drive yourself home after a nuclear stress test?
You may not drive yourself home after your test. Before coming for your test, arrange for someone to take you home afterwards.
How does aspirin affect an EKG?
Exercise-induced ischemic ECG changes were not altered by aspirin. Thus, aspirin significantly reduces platelet aggregability in patients with angina pectoris but does not improve exercise tolerance, change pain threshold, or alter ischemic ECG abnormalities.
How does caffeine affect a lexiscan?
most common (incidence ≥ 5%) adverse reactions to LEXISCAN are dyspnea, headache, flushing, chest discomfort, dizziness, angina pectoris, chest pain, and nausea (6). Methylxanthines, e.g., caffeine, aminophylline and theophylline, interfere with the activity of LEXISCAN (7.1, 12.2).
What does lexiscan feel like?

Is lexiscan hard on kidneys?
Low blood pressure and heart arrest (cardiac arrest) can injure the kidneys, but the drugs or nuclear scans should not have any direct effect on the kidneys.
How long does lexiscan stay in your body?
How long does the injection stay in my system? The nuclear imaging agent is out of your system within 60 hours, but it is always decaying so it becomes minimal in a relatively short period of time.
Are there any contraindications to taking Lexiscan?
Contraindications. Do not administer Lexiscan to patients with second- or third-degree AV block or sinus node dysfunction unless these patients have a functioning artificial pacemaker. Warnings and Precautions. Myocardial Ischemia
Can a Lexiscan injection be used for AV blockage?
Lexiscan ® (regadenoson) injection is a pharmacologic stress agent indicated for radionuclide myocardial perfusion imaging (MPI) in patients unable to undergo adequate exercise stress. Do not administer Lexiscan to patients with second- or third-degree AV block or sinus node dysfunction unless these patients have a functioning artificial pacemaker.
When to take Lexiscan for cardiac stress test?
Lexiscan® (regadenoson) injection is a prescription medicine that goes into your blood by an IV (intravenous) line. It increases blood flow through the arteries of the heart during a cardiac nuclear stress test. Lexiscan is used when a patient cannot exercise adequately for a stress test. Do’s and don’ts, including “no caffeine!”
Can a Lexiscan injection cause a heart attack?
Do not administer Lexiscan to patients with second- or third-degree AV block or sinus node dysfunction unless these patients have a functioning artificial pacemaker. Fatal and nonfatal myocardial infarction, ventricular arrhythmias, and cardiac arrest have occurred following Lexiscan injection.
