Generic Name: adenosine (a-DEN-oh-seen)
Brand Name: Examples include Adenocard and Adenoscan
Adenosine is used for:
Treating certain types of irregular heartbeat. Certain brands of adenosine are used during a stress test of the heart. It may also be used for other conditions as determined by your doctor.
Adenosine is an antiarrhythmic and a nucleoside. It works to treat irregular heartbeat by slowing the electrical conduction in the heart, slowing heart rate, or normalizing heart rhythm. It helps during a stress test of the heart by improving blood flow to the heart.
Do NOT use adenosine if:
- you are allergic to any ingredient in adenosine
- you have second- or third-degree heart block and do not have an artificial pacemaker
- you have sinus node disease (eg, sick sinus syndrome) and do not have an artificial pacemaker
- you have certain breathing problems (eg, asthma)
Contact your doctor or health care provider right away if any of these apply to you.
