Prescription Required Why?
Adenosine is the active ingredient in Adenosine. It is a nucleoside that plays a role in biochemical processes, such as energy transfer and signal transduction. In medicine, it is used as an antiarrhythmic agent to treat certain types of irregular heartbeats.
Adenosine is used to treat paroxysmal supraventricular tachycardia (PSVT), a condition characterized by a rapid heart rate originating above the heart's ventricles. It is also used during a cardiac stress test to help identify coronary artery disease.
PSVT: The initial dose is typically 6 mg given as a rapid intravenous (IV) bolus over 1 to 2 seconds. If the first dose does not result in normalization of the heart rate within 1 to 2 minutes, a 12 mg dose may be given. A third dose of 12 mg may be administered if necessary.
Cardiac Stress Test: The dosage for this use is typically 140 mcg/kg/min administered as an IV infusion over 6 minutes.
Dosage may vary based on the condition being treated and the patient's response. Always follow the dosage prescribed by your healthcare provider.
Administration: Adenosine is administered by a healthcare professional as a rapid IV injection or as an infusion.
Monitoring: Heart rate and rhythm should be continuously monitored during administration.
Cautions
Allergic Reactions: Inform your doctor if you are allergic to adenosine or any other medications.
Medical History: Disclose your full medical history, especially if you have asthma, certain types of heart problems (such as heart block, sick sinus syndrome), or a history of seizures.
Pregnancy and Breastfeeding: Use only if clearly needed during pregnancy. Discuss risks and benefits with your doctor. It is unknown if this drug passes into breast milk.
Interactions: Adenosine can interact with certain medications, including theophylline, caffeine, and certain heart medications. Inform your doctor of all medications you are taking.
Missed Dose: This medication is given in a clinical setting, so missed doses are not common. If a dose is missed, it will be administered as soon as possible.
Storage: Adenosine should be stored at room temperature away from light and moisture.
