What is the initial dosage of Adenosine for adults?

The initial dosage of Adenosine for adults is 6 mg. Adenosine is commonly used in the treatment of certain types of paroxysmal supraventricular tachycardia (SVT). When administering Adenosine, the first dose is typically 6 mg, which can be given rapidly as an intravenous bolus. If the first dose does not convert the arrhythmia, a second dose of 12 mg may be given if needed. This dosing strategy is based on the pharmacological action of Adenosine, which helps to restore normal heart rhythm by decreasing heart rate through its effects on the AV node. The administration should be followed with a flush of saline to ensure that the medication reaches the heart quickly, thereby enhancing its effectiveness in converting the tachyarrhythmia.
