Adenosine is a chemical found in mammals which is also used as a medication. As a medication it is used to treat or diagnosis certain forms of supraventricular tachycardia that do not improve with vagal maneuvers. It is generally used by rapid injection into a vein. Onset of action is within 40 seconds and effects last for less than 2 minutes.

Common side effects include chest pain, feeling faint, shortness of breath, and tingling of the skin. Serious side effects include a worsening dysrhythmia and low blood pressure. While it may be used during pregnancy, safety is not entirely clear. Adenosine is one of four nucleoside building blocks to RNA. It works by decreasing the frequency by which electrical signals can go through the AV node of the heart.

Adenosine was approved for medical use in the United States in 1989. It; however, has been studied within living systems since the 1920s. Adenosine is avaliable as a generic medication. It is not expensive. In the United Kingdom in 2020 a 6 mg dose costs the NHS about a pound.
