Is there a generic for adenosine (Adenocard)?

The FDA approved the first generic adenosine on June 16, 2004. 21 generic applications are approved; 14 of them carry a current (not discontinued) marketing status in Drugs@FDA; that status is not evidence that the generic is on sale. Drugs@FDA also holds 2 tentative approvals: the FDA found the generic approvable, but patents or exclusivity keep it from final approval for now.

FDA's NDC Directory lists adenosine from 13 labelers under a generic (ANDA) application. A listing means the company has registered the product for sale; it does not show that every pharmacy stocks it.

Has adenosine been recalled?

The FDA's Enforcement Report lists 5 recalls naming adenosine since 2013: 1 Class I (the most serious), 4 Class II, 0 Class III; 0 still ongoing. 3 of them are by firms that FDA's NDC Directory does not list as a maker of adenosine and that hold no application for it in Drugs@FDA, such as compounding pharmacies or bulk-ingredient suppliers; the recall notice names the product recalled. A recall names products and lots, not every product of the medicine.

What does the adenosine label say about other medicines?

The adenosine label names 4 other medicines in its interaction, contraindication or warning sections. The labels of 6 other medicines name adenosine. The sentences are the labels' own; a label lists what its studies and reports found, not every interaction.

Medicine namedSectionWhat the label says
Aminophyllinedrug interactionsDrugs on Adenosine The vasoactive effects of adenosine are inhibited by adenosine receptor antagonists, (such as methylxanthines (e.g., caffeine, aminophylline, and theophylline).
Caffeinedrug interactionsDrugs on Adenosine The vasoactive effects of adenosine are inhibited by adenosine receptor antagonists, (such as methylxanthines (e.g., caffeine, aminophylline, and theophylline).
Dipyridamoledrug interactionsDRUG INTERACTIONS Methylxanthines interfere with the activity of adenosine ( 7.1 , 10) Nucleoside transport inhibitors such as dipyridamole can increase the activity of adenosine
Theophyllinedrug interactionsDrugs on Adenosine The vasoactive effects of adenosine are inhibited by adenosine receptor antagonists, (such as methylxanthines (e.g., caffeine, aminophylline, and theophylline).

What do FAERS reports show for adenosine?

The FDA Adverse Event Reporting System holds 1,600 reports that list adenosine among the medicines taken, through July 30, 2026, each a report of something that happened, not proof the medicine caused it; 142 are coded as a death and 758 as a hospital stay. Counts follow how widely a medicine is used and watched, and they are not a measure of how risky it is.
