Adverse Reactions Cardiovascular: Facial flushing, headache, sweating, palpitations, chest pain, hypotension Respiratory: Shortness of breath, chest pressure, hyperventilation Central Nervous System: Lightheadedness, dizziness, tingling, numbness, apprehension, blurred vision, burning sensation, heaviness in arms, neck, and back Gastrointestinal: Nausea, metallic taste, tightness in throat, pressure in groin Precautions Adenosine will not convert atrial fib, atrial flutter, or VT to NSR. May be rarely associated with VF. The effects of adenosine are antagonized by methylxanthines such as caffeine and theophylline. In their presence, larger doses may be required or adenosine may not be effective. At the time of conversion to a sinus rhythm, a variety of new rhythms may occur. Generally these last a short period and are normally corrected on their own with no intervention.

Considerations Adults: Flush with 20mL NS after each dose Pediatrics: Flush with 5mL NS after each dose IV at antecubital site is important.
