1. What Adenosine Solution for Injection is and what it is used for

Adenosine 3mg/ml Solution for Injection (called Adenosine Solution for Injection throughout the rest of this leaflet) belongs to a group of medicines called antiarrhythmics.

Antiarrhythmics are used to treat an irregular heartbeat (arrhythmias). Adenosine Solution for Injection is used during hospital tests to help doctors or nurses determine what type of rregular heartbeat you have. It works by slowing down electrical impulses in your heart, in turn, slowing down either a fast or irregular heartbeat. In children, Adenosine Solution for Injection is used to bring your child’s heartbeat back to normal if your child has a type of heart rhythm problem called ‘paroxysmal supraventricular tachycardia’ (PSVT). You will usually be in hospital when you receive this medicine.

if you have a disorder that affects the heart’s electrical activity (Long QT syndrome); if you have very low blood pressure (severe hypotension);

if you have a type of heart failure where your heart does not pump out enough blood; if you are below 18 years of age. In children with a heart rhythm problem called ‘Wolff-Parkinson-White (WPW) syndrome’, Adenosine Solution for Injection may cause some unexpected severely abnormal heart rhythm.

Tell your doctor or nurse if any of the following apply to you:

if you have recently had a heart attack, heart failure, or you have had a heart transplant within the last year; if you have a low blood volume level that has not been corrected by either treatment or medication;

arteries in your neck (carotid arteries) that prevents sufficient blood getting to your brain

•    if you have a known heart defect;

•    if you have an unusual heart rhythm (atrial fibrillation or flutter).

Using other medicines Make sure your doctor or nurse knows if you are taking, or have recently taken, any of the medicines listed here:

   Dipyridamole (used to thin the blood); taking dipyridamole at the same time as Adenosine Solution for Injection will increase the effect of adenosine on the body. Your doctor or nurse may decide not to give you Adenosine Solution for Injection, may tell you to stop taking dipyridamole 24 hours before you are given Adenosine Solution for Injection, or they may lower the dose.

   Aminophylline and theophylline (used to help breathing difficulties), or medicines containing Xanthines (caffeine), which are found in certain medicines used to treat headaches. Your doctor may tell you to stop taking these medicines 24 hours before you are given Adenosine Solution for Injection.

•    Medicines that affect the rate at which your heart conducts electrical impulses such as calcium channel blockers e.g. diltiazem and amlodipine, beta-adrenergic blocking agents e.g. propranolol and metoprolol and centrally acting agents e.g. clonidine and guanfacine.

Please also tell your doctor or nurse if you are taking, or have recently taken, any other medicines, including medicines obtained without a prescription.
