Adenosine
About
Adenosine belongs to a class of antiarrhythmic medications primarily used to treat a condition called paroxysmal supraventricular tachycardia (including a condition called Wolff-Parkinson-White syndrome). This condition is a form of abnormal cardiac rhythm or arrhythmia. It happens when the upper chamber of the heart produces a short circuit beat. As a result, the pulse is regular yet fast, starting and stopping suddenly. Besides, Adenosine is used as an aid to doctors to understand how your heart is working.
Adenosine contains adenosine, which works by slowing down the electrical impulses which control the heart rhythm. This allows the heart rhythm to return to normal.
Adenosine is only given in hospitals. It is provided to you as an injection by an experienced healthcare professional. Adenosine may cause side effects such as chest pain or pressure on the chest, feeling dizzy or light-headed, feeling sick (nausea), headache, unusual skin sensations, uneven heartbeat, and nervousness. Most of these side effects of Adenosine do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, reach out to your doctor.
Before prescribing the Adenosine, let your doctor know about all your medical conditions, allergic reactions, and all medications you are using. And also, inform your doctor if you are pregnant or planning pregnancy so that your doctor will weigh the benefits and potential risks before prescribing Adenosine. Avoid driving or operating tools or machinery as Adenosine may cause dizziness or light-headedness. Do not consume alcohol while on treatment with Adenosine.
Uses of Adenosine
Medicinal Benefits
Adenosine is an antiarrhythmic medication used to address a condition known as paroxysmal supraventricular tachycardia. (Including a condition called Wolff-Parkinson-White syndrome). This is when the heart pulses too quickly. Adenosine works by slowing down the electrical impulses that regulate the heart rhythm. This enables the heart rhythm to return to normal. Aside from that, Adenosine is used to help doctors comprehend how your heart works.

In-Depth Precautions and Warning
Drug Warnings
Before taking the Adenosine, let your doctor know about all your sensitivities and all medications you are using. The presence of additional medical issues may impact the use of this medication, so inform your doctor if you have any other medical issues, especially asthma or any other lung disease or epilepsy or seizures or have recently had a heart transplant or have some other problems with your heart or heart rhythm or have severe low blood pressure.
Drug Interactions
Drug-drug interactions: Adenosine may interact with antipsychotic medication (e.g. haloperidol), and it should be used cautiously in patients receiving digoxin or digoxin and verapamil in combination.
Drug-food interactions: Limit or avoid consuming Caffeine and Nicotine foods or beverages.
Drug-disease interactions: Adenosine should be used with caution in patients with AV node dysfunction, cardiovascular dysfunction, severe low blood pressure, proarrhythmic effects (medication-induced side-effects) and bronchoconstriction (narrowing of the airways) or asthma or any other lung disease.

Safety Advice
Alcohol
cautionConsuming alcohol while on treatment with Adenosine is not advisable as it may cause serious side effects.
Pregnancy
cautionIt is not known whether Adenosine can cause foetal harm if taken during pregnancy. It should be taken if clearly needed. If you are pregnant, inform your doctor. Your doctor will weigh the benefits and potential risks before prescribing Adenosine.

Disease/Condition Glossary
Arrhythmia: Arrhythmia is a problem associated with the rate of rhythm at which the heart beats. Generally, in this condition, the heart beats too fast, too slow, or irregularly. It can lead to severe heart damage. A cardiac arrhythmia occurs when there are abnormal electrical signals in the heart. When the heart beats too fast, it is known as tachycardia; if it is too slow, it is called bradycardia. Treatment of arrhythmia includes drugs, medical procedures, implantable devices and sometimes surgery.
Supraventricular tachycardia (SVT): Supraventricular tachycardia (SVT) is a medical condition where your heart suddenly beats much faster than normal. SVT occurs when the electrical system that controls your heart rhythm is malfunctioning. This leads your heart to beat much faster suddenly. It can then slow down abruptly. A normal resting heart rate is 60 to 100 beats per minute (bpm). But with SVT, your heart rate suddenly goes above 100 bpm. This can happen when you're resting or doing exercise.
Paroxysmal supraventricular tachycardia: Paroxysmal supraventricular tachycardia (PSVT) is a form of arrhythmia or abnormal heart rhythm. It happens when a short circuit rhythm develops in the heart's upper chamber. This causes a regular but rapid heartbeat that begins and ends suddenly.
FAQs
Adenosine contains adenosine, which works by slowing down the electrical impulses which control the heart rhythm. This allows the heart rhythm to return to normal.
Adenosine is contraindicated to use in a population with severely low blood pressure. So, people with severely low blood pressure should not take Adenosine.
Adenosine may cause unusual skin sensations such as reddening (with a feeling of heat) and burning sensations. In most cases, these side effects gradually resolve over time. However, if these persist or worsen, reach out to your doctor.
