Adenosine is a nucleoside, a chemical formed from nucleic acid, present throughout the body. An adenosine injection is an antiarrhythmic agent, which is a drug that normalizes heart rhythm. It is used to treat a certain type of fast heartbeat. The mechanism of action is to slow down electrical conduction in the heart, which causes the heart to beat more slowly. Although it's usually administered in a physician's office or clinic, the patient can be taught how to use adenosine medication in the home as well.

Those who have been prescribed this medicine for home use will be carefully instructed in how to use it. Adenosine shouldn't be used if particles or cloudiness is noted in the solution, or if the vial is damaged in any way. Patients should never use needles and syringes more than once, and should be taught the proper method for disposing of them. If they forget a dose, they need to notify their doctor right away. Additionally, doctors will want to monitor the effectiveness of the drug, so they should be notified if a very fast heart rate comes back

An adenosine injection should not be administered to patients with certain medical disorders and it can cause interactions with some drugs. The doctor should be made aware of all of the patient's prescription medications, over-the-counter medicine, and herbal or nutritional supplements. Those who have lung diseases, such as emphysema or bronchitis, should make these conditions known, as should women who are pregnant or lac.tating. Physicians should also be apprised of all known drug and food allergies

Frequent side effects of an adenosine injection are chest pressure, dizziness, and flushing of the face. Headaches, lightheadedness, and nausea are also commonly experienced. Patients should go to the emergency room if they have any allergy symptoms, such as rash, difficulty breathing, or swelling of the mouth or face. Other symptoms that require very quick medical intervention include fast or slow heartbeat, chest pain, or seizures. Shortness of breath and wheezing are also symptoms that require prompt medical treatment.

Since an adenosine injection can produce dizziness, patients are advised to not use alcohol. Large quantities of caffeine-containing food and drinks should be avoided. Patients should abstain from driving unless they are tolerating the medication very well. They should discuss any concerns about the medication with their druggist or doctor. If their condition doesn't improve or if it worsens, their physician should be notified as well.
