Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about Adenosine Mylan.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. Your doctor has weighed the risks of you taking adenosine against the benefits expected for you.

If you have any concerns about taking this medicine, talk to your doctor or pharmacist.

Keep this leaflet with your medicine. You may need to read it again.

What this medicine is used for

Adenosine Mylan is used to treat a condition called paroxysmal supraventricular tachycardia (including a condition called Wolff-Parkinson-White syndrome). This is when the heart beats too rapidly. If left untreated, this condition can be life threatening.

Adenosine can also be used as an aid to doctors to understand how your heart is working.

It works by slowing down the electrical impulses that control heart rhythm. This allows the heart rhythm to return to normal.

Adenosine is only given in hospitals. It is given to you as an injection. The effect of this medicine only lasts for a couple of minutes.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another use.

There is no evidence this medicine is addictive.

This medicine is available only with a doctor's prescription.

How it is given

Adenosine Mylan will be given to you in a hospital by a trained healthcare professional.

How much to be given

Your doctor will decide what dose of Adenosine Mylan you will receive. This depends on your condition. Usually you will only need one or several doses a few minutes apart.

How it is given

Adenosine Mylan is given by injection either directly into a vein or via an intravenous (I.V.) line.

If you are given too much (overdose)

As this medicine is given to you under the supervision of your doctor, it is very unlikely that you will be given too much.

However, tell your doctor or nurse immediately if you think you have received too much of this medicine.

Side effects

Tell your doctor or nurse as soon as possible if you do not feel well during or after treatment with adenosine.

This medicine helps most people who are treated with it, but it may have unwanted side effects in some people.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

Ask your doctor to answer any questions you may have.

Tell your doctor if you notice any of the following and they worry you:

  • facial flushing
  • shortness of breath or urge to breathe deeply
  • a feeling of tightness across the chest
  • nausea
  • headache
  • light headedness or dizziness

These are very serious side effects. If you have them, you may have had a serious allergic reaction to adenosine. You may need urgent medical attention.
