How to take Isuprel™

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

How much is given

Your doctor will decide what dose you will receive. The dosage will depend on your condition.

How it is given

Isuprel™ will normally be given to you as an injection under the skin, or into the vein, muscle or heart.

If you take too much (overdose)

As Isuprel™ is given to you under the supervision of your doctor, it is very unlikely that you will receive too much. However, if you experience any severe side effects after being given Isuprel™, tell your doctor immediately or go to Accident and Emergency at the nearest hospital. You may need urgent medical attention.

In case of overdose, immediately contact the Poisons Information Centre for advice (telephone 13 11 26 in Australia).

Symptoms of Isuprel™ overdose include the side effects listed below in the ‘Side Effects’ section, but are usually of a more severe nature.

While you are using Isuprel™

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Isuprel™.

Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine. It may affect other medicines used during surgery.

If you become pregnant while taking this medicine, tell your doctor immediately.

If you are about to have any blood tests, tell your doctor that you are taking this medicine. It may interfere with the results of some tests.

Things to be careful of

Be careful driving or operating machinery until you know how Isuprel™ affects you. This medicine may cause dizziness and light-headedness in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.

If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.
