MYLERAN is used to treat certain blood disorders.

It works by reducing the amount of certain types of blood cells in your body.

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

How to take it

How much to take

Take MYLERAN tablets exactly as directed by your doctor. Your doctor will decide what dose and for how long you will be taking MYLERAN. This depends on factors such as your weight, any pre-existing conditions and your response to the treatment. Your doctor may change the dose and frequency of your medicine as your condition changes.

Your doctor may order regular blood tests while you are taking MYLERAN in order to monitor your blood cell count and to change your dose if necessary.

How to take it

Swallow each tablet whole with water.

Do not break, crush or chew the tablets.

If you forget to take it

Tell your doctor if you forget to take a dose.

Do not take a double dose to make up for the dose that you missed.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 131126) for advice, or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much MYLERAN. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Things you must do

Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed. Otherwise your doctor may think that it was not effective and change your treatment unnecessarily.
