What Tomudex™ is used for
Tomudex™ belongs to a group of medicines called cytotoxic agents. These agents are used for the treatment of cancer.

This medicine blocks the formation of these chemicals.

Your doctor will have explained why you are being treated with Tomudex™ and told you what dose you will be given.

The exact dose of Tomudex™ you are given will be decided by your doctor. It will vary depending on your physical size and how you react to the treatment.

The dose you are given may vary depending on your response to treatment.
