Before you take Androcur
Your doctor may ask you to sign a witnessed agreement to treatment before prescribing Androcur 50mg. You may also have a test to check the number and function of your sperm before you start treatment as Androcur 50mg can affect this. The overall number of sperm you produce will be reduced and more sperm than usual will be abnormal in shape.

Liver tumours may lead to bleeding in the abdomen, which can be life-threatening. If you have any new stomach discomfort or pain that does not go away quickly, you must tell your doctor straightaway
- blood clots have been reported in patients taking this medicine which may also be linked to the reason you are receiving Androcur. Tell your doctor if any of the following apply to you, as you may be at an increased risk of getting a blood clot. If you have:
