1. What Zoladex LA is and what it is used for

Zoladex LA contains a medicine called goserelin. This belongs to a group of medicines called ‘LHRH analogues’.

Zoladex LA is used to treat prostate cancer. It works by reducing the amount of ‘testosterone’ (a hormone) that is produced by your body. Zoladex LA is a long-acting form of Zoladex and it is given every 12 weeks.

2. What you need to know before you use Zoladex LA

Do not use Zoladex LA:

  • if you are allergic to goserelin or any of the other ingredients of this medicine (listed in section 6).
  • if you are a woman.

Do not have Zoladex LA if any of the above apply to you. If you are not sure, talk to your doctor, pharmacist or nurse before having Zoladex LA.

  • if you have diabetes.
  • if you have high blood pressure.
  • if you have any condition that affects the strength of your bones, especially if you are a heavy drinker, a smoker, have a family history of osteoporosis (a condition that affects the strength of your bones) or take anticonvulsants (medicines for epilepsy or fits) or corticosteroids (steroids).
  • if you have any heart or blood vessel conditions, including heart rhythm problems (arrhythmia), or are being treated with medicines for these conditions. The risk of heart rhythm problems may be increased when using Zoladex LA.
