Zoladex® 3.6mg helps most people with the illnesses it treats, but it may have unwanted side effects in a few people.
It can be hard to work out whether side effects are caused by Zoladex® 3.6mg or the disease that is being treated.
All medicines can have side effects. Sometimes they are serious but most of the time they are not. You may need medical treatment if you get some of the side effects.
Ask your doctor, nurse or pharmacist to answer any questions you may have. Tell your doctor if you notice any of the following and they worry you:
- skin rashes
- painful joints
- hot flushes, sweating or feeling faint
- tingling in fingers or toes
- swelling, soreness or itchiness of the breasts
- mood changes
- trouble passing urine or lower back pain
- your testicles getting smaller.
These are all mild side effects of Zoladex® 3.6mg.
Zoladex® 3.6mg lowers the amount of sex hormones in your body so your sex drive will probably be reduced. It is unlikely that you can father a child while using Zoladex® 3.6mg, unless it is for infertility treatment. Use a barrier contraceptive method as a precaution.
In men and women who have not gone through the 'change of life', Zoladex® 3.6mg is likely to reduce the amount of calcium in their bones, leading to a loss in bone mineral density. It is known that bone mineral density loss partially recovers in the next several months following cessation of therapy. However, doctors do not know if bone mineral density loss will recover completely in every person. Discuss this with your doctor or pharmacist if you are concerned.
What are the less common side effects?
If you have a tumour in your pituitary gland, Zoladex® 3.6mg may make the tumour bleed or collapse. This is very rare but causes severe headaches, sickness, loss of eyesight and unconsciousness.
Your doctor will be happy to discuss these side effects with you if you seek further information. Tell your doctor, nurse or pharmacist if you notice anything else that is making you feel unwell.
Some people may get other side effects while being treated with Zoladex® 3.6mg.
