Find out what goserelin is, how you have it and other important information about taking goserelin for prostate cancer.
How it works
Prostate cancer depends on testosterone to grow. The aim of hormone therapy for prostate cancer is to reduce or stop the body making testosterone, which slows down the growth of cancer or shrinks it.
Goserelin stops the pituitary gland releasing luteinising hormone. In men, this stops the testicles producing the male sex hormone, testosterone.
How you have goserelin
You have goserelin implant injected just under the skin of your tummy (abdomen). The drug is absorbed slowly into your body over a period of time.
When you have goserelin
You might have the injection every 4 weeks or every 12 weeks, depending on what brand you take.
You should make sure you have the injection on time. A few days won’t make a big difference but the aim is to stop you producing testosterone and the injections are made to last for either 4 or 12 weeks. If you are late having the injection you may start making testosterone again.
Tests during treatment
You have blood tests before starting treatment and during your treatment. They check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.
Contraception and preventing pregnancy
Goserelin may have a harmful effect on a baby developing in the womb. You should not father a child while you are having treatment. Discuss effective contraception with your doctor before you start your treatment if this is a possibility.
Other medicines, foods and drink
Cancer drugs can interact with some other medicines and herbal products. Tell your doctor or pharmacist about any medicines you are taking. This includes vitamins, herbal supplements and over the counter remedies.
Treatment for other conditions
Always tell other doctors, nurses, pharmacists or dentists that you’re having this treatment if you need treatment for anything else, including teeth problems.
