Leuprorelin (Prostap, Lutrate)
This page tells you about the hormone drug leuprorelin and its possible side effects. There is information about
Leuprorelin is pronounced loop-row-rel-in. It is also called Prostap or Lutrate. It is a type of hormone therapy treatment for prostate cancer.
Prostate cancer depends on testosterone to grow. Leuprorelin lowers the level of testosterone made by the testicles. So leuprorelin can shrink the cancer or slow its growth.
You have leuprorelin as
- An injection into a muscle in your leg or buttocks or
- An injection just under the skin (subcutaneously) into fatty tissue in your abdomen, thigh or upper arm
The injection is called a depot injection, which means that you slowly absorb the drug into your body over a period of time. You have the injection every month or every 3 months.
You can read about having injections into a muscle or under the skin.
It is important to make sure you have the injection on time. If you are more than a few days late having the injection your body may start making testosterone again.
You have blood tests before starting treatment and regularly during your treatment. The tests check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.
We've listed the side effects associated with leuprorelin. You can use the links to find out more about each side effect. Where there is no link, please go to our information about cancer drug side effects or use the search box at the top of the page.
You may have a few side effects. They may be mild or more severe. A side effect may get better or worse through your course of treatment. Or more side effects may develop as the course goes on. This depends on
- How many times you've had the drug before

- The amount of the drug you have (the dose)
The side effects may be different if you are having leuprorelin with other medicines.
Tell your doctor or nurse straight away if any of the side effects get severe.
Men having leuprorelin for prostate cancer may have an increase in symptoms called tumour flare for the first few weeks of the treatment. Your doctor may give you another type of hormone drug to start with, to try to prevent this. The symptoms of tumour flare include

Tell your doctor or nurse if you have any of these effects.
