Why have I been prescribed Decapeptyl?
- Decapeptyl (triptorelin) is used in men for the treatment of a disease of the prostate, in women for the treatment of endometriosis and infertility, and in children for the treatment of precocious puberty.
How does it work?
- It lowers the levels of the sex hormones in the body and thus suppresses testicular and ovarian functions.
When and how do I take it?
The doctor will inject the contents of one vial, made up in the solvent provided. The injection will usually be given in your buttock. It is not necessary to adjust the dose if you are elderly, or if your liver or kidneys do not work so well. In women, Decapeptyl must be started in the first five days of menstrual cycle. Please confirm this with your doctor. During the first month of treatment a non-hormonal contraceptive is necessary.
What’s the dose?
There are two different products with different doses.
For Decapeptyl 3 Monthly: you will be given one injection every three months. Your doctor will decide for how long you need treatment. Men will be given their first injection in hospital. Women receiving treatment will not be given more than two injections (6 months treatment).
Children will receive injection once every three months and the treatment will be stopped when you are about 12 if you are a girl and at about 13-14 if you are a boy.
For Decapeptyl SR patients will receive one injection every month. In women receiving Decapeptyl for infertility you will get one injection at the beginning of your menstrual cycle. The other hormones (gonadotrophins) will usually be given approximately two weeks later.
Could it interact with other tablets?
- Hyperprolactinemic drugs should not be taken at the same time as Decapeptyl eg Parlodel and Dostinex.
- Herbal supplements should be used with caution and only after informing your doctor first.
