Table of contents:
Zoladex (generic name: goserelin) is a medication used to treat certain types of cancer, such as prostate and breast cancer. It is used to thin the lining of the uterus and may be used as a palliative treatment to help ease symptoms such as bone pain and trouble urinating. Zoladex is a synthetic decapeptide analogue of GnRH and works by inhibiting pituitary gonadotropin secretion, resulting in decreased levels of estrogen and testosterone.
Zoladex is an injectable medication used to treat a number of medical conditions for over 25 years. It is most used to treat cancer and endocrine disorders, but it can also be used to relieve symptoms of premenstrual syndrome (PMS) and other menstrual-related issues.
Uses and Dosage
Zoladex is available in a pre-filled disposable syringe device, which is fitted with a small pellet containing goserelin acetate, the active ingredient.
Here are some general steps to follow:
- Remove the plastic safety tab and needle cover from the disposable syringe.
- Pinch the skin and use aseptic technique to prepare the injection site.
- Insert the syringe into the prepared injection site at a 30–45-degree angle and slowly depress the plunger to administer the medication.
- After injecting the medication, remove the syringe from the injection site and dispose of it properly.
- Monitor the injection site and contact a healthcare professional if there are any signs of infection or other adverse reactions.
The recommended dosage of Zoladex can depend on numerous factors such as the type of cancer being treated and the individual’s medical history. Here are some general recommended dosages based on the available information:
- For the palliative treatment of prostate cancer: Zoladex 3.6mg implant injected subcutaneously (below the navel line in the abdomen) every four weeks.
- For the palliative treatment of breast cancer: Zoladex 3.6mg implant injected subcutaneously every four weeks.
- For thinning the lining of the uterus: Zoladex 3.6mg implant injected subcutaneously every four weeks, for up to six months.
