Eligard is indicated for the treatment of hormone dependent advanced prostate cancer. The recommendations above follow reports of inappropriate technique in Eligard administration process, some of them associated with a lack of clinical efficacy in patients diagnosed with advanced prostate cancer. A number of case reports indicated a lack of efficacy, as they include analytical data of an increase of testosterone levels above the castrate level (≤50 ng/dl) and/or an increase of PSA (prostate-specific antigen) levels. A cumulative review of known cases of medication error events reported revealed a variety of errors during the preparation, mixing and administration of the product. It is very important to review and understand the detailed instructions for appropriate reconstitution and administration of Eligard that are provided in Section 6.6 "Special precautions for disposal and other handling” of the Summary of Product Characteristics and Section 7 "Information for Healthcare Professionals” of the Package Leaflet. These instructions should be read before reconstituting and administering Eligard.
