Direct healthcare professional communication on the correct method of administration of Reseligo 3.6 mg and 10.8 mg implant in pre-filled syringe (goserelin)


Alvogen d.o.o., in agreement with the Agency for Medicinal Products and Medical Devices (HALMED), has informed healthcare professionals of the correct method of administration of Reseligo 3.6 mg and 10.8 mg implant in pre-filled syringe (goserelin). In order to avoid the incorrect administration or discomfort for a patient during and after administration of Reseligo, attention should be paid to specificities of the syringe for application of the medicinal product and of the method of administration of Reseligo, which are different from the syringe and method of administration of the reference medicinal product.


  • When administering Reseligo, the needle is inserted into the subcutaneous tissue obliquely (almost parallel to skin), which differs from the angle at which the reference medicinal product is applied. The needle is inserted until the syringe barrel touches the patient's skin. This contact with the skin must remain during the entire application process.
  • In contrast to the reference medicinal product, the syringe for application of Reseligo is equipped with an integrated automatic system for the retraction of the needle from tissue and the protection of healthcare professionals from needle-stick injuries.
  • After inserting the needle, the syringe plunger should be pressed down which transfers the implant to the tip of the needle, and the needle is automatically retracted from tissue. The syringe of Reseligo should not be pulled out during application. The syringe barrel must remain in contact with the skin during administration.
  • If the syringe of Reseligo is actively retracted from the skin during administration, the administration has not been completed and incorrect use or discomfort for a patient can occur.
