Pharmacist Tips On Using
How to Take: Administer implant by inserting needle at a 30- to 45-degree angle into the anterior abdominal wall below the navel line. Use caution while injecting goserelin into the anterior abdominal wall (due to the proximity of underlying inferior epigastric artery and its branches). Implant may be detected by ultrasound if removal is required. Monitor for signs/symptoms of abdominal hemorrhage. Use extra care when administering goserelin to patients with a low BMI and/or to patients receiving full dose anticoagulation.
You Need to Avoid: Goserelin is an implant; therefore, do not attempt to eliminate air bubbles prior to injection (may displace implant). Do not attempt to aspirate prior to injection; if a large vessel is penetrated, blood will be visualized in the syringe chamber (if vessel is penetrated, withdraw needle, and inject elsewhere with a new syringe). Do not penetrate muscle or peritoneum.
