This information is intended only for healthcare professionals:

Zoladex Trimestral 10.8 mg should be administered via subcutaneous injection - read and understand all instructions completely before administration.

  1. Place the patient in a comfortable position, with the upper body slightly elevated. Clean the abdominal injection site with a cotton swab impregnated with a disinfectant agent (alcohol, etc...).

NOTE: Caution should be exercised when administering Zoladex Trimestral 10.8 mg in the anterior abdominal wall, due to the proximity of the underlying inferior epigastric artery and its branches. Very thin patients may have a high risk of vascular injury.

  1. Examine the envelope and syringe for damage. Remove the syringe from the open envelope and hold it at an angle towards the light.

Check that part of the Zoladex Trimestral 10.8 mg implant is visible. (Figure 1).

  1. Gently remove the blue plastic safety tab from the syringe and discard it. (Figure 2).

Remove the cap that protects the needle. As it is not a liquid injectable, there is no need to eliminate air bubbles, as attempting to do so may cause the Zoladex Trimestral 10.8 mg implant to shift.

  1. Hold the syringe around the protection system, using an aseptic technique. Take a skin fold of the patient and insert the needle at a slight angle (30 to 45 degrees).

With the needle opening facing up, insert the needle into the subcutaneous tissueof the anterior abdominal wall below the navel, until the protection system touches the patient's skin. (Figure 3).

NOTE: The Zoladex Trimestral 10.8 mg syringe cannot be used for aspiration. If the hypodermic needle penetrates a large vessel, blood will be seen immediately in the syringe chamber. If a vessel is penetrated, remove the needle and control any resulting bleeding, monitoring the patient for any signs or symptoms of abdominal bleeding. After ensuring the patient is hemodynamically stable, another Zoladex Trimestral 10.8 mg implant can be injected with a new syringe in another area. Exercise caution when administering Zoladex Trimestral 10.8 mg in patients with a low BMI and/or those receiving full anticoagulant doses.

  1. Do not penetrate the muscle or peritoneum. In Figure 4, below, an incorrect grip and exposure angle are shown.

  1. Press the plunger completely, until it cannot be pressed further, in order to deposit the Zoladex Trimestral 10.8 mg implant and activate the protection system. You may hear a "click" and feel the protection system activate, sliding automatically to cover the needle. If the plunger is not pressed completely, the protection system WILL NOT activate.

NOTE:The needle does not retract.

  1. Continue holding the syringe as shown in Figure 5, remove the needle, allowing the protection system to continue sliding and covering the needle.

Discard the syringe in a container, in accordance with local regulations.
