Naltrexone implant insertion

Before inserting the Naltrexone Implant (NI), your Doctor will conduct tests to make sure you have not been using any opiate drugs (such as Heroin).

1) You will be asked to give a urine sample

2) You will be given a naloxone test. This is an injection test of a  drug similar to naltrexone, given by injecting into a vein or into your

abdominal fat. Your Doctor will observe you for up to 30 minutes to

check if the naloxone does not make you unwell.

Naltrexone Implant

If there is any doubt that you are opioid-free, the insertion will be delayed at least 24 hours. In this case, the test will be repeated. If there is no evidence of a reaction, the procedure to insert the NI may be started.

The Procedure

  • Following the urine and naloxone tests your Doctor will give you antibiotics to prevent infection. Please tell the Doctor if you are allergic to any particular antibiotics (such as penicillin) and an alternative will be provided.

  • You will be asked to lie down on a surgical table.

  • The doctor will prepare the area where your implant will be inserted (usually on your lower abdomen) and inject a local anaesthetic to numb the area. You may feel some pulling or tugging during the procedure, this is normal.

  • A small incision is made and one sterile implant is inserted.

  • The incision is then closed and dressed.

  • You will remain under observation for 30 minutes.

  • Keep the wound dry and avoid heavy lifting for 7 days.
