The injection process

Where?

Zoladex is an implant which is injected under the skin, using a needle. You should only feel a little bit of pain.1

Usually the injection will be given under your skin, around the stomach area. You may be able to feel the implant under your skin, but it will dissolve over time, releasing the medicine into your body. It is completely normal to be able to feel the implant under the skin, so don’t worry if you can.

 

Who gives the injection?

The injection can be given either by your nurse, GP or hospital doctor.

 

How often?

Zoladex implants are available in two strengths 3.6 mg and 10.8 mg.2,3 Because the medicine is released gradually, injections only need to be given either every 4 weeks for the 3.6 mg implant or every 12 weeks for the 10.8 mg implant.

 

Fear of needles

Many people have a fear of needles – it is very common. However, treatments like Zoladex are only available as injections. Zoladex has been designed to release the medication slowly over time so that it keeps your testosterone levels low throughout the day. Unfortunately, this can only be achieved with an injected implant.

A good thing about the injection is that you don’t have to remember to take tablets every day and the risk of forgetting to take your medicine is removed. Once the implant is in place, you can forget about it and get on with your everyday life.

You only need to have the injection every 4 weeks for the 3.6 mg implant or every 12 weeks for the 10.8 mg implant.

Missing an appointment

It is very important to have your Zoladex injection at the right time, so that your testosterone levels stay low.

You should make every effort to plan holidays and trips around your injection appointments. If you already have something booked that clashes with your next injection appointment, you should speak to your GP or nurse as soon as you can.

Reporting of side effects

Like all medicines, Zoladex can cause side effects, although not everybody gets them.

If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in the package leaflet. You can also report side effects directly via the Yellow Card Scheme, Website: www.mhra.gov.uk/yellowcard. By reporting side effects you can help provide more information on the safety of this medicine.
