Ways to inject - with or without a needle

Growth hormone is available in different delivery systems.

Growth hormone cannot be taken by mouth because it is broken down by acids in the stomach. Instead it is given through the skin (by a method called subcutaneous injection) and from there, it is absorbed into the bloodstream.

There are two main types of delivery systems: 

  • Needle – a very thin needle is used to deliver the growth hormone.
  • Needle free - the growth hormone is pushed through the skin using high pressure, but no needles.

Delivery with a needle

When the injection is given with a needle, the growth hormone is injected just below the skin into what is known as the subcutaneous tissue. From here, the growth hormone is evenly absorbed into the bloodstream. 

Delivery with a needle free system

Needle free systems use high pressure to push thin streams of the growth hormone through the skin. The growth hormone is then absorbed through the skin and into the bloodstream. 

Using a needle free system may be helpful if your child has a fear of needles and is struggling with treatment. Speak to your doctor about what options are available for your child. 

If your child is about to start growth hormone treatment use our checklist to help you to make sure you are well prepared.
