Tips on learning self injections

Home Treatments Lifestyle Symptoms Cancers

 

A number of cancer treatments involve the regular administration of drugs under the skin (subcutaneous injection). This is because the drug to be injected is a protein and would get broken down by the digestive system. This page gives advice from professionals and patients themselves on how to injection yourself. This advice also applies to family or carers who want to learn to give injections. Any injection is not a pleasant thought but learning how to inject oneself or someone you are caring for  has some major benefits:-

 

Which treatments require injection under the skin?. Most patients requiring insulin in the UK have learnt to self inject but for cancer therapies the injections are usually only for short periods of time so it may not be worth learning in many cases. Certainly you should not regard yourself as failing if you don't want to do it or can't manage it. Treatments in oncology which involve subcutaneous injection include:-

How to self inject

Before you start you prepare for the injection. On a clean flat surface have a your equipment ready. Many injection are supplied in a pack containing a prefilled syringe. Check the "use-by" date and ensure the contents are all present. Have a skin swab and "sharps box" ready.

Wash hands.

Ensure injection site is clean and dry.

Hold the syringe like a pencil and remove needle guard.

Pinch the skin where you are going to inject.

Wipe the skin with an alcohol swab and allow to dry.

Draw back the plunger a little: if blood comes up into the syringe, you have touched a small blood vessel; remove the needle and syringe and throw away in sharps bin. Prepare a new injection, ensuring you inject into a new site;

if no blood appears, slowly push plunger to inject solution.

When syringe is empty, remove needle and syringe and press on site for at least one minute with a swab or cotton wool. Don't worry if it bleeds a little as that is normal. Put a plaster on the site if you wish.

Put the needle and syringe into the sharps bin.

When your sharps bin is half to two thirds full, shut and lock the lid and return it to your GP or clinic. Please do not over fill it.

 

Inserting a continuous butterfly needle

Tips from a patient to other patients about giving self-injections in relation to the syringe pump

Hold the butterfly needle firmly at 45 degrees in right hand (if right handed) and in the left hand firmly grip between thumb and forefinger, a lump of fatty flesh on the abdomen or thigh and briskly puncture the skin with the needle.
Slide it steadily into position up to the point of the green ‘wings’ of the butterfly. If the initial puncture is done quickly the pain is negligible (it is only the thought of it – you may find which inhibits the correct action?)
If the puncture is done slowly, there is a build-up of resistance in front of the needle which may result in pain, because this is communicated back though the nervous system…
Take it by ‘surprise’ as it were and you will have no problems – just a quick jab and in.

Sometimes you may experience problems with the syringe pump, which causes it to stop – this can be for the following reasons:-
