This a great value, high quality alcohol pre-injection swab. Boxed in 100's.
The swab contains 70% isopropyl alcohol.
Instructions for use:
The swab should be placed just above the intended injection site, and should then be drawn across the injection site once only, and in one direction. The skin should then be allowed to dry naturally prior to injection.
Alcohol swabs must be used correctly if they are to reduce bacterial load on the skin prior to injection.
The reason for the 'only swab in one direction' instruction this is that during the first wipe, the alcohol pre injection swab will become contaminated, and if it is then wiped back over the injection site the bacteria and skin cells it has picked up will be deposited back onto the injection site.
The reason for the 'allow the skin to dry naturally' is that the bacteriacidal effect of the alcohol occurs when the alcohol is partially absorbed by the cell walls of the bacteria, as the alcohol evaporates, it destroys the cell walls, and the bacteria die. Any sort of physical drying of the skin prevents this happening, and also runs the risk of contaminating the injecting site with bacteria from the thing that is being used to do the drying.
Often in medical practice, swabs are not used. This is because studies have found limited effect from the use of swabs.
Some needle and syringe programmes have wondered if this means that they should stop providing swabs. In general it is our view that the provision of swabs is generally well worth continuing with the provision of swabs alongside additional information on the importance of skin hygiene, in particular the washing of injection sites with soap and water prior to injection.
