Then flick the side of the syringe with a finger to make the air rise up under the plunger. After the injection, place a finger or dry cotton swab over the site of injection. Hold for a few seconds to prevent any bleeding. Rub the site gently to close the needle track. Press the dry cotton firmly on the site.
Some people put their finger over the site where the needle came out and rub gently.
The finger should be clean. The plastic syringes can be used for two to four days, although we usually don't advise this. The needle may become dull after the second or third shot. If they are to be reused, after giving the injection, push the plunger up and down to get rid of any insulin left in the needle. Wipe the needle off with an alcohol swab.
