When finished, dry off with clean paper towels. If necessary, alcohol hand sanitizer or towelettes may be used instead. Though not always necessary for home irrigation, you can put on disposable latex gloves for extra safety. To prevent infection, only use an unopened, sterile catheter tip syringe unless directed otherwise by your clinician. To make sure that the syringe remains sterile, do not allow the tip of the syringe to touch your skin or any other object. Catheter tip syringes can be purchased at most medical supply stores, drug stores, and supermarkets. They are typically sold in multi-syringe bundles for less than $1 per individual unit. Place the tip of your syringe into a bottle of normal saline solution. Then, pull back on the plunger of the syringe. Continue pulling the plunger until you have filled the syringe with the amount of saline prescribed by your doctor, typically around 10 millilitres (0.35 imp fl oz).  Look for saline solutions at most medical supply and drug stores. They typically cost between $4 and $9 per bottle. If you can't afford saline solution, use an unopened bottle of water instead. Do not use homemade saline solutions since they will increase your chances of infection. While handling the bottle of saline solution, you should only touch the outside of the container. Do not get your fingers on the top or inside of the bottle. Remove the syringe from the saline bottle and hold it vertically. Then, tap on the barrel with your knuckles to loosen any air bubbles. Place the syringe back into the bottle, then carefully push the plunger to get rid of the trapped air. If necessary, pull the plunger back again to replace any lost saline. To make sure it stays sterile, place the tip cover included with your syringe onto the catheter tip. If a cover was not included, place the syringe back into its sterile packaging. Set it aside for later use.
