Normal saline: How to prepare at home
Normal saline is a sterile mixture of salt and
water. It is called normal because its salt
concentration is similar to tears, blood, and other
body fluids (0.9% saline). It is also called
isotonic solution. Normal saline is soothing and
will not burn or sting when applied. It is used
for:
injecting medicines via the veins (intravenous
infusion)
rinsing contact lenses
rinsing the nasal passages (nasal irrigation)
cleansing the bladder (bladder irrigation)
How to make normal saline solution at

2. Boil for 15 minutes with the lid on (set a

3. Set the pan aside until cooled to a room

saline) from the pan into the jar or bottle

recently washed in a dishwasher with very
hot soapy water

unused solution, wash the container, and
make a new solution.
