Storage & safe handling

Mix with bacteriostatic water: let it run slowly down the inside of the vial and swirl gently — never shake.
Store the mixed vial in the fridge and follow the use-by period on the label.
Wipe the vial top with alcohol and use a new sterile needle and syringe every time.
Rotate injection sites so the same spot is not used again and again.
Put used needles in a sharps container, not the household bin.
Get medical help for redness that spreads, fever, swelling or trouble breathing.
