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.
