How to use it

  • A doctor, nurse, or other trained healthcare professional will give you this medicine as an injection into a muscle, joint, or the skin, depending on your condition.
  • Take this medicine exactly as your doctor or another healthcare professional tells you. The amount and how often you receive it will be decided by your care team based on your condition and how you respond.

If you miss a dose

A trained clinician selects the product, dose and injection site; do not self-inject.

Pregnancy and breastfeeding

Missed doses, storage and accidental exposure

  • This medicine is stored and handled by your healthcare provider or pharmacy, so you do not need to store it at home.

Keep the original packaging and follow its storage, expiry and disposal instructions. Keep medicines away from children and pets. Ask about refrigeration, after-opening limits and safe sharps disposal when relevant.

For suspected overdose or accidental swallowing, contact poison control or urgent medical care promptly. Call emergency services for breathing difficulty, collapse or a seizure.

  • Tell any other doctor, dentist, or surgeon that you are receiving this medicine before any procedure or surgery.
