Remove the needle from the syringe, discard, and attach a new, unused sterile needle to the syringe. If the needle breaks during injection and you are able to see and grasp the broken end, you should remove it and contact your healthcare provider. If you cannot see or cannot grasp the broken end, you should promptly contact your healthcare provider.
