Injuries from needles used in medical procedures are sometimes called needle-stick or sharps injuries.
Some people have an increased risk of needle-stick injuries as a result of their job.
If you injure yourself with a used needle at work, report the incident to your supervisor or manager immediately. There may be procedures in place you need to follow.
If you're at increased risk of needle-stick injuries because of your job, you may also need to take other preventative measures. For example, you may need to have a hepatitis B vaccination.
If you have received treatment for a needle-stick injury, you may need some support. For example, counselling may help with any stress the injury has caused. Your employer's occupational health service can advise you on sick leave.
