Urgent advice: Ask for an urgent GP appointment if:

  • you're an adult and have chickenpox
  • you're pregnant and haven't had chickenpox before and you've been near someone with it
  • you have a weakened immune system and you've been near someone with chickenpox
  • you think your newborn baby has chickenpox

In these situations, your GP can prescribe medicine to prevent complications. You need to take it within 24 hours of the spots coming out.
