Things you can do to help boils

There are things you can do to treat boils yourself and stop them coming back.

Do

  • soak a clean cloth in warm water and hold it against the boil for 10 minutes 4 times a day

  • clean the area around the boil with antibacterial soap if pus comes out

  • cover the area with a dressing or gauze until it heals

  • bathe or shower every day and wash your hands regularly

  • take paracetamol or ibuprofen to ease the pain

  • wash your towels and bedding at least once a week at high temperature

  • try to lose weight if you are very overweight and have boils between folds of your skin

Don’t

  • do not pick, squeeze or pierce a boil

  • do not share your towel with other people until the boil has gone

  • do not go to a swimming pool or gym until the boil has gone –⁠ you could pass the infection on to others

Non-urgent advice: See a GP if:

  • you've had a boil for 2 weeks and the things you've tried are not helping
  • you keep getting boils
  • you have a group of boils (carbuncle)

Urgent advice: Ask for an urgent GP appointment or get help from NHS 111 if you have a boil and:

  • it is on your face
  • the skin around your boil feels hot, painful and swollen
  • you feel hot and shivery
  • you have a weakened immune system – this could be from taking treatments such as steroids, or having a condition like diabetes

You can call 111 or get help from NHS 111 online.
