A pharmacist can help with hives

A pharmacist can give you advice about antihistamine treatment to help a hives rash.

Tell the pharmacist if you have a long-term condition, because you might not be able to take antihistamines.

This treatment might not be suitable for young children.

Non-urgent advice: Ask for an urgent GP appointment or get help from NHS 111 if:

  • symptoms of hives do not improve after 2 days
  • you're worried about your child's hives
  • the rash is spreading
  • hives keeps coming back (you may be allergic to something)
  • you also have a high temperature and feel unwell
  • you also have swelling under your skin (this might be angioedema)

You can call 111 or get help from 111 online.

Immediate action required: Call 999 if:

  • your lips, mouth, throat or tongue suddenly become swollen
  • you're breathing very fast or struggling to breathe (you may become very wheezy or feel like you're choking or gasping for air)
  • your throat feels tight or you're struggling to swallow
  • your skin, tongue or lips turn blue, grey or pale (if you have black or brown skin, this may be easier to see on the palms of your hands or soles of your feet)
  • you suddenly become very confused, drowsy or dizzy
  • someone faints and cannot be woken up
  • a child is limp, floppy or not responding like they normally do (their head may fall to the side, backwards or forwards, or they may find it difficult to lift their head or focus on your face)

You or the person who's unwell may also have a rash that's swollen, raised or itchy.

These can be signs of a serious allergic reaction and may need immediate treatment in hospital.
