Hives

Check if it's hives

The main symptom of hives is an itchy rash.

The rash can:

be raised bumps or patches in many shapes and sizes
appear anywhere on the body
be on 1 area or spread across the body
feel itchy, sting or burn
look pink or red when affecting someone with white skin; the colour of the rash can be harder to see on brown and black skin

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.

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.

A GP might prescribe menthol cream, antihistamines or steroid tablets.

If hives does not go away with treatment, you may be referred to a skin specialist (dermatologist).

You get hives when something causes high levels of histamine and other chemicals to be released in your skin. This is known as a trigger.

Triggers can include:

Try to find out what triggers hives for you, so you can avoid those triggers, if possible. This may help prevent an episode of hives.
