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.

Treatment for hives from a GP

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 cannot always prevent hives

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:

eating certain foods
contact with certain plants, animals, chemicals and latex
cold, such as cold water or wind
hot, sweaty skin from exercise, emotional stress or eating spicy food
a reaction to a medicine, insect bite or sting
scratching or pressing on your skin, such as wearing itchy or tight clothing
an infection
a problem with your immune system
water or sunlight, but this is rare

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.
