Urticaria is a skin reaction that can appear as an itchy, red rash anywhere on your body. It is characterised by wheals (hives) which are red, raised, swollen patches of skin. Urticaria can be short-lived (24 to 48 hours) or can last longer.
Urticaria can be caused by an allergic or non-allergic reaction. Some people may have an allergic reaction to drugs, food (e.g. shellfish or nuts), preservatives or insect bites. Other people may have a non-allergic reaction to food, food additives or medicines.
Urticaria can also be caused by infection (e.g. sinusitis) or heat, cold, or pressure from elastic in clothing. However, the cause of urticaria is not always identified.
Symptoms of urticaria
wheals are itchy, raised and swollen and can appear anywhere on your body
wheals can be small or large, be different shapes, or they can change shape
wheals can last for hours or days
heat or stress, such as emotional upset, may worsen urticaria
other symptoms, such as fever or swelling on the lips, eyelids, tongue, and throat may be present and require medical attention
See Your Pharmacist or Medical Professional
Seek medical advice urgently if you have any of the following symptoms:
marked swelling, especially in the face, eyes, lips or tongue
wheezing, tight chest or difficulty breathing or swallowing
See your pharmacist or medical professional if:
urticaria lasts longer than 24 to 48 hours
urticaria comes back after treatment
urticaria covers a large area of your body
you have fever or feel generally unwell
urticaria does not respond to treatment, such as an oral antihistamine product
the person with urticaria is a child aged under 12 or is elderly
you are pregnant or breastfeeding; some medicines may not be suitable
you have other medical conditions, such as asthma or eczema, or take other medicines
you have allergies to any medicines or have started taking a new medicine
Treatment Tips
try to identify what triggered the urticaria, such as a food or medicine, and avoid it if possible
if you have a severe reaction, you may need to carry an EpiPen (a PHARMACIST ONLY product) and wear a medical alert bracelet (such as Medic-Alert); ask your doctor or pharmacist for more information
if aspirin appears to trigger urticaria, see a doctor before using any other medicine, such as non-steroidal anti-inflammatory drugs (NSAIDs)
a cool or tepid (slightly warm) shower may be soothing to the rash, but heat may make the itch worse
avoid tight clothes, as pressure may worsen the wheals and itch
cool, moist compresses and moisturising creams, such as aqueous cream, can soothe a rash
Treatment Options
Oral antihistamines
urticaria is caused by the release of histamine in your body
antihistamines block the action of histamine and relieve itching. There are two main types of antihistamine:
older sedating antihistamines that cause drowsiness
newer, non-sedating antihistamines that do not typically cause drowsiness
these products may help if itching is severe and interferes with your sleep
these products may cause drowsiness, sometimes the next day, so it is important you do not drive or operate machinery, and that you avoid alcohol
these products are not recommended in infants under two years old; check product directions for other age groups
sedating antihistamines are not suitable for everyone; check with your pharmacist
if you have other medical conditions, such as glaucoma, epilepsy or prostate problems, or you take antidepressants, check with your pharmacist before taking
these can help relieve total body itchiness and redness
non-sedating antihistamines may rarely cause drowsiness; do not drive or operate machinery if you are affected
