Hive outbreaks can be very itchyDiscover more about this common skin condition, and what you can do to treat your itchy symptoms.

What are hives? What are the symptoms of hives?

Also referred to as urticaria, hives are characterized by an outbreak of red bumps that suddenly show up on skin. Hives can appear anywhere on the body and often cause itching, burning and stinging. Some hives may be small, while others might form alongside  other bumps to create larger swellings.

What causes hives?

The most common causes of hives are foods, medications, and infections. Hives can also be triggered by insect bites. Foods that often bring about hives include dairy, fish, nuts and eggs. Medications such as aspirin and other over­the­counter anti­inflammatories like ibuprofen have also been known to cause hives.

There is another form of hives known as physical urticaria, which is triggered by and external physical factor such as cold, pressure, heat, exercise or sweating. This variety of hives usually appears within an hour after contact with one of these elements.

Are hives dangerous?

The majority of hives outbreaks are not dangerous ­ however, if you also experience dizziness, problems breathing, swelling of the face or tightness in your chest, then you should call for emergency assistance immediately! These can be signs of a life­threatening allergic reaction.

How are hives treated?

If you know what might be triggering your outbreaks, the best thing you can do is remove the trigger right away and avoid it as much as possible. Some people are able to take over­the-counter antihistamines like Benadryl to help relieve the itching. However, those with chronic hives may need to take a stronger antihistamine in combination with corticosteroids.

If you experience a severe outbreak, an epinephrine injection will need to be administered right away. Again, seek medical attention immediately!

To help relieve symptoms until the hives go away, you can also apply cold compresses to the areas to help ease any burning or itching. Also keep your bedroom and living space cool and opt for roomier clothing that won’t rub against the infected areas and exacerbate itching.

How long do hives last?

Some cases of hives clear up in only a few hours, while some can last for a full day before starting to fade.

If you are dealing with a nasty bout of hives that over­the­counter remedies don’t seem to fix, then it might be time to talk to your dermatologist about other treatment options. Call our office to schedule an appointment right away!
