Depends on trigger: Urticaria (hives) is common, affecting up to 20% of the population. Acute hives is defined as periodic outbreaks of red, raised itchy lesions that resolve within 6 weeks. Common viral and bacterial infections can trigger an outbreak, however medications, foods, and insect stings can also cause acute hives but have the potential to lead to more serious complications.

I'm 7 weeks pregnant and suddenly developed horrible hives all over my arms and legs.. Do they go away after my body is use to the hormone change?

Possibly: Pregnancy can cause all sorts of hormonal and other changes. Cetirizine and Loratadine are pregnancy class b, so these can be safely used during the pregnancy if the hives do not resolve on their own within a short period of time. Your OB and allergist can work together to help in this circumstance.

Probably not!: You have to have the child seen by an allergist to see if something is triggering hives. Sometimes there is no good explantation for the hives but if zyrtec (cetirizine) is not helping it needs to be evaluated.

See your Doc: Hives can be very annoying and distressing to deal with. For hives that persist or are particularly troublesome one should consider see a physician who is interested in this problem -- typically an allergist.

Sure, i've heard of hives. But now that my child may have it, I want to know what it really does to the body.?

Hives: Usually just uncomfortable and sometimes unsightly. Most times hives will burn out, never to return. Sometimes they fester or will come & go intermittently. Antihistamines are best for suppression. Long term side effects from hives are not something to worry about. If you are worried, definitely see an allergist to test for what might be the causative factor to get it treated.

? Chronic urticaria: May be also physical urticaria, or something at work that triggers your symptoms, stress can, keep taking a second generation antihistamine regularly if you're already taking it as needed, or start an OTC one, unless contraindicate. See an allergist/ dermatologist, check aaaai.org or acaai.org for an allergist in your area, good luck
