How long should I expect my post viral rash to keep breaking me out into random hives?

How long should I expect my post viral rash to keep breaking me out into random hives?

No way to know.: My standard answer to that question is, "my crystal ball is in the shop." urticarial eruptions can persist for days to weeks after the virus is gone; how long is totally unpredictable. A long-acting antihistamine such as fexofenadine (now available otc) can be very helpful until the reaction subsides. ...Read more

My 2yr old has a little bit of hives rash in his whole belly&chest since last night, i gave him children's benedryl last night. How lng wil it go away?

Hives in a 2 year ol: If the child is itching it could be allergic reaction, the hives will keep coming back as long as he is still exposed to the offending agent, red raised blotches that keep coming back could also be erythema infectiosum, a viral illness also known as 5th disease can last for several wks. Your pediatrician can check him & run blood work to make the Dx. Good luck. ...Read more

What causes rashes/hives?

What causes rashes/hives?

Immune system alert: For some reason (often it is mysterious even with best efforts to identify the agent) some people's immune systems go into an emergency alert mode and send out defensive weapons to protect you from what it feels as a threat. Unfortunately, it usually is an over-reaction and causes more problems for you. If your dr agrees - a daily benedryl may help. Be ready with an epi-pin & 911 for emergency! ...Read more
