How long Do Hives Normally Last?

How long should hives last from a medication?

• I took Prilosec for GERD (acid reflux) symptoms, and it was working; took for 4 days (skipped one day, but in total it was 4 days of taking it) and I had to stop taking it because the top parts of my arms broke out into hives, was hot and itchy. I stopped taking the pills I believe last Sunday, so it has been a week, and I still have redness and itchiness on my arms - though it is now on the bottom parts of my arms and my hands. It does not look as bad as it did, but it still pops up. Is this normal for it to still be on my arms after a week? How long does it take for a drug to get out of your system? Any help would be greatly appreciated.

• Answer:

  I've gotten hives a couple of times from an allergic reaction like yours, it took a couple of weeks for them to be gone completely. The problem is because it was something you took, it has gotten into your blood stream and it takes a while for your body to fully flush it out.
