A home for their hearts Posted February 27, 2011 Share Posted February 27, 2011 My ds9months has a sinus infection and was prescribed amoxicillin after giving him 2 doses he broke out in hives yesterday. The doc prescribed him something else but he still has hives. Would this be a new reaction to the new drug or would there still be some amoxicillion in his system after 24 hours?

lisamarie Posted February 27, 2011 Share Posted February 27, 2011 DH reacted to a med he was taking and the dr said it could take up to 2 weeks for it to fully clear his system and for the hives to go away. I want to say that it took a good week for the hives to leave. I reacted to ibuprofen and it took 3-4 days for the hives to clear up. It's not instantaneous, unfortunately.

akmommy Posted February 27, 2011 Share Posted February 27, 2011 When my DD got hives from ceclor she continued to have outbreaks for almost three weeks. Anytime something would irritate her skin, like clothing tags, hives would develop. I was told this was normal. Quote Link to comment Share on other sites More sharing options...

Harriet Vane Posted February 27, 2011 Share Posted February 27, 2011 An allergic reaction can continue for 4-6 weeks. Generally you will need to stay continually on antihistamines the first 3-5 days, after which you can expect to dose with an antihistamine as symptoms (hives, whatever) crop up. Over time the reactions will decrease in frequency. Quote Link to comment Share on other sites More sharing options...
RoundAbout Posted February 27, 2011 Share Posted February 27, 2011 When we found out my son was allergic it looked significantly better after 24 hours but took a few days to completely clear up. Quote Link to comment Share on other sites More sharing options...
Quad Shot Academy Posted February 27, 2011 Share Posted February 27, 2011 When my son reacted to Amox, it took a week, with Keflex, it took 6. :crying: It is a real issue to know whether he is reacting to the new antibiotic or not. :grouphug: Quote Link to comment Share on other sites More sharing options...

It would probably help, not only is he sick now he is probably itchy all over! Poor baby he's just miserable! Quote Link to comment Share on other sites More sharing options...
AndyJoy Posted February 27, 2011 Share Posted February 27, 2011 My dh's hives from Amoxicillin lasted several weeks. Poor baby! Dh was pretty miserable for the first few days at least. Quote Link to comment Share on other sites More sharing options...
AngieW in Texas Posted February 27, 2011 Share Posted February 27, 2011 When my middle dd reacted to Amoxicillin, it took about 10 days for the rash to go away. Quote Link to comment Share on other sites More sharing options...
ChristineW Posted February 27, 2011 Share Posted February 27, 2011 When my DS5 was 14 mos he had the amoxycillin rash. It took about 10 days for it to clear up. It got worse for about 2 days after he stopped taking the antibiotic. I'm pretty sure the dr had us give him benadryl. Christine Quote Link to comment Share on other sites More sharing options...
Quad Shot Academy Posted February 27, 2011 Share Posted February 27, 2011 We did Benadryl and Zyrtec around the clock. Quote Link to comment Share on other sites More sharing options...
