We have been down that rabbit hole with my oldest. He is allergic to Keflex and one other antibiotic looch on "Has your LO ever developed a late allergy to a med?" https://boards.hellobee.com/topic/when-did-your-lo-develop-a-late-allergy-to-a-med#post-2521017 Mon, 11 Apr 2016 06:52:07 +0000 looch 2521017@https://boards.hellobee.com/ This happened to my son while on amoxicillin for an ear infection. It was the second round, day 9 when he developed a rash that looked a lot like Fifth's Disease.

Our littlest is on day 8 of Augmentin and has a slight rash (normal reaction - not allergic). It's all so interesting, you'd think the body would react right away. lemondrop on "Has your LO ever developed a late allergy to a med?" https://boards.hellobee.com/topic/when-did-your-lo-develop-a-late-allergy-to-a-med#post-2520975 Sun, 10 Apr 2016 22:15:28 +0000 lemondrop 2520975@https://boards.hellobee.com/ Happened to me too with penicillin-V after my wisdom teeth were removed. I was so miserable! The doctor said I have a penicillin allergy.

We stopped it as soon as we suspected it was causing the hives, and they cleared up the same day. sapphire on "Has your LO ever developed a late allergy to a med?" https://boards.hellobee.com/topic/when-did-your-lo-develop-a-late-allergy-to-a-med#post-2520820 Sun, 10 Apr 2016 15:21:15 +0000 sapphire 2520820@https://boards.hellobee.com/ That is common for rash (non anaphylactic) allergies for it to appear 7-10 days later. mrsjyw on "Has your LO ever developed a late allergy to a med?" https://boards.hellobee.com/topic/when-did-your-lo-develop-a-late-allergy-to-a-med#post-2520790 Sun, 10 Apr 2016 13:53:39 +0000 mrsjyw 2520790@https://boards.hellobee.com/ Yep he broke out into gives all over his body after a ten day course of amoxicillin. Took him in and then had him on steroids for a few days Canoli on "Has your LO ever developed a late allergy to a med?" https://boards.hellobee.com/topic/when-did-your-lo-develop-a-late-allergy-to-a-med#post-2520787 Sun, 10 Apr 2016 13:48:26 +0000 Canoli 2520787@https://boards.hellobee.com/ My oldest developed hives on day 8 and 10 of amoxicillin one time and he has taken it a million times. That was his only symptom and has been on it since and it didn't happen again so we don't believe it was an allergy. I know our ped says sometimes hives and rashes can occur because of illness. It's so hard to pinpoint hives and rashes sometimes. The fact that she dizziness and swelling would make me think possible allergy. Hope she gets better and you're able to figure it out. gotkimchi on "Has your LO ever developed a late allergy to a med?" https://boards.hellobee.com/topic/when-did-your-lo-develop-a-late-allergy-to-a-med#post-2520785 Sun, 10 Apr 2016 13:46:29 +0000 gotkimchi 2520785@https://boards.hellobee.com/ @autumnlove: this is actually a very typical presentation for antibiotic allergies - I'd hold any more doses and see what the md wants to do.

This happened after her dose this morning. I called her dr and left a message. Has your LO ever experienced a late side effect to a med?
