My 6 year old son was diagnosed with pneumonia the other day. His doctor prescribed Azithromycin to treat it. I gave him one 6 ml dose and 8 hours later, he broke out in a severe rash all over his legs and then it appeared on his arms within minutes. He was very itchy and in agony. I immediately took him to the ER and they told me that this rash was actually hives! The Dr. said it's not unusual for it to take 8 hours to develop the hives since the drug had to work its way throughout his system. They gave him prednisone and benadryl and within an hour, the hives were gone. My son has never had a drug allergy before, but this was his 1st time taking this drug.
Also, important to keep in mind that the medicine stays working in your body for several days after taking it ... since it's one of those that you take for "X" am't of days but continues to work for 10 so that is probably why the rash is continuing if it's allergy to the med.
I would consult with your Dr and if anything life threatening appears like tight throat, signs of anaphylaxis, etc. get immediately to the ER, etc.
The next step is usually prednisone if it doesn't get better. That's what I think

Hi,
I'd touch base with your Dr to be certain it's from the meds? It could be part of whatever you are ill with. I'm not a doctor (a mom of 4 older kids with allergies) and I wonder bout the pistules you mention i that's typical from the antibiotic. Let me do a few image searches and see if I uncover anything for you.
You could try Benadryl topical cream on the bad areas as well as Calimine lotion.
Feel better
