yes a z-pac can cause hives or rashes as i know from first hand experience. when i was younger i was prescribed amoxicillin when i had strep throat and an hour or so after taking it i broke out in hives and had to go to the hospital. oddly enough i have taken amoxicillin when i was sick prior to this experience with no allergic reaction. i recommend trying a different antibiotic since there are plenty out there. hope this helps
can a z-pack trigger an alergic reaction. i was never allergic to a medication before but 15 days ago went thru a c-section. i suffered complications and had to receive multiple transfusions and had to get opened back up in order to stop the bleeding cause by a boggy uterus. i was taking percocet ibuprofen iron and stool softner ad recently switched out the percocet for vicotin and started a z pack. i started having either hives or a rash that is severly itchy on my and now have achy joints. what could be the cause?
