Hello;
welcome to HealthcareMagic
Azithral is a antibiotic and so if you are sensitive to a antibiotic then you can get a
allergic reaction but it will happen as soon as you take the first doseand it will be generalised all over the body anywhere and not at a specific place .So if you have itching after you have finished the course of medicine then you need to consult your doctor as it may not be due to Azithral.
Thanks
