Hello, Welcome to healthcare magic. I understand from your query that you are having acne and are on oral azithromycin and fexofenadine for the same. Azithromycin takes 4- 6 weeks to show good response, to contrrol your acne and shrink them in size. Do give it some more time. Fexofenadine ( Fexy) has no role in acne. It is given for itching and I am not sure why this has been prescribed to you. For your acne, you could also apply a gel containing 1% clindamycin in the morning and a combination gel containing 2.5% benzoyl peroxide/ Adapelene at bedtime. You could get salicylic acid peels done by a dermatologist to hasten the resolution of pimples. This will also help your acne scars. Drink plenty of water. Eat a healthy diet with lots of fruits and vegetables. Avoid fried food and foods high in sugar content. Hope this helps you. Take care.
