Thank you.

How long should the patient take azithromycin? Are you a doctor?

Actually the patient got tick bite. The tick was sent to a uni. lab and confirmed that the tick is deer tick with black legs, which can have 60% chance carrying Lyme disease. There is no any symptom yet such as fever etc yet.  She just started to take azithromycin for about 1 week now. Lyme disease is so scary!
Thank you again!
