Hello! I am Dr. Aditya and will try my best to answer your question.
Yes it is fine to take your medicines together. Interaction between sertraline and azithromycin is possible but only usually seen in patients with a preexisting heart condition. If you experience palpitations, dizziness, fainting contact your doctor immediately.
Hope you are satisfied!
