Hello and hope you are doing well.
Along with Azithromycin, hope you are taking anti inflammatory medications. If its viral, then it may take longer to settle down. I would advise you to continue these medications and finish the course. In addition you could take OTC multivitamins. Take plenty of warm oral fluids and lots of rest. For further relief from your symptoms you could do warm salt water gargles and stream inhalations. Please ensure to do this prior to your meals.
However, if you develop a fever, or if there is enlargement of the tonsils with pain or if there is white coating on the tonsils, re consult your doctor.
Hope this helped and do keep us posted.
How long have you been taking the Z-Pak?
You need to give the medication time to work.
Not sure how long you've been on it.
If it's been a week or more, go back to your doctor.
