Azithromycin 500mg Tablets

Azithromycin 500 mg tablets are prescription antibiotics used to treat certain bacterial infections. They belong to the macrolide (azalide) class of medicines. These tablets work by stopping the growth of bacteria, helping the body fight infections more effectively.

Doctors commonly prescribe the 500 mg strength for respiratory tract infections, throat infections, skin infections, and some sexually transmitted infections. It is not effective against viral illnesses like colds or flu. Because it is a Schedule H medicine in India, it should be taken only under medical supervision and as directed by a registered doctor.
