Moxifloxacin (Pro Doc): Uses, Side Effects and Dosage

Serious Warnings and Precautions

What is MOXIFLOXACIN used for?

Your doctor has prescribed MOXIFLOXACIN because you have a certain type of bacterial infection.

Antibacterial drugs like MOXIFLOXACIN treat only bacterial infections. They do not treat viral infections such as the common cold. Although you may feel better early in treatment, MOXIFLOXACIN should be used exactly as directed. Misuse or overuse of MOXIFLOXACIN could lead to the growth of bacteria that will not be killed by MOXIFLOXACIN (resistance). This means that MOXIFLOXACIN may not work for you in the future. Do not share your medicine.

How does MOXIFLOXACIN work?

MOXIFLOXACIN is an antibiotic. It kills many of the types of bacteria that can infect the lungs, sinuses, abdomen, and skin.
