Off 2 Tablet is a combination medicine which can be used to treat infections caused by bacteria and parasites. It works by killing and stopping the growth of the bacteria and parasites causing the infection. This medicine usually makes you feel better quite quickly. However, you should continue taking it as long as it is prescribed even if you feel better, to make sure that all bacteria and parasites are killed and do not become resistant. Ofloxacin + Ornidazole is a combination of two antibiotics: Ofloxacin and Ornidazole. Ofloxacin works by preventing the bacterial cells from dividing and repairing, thereby killing the bacteria. Ornidazole kills parasites and anaerobic bacteria that cause infections by damaging their DNA. Together, they treat your infection effectively.
