Product introduction
Oson O is a two-in-one antimicrobial tablet that pairs ofloxacin, a fluoroquinolone antibiotic, with ornidazole, an agent active against protozoa and anaerobic bacteria. Because it covers more than one kind of germ, doctors commonly prescribe it for mixed infections such as infectious diarrhoea and dysentery. It is a prescription-only medicine and should be taken exactly as advised.
Storage: Store below 30°C, away from moisture and direct sunlight.

How Oson O Tablet works
Oson O contains two medicines. Ofloxacin stops bacteria from copying and repairing their genetic material, so they cannot multiply and die off. Ornidazole enters parasites and anaerobic bacteria and damages their DNA, killing them. Together they cover a wider range of infection-causing organisms.
