This may vary depending on the type of infection you have. For example a dose of 250mg (1 × 250mg tablet) taken every 6 hours or 500mg (2 × 250mg tablets or 1 × 500mg tablet) every 12 hours is used to treat skin, soft tissue, throat or urinary tract infections, or those caused by less susceptible organisms.
