It could be.: It might. I use a higher dose, but some docs don't. If you have seen no improvement at all (even just a decrease in color of mucus) after 5 days, call MD and discuss. Keflex can help many causes of sinusitis, but not all.

It should be enough: You can upgrade dosage to three times a day ( every eight hours) by day three if you don't see improvement.
