Sinusitis
"I have been on this for 5 days, sort of working, still have the headache though.  I haven&#039;t really had any side affects yet.  But I was given a 21 day dosage for (2) 300mg capsules.  I have had 4 sinus infections since January.  Hope it helps get rid of the headache.  It has helped with the drainage and coughing though."
