I have had oral side effects of two gout meds in the past, resulting in Stevens-Johnson syndrome. On Dec. 2nd I was seen for an URI/ Acute Asthmatic Bronchitis and was put on ceftin 500 Bid X Ten days. Near the end of the dosage I noticed sores in my mouth, lesion like areas and periodic blood blisters to the inside cheek area, it has continued after completion of the ATB. Swallowing is very painful. Am using 2 different oral rinses to help with the pain an for better oral hygiene. Every time I brush, the gums bleed, any advice?
