I've taken Cephalexin, 500 MG, 4 times a day for 11 days now. Persicibed by an oral sergeon for swollen gums, infection. Suppose to go under and get some teeth extracted in 6 days. My problem, it's Sat. after midnight, can't talk to my Dentist till Mon. My jaw is still swollen, painful, cant hardly eat, so still have infection, is there a stronger anti-biotic he an give me? Have taken med faithfully every 6 hours, swelling seems to move around alittle and swelling goes down then is back. Getting lots of sleep too. Thax for wasting my time while I'm in such pain, nothing was ever mentioned about $ for an answer, till the very last click. Your just another scam on here.
