Will amoxicillin cause stephen johnson syndrome i going to family dr face swollen i think tooth infection but med phobic bad and dental phobia ?

Probably Not : Stephens-Johnson syndrome is a rare disease that affects fewer than six people per million per year. Unless you have had SJS before, with amoxicillin or another drug, the chances you will get it are vanishingly small. See your dentist immediately. Perhaps he can treat you without giving you an antibiotic. He can definitely avoid amoxicillin if this is a worry for you. Good luck
