i was prescribed amoxicillin (sp.) because of a respitory infection...they didn't know if it was a virus or a bacterial infection but since I was flying to Hawaii, they thought it best to take the amoxicillin. On the last day of taking the medication, I woke up with a rash on my arms, back, legs and face. I then started taking benedryl, thinking I was having an allergic reaction. It is now 3 days later, the rash is fading but now my lips are numb....so, is this another reaction to the amoxicillin or to the benedryl??? I am allergic to sulfa drugs. I would appreciate your opinion. Thank you. Cheryll Schramm
