Help? Will penicillin cause a reaction or overdose when administered immediately after amoxicillin was taken ?// Patient is 4 yrs old, ear infections. Her mother gave her amoxicillin and then a neighbor gave her penidillin>>>>>A worried grandma !!!

Probably not. Antibiotics are often given as a double dose, though usually at the beginning of the course. Amoxicillin and Penicillin both belong to the same family of drugs (penicillins) and they really only cause problems in people who have allergies to penicillins.

Thanks for reply Lefty. how about mixing amoxicillin and Tylenol w) codeine , same child, age 4 , I found out it was not penicillin but tylenol with codeine that was given to her.
