Penicillin was the first antibiotic but later on, it was found that many patients are allergic to this antibiotic, therefore, other safe alternatives have been discovered for penicillin allergic patients. These alternatives were ampicillin, amoxicillin, and benzylpenicillin etc. There are many other antibiotics but doctor’s prescription is essential in order to use them.
