Why is pencillin rarely used today?

Penicillin is rarely used today due to the widespread emergence of antibiotic-resistant bacteria, which have evolved to survive treatments that were once effective. Additionally, the development of newer antibiotics with broader efficacy and the ability to target specific infections has led to a decline in penicillin's use. Furthermore, some patients may be allergic to penicillin, limiting its applicability. As a result, healthcare providers often prefer alternative antibiotics for treating bacterial infections.
