Side Effects of Penicillin
Penicillins are typically very safe; the greatest risk being allergic reaction, which, when it occurs, can be severe. People who are allergic to penicillin may also have an allergic reaction to cephalosporins, another type of beta-lactam antibiotic.

The most common side effects of penicillin are mild diarrhea, headache, sore mouth or tongue, vaginal itching and discharge, white patches (yeast) in the mouth and/or on the tongue. 


​Gastric Breakdown & Absorption
Penicillin can be broken down in the stomach by gastric acids and is irregularly absorbed from the intestines into the blood stream.

This is an example of a type of antibiotic resistance. Penicillins are sometimes combined with beta-lactamase inhibitors, agents that protect the penicillin from these bacterial enzymes.

Bacterial Enzymes & Antibiotic Resistance
Many pathogenic Gram-positive bacteria produce enzymes called Penicillinases (or beta-lactamases) that can inactivate penicillin. The capability of bacteria to synthesize this enzyme is an adaptation that was selected for in the presence of substances that inhibit bacterial growth.
