General Precautions: The most common problem with penicillin is possible allergic reaction. If you are allergic to penicillin or cephalosporins, tell your doctor about the allergy. People with asthma, bleeding disorder, clotting disorder, kidney disease and diarrhea associated with antibiotics should report these conditions to their physician. It is also important to tell your doctor about all allergies, including seasonal, food and contact allergies as these allergies could indicate an increased risk of penicillin allergy.

Always take the full course of penicillin to completely cure the bacterial infection. There is a good chance your symptoms will disappear before the full course of antibiotics is completed. This is not an indication that the infection has been cured.
