Penicillin G Potassium is a generic prescription antibiotic used to treat bacterial infections severe enough to require rapid and high levels of penicillin. Also called “benzylpenicillin,” Penicillin G Potassium is a natural penicillin and is highly effective against infections caused by streptococcus (strep) and staphylococcus (staph). Penicillin G Potassium is also used as a first- or second-line antibiotic against anthrax, diphtheria, syphilis, gonorrhea, clostridia, salmonella, and other bacteria
Penicillin G Potassium is prescribed to patients with pneumonia, meningitis, heart infections, lung infections, blood infections, skin infections, and other bacterial infections. Penicillin G Potassium is only used to treat bacterial infections. It is ineffective against viral infections.
Penicillin G Potassium is administered as an intramuscular injection or an intravenous infusion by a healthcare professional. In certain circumstances, Penicillin G Potassium may be injected directly into the lung cavity or spinal canal.
The most common side effects of Penicillin G Potassium are temporary site reactions to the injection such as pain, redness, and swelling. These will pass in a short time. Otherwise, penicillin causes few side effects at normal doses. However, a significant number of people are allergic to penicillin (anywhere from 0.7% to 10% of the population), so patients will be monitored closely when given a Penicillin G Potassium injection.
The most common longer-term side effects include skin rashes and itching. The most serious side effects of Penicillin G Potassium include potassium poisoning or heart failure (at continuous high doses). When Penicillin G Potassium is used to treat spirochete infections (syphilis or Lyme disease), it can cause a life-threatening condition (Jarisch-Herxheimer reaction) when the body fills with the contents of dead bacteria. You will be monitored after the injection for fever, chills, headache, and low blood pressure.
Penicillin G Potassium allergies are common, particularly in patients who have previously been exposed to penicillin. Allergic reactions include hives, rashes, itching, swelling, and difficulty breathing. The most serious allergic reaction is anaphylactic shock, a dangerous and potentially fatal drop in blood pressure. You will be monitored carefully after the injection for any allergic reaction.
