Key takeaways
Cefditoren (Spectracef) and penicillin V potassium (Penicillin VK) are both antibiotics used to treat bacterial infections, including those affecting the respiratory tract. However, they belong to different medication classes. Cefditoren is a third-generation cephalosporin antibiotic, while penicillin V potassium is a penicillin antibiotic. Cefditoren is no longer available in the U.S., whereas penicillin V potassium is still available by prescription. Penicillin V potassium is used for a wider range of infections, including strep throat, scarlet fever, and skin infections, and it can also prevent rheumatic fever and heart valve infections. It is available in tablet and suspension forms and is typically taken every 6 to 12 hours. Common side effects of penicillin V potassium include nausea, vomiting, and diarrhea, and it can cause serious allergic reactions in people with penicillin allergies. In contrast, cefditoren's availability and specific side effects are not detailed, as it has been discontinued.
