Key takeaways
Cefpodoxime (Vantin) and penicillin (Penicillin VK) are antibiotics, but they belong to different classes. Cefpodoxime is a cephalosporin antibiotic used to treat a variety of bacterial infections in adults and children, including strep throat, sinus infections, and pneumonia. It is taken twice daily and is available in both tablet and liquid forms. Penicillin, on the other hand, is a penicillin antibiotic primarily used for strep infections, certain types of pneumonia, and staph skin infections. It is usually taken every 6 to 8 hours and is available as a low-cost generic. One major difference is that penicillin is often less effective due to bacterial resistance, whereas cefpodoxime can be an option if you have a mild penicillin allergy. However, both medications can cause diarrhea and severe allergic reactions, especially if you have a history of allergies to beta-lactam antibiotics. It's important to complete the full course of either antibiotic to prevent resistance.
